Issue Summary

Climate change is caused by the accumulation of heat-trapping substances, known as greenhouse gases (GHGs), in Earth's atmosphere. Though many localities are already experiencing the impacts of climate change, experts agree that future adverse effects, including sea level rise, flooding, coastal erosion, drought, heat waves, wildfires and more frequent and severe extreme weather events, can still be reduced or averted by prompt, decisive action.

Mitigation refers to measures that help to prevent climate change by limiting GHG      emissions. Local governments can reduce their communities' emissions using a wide range of strategies, influencing activities such as energy production, energy management, the built environment, government operations, transportation, water, wastewater and solid waste management.

EXECUTIVE ORDERS

The president issued executive orders addressing national climate change mitigation actions, including rejoining the Paris Climate Accords. Some of these call for implementation through federal actions and funding decisions that may affect local governments.
