There are five areas on which we should focus. First, boosting energy efficiency could cut global energy demand by 20-24 percent of projected 2020 demand. Second, to reduce emissions by one-fifth of current levels by 2020, the carbon productivity of energy sources must increase by two-thirds. Third, additional investment in R&D and incentives to boost innovation will be necessary. Fourth, companies and governments can do more to educate consumers on "green" behavior. Fifth, forestation and avoided forestation offer the largest abatement lever at 25 percent of the global total under €40 per ton.
