Clean Transportation

Transportation is a major source of air pollution and has the largest, fastest-growing climate emissions in the US. We can tackle the climate crisis and clean up our air by shifting to pollution-free vehicles, accessible public transit, and making our communities more walkable, bikeable, and transit-friendly. No matter their zip code, race, income level, age, or any other factor people should be able to rely on clean and safe transportation. Join the Sierra Club’s Clean Transportation for All campaign in making that vision a reality!


Clean Transportation For All

The Sierra Club’s Clean Transportation For All (CTFA) campaign reduces the harmful environmental and public health impacts of transporting people and goods while expanding equitable transportation options.

Land Use & Walking/Biking

Sierra Club chapters nationwide are working with cities, regions, states, and transit agencies to increase investment in biking, pedestrian, and public transit programs. Together, we can pass transportation policies that encourage smart growth and discourage sprawl to allow people to sustainably access jobs, housing, education, healthcare, nature, and community.
