Research background: Insufficient global cooperation in carbon pricing against global warming has the risk of global carbon emissions rise because of carbon leakage. The effect of a carbon tax on the present supply of fossil fuels is also valuable in regard to global carbon emissions. Purpose: The purpose of this study is to gain more insights into the effects of carbon leakage along with the green paradox on global carbon emissions by reviewing the relevant literature. Research methodology: We provide the problem linked to carbon leakage and the green paradox in the introduction. Then, the effects of carbon leakage and the green paradox on global carbon emissions are elaborated separately. Finally the mutual effects of carbon leakage and the green paradox are reviewed comprehensively. Results: It is seen that various factors like interest rates, fossil fuel extraction costs, the fossil fuel reserves to be discovered in the future and carbon tax incidence are equally important determinants in regard to global carbon emissions. Novelty: This study provides an insight into the mutual effects of carbon leakage and the green paradox on global carbon emissions by reviewing the primary literature in the field.

Water use is one of the most critical sustainability issues of the mining sector. It is important in each stage of the mining life cycle. The water use of the mine can introduce significant ecological changes. It can compete with the water use of households living in the community and other economic activities in the area. We look at the water use of two large scale mining companies and communities in Didipio, Nueva Viscaya and Taganito, Surigao del Norte. We compare water extraction with various factors such as mineral production, land use, rehabilitation, mine development, and environmental concerns. Based on our initial findings, the rate of water extraction of the two mines is significantly correlated with the level of mine development, rehabilitation and pollution control. In both cases, household consumption plays a minimal role in driving the demand for water.

We provide a comprehensive overview of the current state of environmental governance and policy in Kazakhstan as the country is assumed to have a leading role in Central Asia in terms of green growth and sustainable development. The overview of the environmental and institutional framework in the country reveals that the significant steps towards an improvement of environmental governance have been undertaken.

Consider a situation in which countries anticipate an international environmental agreement (IEA) to be in effect sometime in the future. What is the impact of the future IEA on current emissions after its announcement? We show that the answer to this question is ambiguous. We examine four types of IEAs that aim to reduce pollution stock in the environment. IEA type 1 sets a level of emissions, IEA type 2 and IEA type 3 set a percentage and a uniform cut vis-à-vis the business-as-usual policy respectively. IEA type 4 sets the policy that maximizes future joint benefits of the signatories. We show that all of these agreements reach their goal in the long run, but the intended benefits of these IEAs can potentially be offset by the anticipatory non-cooperative response of the signatories, leading to an environmental degradation in the short run. Which IEA is preferable depends on the targeted level emissions during the phase of cooperation. When this target is above a certain threshold, welfare under IEA type 1 is larger than under IEA type 2 which is larger than under IEA type 3. Moreover, the highest level of welfare that can be attained under IEA type 1 is above the highest level of welfare achieved by any one of the other three IEAs.

Climate change is happening, projected to continue and poses serious challenges also for cities' development. Extreme weather events resulting in hazards such as heat waves, floods and droughts are expected to happen more frequently in many parts of Europe. The United Nations Intergovernmental Panel on Climate Change (IPCC) predicts global temperatures to rise an additional 2-4˚C by the end of this century and graduation of weather extremes. While urban areas will generally experience the same exposures to climate change as surrounding regions, the urban setting can alter these local impacts. The replacement of natural vegetation with artificial surfaces and buildings creates unique microclimates altering temperature, moisture, wind direction and rainfall patterns. Moreover cities forms difficult dynamic systems with high density of people, hub of services and infrastructure so the climate change impacts have and will have potentially serious consequences for human health, livelihoods, and assets and ultimately influence the development of the entire city and its surroundings. However, many city managements are still inactive in this field. It is caused mainly by lack of information, low awareness and knowledge and absence of positive good examples. On the other hand an increasing number of cities around the world have begun to plan for climate change by developing stand-alone climate plans or incorporating climate considerations into existing plans, policies, and projects to become more resilient towards existing and future climate impacts, thereby limiting their magnitude and severity. City of Kosice, Slovakia namely, its largest city district West in cooperation with the research institution Carpathian Development Institute had implemented (as one of the first in Slovakia) the process of climate change adaptation in order to be better prepared and adjust proactively for the heat waves as the critical climate change impact on the city borough residents. The adaptation strategy is built on the principle "low cost quick win" based on assumption that increasing resilience requires not only robust decision making and big investments, but also a strong web of institutional and social relationships that can provide a safety net for vulnerable populations. Through both formal planning activities and concrete measures preparations, city is building their capacity to adapt effectively to existing and future climate impacts, while also experimenting and innovating in policy making and planning. The paper highlights key lessons learned from planning and implementing climate adaptation process as a part of innovative and integrated city development policy.

The powerful typhoon Haiyan that swept across the Philippines is one of the strongest storms ever to make landfall, cut a path of destruction through several central islands, causing scores of people dead. The disaster's full impact is still revealing as the entire country has been caught in a state of shock and desperation. The devastation is really horrific with human tragedy. Responding to the disaster of such magnitude calls for both national and international hands to come forward for the affected people.
