India’s developmental challenges are significant and need to be overcome urgently, especially in the era of climate change. The impacts of climate change, both ongoing and the potential impacts in the future, have been compounded further by climate inaction by developed countries. This brief outlines a potential strategy for India to ensure climate justice and equity in global climate action. Based on data, this brief argues that India must strongly lobby for cumulative emissions and the total global carbon budget to be the basis for determining the adequacy and ambition of climate action. A fair share of the carbon space is well in line with the principles of equity and climate justice enshrined in the UNFCCC and is also in keeping with the results of climate science.
