G20 pledge climate action but make few commitments

The leaders of the world's richest economies have agreed to pursue efforts to limit global warming with "meaningful and effective actions".

But the agreement from the G20 summit in Rome made few concrete commitments, disappointing activists.

Host nation Italy had hoped that firm targets would be set before the COP26 summit in Glasgow, which has now begun.

UK PM Boris Johnson, who is hosting COP26 said leaders' promises without action were "starting to sound hollow".

"These commitments... are drops in a rapidly warming ocean," Mr Johnson said.

The G20 group, made up of 19 countries and the European Union, accounts for 80% of the world's emissions.
