Study finds that replacement programs that reduce vehicle lifetime can result in increased lifecycle CO2 emissions

Green Car Congress

Conversely, encouraging shortened vehicle lifetime via vehicle replacement schemes can result in higher total-induced greenhouse gas emissions, the authors found. This finding implies that the product lifetime extension scenario would clearly contribute to a reduction in carbon emissions, the authors said. Technol. ,

Perspective: Drive Star Conversion Program Could Cut US Oil Use in Half by 2020

Green Car Congress

For $100 million in one year, we’ll demonstrate how to rapidly reduce use of oil in transportation with safe, warrantied retrofits of tens of millions gas-guzzlers. We now have a sprinkling of promising companies working to get funded to convert gas-guzzlers. In the key area of transportation, we submit our Drive Star proposal.
