Buildings generate 48 percent of greenhouse gas emissions in the United States, creating one of the greatest opportunities to take immediate action on climate change.

Green building — a commonsense approach to building design, construction and operations — lays out an organized approach that results in  proven solutions that significantly reduce emissions.

The building industry is the single largest contributor to global warming in the country. Local governments across the nation are finding that green buildings can offer a cost effective solution for achieving measurable reductions in greenhouse gas emissions.
