Environmental groups had a different take.

Greenpeace climate expert Tobias Muenchmeyer: “There is no breakthrough, and there is no compromise. There are results now on the table which show that G8 has, the group of the eight biggest economies has, failed to live up to responsibilities when it comes to climate change. There is no consensus on reductions on 50 percent CO2 emissions by 2050, since the U.S. is not willing to accept this.”
