If you understood the principle of carbon-credit market, you would not say that. The idea is exactly that: buy credits, and the "polluting responsability" will be shifted to the seller.
I'm not stupid, cikomyr, but I thank you for condescending to me all the same.
Is it wrong to pollute the environment, or not? If it is wrong, it makes no difference whether someone has purchased a billion carbon credits, or none; the damage has been done. What you are suggesting is that the wealthy and the privileged have a right to live as wasteful gluttons while the poor need to live like crap because we can't afford the carbon credits. Ironic, considering your position as "championing the poor".
What you're saying, cikomyr, is we can have as many Three Mile Islands, as many Exxon Valdez oil spills as the companies want to have...as long as they pony up the dough, it's all good. Frankly, that position is FAR MORE repugnant than the position of not doing anything!
