Environment ministers from G20 nations gathered in the southern Indian city of Chennai for a one-day conference, in a race against time to reach a last-minute consensus to redress the global climate crisis.

Environment ministers from G20 nations meet in India on Friday in a race against time to reach a last-minute consensus to redress the global climate crisis.

But no major breakthrough is expected as delegations were stuck on climate change adaption finance, mitigation, and peaking emissions by 2025 in hectic negotiations until late Thursday.

Any agreements reached at the one-day conference in Chennai will be signed by the leaders of G20 nations, which constitute more than 80 percent of the global GDP.

The meeting comes only days after the group's energy ministers were criticised for failing to agree on a roadmap to cut fossil fuels from the global energy mix.

It was seen as a blow to mitigation efforts even as climate experts blame record global temperatures for triggering floods, storms and heatwaves.

Some major oil producers, such as Russia and Saudi Arabia, were blamed for the lack of progress.
