Illustrated comparison inspired by the place and case. Conceptual scenes, not a photographic before and after.
How the change works
- 01 / Public decision
Limits, monitoring and controls
- 02 / Physical change
Fewer pollutants emitted
- 03 / Possible outcome
Lower exposure of people and ecosystems
Applicable limits and checks reduce the pollutants emitted by plants and vehicles, protecting health and ecosystems.
Research and local documents ↓What the evidence tells us
The Clean Air Act's EPA assessments compare program costs with health, ecological, and economic benefits and find overall benefits that outweigh costs.
Conditions and limits
Many benefits are estimated with models. Reducing air pollutants does not automatically equal the same reduction in CO₂.
Other possible benefits
Health benefits and less economic damage.
