The aim of this paper is to test whether income inequality contributes to environmental degradation in China and India, where both countries are giving a great concern about the implications of their unsustainable energy consumption to the environment not only to themselves but also to the global environmental sustainability. By applying the bounds test approach to cointegration we found in both countries a long-run but not a statistically significant relationship between income inequality and CO 2 emissions both in the long-run and in the short-run. The robustness of our cointegration results is also ascertained by using three different long-run tests. Furthermore, applying the variance decomposition analysis to examine the dynamic causal relationship between the Gini coefficient of income distribution and CO 2 emissions, we found that income inequality was the least important factor in determining CO 2 emissions and that there was no causality running in any direction between CO 2 emissions and income inequality in both countries. Still income and energy consumption are the major determinants of CO 2 emissions in both countries. Nevertheless, even though the evidence is not statistically significant, in the case of China it indicates that reducing income inequality can have a positive impact on environmental quality, while in India redistributing income to improve environmental degradation may not be effective.

This article offers three instruments to effectively mitigate climate change in the context of the Conference of the Parties (COP)26 and beyond. The first is the interaction between the climate and trade regimes. To that end, this article presents a thought-provoking premise - that mega-regional trade agreements (RTAs) can take a significant role in climate change mitigation. It argues that mega-RTAs can go further to galvanize climate change mitigation, in particular in the energy sector. The energy sector is the largest contributor of greenhouse gas (GHG) emissions, with the majority of energy consumption being supplied by fossil fuels such as coal, natural gas, and oil. As such, there are two main arguments made herein. First, mega-RTAs, as tangible indications of what is acceptable to major economies, are the impetus to influencing greater coherence on energy efficiency standards. This contributes to climate action by creating, even if to some extent, the harmonization of an otherwise fragmented status of energy governance. Second, mega-RTAs can create substantive provisions that redirect support from fossil fuels to renewable energy. This is the very essence of the energy transition. It is envisaged that these two roles conveyed effectively through mega-RTAs can substantially support the energy transition and amounts to action that mitigates climate change and promotes sustainable energy. The second instrument to effectively mitigate climate change is the role of two major Asian countries that are key in the fight against climate change, namely India and China. Both countries can play a major role in effectively mitigating climate change in the future, following the agreement at COP26 that coal must be phased down. Lastly, the third instrument is visualizing what a decarbonized future would look like. Two of many possible pathways for decarbonization are examined: clean-energy technologies and shale gas as a bridge to sustainability. The article argues that these pathways can be meaningful for effective climate action and are in alignment with the Glasgow Climate Pact. [ABSTRACT FROM AUTHOR]
