Energy and environment ministers from the Group of 20 rich nations have failed to agree on the wording of key climate change commitments in their final communique, Italy¡¯s Ecological Transition Minister Roberto Cingolani said on Friday.

The G20 meeting was seen as a decisive step ahead of United Nations climate talks, known as COP26, which take place in 100 days¡¯ time in Glasgow, Scotland, in November.

The failure to agree to common language ahead of that gathering is likely to be seen as a setback to hopes of securing a meaningful accord in Scotland.
