India, one of the world's largest greenhouse gas emitters, has ratified the Paris global climate agreement.
Under the deal, India has committed to ensuring that at least 40% of its electricity will be generated from non-fossil sources by 2030.
CO2 emissions are believed to be the driving force behind climate change.
Last December in Paris, countries agreed to cut emissions in a bid to keep the global average rise in temperatures below 2C.
The Paris deal is the world's first comprehensive climate agreement.
The US and China - together responsible for 40% of the world's carbon emissions - both formally joined the Paris global climate agreement earlier this month.
India accounts for about 4.5% of global greenhouse gas emissions, and became the 62nd country to ratify the agreement.
The European Union is expected to do so in the near future, taking approvals past the 55% of emissions threshold.
