Leaders of nearly 200 major companies around the world have called for tougher action on climate change.
But the window to keep global warming below 2C has “almost closed”, it warns.
Companies signing up include UK retailer Tesco, energy provider EDF, electronics company Philips, chemicals giant Unilever, eBay and Rolls-Royce.
The corporate leaders communique says that the scientific and economic case for tackling climate change remains clear.
“If we do not act, climate change risks seriously undermining future global prosperity and inflicting significant social, economic and environmental costs on the world,” it reads.
