The CEOs of 100 large multinational corporations — including companies from carbon-intense industries — have signed a World Economic Forum statement [PDF] that calls on the G8 to create a strategy to cut global greenhouse-gas emissions by at least 50 percent by 2050. The G8 will be meeting in Japan next month, and Japanese Prime Minister Yasuo Fukuda will be pushing hard for an agreement on climate change.

Notable signatories to the statement: Airbus, British Airways, BP, Duke Energy, DuPont, Electricite de France, Entergy, E.ON, Michelin, Petrobras, Renault, Rolls-Royce, and Shell.

Are pigs flying? Not quite.

The companies see money to be made, of course:
