What are two methods by which the Environmental Protection Agency can reduce air pollution?

1. Implementing stricter emissions standards for industries and vehicles: The EPA can set limits on the amount of pollutants that industries and vehicles are allowed to emit into the atmosphere. By enforcing these regulations, the EPA can help reduce air pollution from major sources.

2. Promoting clean energy sources and technologies: The EPA can also incentivize the use of cleaner energy sources, such as renewable energy and natural gas, and support the development and implementation of cleaner technologies such as electric vehicles. By shifting towards cleaner energy sources, the EPA can help reduce air pollution from power plants and transportation.
