of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. The study was published in the journal Atmospheric Environment. This new study is based on a thorough review of a decade of research on aviation emissions.

T&E study finds plug-in hybrids show higher CO2 emissions than claimed

Green Car Congress

Three of the most popular plug-in hybrids in 2020 all emitted more CO 2 than advertised when tested in the real world, according to tests commissioned by European environmental NGO Transport & Environment (T&E). T&E said the EU should end this weakening of the regulation when it reviews the targets for 2025 and 2030 next year.

U Mich professor finds fuel cycle analysis for evaluating CO2 impacts of liquid fuels is fatally flawed; calls for focus on CO2 removal

Green Car Congress

Fuel cycle analysis (FCA)—or “well-to-wheels analysis”—is a type lifecycle analysis (LCA) that examines fuel products and their supply chains, and that has greatly influenced climate-related research priorities and public policies for transportation fuels. This is where biofuels come in, as carbon is fixed during feedstock growth.
