Clean Transportation
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!
