cec.org: Promoting the green design, construction, renovation and operation of buildings could cut North American greenhouse gas emissions that are fuelling climate change more deeply, quickly and cheaply than any other available measure, according to a new report issued by the trinational Commission for Environmental Cooperation (CEC).

North America’s buildings cause the annual release of more than 2,200 megatons of CO2 into the atmosphere, about 35 percent of the continent’s total. The report says rapid market uptake of currently available and emerging advanced energy-saving technologies could result in over 1,700 fewer megatons of CO2 emissions in 2030, compared to projected emissions that year following a business-as-usual approach. A cut of that size would nearly equal the CO2 emitted by the entire US transportation sector in 2000. [ read more ]
