What would be a fair way to share out the blame for climate change? Well, if you look at emissions on a countrywide basis, China looks as much of a culprit as the United States.
That annoys China quite a bit. Their emissions PER PERSON are a sixth of those in America. India's a big polluter too - but per person its emissions are among the lowest in the world.
One area on the map jumps out - the Gulf. Population levels are low but emissions are huge because of all that oil and gas.
People's lifestyles are also a problem. In the programme tonight, our environment analyst Roger Harrabin went to the Emirates and dropped in on Mohsen and Rania Saad and their four year old, hosepipe-wielding daughter Clara. They're one of five families around the globe who have been telling the BBC about their carbon lives.
