Study Finds That Climate Change Mitigation in Land Transport Should Benefit Public Health Substantially

Green Car Congress

A new study by an international team of researchers using Comparative Risk Assessment methods to estimate the health effects of alternative urban land transport scenarios for two settings—London, UK, and Delhi, India—concluded that although uncertainties remain, climate change mitigation in transport should benefit public health substantially.

Researchers measure actual CO2 emissions from fossil fuel use and compare to reported levels

Green Car Congress

Researchers have measured CO 2 emissions from fossil fuel use in California and compared them to reported emissions. This is the first time fossil fuel emissions have been independently checked for such a large area. The researchers found there was a good match between the different estimates.

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.
