An organization led by North America's top environmental officials has issued a new report calling for greater international collaboration to build green. The Commission for Environmental Cooperation (CEC), formed to address environmental concerns within North America's free-trading nations, stated the need for "a lasting and achievable vision" of green buildings. The vision for Canada, the United States, and Mexico includes the creation of stakeholder task forces in each country, targets to build net zero-energy buildings, and the promotion of private sector financing.
