The California Carbon Challenge (game)

3. Cap and trade is arguably one of the most cost effective reductive mechanisms available.

at least according to that program and the research the put into it.

But since it's a game you can pick what you want and how you want to achieve emissions reductions. You can annihilate emissions (90% reduction) for a measly ten billion dollars in the most prosperous state in the union (we're something like 9-11% of the US GDP). That's food for thought, we could cut US National greenhouse emission by 90% for 100-200 Billion dollars if it scales properly (not all of which would be borne by the government, large amounts come from individuals and businesses). Which is a third of the defense budget for a single year, and it would create massive employment opportunities during the retrofit.

The thing I like about these 'games' that next 10 releases is that they source their research so you can delve deeper into the subject if you choose to do so. A large number of their data points appear to come from a non-profit group called blue sky. So you can dig and find an agenda. It's also a mildly entertaining way to get a little bit more education about the subject and potentially expose others to it.
