The climate G2: China and the US, compared

China and the US – the ‘G2′ of climate talks – are the world’s biggest greenhouse gas emitters and their commitments about future emissions will be crucial to keeping within the climate change safety range suggested by scientists. The FT has a number of graphics showing how the two countries stack up in terms of their current emissions from energy – and what they would need to do to cut (or curb) these levels adequately. As this first one shows, the two countries dwarf others when it comes to emissions:

A hard road to travel: This graphic shows how the US and China compare on several key emissions sources. US emissions are heavily concentrated in transport, while China’s biggest sources are infrastructure and shipping goods to the US. (Click through for full size graphic and credits.)

Solid colours (US blue, China red) show current electricity generation by power source. White space is the IEA 'business as usual' scenario; pale colours are the IEA forecasts if emissions are cut or curbed.
