Climate Change/Carbon Offsets is pure Capitalism. They have created a Need based product to sell to the world market. Once they pull off changing the laws to require this product be sold to everyone eventually, they will have more money than any single nation. The only thing standing in their way is their own greed once the money starts pouring in.
Maybe you're being sarcastic with your comment about changing the law to "require" the product to be sold? If it's pure "capitalism" as you say, then why do the carbon offsets have to be centrally enforced through Kyoto? If it's truly a need-based program and not a top-down socialist grab for power, wouldn't venture capitalists see the profit potential in these enterprises without being forced to? Wouldn't the profits flow to investors and not lawyers and brokers? It's pure totalitarian socialism on a worldwide scale.
