Shared Mobility Benefits Calculator

Shared Transportation Modes Dramatically Reduce Greenhouse Gases

The calculator is an aspirational tool for cities to estimate the emissions benefits from deploying various modes of shared mobility. Using these estimates, policymakers can envision and set goals towards reducing congestion, household transportation costs, and carbon emissions from personal vehicles. Although the benefits estimated by SUMC’s Calculator are ambitious in nature, the numbers behind the impacts represent real possibilities. These figures are derived from research publications and shared mobility user surveys in the US and other developed nations. By incorporating combinations of these modes into city and regional planning, local governments can turn greenhouse gas mitigation goals into concrete plans. For additional information see the Shared Mobility Benefits Calculator Method and How to Use Guide.

Cities can make a huge difference for climate

U.S. Cities with more than 100,000 people are home to 94 million people who need to get to work, run errands, and have fun. All that mobility right now leads to 237 million tonnes of greenhouse gas emissions every year. But with investments in mass transit, electric vehicles, and innovations in shared mobility, those same cities could cut their transportation emissions by 84%.

Just the top 50 cities can change the equation

If the top 50 cities did all they could to cut emissions through shared mobility, their actions alone could save nearly 100 million tonnes of greenhouse gas emissions, every year!

That’s 40% of the total transportation emissions across the U.S.
