Here's the WWF G8 Climate Scorecards
From your link;
Regine Guenther, director of the World Wildlife Fund Climate Change Program in Germany, told reporters in the German capital that G8 leaders should commit to reducing emissions in their countries 40 percent by 2020 and 80 percent by 2050.
And from the WWF scorecard (page 33);
Bush administration proposed an alternative national approach, new target: stop U.S. emission growth by 2025 (2008)
Now I'm not sure that the G8 has much chance of cutting emissions by 40% let alone 80% by the specified target dates. Does that mean 40% reduction over current emissions or 40% over projected emissions per the date specified
, because if those reductions are with respect to today's emissions, I don't see it happening, short of abandoning most if not all coal fired power plants and elimination of most if not all oil based transportations systems. And starting a massive nuclear power plant construction effort. In addition to all the usual green options (wind, solar, biofuels, etceteras).
Or a few billion people die.
Pragmatist on board.
