India has submitted its 2030 climate action plan to the United Nations in advance of December’s Paris climate talks.

The nation becomes the 148th country and the last major world economy to declare its plan, which includes a pledge to expand its renewable power capacity to 40 per cent of its energy mix by 2030.

The plan also promises to cut greenhouse gas emissions by 35 per cent by 2030 compared to 2005 levels, up from a previous pledge to cut emissions by 25 per cent by 2020.

In the plan, called the Intended Nationally Determined Contribution (INDC), India says it aims to introduce more efficient and cleaner technologies in its thermal generation sector; promote energy efficiency in industry, transport, buildings and appliances; and develop a climate-resilient infrastructure.

The nation said it aims to install 175 GW of solar, wind and biomass power capacity by 2022, and 63 GW of nuclear power capacity by 2032. It plans to “aggressively pursue” new hydropower projects although it did not list a specific target, and to establish a carbon sink of 2.3bn to 3bn tonnes through planting more trees.

Commentators have noted that the plan could cost up to $2.5tn to implement. In its plan, India called on the world’s rich nations to assist it in achieving its goals.
