I don’t know enough abut carbon trading, but I suspect that it is basically a scam. The whole thing is not very sensible. We have this crazy idea that we are setting an example to the world. What we’re doing is trying to make money out of the world by selling them renewable gadgetry and green ideas. It might be worthy from the national interest, but it is moonshine if you think what the Chinese and Indians are doing [in terms of emissions]. The inertia of humans is so huge that you can’t really do anything meaningful.
