Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

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. This new study is based on a thorough review of a decade of research on aviation emissions. The formation and emission of sulfate aerosol yields a negative (cooling) term.

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.

EEA: almost all Euro car makers met specific 2017 CO2 targets on new sales, but emissions up year-on-year

Green Car Congress

All but three European car manufacturers met their specific emission targets in 2017, based on current European vehicle test rules. Nevertheless, average carbon dioxide (CO 2 ) emissions from new cars sold in the European Union in 2017 rose by 0.4g The final data show that average CO 2 emissions of a new car sold in the EU rose by 0.4

Study finds lead from leaded gasoline persists in London air despite ‘90s ban

Green Car Congress

Lead has historically been used in a variety of ways, from fuel, batteries, alloys and solders to piping and paint in homes and buildings; until 1999, leaded gasoline remained the primary source of lead emissions in the UK atmosphere.

Columbia team organizes available scientific evidence on the effects of air pollution on children’s health

Green Car Congress

Policies to reduce fossil fuel emissions serve a dual purpose, both reducing air pollution and mitigating climate change, with sizable combined health and economic benefits. The new paper aggregates research on outcomes, including adverse birth outcomes, cognitive and behavioral problems, and asthma incidence. Resources. Ashrafi, P.
