Cambridge study of near-term alternative London bus technologies finds lean-burn CNG most costly with greater climate impact than diesel

Green Car Congress

Annual GHG emissions relative to BASE Scenario (BASE Scenario = 949 kt CO 2 e on a 100-year GWP basis) for differing London bus fleet technology options. Their findings indicated that emission control strategy retrofits are the least costly near-term intervention to reduce urban air pollution. Credit: ACS, Chong et al.
