Forests play a crucial role in fighting climate change by acting as carbon vacuum cleaners, absorbing and storing carbon dioxide (CO2) emissions. Forest edges, which are areas where forests meet grasslands or roads, can store more carbon than the forest interior due to increased sunlight and warmth. Forest edges are becoming more prevalent due to forest fragmentation caused by human activities. Protecting small forest patches and planting new forests, even small ones, is essential in maximizing carbon storage and combating climate change. [Extracted from the article]

The rising level of atmospheric carbon dioxide ( C O 2 ) gas is a matter of concern due to its impact on global climate change. The accomplishment of the goal of climate change mitigation requires a reduction in the C O 2 concentration in near future. The forest management programs offer an avenue to regulate atmospheric C O 2 levels. This paper presents a four-dimensional nonlinear mathematical model to study the impact of forest management policies on the mitigation of atmospheric C O 2 concentrations. It is assumed that forest management programs are applied according to the difference of forest biomass density from its carrying capacity. The forest management programs are assumed to work twofold: first, they increase the forest biomass and secondly they reduce the deforestation rate. Model analysis shows that the atmospheric level of C O 2 can be effectively curtailed by increasing the implementation rate of forest management options and their efficacy. It is found that as the deforestation rate coefficient exceeds a critical value, loss of stability of the interior equilibrium state occurs and sustained oscillations arise about interior equilibrium through Hopf-bifurcation. The stability and direction of bifurcating periodic solutions are discussed using center manifold theory. Further, it is observed that the amplitude of periodic oscillation dampens as the maximum efficacy of forest management programs to reduce the deforestation rate increases and above a critical value of the maximum efficacy of forest management programs, the periodic oscillations die out and the interior equilibrium becomes stable. The strategies for the optimal control of C O 2 concentration while minimizing the execution cost of forest management programs are also investigated using the optimal control theory. The theoretical results are demonstrated via numerical simulations. [ABSTRACT FROM AUTHOR]

The International Panel on Climate Change (IPCC) recommended more stringent climate mitigation strategies compared to the updated nationally determined contributions (NDC) presented by nations at COP27 to keep global warming temperatures below 2 °C. Given the unique geographical, political, and socioeconomic factors in different regions, it is imperative to evaluate diverse mitigation scenarios required to achieve global climate objectives. This study focuses on the Latin America and Caribbean region due to its vulnerability to global climate adversities and deteriorating climate conditions, notwithstanding its minor contribution to global emissions. Despite facing distinct climate changes, Latin America remains significantly understudied in the broader context of global climate research. The deployment of negative emission technology (NET) is crucial for achieving the end-of-century global climate goal of limiting global mean temperature to 1.5 °C and realizing regional net-zero greenhouse gas (GHG) emission targets. Most countries in Latin America have established such targets for 2050. Among various NETs, Direct Air Carbon Capture and Storage (DACCS) has recently gained research interests. This study examines the strategic implementation of NETs across the five socio-economic pathways (SSPs) to provide a comprehensive understanding of the uncertainties in regional mitigation actions and impacts on the intricate climate-energy-land-food-water nexus. In the scenario where emissions decrease by 56 % by 2030 compared to 2020 levels (NDC-56 %) on a net-zero trajectory, energy consumption under DACCS deployment is 13.1–36.2 % higher than without DACCS (between 2040 and 2100, across all SSPs). The energy demands of DACCS, especially in the aggressive NDC-56 % scenario place significant strain on energy resources, which is offset by fossil fuels. Under a globally co-ordinated climate policy and co-deployment of DACCS and Bioenergy with Carbon Capture and Storage (BECCS), the NDC-56 % scenario restricts global warming temperatures to 1.81–1.96 °C by 2100. • IAM analysis is used in assessing scenarios of net-zero goal of Latin America. • The deployment of DACCS under aggressive decarbonization is analysed. • The deployment of DACCS reduces the demand on BECCS requirements. • DACCS deployment will reach 88 MtCO 2 /year in the NDC-SSP1 scenario by 2100.

Climate and agriculture are intensely interrelated global processes and therefore a change in climate affects agricultural production. One such change is global warming which is projected to have significant impacts on environment affecting agriculture, including higher carbon dioxide emission, rise in atmospheric temperature, higher glacial run-off, changed precipitation and the interaction of these elements. These conditions determine the carrying capacity of the biosphere to produce enough food for the human population and domesticated animals. The present paper might help to anticipate and adapt farming to maximize agricultural production. [ABSTRACT FROM AUTHOR]

Tourism needs to reduce emissions in line with other economic sectors, if the international community's objective of staying global warming at 1.5°-2.0 °C is to be achieved. This will require the industry to half emissions to 2030, and to reach net-zero by mid-century. Mitigation requires consideration of four dimensions, the Scales, Scopes, Stakeholders and Strategies of carbon management. The paper provides a systematic review of these dimensions and their interrelationships, with a focus on emission inventory comprehensiveness; allocation principles at different scales; clearly defined responsibilities for decarbonization; and the identification of significant mitigation strategies. The paper concludes that without mitigation efforts, tourism will deplete 40% of the world's remaining carbon budget to 1.5 °C. Yet, the most powerful decarbonization measures face major corporate, political and technical barriers. Without worldwide policy efforts at the national scale to manage the sector's emissions, tourism will turn into one of the major drivers of climate change. [ABSTRACT FROM AUTHOR]

The European Union relies largely on bioenergy to achieve its climate and energy targets for 2020 and beyond. We assess, using Attributional Life Cycle Assessment (A-LCA), the climate change mitigation potential of three bioenergy power plants fuelled by residual biomass compared to a fossil system based on the European power generation mix. We study forest residues, cereal straws and cattle slurry. Our A-LCA methodology includes: i) supply chains and biogenic-CO 2 flows; ii) explicit treatment of time of emissions; iii) instantaneous and time-integrated climate metrics. Power generation from cereal straws and cattle slurry can provide significant global warming mitigation by 2100 compared to current European electricity mix in all of the conditions considered. The mitigation potential of forest residues depends on the decay rate considered. Power generation from forest logging residues is an effective mitigation solution compared to the current EU mix only in conditions of decay rates above 5.2% a −1 . Even with faster-decomposing feedstocks, bioenergy temporarily causes a STR(i) and STR(c) higher than the fossil system. The mitigation potential of bioenergy technologies is overestimated when biogenic-CO 2 flows are excluded. Results based solely on supply-chain emissions can only be interpreted as an estimation of the long-term (>100 years) mitigation potential of bioenergy systems interrupted at the end of the lifetime of the plant and whose carbon stock is allowed to accumulate back. Strategies for bioenergy deployment should take into account possible increases in global warming rate and possible temporary increases in temperature anomaly as well as of cumulative radiative forcing.

All sectors face decarbonization for a 2 °C temperature increase to be avoided. Nevertheless, meaningful policy measures that address rising CO2from international aviation and shipping remain woefully inadequate. Treated with a similar approach within the United Nations Framework Convention on Climate Change (UNFCCC), they are often debated as if facing comparable challenges, and even influence each others’ mitigation policies. Yet their strengths and weaknesses have important distinctions. This article sheds light on these differences so that they can be built upon to improve the quality of debate and ensuing policy development. The article quantifies ‘2 °C’ pathways for these sectors, highlighting the need for mitigation measures to be urgently accelerated. It reviews recent developments, drawing attention to one example where a change in aviation mitigation policy had a direct impact on measures to cut CO2from shipping. Finally, the article contrasts opportunities and barriers towards mitigation. The article concludes that there is a portfolio of opportunities for short- to medium-term decarbonization for shipping, but its complexity is its greatest barrier to change. In contrast, the more simply structured aviation sector is pinning too much hope on emissions trading to deliver CO2cuts in line with 2 °C. Instead, the solution remains controversial and unpopular – avoiding 2 °C requires demand management. Policy relevance The governance arrangements around the CO2produced by international aviation and shipping are different from other sectors because their emissions are released in international airspace and waters. Instead, through the Kyoto Protocol, the International Civil Aviation Authority (ICAO) and the International Maritime Organization (IMO) were charged with developing policies towards mitigating their emissions. Slow progress to date, coupled with strong connections with rapidly growing economies, has led to the CO2from international transport growing at a higher rate than the average rate from all other sectors. This article considers this rapid growth, and the potential for future CO2growth in the context of avoiding a 2 °C temperature rise above pre-industrial levels. It explores similarities and differences between these two sectors, highlighting that a reliance on global market-based measures to deliver required CO2cuts will likely leave both at odds with the overarching climate goal.

Global warming mitigation is used as a key to devise built environment strategies and sustainable policies in developed countries that aim to reduce the rate of carbon emissions. The goal of this research is to mitigate global warming from building construction by suggesting an alternative building scheme for Malaysia. A problem related to the building industry is releasing carbon dioxide emission. Use of timber for construction has less impact on the environment due to less carbon dioxide emissions, thus making wood the best material for wall construction. However, as the Malaysian climate is hot and humid, wood encounters many defects and deteriorates. Presently, most buildings in Malaysia are built from other materials such as concrete or brick. In the last 40 years, wood materials in building schemes in Malaysia have dropped from 60% to almost 5%. This research proposed a new approach to minimize the effect of CO 2 emission for buildings as well as to improve their structural stability for a longer lifespan because these would encourage the Malaysian construction industry to use wood components in their building schemes. In this study, SIMAPRO Software was used to assess CO 2 emissions caused by seven different types of building schemes in wall constructions. The results from a simulation of three time frames of twenty, one hundred and five hundred years showed that timber scheme is the best choice for construction. To promote the use of timber, a new building scheme that would solve the problem of timber wood structure in Malaysia were proposed. The alternative building scheme has combined precast concrete and timber (H8) to improve the timber scheme deficiency while releasing less CO 2 emissions compared to other systems. Therefore (H8) could replace current building schemes. This research can facilitate decision-maker to choose the most flexible scheme for Malaysian housing. Thus, this system could be positively and widely used in the Malaysian construction industry. [ABSTRACT FROM AUTHOR]

Recent downward revisions in the climate response to rising CO
2 levels, and opportunities for reducing non-CO2 climate warming, have both been cited as evidence that the case for reducing CO2 emissions is less urgent than previously thought. Evaluating the impact of delay is complicated by the fact that CO2 emissions accumulate over time, so what happens after they peak is as relevant for long-term warming as the size and timing of the peak itself. Previous discussions have focused on how the rate of reduction required to meet any given temperature target rises asymptotically the later the emissions peak. Here we focus on a complementary question: how fast is peak CO2 -induced warming increasing while mitigation is delayed, assuming no increase in rates of reduction after the emissions peak? We show that this peak-committed warming is increasing at the same rate as cumulative CO2 emissions, about 2% per year, much faster than observed warming, independent of the climate response.

Abstract: Countries are implementing CO
2 emission reduction targets in order to meet a globally agreed global warming limit of +2°C. However, it was hypothesised that these national reduction targets are not translated to regional or state level planning, and are not considered through Strategic Environmental Assessment (SEA) in order to meet emission reduction obligations falling on the transport, energy, housing, agriculture, and forestry sectors. SEAs of land use plans in the German state of Saxony, and the English region of the East of England were examined for their consideration of climate change impacts based on a set of criteria drawn from the literature. It was found that SEAs in both cases failed to consider climate change impacts at scales larger than the boundary of the spatial plan, and that CO2 reduction targets were not considered. This suggests a need for more clarity in the legal obligations for climate change consideration within the text of the SEA Directive, a requirement for monitoring of carbon emissions, a need for methodological guidance to devolve global climate change targets down to regional and local levels, and a need for guidance on properly implementing climate change protection in SEA.

Problem: In the absence of U.S. federal action to address the problem of climate change, a diverse array of nonfederal policy entrepreneurs and climate action planners has produced an impressive body of plans and policies to fight climate change at the regional, state, and local levels. Their actions are highly laudable, but have they actually reduced greenhouse gas (GHG) emissions? Purpose: This article evaluates the work of a group of innovative state-level policy entrepreneurs whose actions were chronicled by Barry Rabe, and a set of 29 state climate action plans systematically analyzed by Stephen Wheeler. It compares states with and without climate policy entrepreneurs and states with and without climate action plans, asks if either plans or entrepreneurs have been successful in reducing CO2 emissions, and identifies the elements within plans that are associated with the greatest reductions. Methods: The analysis uses multiple regression models to explain changes in per capita CO2 emissions attributable to residential, commercial, transportation, and total nonindustrial end users from 1990 to 2007. A package of control variables accounts for political, social, climatic, economic, and urban form factors, while policy variables isolate the effects of climate policy entrepreneurs, climate action planners, and specific policy recommendations within climate action plans. Results and conclusions: State-level climate actions reduce GHG emissions by a measurable but modest amount: about one half metric ton per person per year. This represents 2-3% of the average American's 24-ton annual total GHG emissions. The reduction is small in comparison to the magnitude of the problem, but a substantial tax increase or population shift away from sprawling areas would be necessary to achieve the same reduction. Specific policies I find to be associated with lower emissions include: building efficiency in both residential and commercial sectors, Leadership in Energy and Environmental Design (LEED) policies in the commercial sector, and California's vehicle efficiency standards in the transportation sector. Takeaway for practice: It is encouraging that we can already identify emission reductions related to state climate action. However, the observed reductions remain small com-pared to the scope of the problem. These findings should persuade states without plans to begin the planning process while encouraging states with plans to encourage more entrepreneurship aimed at developing a second generation of policy options for stabilizing our planet's climate with or without federal action. Research support: None. [ABSTRACT FROM AUTHOR]

Climate change mitigation poses significant challenges for South Africa and its energy development, historically highly energy intensive. At the same time, the country faces a host of daunting development challenges, exacerbated by the legacy of apartheid. Examining both challenges, this paper considers how alternative conceptions of a development path can be achieved. In the short term, energy efficiency provides large potential for mitigation - and energy savings at the same time. Changing South Africa's fuel mix, dependent to three-quarters on coal, is at least a medium-term challenge. The minerals-energy complex is so central to the economy that it is likely to take decades to change dramatically. The most transformative change is to an alteration in economic structure, likely to take long to achieve. The article examines specific policy instruments that might be implemented to achieve such a transformation. A transition to a low-carbon economy will require a paradigm shift in industrial policy. It will require considered provision for sectors sensitive to changes in energy prices. Building up new, climate-friendly industries will be needed to sustain employment and investment. To enable a just transition, provision will have to be made for emissions-intensive sectors, if they are to be phased out over time. South African government has adopted a vision, strategic direction and framework for climate policy. Policymakers have begun to understand that the future will be carbon constrained and that South Africa's emission will have to stop growing, stabilize and decline before mid-century. The challenge of climate change is a long-term challenge, requiring immediate action. This article examines actions at near-, medium- and long-term timescales. Its focus is on the most transformative change, that of seeking to shift development paths. [ABSTRACT FROM AUTHOR]
