Global greenhouse gas emission reduction commitments should be more than seven times more ambitious to hope to limit global warming to 1.5 ° C, the most ambitious ceiling in the Paris agreement, worried the UN this Tuesday.

The new promises ahead of the COP26 in Glasgow, which begins on Sunday, “reduce the emissions projections for 2030 by 7.5%, while 30% would be necessary for + 2 ° C and 55% for 1.5 ° C », Specifies the report carried out by the United Nations program for the environment and a team of researchers.

"There has been progress (...) but we are very far from where we should be," said Anne Ohloff, one of the authors of the report.

With the new "nationally determined contributions" filed by 143 countries and the yet to be formalized promises of major economies like China for 2030, the world is now heading towards a warming of at least 2.7 ° C.
