Advancing green buildings can have the single greatest impact on greenhouse gas emissions reductions of any local government strategy.  Consider:

• Energy Use: The energy used to operate buildings accounts for 39 percent of carbon dioxide emissions and 48 percent of all greenhouse gases in the United States.
• Growing Emissions: Reflecting the projected growth in the U.S. population and economy, it is anticipated that greenhouse gas emissions from buildings will continue to grow, and at a faster rate than any other sector.
• Standards:  Green building standards reduce direct greenhouse gas emissions by advancing energy efficiency, building commissioning, renewable energy, and green power. 
• Cost: Green buildings are cost-effective, provide healthy places for people to live, learn and work, and support municipal conservation and environmental goals.
• Achievements: Mayors and county executives across the nation are practicing and promoting green building in their communities, achieving measurable greenhouse gas emissions reductions, and spurring the green building movement.
