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.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then.

MIT study finds real-world NOx from diesels cars in Europe greatly exceeds laboratory levels; transboundary emissions cause 70% of health impacts

Green Car Congress

A new study by MIT researchers, published this month in Atmospheric Environment , finds that in Europe, 10 major auto manufacturers produced diesel cars, sold between 2000 and 2015, that generate up to 16 times more NO x emissions on the road than in regulatory tests—a level that exceeds European limits but does not violate any EU laws.

QUANTIFY Study Finds GHG Emissions from Global Transport Could Double Their Net Contribution to Warming by 2100

Green Car Congress

Transport emissions could double their current relative net contribution to global warming by 2100, according to a new study by researchers at the Oslo-based Centre for International Climate and Environment Research (CICERO) in Norway. More travelling and international trade drive the emission increase. million (US$12.6
