Clean Transportation For All

Sierra Club believes that everyone deserves access to a transportation system that protects our climate, keeps us healthy, and connects us to the places where we live, work, and play.  

  • Currently, the transportation sector is the largest and fastest-growing source of climate disrupting pollution in Maryland and the United States. In Maryland, the transportation sector-- which includes cars, buses, trucks, planes, trains, ships, and freight—produces approximately 38 percent of all climate damaging pollution in the state.

  • Tailpipe emissions from gas and diesel-powered vehicles are the largest source of health damaging pollution which is responsible for 1 in 5 childhood asthma cases, and are also linked with various cancers, heart disease, emphysema and other respiratory diseases that may lead to premature death.  

  • Our transportation system doesn’t work for everyone. Many Marylanders don’t have reliable transportation to access affordable housing, jobs, food, healthcare, and amenities. 

But this doesn’t have to be the case.

Together, we are fighting to:

  • Reduce pollution from the cars and trucks we drive and the buses our children take to and from school.

  • Strengthen and expand public transit.

  • Promote transit oriented and walkable and bikeable communities.

  • Promote electric cars, trucks and buses powered by renewable energy.

  • Stop highway expansion because it attracts more drivers which leads to increased climate and health-damaging air pollution, more sprawl, more natural places destroyed, traffic congestion again in a short time, and it takes funding away from clean mobility alternatives.  

Join our campaigns to make clean transportation for all a reality in Maryland!
