Remember Copenhagen? China was blamed by many for the failure of the summit. It is also the largest emitter of CO2 (not per capita though). Now it is also the leader in renewable energy investment. This is not a widely known fact, and not publicised widely. The BBC has the story here.
China is still a developing country under the rules of the Kyoto protocol, the largest emitter of CO2 and now the leader on renewables. A truly bizzare situtation. What follows for climate policy? Perhaps that developed countries will have to play catch up?
