A comparative analysis of worldwide climate policies, taking the European Green Deal as a yardstick, shows only a limited degree of convergence. While the European Union (EU), the United States, Japan and People’s Republic of China (PRC) have set between 2050 and 2060 as a time limit to achieve climate neutrality, global practices aiming to reduce greenhouse gas emissions and adapt to their implications are still largely ineffective and unco-ordinated. Despite significant efforts, rather than displaying a harmonious framework, climate policies spanning the EU, the United States, PRC, Latin America, Middle East, Asia-Pacific, and Africa appear as a fragmented patchwork. This is true not only from the standpoint of external relations, comparing and contrasting the policy of different States and sovereign entities, but also internally, owing to such divisions as polycentric regulatory powers in federal States; asymmetric interests in geopolitical blocs such as the East, West, and Middle East; and different degrees of social cohesion in developing countries.
