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. For the lean-burn CNG scenario, this meant considering exhaust and pipeline supply leaks. Lean-burn CNG is disadvantaged by unburned HC and natural gas pipeline leaks.
