DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Small particles in exhaust from burning fossil fuels creates “seeds” on which water vapor in the air can condense into cloud droplets. C, or 1.8 ?F, F, since the late 1800s.).

UK ONS report finds significant challenge remains to reduce road transport emissions; sector GHG emissions up 6% from 1990-2017

Green Car Congress

A new report by the UK’s Office for National Statistics (ONS) finds that greenhouse gas (GHG) emissions from road transport in the UK rose by 6% from 1990 to 2017. Source: Office for National Statistics – UK Environmental Accounts, Energy Use datasets. Among the other findings of the report: At the end of 2018, 0.5%

Study Measures the Effect of Fischer-Tropsch Synthetic Jet Fuel on Emissions

Green Car Congress

While CO 2 emissions are likely important for estimating global climate change impacts, a recent report on the climate change potential of aviation suggests that emissions other than CO 2 , including soot and NO x , need to be included in forecasts of potential aviation induced global climate change.

International automotive researchers emphasize the importance of continued development of the internal combustion engine

Green Car Congress

The editorial addresses important issues in the current politically charged discussions of global warming and climate-change alarm. … This could be paired with combustion technologies with highly diluted combustion (stoichiometric with exhaust gas recirculation (EGR) as well as lean burn with excess-air ratios above 2).

OECD: rising air pollution-related deaths taking heavy toll on society; more should be done to reduce transport emissions

Green Car Congress

Traffic exhaust is a growing threat in fast-expanding cities in China and India, as the steady increase in the number of cars and trucks on the road undermines efforts to curb vehicle emissions. This pollution is costing advanced economies plus China and India an estimated US$3.5 Over the five?

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al. of the data.
