A recent article by Robiou du Pont et al. suggests that wealthier countries (for example, the members of the EU) have made more ‘equitable’ contributions to the Paris goals than poorer countries (such as India and China), with most other developing countries somewhere in between. These results are counter-intuitive, given that developed countries have the majority of the responsibility for the atmospheric build-up of Greenhouse Gases (GHGs) and the majority of the financial wherewithal to help solve the climate problem, yet their Paris pledges amount to fewer tons of mitigated emissions than developing countries. This correspondence presents a response to du Pont et. al and points out the biases towards wealthier nations in the approach and methodology adopted.
