How can greenhouse gas emissions from buildings be reduced?

The IPCC estimates that buildings will account for over 25 percent of global greenhouse gas emissions in 2030 and that nearly half of these emissions can be avoided at modest cost. This contest seeks proposals on how emissions from buildings can be reduced, with a focus on increasing energy efficiency. See more...
