The Japanese government and U.S. government decided to cooperate on global warming and other environmental problems. According this joint document(tentantively titled "energy security", they will be engaged in innovation technologies, for example the retention technology to contain CO2 in the ground. The their aim is making it easier for U.S. to join Post-Kyoto activities. U.S.'s participation will be important because he is the world's largest producer of greenhouse gases.
I wonder why U.S. starts to think about environmental problems. I think U.S. should do earlier. Though this cooperation is great and they rather think about these problems than war. I don't agree with their military convention. But I want to support the cooperation like the article.
