In recent years, recognition has grown of the significant role that food systems play in driving climate change, constituting about one-third of global greenhouse gas emissions, while also playing a key role in sequestering carbon and adapting to climate changes. The COP28 climate conference signaled a pivotal shift, spotlighting food and agriculture in discourse. However, despite pledges and declarations, concrete plans and targets to address emissions from food chains remain elusive. Urgent action is imperative to transform food systems and avert surpassing critical warming thresholds. [ABSTRACT FROM AUTHOR]

Background: Active school transportation (AST) is an important source of physical activity for children and a potentially important climate change mitigation strategy. However, few studies have examined factors associated with AST in the context of the COVID-19 pandemic. Methods: We used baseline data from a longitudinal survey to investigate correlates of AST during the second wave of COVID-19 (December 2020). We collected survey data from 2291 parents of 7- to 12-year-olds across Canada and linked this information with data on neighborhood walkability and weather from national databases. We assessed potential correlates representing multiple levels of influence of the social–ecological model. We used gender-stratified binary logistic regression models to determine the correlates of children's travel mode to/from school (dichotomized as active vs motorized), while controlling for household income. We examined the correlates of travel mode for both the morning and afternoon trips. Results: Consistent correlates of AST among Canadian children during the COVID-19 pandemic included greater independent mobility, warmer outdoor temperature, having a parent who actively commuted to work or school, living in a household owning fewer vehicles, and living in a more walkable neighborhood. These findings were largely consistent between boys and girls and between morning and afternoon school trips. Conclusions: Policymakers, urban planners, and public health workers aiming to promote AST should focus on these correlates while ensuring that neighborhoods are safe for children. Future research should monitor the prevalence and correlates of AST as COVID-19 restrictions are removed. [ABSTRACT FROM AUTHOR]

Background: Calls to action addressing the interconnections between physical (in)activity and the climate crisis are increasing. The current study aimed to investigate public support for policy actions that potentially have co-benefits for physical activity promotion and climate change mitigation. Methods: In 2023, a survey through the Angus Reid Forum was completed by 2507 adults living in Canada. Binary logistic regressions were conducted. Separate models were created to reflect support or opposition to the 8 included policy items. Several covariates were included in the models including age, gender, political orientation, physical activity levels, income, urbanicity climate anxiety, and attitudes surrounding physical activity and climate change. The data were weighted to reflect the gender, age, and regional composition of the country. Results: Most individuals living in Canada strongly or moderately supported all actions (ranging from 71% to 85%). Meeting the physical activity guidelines, higher self-reported income, and scoring high on personal experience of climate change were associated with higher odds of supporting the policy actions related to climate actions. Conclusions: Most adults living in Canada support policies that align with the recommended policy actions related to physical activity and climate change. National campaigns enhancing awareness and understanding of the bidirectional relationship between physical activity and climate change are warranted, and these should consider the consistent demographic differences (eg, gender, age, and political orientation) seen in public support for physical activity-related policies.

Young Americans are coming of age immersed in daily news and controversy about rising perils like climate change, and emerging ones like artificial intelligence. Generation Z has produced and embraced movements for climate action like the school strikes led by Greta Thunberg that connect to other social justice movements. But the threat posed by nuclear weapons remains a disconnected abstraction to many young people, even as tensions between nuclear-armed states over conflicts like the invasions of Ukraine and Gaza renew fears of a nuclear confrontation that were more common decades ago. In this personal essay, a life-long opponent of nuclear weapons raised during the Cold War reflects on intergenerational lessons about activism, and teaching college students to embrace their curiosity, and their fear, on the way to saving the world.

Stabilizing climate requires reducing greenhouse gas (GHG) emissions and storing atmospheric carbon dioxide (CO2) in land or ocean systems. Soil management practices can reduce GHG emissions or sequester atmospheric CO2 into inorganic and organic forms. However, whether soil carbon strategies represent a viable and impactful climate mitigation pathway is uncertain. A specific question concerns the role that land-management practices and soil amendments can play in realizing California’s ambition for carbon neutrality by 2045. Here we examine the carbon flux impacts of soil conservation (i.e., compost, reduced tillage, cover crop) and enhanced silicate rock weathering (EW) practices at different areal extents of implementation in cropland, grassland, and savanna in California under two climate change cases. We show that with implementation areas of 15% or 50% of private cultivated land, grassland, and savanna in California, soil conservation practices alone can contribute 1.4 0.7 2.1 % ( − 1.8 − 0.9 − 2.7 Mt CO2eq y−1) and 4.6 2.3 6.9 % ( − 6.0 − 3.0 − 8.9 Mt CO2eq y−1) of the additional emissions reduction needed (beyond previous targets) to meet the 2045 net neutrality goal (−129.3 Mt CO2eq y−1), respectively, on an average annual basis, including climate uncertainty. Including EW in these scenarios increases the total contributions of management practices to 4.1 2.5 5.6 % ( − 5.2 − 3.2 − 7.3 Mt CO2eq y−1) and 13.5 8.2 18.6 % ( − 17.5 − 10.7 − 24.2 Mt CO2eq y−1), respectively, of this reduction. This highlights that the extent of implementation area is a major factor in determining benefits and that EW has the potential to make a real contribution to net reduction targets. Results are similar across climate cases, indicating that contemporary field data can be used to make future projections. With EW there remains mechanistic uncertainties, however, such as rock dissolution rate and environmental controls on weathering products, which require additional field research to improve understanding of the technological efficacy of this approach for California’s 2045 carbon neutrality goal.

Contemporary resource management is doubly burdened by high rates of organic material disposal in landfills, generating potent greenhouse gases (GHG), and globally degraded soils, which threaten future food security. Expansion of composting can provide a resilient alternative, by avoiding landfill GHG emissions, returning valuable nutrients to the soil to ensure continued agricultural production, and sequestering carbon while supporting local communities. Recognizing this opportunity, California has set ambitious organics diversion targets in the Short-Lived Climate Pollutant Law (SB1383) which will require significant increases (5 to 8 million tonnes per year) in organic material processing capacity. This paper develops a spatial optimization model to consider how to handle this flow of additional material while achieving myriad social and ecological benefits through compost production. We consider community-based and on-farm facilities alongside centralized, large-scale infrastructure to explore decentralized and diversified alternative futures of composting infrastructure in the state of California. We find using a diversity of facilities would provide opportunity for cost savings while achieving significant emissions reductions of approximately 3.4 ± 1 MMT CO2e and demonstrate that it is possible to incorporate community protection into compost infrastructure planning while meeting economic and environmental objectives.

The article discusses the importance of incorporating climate education in business curricula and highlights the challenges faced by educators in doing so. It introduces En-ROADS, a computer simulation model developed by Climate Interactive, the MIT-Sloan Sustainability Initiative, and Ventana Systems, as a promising tool for experiential learning about climate change and the role of businesses in addressing it. The simulation allows participants to propose actions that can mitigate climate change and assess their impact on global temperatures and equity considerations. The article emphasizes the effectiveness of En-ROADS in increasing knowledge, engagement, and optimism towards climate action, and highlights its versatility and availability as open-source software.

Renewable power generation is the key to decarbonizing the electricity system. Wind power is the fastest-growing renewable source of electricity in the United States. However, expanding wind capacity often faces local opposition, partly due to a perceived visual disamenity from large wind turbines. Here, we provide a US-wide assessment of the externality costs of wind power generation through the visibility impact on property values. To this end, we create a database on wind turbine visibility, combining information on the site and height of each utility-scale turbine having fed power into the U.S. grid, with a high-resolution elevation map to account for the underlying topography of the landscape. Building on hedonic valuation theory, we statistically estimate the impact of wind turbine visibility on home values, informed by data from the majority of home sales in the United States since 1997. We find that on average, wind turbine visibility negatively affects home values in an economically and statistically significant way in close proximity ([Formula: see text]5 miles/8 km). However, the effect diminishes over time and in distance and is indistinguishable from zero for larger distances and toward the end of our sample.

In the Sacramento–San Joaquin Delta (Delta), widespread drainage of historical wetlands has led to extensive subsidence and peat carbon losses, as well as high ongoing greenhouse gas (GHG) emissions. Large-scale wetland restoration and conversion to rice fields has the potential to mitigate these effects while conferring flood protection and creating habitat for wetland species. To explore the scale of these potential benefits, this study evaluated the effects of seven Delta-wide land-use scenarios on carbon stocks, land-surface elevation, GHG emissions, and habitat. Peat mapping and data from peat cores indicate that soil carbon stocks have decreased between the early 1800s and 2010s from 288 ± 15 to 145 ± 14 million metric tons (Mt) of carbon (C). If existing land uses continue, the Delta could lose an additional 8.3 Mt C during the coming 40 years, equal to average GHG emissions of 1.2 Mt CO2 equivalents (CO2e) yr-1. Future restoration and rice-farming scenarios indicate that wetland restoration could theoretically halt GHG emissions, converting the Delta from a large GHG source to a weak net source or sink. Across three future scenarios based on existing restoration targets, wetland creation and conversion to rice fields reduced GHG emissions by 0.39 to 0.67 Mt CO2e yr-1, with per-area benefits of 16 to 28 t CO2e per hectare (ha) yr-1. Differences among scenarios in extents of wetland types influenced their relative benefits for different management goals. Tidal restoration and conversion to rice fields enhanced habitat benefits and offered a source of agricultural income, but with reduced GHG mitigation compared with conversion to peat-building wetlands. This highlights the importance of clear objectives when developing land-use plans. A strategic land-management portfolio that includes rice fields and both impounded and tidal wetlands could be designed to provide GHG and subsidence mitigation while offering a diverse suite of benefits for ecosystems and people.

Through a survey and analyses of observational data, we provide systematic evidence that institutional investors value and demand climate risk disclosures. The survey reveals the investors have a strong demand for climate risk disclosures, and many actively engage their portfolio firms for improvements. Empirical analyses of holdings data corroborate this evidence by showing a significantly positive association between climate-conscious institutional ownership and better firm-level climate risk disclosure. We establish further evidence of institutional investors' influence on firms' climate risk disclosures by examining a shock to the climate risk disclosure demand of French institutional investors (French Article 173). Authors have furnished an Internet Appendix , which is available on the Oxford University Press Web site next to the link to the final published paper online. [ABSTRACT FROM AUTHOR]

This study investigates the relationship between responsible leadership and triple bottom line (TBL) performance among food establishment owners and managers in Brgy. New Isabela, Tacurong City, with a focus on Sustainable Development Goals (SDGs) 8 (Decent Work and Economic Growth) and 13 (Climate Action). This study is among the first to explore the role of responsible leadership in TBL performance within the context of local food establishments. The study encompasses 57 respondents, representing a total enumeration of food establishment owners and managers in the area. Employing a quantitative research design with a descriptive-correlational approach, the study utilizes purposive sampling. Adapted and contextualized questionnaires were administered, and data analysis involved Mean, Pearson Moment Correlation, and Multiple Regression Analysis. Findings indicate responsible leadership among food establishment owners and managers in Brgy. New Isabela is characterized by a very high level, notably in stakeholder relations, ethics and values, self-awareness, systems thinking, and change and innovation. TBL performance levels as indicated by the societal, environmental, and economic performance are also assessed as very high. The study reveals a significant relationship between responsible leadership and TBL performance. Additionally, it identifies systems thinking as significantly influencing TBL performance, highlighting its importance in decisionmaking processes. The implications of the study suggest that responsible leadership plays a crucial role in enhancing both economic and environmental performance within food establishments, aligning with SDGs 8 and 13. By emphasizing the influence of systems thinking on TBL performance, the study advocates for strategic decision-making that benefits not only business operations but also contributes positively to the economy and the environment.

It is a perennial challenge for different political organisations, including environmental NGOs (ENGOs), to accommodate diverse social and political groups’ interests, opinions, and experiences. Without sufficient inclusiveness, ENGOs struggle to help create social and political change at a much faster pace, with climate action in Australia being a key example. In this regard, this paper argues that inclusiveness needs to encompass three dimensions, diversity, equity, and procedural justice, which are critical to managing internal tensions, disagreements, and conflicts. Evidence from two different ENGOs, the Australian Conservation Foundation (ACF) and Extinction Rebellion Australia (XR Aus), shows that despite different types of organisational structures and resource availability, there are different challenges and opportunities for the two ENGOs in trying to establish and maintain higher inclusiveness. While diversity remains challenging to both groups, XR Aus’s self-organising and decentralisation have much easier access to decision-making and autonomous participation than ACF. However, it remains to be seen if XR Aus could harass its organising features to establish and maintain a higher level of procedural justice. These findings are relevant not only to issues in climate action problems but also to other collective action problems such as ethnics equality, domestic violence, income disparity, and gun control.

Climate change poses a massive and growing threat to wildlife. Calls are growing for coordinated and collaborative responses to conserve species threatened by climate change, but how this works in practice remains largely unexplored. Focusing on seabirds in North‐West Europe, we carried out 32 semi‐structured stakeholder interviews to (1) explore existing conservation work linked to climate change, (2) identify barriers to work on climate change among conservation actors, and (3) identify key conservation actors and characterize their interactions. Interviewees identified a range of research, policy, and practical conservation work for seabirds related—directly or indirectly—to climate change. They highlighted the importance of general conservation work to facilitate seabird adaptation to climate change, and global mitigation of climate change (e.g., through decarbonization and ecosystem restoration). Interviewees identified several barriers to conservation work explicitly addressing climate change, pertaining to information, leadership, resources, and values/beliefs. We discovered that seabird conservation networks are generally well‐established and harmonious, but not tension‐free. There are also some misunderstandings over actor responsibilities that could lead to bystander effects. We present suggestions to increase the effectiveness and efficiency of seabird conservation in response to climate change. [ABSTRACT FROM AUTHOR]

Flash droughts, characterized by rapid onset and development, present significant challenges to agriculture and climate mitigation strategies. Operational drought monitoring systems, based on precipitation, soil moisture deficits, or temperature anomalies, often fall short in timely detection of these events, underscoring the need for customized identification and monitoring indices that account for the rapidity of flash drought onset. Recognizing this need, this paper introduces a global flash drought inventory from 1990 to 2021 derived using the Soil Moisture Volatility Index (SMVI). Our work expands the application of the SMVI methodology, previously focused on the United States, to a global scale, providing a tool for understanding and predicting these rapidly developing phenomena. The dataset encompasses detailed event characteristics, including onset, duration, and severity, across diverse climate zones. By integrating atmospheric variables through their impact on soil moisture, the inventory offers a platform for analyzing the drivers and impacts of flash droughts, and serves as a large, consistent dataset for use in training and evaluating flash drought prediction models.

Climate change has become a global issue, but no study has examined the discursive construction of resistance to climate change as part of crisis response in the media. To fill this gap, this study employs Wodak's discourse-historical approach to examine 82 news articles collected from China's English-language news media. The analysis reveals three themes used in the construction of a discourse of resistance to climate change: (1) climate change as a global enemy, (2) China as a leading climate change fighter, and (3) other nations as China's allies in the fight. These themes are articulated in the news stories using discursive strategies such as nomination, predication, argumentation, and mitigation. The article sheds light on the language state-run news media uses to project China's image abroad and encourage international collaboration and action in the fight against climate change. It also illustrates how discourse analysis can illuminate the geopolitical and sociocultural dimensions of climate change. [ABSTRACT FROM AUTHOR]

Supersulfated cements (SSCs), as potential green alternatives to Portland cements, are in demand for developing new kinds of precursors instead of blast-furnace slag. A mixture of kaolin, quartz and sodium hydroxide was calcined to prepare SSC by grinding clinkers with lime and gypsum. Preparation factors were investigated and multiple characterisation methods were adopted to explore the calcination and hydration mechanisms. The sodium hydroxide additive was found to reduce the activation temperature of the kaolin and a moderate addition of sodium hydroxide improved the compressive strength of SSC made from calcined kaolin. Quartz added into the kaolin calcined with a moderate amount of sodium hydroxide also promoted the compressive strength. Comprehensive characterisations indicated that the alkali-added calcination of the kaolin generated pozzolanic zeolite and sodium aluminosilicates along with inert nepheline at a calcination temperature ≤950°C. The hydration of SSC pastes tended to produce C(N)–A–S–H/N(C)–A–S–H gels and crystalline ettringite. During sodium hydroxide-added calcination, quartz added into the kaolin hindered the generation of inert nepheline and produced cementitious N–S gels. The research facilitates the utilisation of the massive discharged coal gangues rich in kaolinite and quartz by synthesising SSCs economically. [ABSTRACT FROM AUTHOR]

Social media greatly facilitates people's access to information; however, it can also lead to information overload and exposure to uncomfortable content that may cause individuals to avoid it. As a result, two types of influencing mechanisms emerge: information exposure and information avoidance, which may impact users' behaviors. Currently, there is limited understanding of the simultaneous effects of social media information exposure and avoidance on individuals' behavioral intentions towards climate change mitigation. Using survey data for 1056 Chinese Gen-Z undergraduates and based on the extended theory of planned behavior, this paper utilizes a partial least squares structural equation model to examine the effects of social media information exposure and information avoidance on individual low-carbon behavioral intention. The results show that information exposure on social media has a positive relationship with behavioral attitude, subjective norm, and perceived behavioral control, and then increasing the low-carbon behavioral intention. Information avoidance has a negative association with three factors, respectively, and decreases the low-carbon behavioral intention. Additionally, exposure to social media information has the greatest impact on the subjective norm and the least impact on behavioral attitude; information avoidance has the greatest impact on behavioral attitude, whereas perceived behavioral control is the least affected. Drawing from the results, we propose policy recommendations that facilitate information exposure while addressing avoidance in shaping low-carbon behavioral intentions. Those implications would help reconcile the two opposing effects while promoting public engagement in climate activities. [ABSTRACT FROM AUTHOR]

Transportation electrification aims to mitigate climate change but will also introduce challenges to adaptation planning and management of infrastructure and facilities. Concurrently, these challenges can be amplified by vulnerabilities arising from the growing intense climate and weather events, such as heavy precipitation and tropical cyclones. Given their role in channeling the mobility of residents under environmental shocks, public electric vehicle charging stations (EVCS) need to exhibit resilience, i.e., the ability to withstand, respond to, and recover from disruptions. EVCS service flow can be disturbed not only by physically damaging charging stations but also by impeding the station-user interactions along spatial networks. To our best knowledge, the user-centric resilience of EVCS networks, when confronted with present and anticipated shocks, has not been well studied. We introduce a novel bipartite network of EVCSs and users (BNEU) to conceptualize the resilience of neighborhood charging service flows under environmental shocks using three-level resilience metrics. We then correlate the resilience of BNEU with the physical, socioeconomic, and topological characteristics. Furthermore, we develop a counterfactual analytical framework using a multiagent-based model to simulate users' charging activities in worse-case scenarios of a real-world hurricane, with intensified wind and flood hazards. Through a case study of Hurricane Ian's disturbances on the BNEU in the Tampa Bay area, we find that topologically dispersed subnetworks and stations or user nodes with higher average degree show greater resilience. We also uncover uneven charging opportunities for older adults and low-income populations under disturbances, which could be exacerbated by worse-case hurricane scenarios. The counterfactual analytical framework further informs strategic infrastructure planning for the forward-looking resilience of EVCS network in coastal communities, thus closing the resilience gap in the adaptation of mitigation measures.

Many countries, including Germany have struggled to agree on ambitious climate action, in part because technocratic policy advice failed to adequately consider the social and political consequences. The combination of science and citizen deliberation could enable a new coalition to stimulate policy learning along different climate policy options. The Ariadne Project was a transdisciplinary research project about different policy options for the German Energy Transition. It facilitated an iterative social learning process between researchers and citizens during focus groups, citizen conferences and online deliberations. As such, this case sheds light on a new culture of science–society relations. To assess if and how learning occurred, we ask whether the involved citizens and researchers have changed their understanding of policy options and of each other. We found that citizens were very enthusiastic about the new learning opportunities, and their roles within them. While researchers appreciated the new experience, they also faced challenges. We argue that despite these challenges, there is inherent value in providing spaces for researchers and citizens to interact with and jointly inform policymakers. [ABSTRACT FROM AUTHOR]

The European Green Deal (EGD) represents the most ambitious environmental policy framework in European history, aimed at improving the health and well-being of citizens and future generations through climate action and becoming the first climate-neutral region in the world by 2050. The EC has initiated the European Democracy Action Plan and the European Climate Pact to include the participation of citizens in a meaningful way to help achieve these goals (i.e. not simply a tokenistic gesture or box-ticking exercise). While these efforts to ensure greater citizen participation and deliberation in environmental policy are good first steps, there is still a lack of clarity about what meaningful citizen engagement should look like. This paper will propose that for such efforts to be successful, we need to assess different perspectives in the debate and provide recommendations based on this. This paper provides a systematic review of various approaches within the academic literature on citizen participation and deliberation in environmental policy (ecocentrism, biocentrism, ecomodernism, ecofeminism, environmental pragmatism, environmental citizenship, environmental rights, and environmental justice). Following this, we provide a list of 16 criteria (in five thematic sections) for policymakers, civil society organisations (CSOs), and society, to ensure meaningful citizen participation and deliberation.

Democratic innovations scholars note that deliberation has the potential to counteract populism. However, so far, we do not know what the theoretical foundation would be to expect such an effect, nor do we know to what extent the supposed effect actually materialises empirically. This study adds to the literature by offering a theoretical framework and by testing this framework empirically. Specifically, we examine to what extent citizens with a high degree of populist attitudes became less populist after participating in a deliberative event. We study an actual citizens' assembly on climate mitigation policy in the Netherlands via pre- and post-surveys and carry out an SEM analysis (N = 105). We find that citizens with a higher degree of populist attitudes do become less populist, but find no evidence that this is due to the (perceived quality of the) deliberation. At the same time, the climate skeptics who participated became more populist. [ABSTRACT FROM AUTHOR]

The Miyawaki method, developed by Akira Miyawaki, restores natural forests by planting diverse native species in compact spaces, rapidly creating compact, resilient ecosystems. Initially successful in Japan, its global application bloomed but remains rare in Mediterranean urban areas despite benefits like biodiversity enhancement and climate change mitigation. This method's effectiveness in Mediterranean climates, which face unique challenges like urban heat islands and biodiversity loss, is underexplored in literature and practice. We are leading a project in Italy to identify optimal plant assemblages, addressing the method's documentation gap in urban settings. It explores the potential of Tiny Forests to provide ecosystem services and improve urban liveability against climatic extremes. This note paper details the methodological steps undertaken in this experimental application, offering a tailored approach to test the method's adaptability and impact in Mediterranean urban environments, suggesting a significant opportunity for urban greening and resilience.

Previous research has shown a link between extreme weather events and people's beliefs about climate change and their pro-environmental behaviour. This indicates that people may become more environmentally friendly amid increasing extreme weather events. Still, the influence of experiencing extreme weather events on actual behaviour has rarely been tested with large-scale individual-level data and longitudinal methods. This study links panel data from 35,678 individuals to floods across England and heatwaves across the UK and applies within-person estimators to account for pre-existing differences between affected and unaffected individuals. Results reveal that individuals are more likely to believe in climate change after being affected by a geographically proximate flood or a temporally proximate heatwave. This association is stronger among initially right-leaning partisans and those initially more sceptic about the existence of climate change, thereby indicating attitudinal updating due to experiential learning. However, those exposed to extreme weather events do not change their environmental behaviour such as energy saving, sustainable shopping or mode of transportation. Even among those who are more likely to believe in climate change, people's behaviour does not react to extreme weather events. [ABSTRACT FROM AUTHOR]

Although China's carbon emission trading schemes (CETS) garnered significant attention in the field of climate mitigation, limited data availability has hindered exploration into the impact of CETS on economic inequality at the county level in China. Given its potential to facilitate industrial upgrading and generate employment opportunities, the adoption of CETS holds promise for reducing economic inequality. To address data limitations, we employed a combination of gridded nighttime light data and land use data to estimate China's county-level Dagum Gini coefficient and its components. Subsequently, we applied a difference-in-difference-in-difference method to examine how CETS affected economic inequalities between and within urban and rural areas in China. Our findings reveal that: (1) CETS significantly reduced overall economic inequality in counties with a high proportion of secondary industry output; (2) this reduction primarily occurred within urban and rural areas rather than between them. Further heterogeneity analysis demonstrates that while CETS effectively mitigated economic inequality between urban and rural areas in central and western regions, it did not achieve similar outcomes in the eastern region; (3) service industry development and rural GDP per capita served as important channels through which CETS reduced economic inequality within rural areas. Infrastructure development driven by CETS primarily addressed economic inequality within urban areas rather than rural areas. Key policy insights: It is confirmed that China's CETS made a significant contribution to mitigating economic inequalities within urban and rural areas. This empirical evidence provides new decision-making support for the future promotion of CETS at the county level. It is recommended to propose higher quotas for service industries in rural areas and allocate a portion of revenue from carbon emission trading markets to promote entrepreneurship among rural residents and support upgrades in the rural industrial structure. Considering that the infrastructure development driven by CETS has predominantly addressed economic inequality within urban areas rather than rural areas, it is imperative to allocate a greater proportion of revenue from CETS towards supporting rural infrastructure construction.

Nature-based Solutions (NbS) form a substantial part of cost-efficient climate change mitigation options. However, public financial flows towards NbS have been limited. Among the factors impeding investments in NbS are challenges in reliable remote project identification and comparison. In this article, we demonstrate a technological solution to these challenges. Using cloud-based satellite data processing and the proliferation of open geospatial data, we developed a methodology to map NbS suitability based on a set of biophysical, pedological, hydrological and climatological criteria. To provide a proof of concept, we identify potential project areas for eight types of NbS in Rwanda and Lesotho. Building on these spatially-explicit NbS suitability data layers (accessible at ), we develop marginal abatement cost curves for projects in Rwanda and Lesotho. We thus provide a proof of concept for remote identification and project comparison. These technological developments can help investors, such as multilateral donors or governments, alleviate additionality concerns that are implied by local project selection. Key Policy Insights: Investment in climate change mitigation through Nature-based Solutions (NbS) is limited, in spite of the large, cost-efficient potential for achieving national and global goals. Remote project identification and comparison can help alleviate some of the impediments to international investment in NbS. Such remote identification and comparison of NbS projects is now possible because of breakthroughs in cloud-based satellite data processing technologies and increased availability of geospatial data. We present a proof of concept, establishing marginal abatement cost curves for climate change mitigation through NbS in Rwanda and Lesotho. Coupled with the institutional improvements necessary to create a reliable intergovernmental carbon credit market, these technological developments have the potential to boost international investment in NbS.

The climate vulnerability of Indigenous Peoples is closely related to their marginalization from decision-making processes. Although the engagement of Indigenous Peoples in climate policy is increasingly promoted at the international level, there are still multiple barriers to their meaningful participation at the national level. Through an ethnography of the State, this article analyses how both the State's political orientation, and its interpretations of different stakeholders, influence the participation of Mapuche-Pehuenche communities in two mitigation projects implemented in Lonquimay, Chile, in the southern Andes. This study is based on a review of State policies for Indigenous Peoples, participant observations of the mitigation projects' implementation, and qualitative data collected through 26 semi-structured interviews with key stakeholders. The study uses an ethnographic approach to allow an understanding of how the State is constructed in the face of climate change and of Indigenous Peoples' vulnerability. The State project, which shapes the relationship of the Mapuche with their territory, with the State, and among themselves, is reflected in policy implementation patterns and the existing economic development model. All these relationships influence how officials and the Mapuche interpret and implement climate policy. This article demonstrates that by neglecting these relationships, climate policy risks being less effective in part as it reinforces the exclusion of Indigenous Peoples. While Indigenous Peoples' participation poses significant intercultural challenges, it also yields valuable lessons that can promote processes of institutional transformation that contribute to climate mitigation, such as strengthening local capacities and questioning beliefs that have led to climate change. Key policy insights: Indigenous Peoples' recognition and early participation in climate policy have a transformative potential. Counterproductive patterns of policy implementation in Indigenous Peoples' territories constrain climate policy coherence. To promote the meaningful engagement of Indigenous Peoples in climate policy, states must address long-standing conflicts and underlying factors that produce contextual vulnerability to climate change, while strengthening the intercultural competencies that allow a respectful approach to Indigenous knowledge systems and protocols. Officials must be open to transforming their own knowledge, practices, and values to put climate policy at the service of Indigenous communities. [ABSTRACT FROM AUTHOR]

Biofuels are essential to ensure the energy transition and mitigating of climate change. However, understanding the impact of land use change (LUC) and management practices on soil organic carbon (SOC) stocks is fundamental to ensuring well‐founded policymaking and assessing the sector's carbon footprint. Here, we conducted a meta‐analysis (511 pairwise observations) to obtain Brazil's SOC stock change factors (SOCscf) for LUC and management practices in sugarcane fields. Our results showed that converting native vegetation to sugarcane reduced the SOC stock in all assessed periods. The conversion from annual crops to sugarcane showed a reduction in SOC stock in the first 10 years but with a recovery over time. The conversion of pasture to sugarcane reduced the SOC stock only in the 10–20‐year period and had a neutral effect in other periods evaluated. However, our dataset showed high variability in SOCscf, with many observations indicating an increase in SOC stock, which is related to degraded pastures. We observed that the SOC accumulation rate for each ton of sugarcane straw was affected by the interaction between soil texture and precipitation. Regarding straw management, a low removal rate (< 34%) did not affect the SOC stock, while moderate (34%–66%) and high (> 66%) removal resulted in losses of 5.0% (SOCscf 0.950) and 9.9% (SOCscf 0.901), respectively. Our results also showed that reduced tillage and vinasse application increased SOC stocks by 24.0% (SOCscf 1.24) and 10.0% (SOCscf 1.10) respectively, proving to be good strategies to support C sequestration in sugarcane fields. Finally, we highlight that our results can contribute to the improvement of public policies and also be used in future life cycle assessment (LCA) and modeling studies, as they provide robust data to establishing regional SOCscf induced by LUC and management practices, enhancing the reliability of the C footprint assessment of biofuel production.

Carbon emission accounting is an important basis for global climate governance. Based on the consumption-based accounting (CBA) method, the characteristics of carbon flow between national, regional, and product processes could be more clearly reflected. Therefore, CBA is more conducive to clarifying the attribution of responsibilities between producers and consumers, with the principles of fairness and justice. By accounting for carbon emissions in typical countries from 1990 to 2019, we found that the CBA emissions are higher than the production-based accounting (PBA) emissions in major developed countries, while the results are reversed for developing countries. In the past 30 years, the CBA emissions in targeted developed countries generally have shown a downward trend, while in developing countries, they have shown an upward trend. CBA emissions in China have shown a continuous growth trend from 1990 to 2019, but the pace has slowed down significantly over the last decade. Meanwhile, the embodied carbon intensity of China's exports continues to decline, indicating that China is providing more green and low-carbon products to the world. Taking the PV industry as an example, this study further reveals the contribution of specific product industries to the country's carbon transfer through product carbon footprint analysis.

Reducing energy demand in buildings is one of the critical elements of the current climate change mitigation strategies because buildings account for 40% of all energy-related CO2 emissions worldwide. In developed nations where the functional and construction components of the stock are uniform and where the digital twin of the stock has already been built in desirable standard formats for energy simulation exchange, selecting retrofits that optimize energy for the urban building stock is becoming increasingly popular. However, it is challenging to create a similar schema to arrive at energy-efficient retrofits for developing countries where the building stock is highly diverse, with varying construction and operational philosophies, and where there are no readily accessible data sets of existing stock. This study addresses this gap by developing a decentralized customizable decision support system for community-wide annual net-zero planning that policymakers can use for deciding the most efficient building retrofits for reaching the annual net-zero energy targets. The decision support system is deployed to determine a case-study building community's potential for annual net-zero energy use in Mumbai, India. The results demonstrated that the building community's electrical energy-use intensity, as determined by the decision support system, was 29.51 kW·h/m2, with a deficient percent error of 3% from the actual readings. An intriguing finding from the results is that a community can achieve net-zero electrical energy annually when its buildings combine to exchange energy among themselves, even when certain buildings cannot independently achieve zero-energy building status. One building community was found to be precisely close to self-sufficiency, and the other three produced 20%–40% more electrical energy than needed for self-sufficiency. [ABSTRACT FROM AUTHOR]

Canada's agricultural business risk management (BRM) programs require significant public expenditure, with unclear consequences related to climate change adaptation and mitigation through the adoption of beneficial management practices (BMPs). This study examines the relationship between Canada's current suite of BRM programs and the adoption of practices that mitigate GHG emissions in crop agriculture. We review the impacts of agricultural insurance on climate adaptation and mitigation, identifying impacts on both the intensive and extensive margins of production. We consider five potential program modifications, including: (1) changes in producer insurance premiums in AgriInsurance for the adoption of practices that would decrease the actuarially fair insurance rate if they were properly incorporated in the calculation; (2) dedicated insurance products related to trials of specific BMPs; (3) adjustments to current programs to allow more whole‐farm considerations and intercropping; (4) cross‐compliance measures on AgriInvest tied to environmental education; and (5) reduced insurance coverage for unfavorable environmental practices. While the effects of these potential modifications remain uncertain, they will drive the data collection process necessary to ensure that Canada's BRM programs play an appropriate role in greenhouse‐gas reducing BMP adoption and climate change adaptation and mitigation.

Mangrove wetlands contribute to climate change mitigation through efficient carbon burial, yet microbial methanogenesis offsets these climate benefits. We review the diversity of methanogenic microorganisms in mangrove sediments, present the unrecognized role of bacteria on methanogenesis, and highlight the significance of distinguishing various methanogenic pathways to assess mangrove climate benefits.

Individual low-carbon behavior (LCB) plays an important role in reducing carbon emissions and achieving climate mitigation goals to build a low-carbon society. Based on data collected from college students in Xi'an City, this study proposes a Motivation-Opportunity-Ability (MOA) integrated framework that simultaneously considers eight elements and analyzes their combinatorial effects on the LCB of college students through the fuzzy-set qualitative comparative analysis ( fsQCA) method. The analysis results show that: (1) low-carbon knowledge (LK) is a necessary condition for the implementation of LCB among college students and, along with behavioral intention (BI), plays universal and important roles in LCB implementation. (2) the combination of MOA conditions can be summarized into four different paths affecting LCB implementation among college students: 1) publicity and education (PE)-driven under the motivation-dominant mode; 2) the opportunity-pull mode; 3) enjoyment perception (EP)-driven under the motivation-dominant mode; and 4) the ability-push mode. (3) Each mode represents different characteristics and coupling paths to achieve LCB implementation among college students. This study enriches the literature on LCB and provides potential implications for guiding college students' LCB and improving low-carbon management. [ABSTRACT FROM AUTHOR]

The Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) is an active spaceborne remote sensing system that utilizes photon-counting LiDAR to capture highly detailed information about under-vegetation terrain and forest structure over vast spatial regions. It facilitates the accurate retrieval of terrain elevation and canopy height information, critical for assessing the global carbon budget and understanding the role of forests in climate change mitigation. However, challenges arise from the characteristics of the ICESat-2 photon-counting LiDAR data, such as their linear distribution, extensive spatial coverage, and substantial residual noise. These challenges hinder the performances of the state-of-the-art methods when applied on ICESat-2 data for extracting ground or top of canopy, while they perform well on airborne LiDAR that is featured with planar distribution, small coverage, and high signal-to-noise ratio. Consequently, this study proposes a novel algorithm termed Adaptive Linear Cloth Simulation Filtering (ALCSF), for the automated extraction of ground and top-of-canopy photons from ICESat-2 signal photons. The ALCSF algorithm innovatively introduces a cloth strip model as a reference to accommodate the distribution characteristics of ICESat-2 photons. Additionally, it employs a terrain-adaptive strategy to adjust the rigidity of the cloth strip by utilizing terrain slope information, thus making ALCSF applicable to large-scale areas with significant topographical changes. Furthermore, the proposed ALCSF addresses noise interference by simultaneously considering the movability of particles of the cloth strip model and the photon distribution during iterative adjustments of the cloth strip. The performance of the ALCSF is evaluated by comparing it with the ICESat-2 Land–Vegetation Along-Track Products (ATL08) across twelve datasets that encompass various times of day and scenes. In the results, the ALCSF exhibits notable improvements over ATL08 products, effectively reducing the root mean square error (RMSE) of ground elevation by 21.8% and canopy height by 25.8%, with superior performance in preserving terrain details. This highlights the significance of ALCSF as a valuable tool for enhancing the accuracy of ICESat-2 land and vegetation products, ultimately contributing to the estimation of the global carbon budget in future studies.

This study investigates the potential for mitigating the non-CO 2 climate impact induced by air traffic operations at the network scale. Due to the spatiotemporal dependency of non-CO 2 climate impact, aircraft trajectory planning emerges as an operational strategy to mitigate their corresponding effects. However, trajectory planning without considering the interactions between flights is inadequate when studying the actual climate impact mitigation potential. Indeed, meeting climatically oriented aerial traffic requires a holistic view of different aspects of adopting climate-optimal trajectories. In this study, we aim to assess the network-scale effects of full 4D climate-friendly aircraft trajectories. Different indicators are employed to assess air traffic safety, manageability, cost-efficiency, and the environmental impact of optimized routes. Our findings suggest that while optimized trajectories can potentially reduce climate impact, they introduce significant challenges related to air traffic safety, complexity, and demand, especially in sectors in proximity to climate hotspots. These insights highlight the need to develop an advanced mechanism enabling a safe and efficient air traffic management system with minimal climate impact. • Climate-aware flight planning can reduce the climate impact of non-CO 2 emissions. • 4D trajectory optimization is performed for individual flights. • The effects of climate-optimal trajectories on air traffic performance are assessed. • Climate-optimal routes might increase congestion and complexity, jeopardizing safety.

Public participation in local governance is crucial for effective climate action and for ensuring that policies are designed in a way that respects the rights of communities. Policy developments and choices are shaped by the groups that participate, by the ideas that they hold, and by the institutions that enable and constrain their participation. This paper seeks to understand local climate change governance in Ireland by identifying the environmental interests and the ideas of the groups that participate, and by examining how they engage with institutionalised local policymaking processes and with the organisations that represent the officially recognised views of the country's national environmental movement. An analysis of survey data collected from the groups that are members of one of Ireland's Public Participation Networks shows that a majority of groups are small, rural, voluntary, interested in a wide variety of environmental issues and have a pro-ecological worldview. Most groups follow a pro-institutional advocacy strategy at the local level, while only a minority interact with the national environmental movement, mostly limiting their engagement to the acquisition of information. This paper contributes to the literature that examines how interests, ideas, and institutions shape public participation in local climate politics. [ABSTRACT FROM AUTHOR]

The scale at which New Zealand is currently storing and sequestering blue carbon, and could create additional blue carbon via restoration, has been unclear. Here, we calculate a preliminary estimate for the current extent of three key blue carbon ecosystems (saltmarshes, mangrove forests and seagrass meadows), their carbon stocks and their carbon sequestration rates using the best available data to provide a preliminary estimate of blue carbon in New Zealand. We also use local examples to explore opportunities to create additional blue carbon. Based on the available literature, we estimate the current extent of New Zealand's blue carbon ecosystems to be 76,152 ha, which is 1.0% of the area of terrestrial native forests. Our preliminary estimate of New Zealand's blue carbon stock is 2.66–3.76 Mt of carbon, with a current carbon sequestration rate of 0.12 (0.05–0.26) Mt/CO2/yr, which is equivalent to 0.16% of New Zealand's 2021 gross emissions. Restoration of saltmarshes could enhance their carbon sink capacity, mangrove forests are naturally expanding and seagrass meadow restoration techniques at scale are still in development. Developing a national framework for blue carbon protection, monitoring and restoration is important as part of New Zealand's climate change mitigation and adaptation efforts. [ABSTRACT FROM AUTHOR]

There is growing interest in enhancing soil carbon sequestration (SCS) as a climate mitigation strategy, including neutralizing atmospheric emissions from fossil‐fuel combustion through the development of soil carbon offset markets. Several studies have focused on refining estimates of the magnitude of potential SCS or on developing methods for soil carbon quantification in markets. We call on scientists and policy makers to resist assimilating soils into carbon offset markets due to not only fundamental flaws in the logic of these markets to reach climate neutrality but also environmental justice concerns. Here, we first highlight how carbon offset markets rely on an inappropriate substitution of inert fossil carbon with dynamic stocks of soil carbon. We then note the failure of these markets to account for intersecting anthropogenic perturbations to the carbon cycle, including the soil carbon debt and ongoing agricultural emissions. Next, we invite scientists to consider soil functions beyond productivity and profitability. Finally, we describe and support historical opposition to offset markets by environmental justice advocates. We encourage scientists to consider how their research and communications can promote diverse soil functions and just climate‐change mitigation. [ABSTRACT FROM AUTHOR]
