Vehicle Idling & Diesel Emissions
Transportation emissions are a major source of air pollution. Idling vehicles on residential streets can also be a nuisance and health concern for neighbors unsure of their options to address the issue.
Air pollution related to diesel-powered vehicles and idling is an issue that GASP has been keeping an eye on for decades. While most air pollution from vehicles may happen while they're on the road, a lot of easily avoidable pollution happens while vehicles idle, parked with the engine running. Learn more about GASP's work related to diesel here, including our campaigns for clean construction and school bus idling.

See the Pennsylvania Diesel Idling Restrictions - Act 124 of 2008, which authorizes the state DEP to enforce the act, including context and links to local regulations. Note that there are many exceptions to when these diesel idling regulations can be enforced.
Diesel exhaust is a major source of air pollution, and is made up of a mixture of gases and fine particles.
A child's respiratory systems is still developing. 90% of school buses still run on diesel. Approximately 60% of low-income children in the United States take the school bus daily, compared to about 45% of high-income children. Low-income students are disproportionately exposed to diesel emissions.
