Translations:Greenhouse gas emissions by the United States/47/en

Municipal, county, and regional governments have substantial influence on greenhouse gas emissions, and many have reduction goals and programs. Local governments are often one of the largest employers in their jurisdictions, and can achieve substantial reductions in their own operations, such as by using zero-emissions vehicles, making government buildings energy-efficient, making or buying renewable energy, and providing incentives for employees to walk, bike, or take transit to work. Local governments have control over several policy areas which influence emissions for the population as a whole. These include land use regulations such as zoning; transportation infrastructure like public transit, parking, and bike lanes; and building codes and efficiency regulations. Some municipalities act as utility cooperatives and set a minimum standard for renewable generation. Although healthier air is the main benefit of clean air zones in cities they can have a side effect of reducing greenhouse gas emissions: however as of 2025 it is unclear whether cities in the US have the political power to make clean air zones.
