G20 fails to reach agreement on cutting fossil fuels

The G20 major economies meeting in India have failed to reach consensus on phasing down fossil fuels following objections by some producer countries.

Scientists and campaigners are exasperated by international bodies' foot-dragging on action to curb global warming even as extreme weather from China to the United States underlines the climate change facing the world.

G20 energy officials had been due to issue a joint communique at the end of their four-day meeting in Bambolin, a town in the Indian coastal state of Goa.

But it was dropped due to disagreements including the intended tripling of renewable energy capacities by 2030.

Sections urging developed countries to deliver on the goal of jointly mobilising $US100 billion ($A149 billion) per year for climate action in developing economies from 2020-2025, and description of the war in Ukraine, also eluded consensus.

Fossil fuel use became a lightning rod in day-long discussions but officials failed to reach consensus over curbing "unabated" use, two sources familiar with the matter said.

A draft late on Friday reviewed by Reuters read: "The importance of making efforts towards phase down of unabated fossil fuels, in line with different national circumstances, was emphasised".

However, instead of a joint communique, a chair statement was released on Saturday evening, noting that "Others had different views on the matter that abatement and removal technologies will address such concerns".

India's Power Minister RK Singh, in a press briefing after the conference ended, said some countries wanted to use carbon dioxide capture instead of a phase down of fossil fuels.

He did not name the countries.

However, major fossil fuel producers Saudi Arabia, Russia, China, South Africa and Indonesia were all known to oppose the goal of tripling renewable energy capacity this decade.
