US envoy: Climate change policies 'not enough'

Policies introduced by China, India and the US aimed at reducing the effects of climate change do not go far enough, according to a US envoy at an environmental summit in London, Bloomberg reported. Todd Stern, the US delegate at the 17-nation climate change conference, said that while new environmental policies were a step in the right direction, they would not be enough to limit global temperature increases to 2 degrees Celsius. "Where they are right now is certainly not enough," Stern said, claiming that China and India were among those who needed to step up the pace of action.
