Public Bus Fleet Electrification (Solution Type)

Global (widely applicable)

Highlight

Replacing diesel buses with electric fleets to cut CO2 and local air pollution in cities.

Extended description

Electrifying public bus fleets, replacing diesel buses with battery-electric vehicles, is one of the highest-impact urban mobility measures. Sector analyses show major reductions in CO2 and local pollutants; for example, C40's analysis for New York associates a full fleet transition with over 500,000 tonnes of CO2 avoided. Alongside emissions cuts, electric buses reduce noise and improve air quality. This is a general, replicable solution type deployed by many cities.
