Differentiated Responsibility Gets G20 Nod Before COP28

The New Delhi Leaders’ Declaration captures the intent of the G20 countries, responsible for 80% of global greenhouse gas emissions, to meet Paris Agreement goals but doesn’t explicitly lay down as to how they would do it.

One of the critical aspects of the declaration, however, is that it underlines the principles of common but differentiated responsibilities (CBDR) in mitigation efforts, and also of different national circumstances that can be useful to the countries of the Global South ahead of the UN Climate Meeting (COP28) in Dubai in November. There is deep trust deficit at climate negotiations particularly on historical responsibility, sharing of the mitigation burden and on the lack of adequate climate finance.
