Scientific evidence has shown that since the beginning of the industrial revolution, human activities have been adding measurably to natural levels of carbon dioxide and other greenhouse gases (GHG). These gases accumulate in the upper atmosphere and trap heat near the earth’s surface -- resulting in a “greenhouse” effect.
Climate change is an issue of growing concern for communities across the United States and around the world. The city of Phoenix recognizes that climate change may impact our residents, businesses and natural resources. The 2006 Arizona Climate Action Plan reports that global warming impacts in Arizona may include increased drought, reduced water supply, loss of forest areas and increased air pollution.
The primary source of greenhouse gas emissions is burning of fuels (coal, natural and petroleum) to produce electricity and to operate vehicles and other engines. Chemicals from industrial processes and methane from landfills, wastewater treatment and animal feed lots also contribute to the problem. Although the federal government has the primary authority to address the causes of global warming, local governments also can make a difference.
Phoenix is one of the first cities in the state to develop a Climate Action Plan, which defines how the city will reduce emissions from city operations. The greenhouse gas reduction measures in the plan also will expand the city’s use of solar and other renewable energy, reduce energy use, support alternative fuels and help achieve a more a sustainable future.
The Climate Action Plan for the city of Phoenix defines how the city will achieve a goal to:
Reduce greenhouse gas (GHG) emissions from city operations
to 5 percent below the 2005 levels by 2015.
