Boosting public transit ridership can directly reduce greenhouse gas (GHG) emissions by displacing trips made by single-occupancy vehicles. Public transit expansion includes both system expansion, such as building an entirely new light rail or bus rapid transit line, or service expansion, such as increased frequency or extended service hours for an existing bus line. Expanding transit services can provide more people with more opportunities to use transit to reach their destinations, and in turn reduce GHG emissions. Transit investments also indirectly reduce GHG emissions by enabling compact, mixed-use development that reduces distances traveled between destinations. These indirect effects of transit funding are more difficult to measure, but potentially just as impactful or even more so than direct effects in the long run.
