I've searched around and it is hard to find data on Carbon Credit sales and averages. I can't determine how long it would take to forward sell a large CDM project. I am sure it happens and I've found brief references to the UN setting up a grant for African credits. So far it looks like we should see carbon credit money sometime between next week and 2012. The EU is willing to purchase African CC up to 2020 at least, so that lowers the risk compared to a 2012 deadline. Can anyone offer a better estimation in this regard - I'm running in circles looking for data.
