Global climate change due to increasing CO2 emissions threatens the development and survival of many countries, especially those on the coast. Intentional government spending by sectors can lower CO2 emissions to help these countries in sustainable development. Meanwhile, governance has some importance in enabling governments to achieve their economic development goals. Does governance affect the public spending - CO2 emissions nexus in developing economies? The paper seeks answers by employing the system GMM Arellano-Bond estimators to assess the impact of public spending, governance/institutional quality, and their interaction on CO2 emissions for a sample of 109 developing economies between 2002 and 2021. The results seem counter-intuitive that public spending reduces and governance increases CO2 emissions, while their interaction lowers them. Furthermore, private investment and economic growth promote CO2 emissions, while trade openness decreases them. The findings in this paper provide some policy lessons for governments of developing economies to protect environment. [ABSTRACT FROM AUTHOR]

Abstract Cities do play significant roles in tackling global environmental changes. Decoupling economic growth from environmental pressures is critical for global sustainable development, however, few studies pay attention to the decoupling analysis at city level. This paper conducts a comparative study of the decoupling performance of economic output from CO 2 emissions between Beijing and Shanghai, the top two cities in China. In this paper, the decoupling trends and the decoupling effects are explored from a sectoral perspective, by combining the Tapio decoupling elasticity and the logarithmic mean Divisia index (LMDI) model. The results show that Beijing and Shanghai both experienced weak decoupling in construction, expansive negative decoupling in transport, expansive coupling in trade, and weak decoupling in others over the period 2000–2015. Moreover, agriculture appeared strong decoupling in Beijing, and recessive decoupling in Shanghai; industry showed strong decoupling in Beijing, and weak decoupling in Shanghai. The decoupling effects showed different magnitudes and patterns in industrial sectors between Beijing and Shanghai. Overall, per-capita GDP and population growth inhibited the decoupling, while energy intensity, industrial share, energy mix accelerated the decoupling process. Highlights • The decoupling of sectoral economic output from carbon emissions in Beijing and Shanghai are investigated. • Beijing's industry enjoyed better decoupling performance than Shanghai's industry. • Transport should be put more emphasis in further decoupling efforts. • Energy intensity is crucial effect accelerating the decoupling process.

The assumption of the realist theory that survival and self-interest without more are the ultimate goal of each state in international politics and the liberals' viewpoint that international cooperation is in the best interest of a state are as valid and controversial in climate change discourse. Hence, the political choice which Africa should make in the light of increasing adverse effects of climate change, and in particular, amidst the tension of these two theories remains problematic and confounding. Generally, the negative effects of climate change will be prominent in areas including food production, health, water, and infrastructure in Africa. Yet, for long, activities underlying the causation of climate change have thrived in the neo-liberal notion of economic self-determination contrived by the North and remarkable for its historic carbon prints world over. Solutions to climate change in the form of carbon trading and carbon tax have been informed by a similar worldview. Following this path connotes that states in Africa must avoid carbon-based activities which are at the heart of economic development critical to peoples' social economic well-being. It also means that states in Africa should embrace carbon friendly activities, the technology of which is largely at the domain of the North. The merit of the above direction in the quest of economic development in Africa is disputed. This paper aims not only at exploring how adequately political realism can shape the option of Africa in navigating this controversy, it also discusses the prospects and challenges of a possible 'carbon free economy' in Africa.

Abstract: India is facing great challenges in its economic development due to the impact on climate change. Energy is the important driver of economy. At present Indian energy sector is dominated by fossil fuel. Due to international pressure for green house gas reduction in atmosphere there is a need of clean energy supply for energy security and sustainable development. The nuclear energy is a sustainable solution in this context to overcome the environmental problem due to fossil fuel electricity generation. This paper examines the implications of penetration of nuclear energy in Indian power sector. Four scenarios, including base case scenario, have been developed using MARKAL energy modeling software for Indian power sector. The least-cost solution of energy mix has been measured. The result shows that more than 50% of the electricity market will be captured by nuclear energy in the year 2045. This ambitious goal can be expected to be achieved due to Indo-US nuclear deal. The advanced nuclear energy with conservation potential scenario shows that huge amounts of CO2 can be reduced in the year 2045 with respect to the business as usual scenario. [ABSTRACT FROM AUTHOR]

China's reform/opening process has been exceptionally successful at generating lasting economic growth and in lifting millions of people out of absolute poverty. However, this success came at a significant price. Environmental degeneration represents one critical issue. Other serious topics include an increasing income and development gap between and within provinces, and between rural and urban areas. A proposed shift towards a low-carbon economy seems to provide an answer in addressing this complex environmental–development challenge. However, decisions on a future course of action are not made in a political, economic or social vacuum, instead decisions are made in the context of a particular structural environment, which restricts the options available for actors. Applying a structure–agency approach will help to identify and highlight the existing structural challenges inherent within China's development strategy. [ABSTRACT FROM PUBLISHER]
