Why is this a Climate Smart indicator?

  • Transportation generates over half of city-wide greenhouse gas emissions, according to the 2024 communitywide inventory. Reducing the number of miles driven by cars in San José is key to reducing our greenhouse gas emissions.

  • This is why one of the four key strategies in the 2025 Climate Smart Plan Update is to move to reduce the miles we travel in our vehicles by at least 20%.

  • Using alternative commuting options, like public transit or biking, would help reduce VMT and GHG emissions. It would also reduce traffic, air and stormwater pollution, and crashes.   

  • Additionally, people who incorporate active or shared commuting options tend to be healthier and using alternatives to driving alone can reduce transportation costs for households.

What is the City doing to make progress on this indicator?

To reduce webpage clutter, some progress related to this metric is not included on this webpage but can be found on other dashboard webpages. Visit our Public Transit or Complete Streets dashboard pages for information on progress specific to each of these types of strategies.

About the data

Sources & Methods

Data on commute journeys come from Replica. Replica mode share data is generated using a combination of mobile location data, land use information, and travel behavior models to estimate the number of trips taken via various transportation modes within a given region. The data is calibrated against “ground truth” observations—such as traffic counts, transit ridership, economic activity reports, and other public datasets—to improve accuracy.

SOV trips are derived from Replica using US Census data. Replica reports data on auto person trips but does not differentiate between SOV and carpool trips. To reconcile this, US Census data on the average occupancy of carpool trips (table S0801) was used to separate SOV trips from carpool trips.
