HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The University of Bremen is the scientific base of the international project known as EMeRGe (Effect of Megacities on the transport and transformation of pollutants on the Regional and Global scales).

New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions. In Europe, where diesel-passenger cars are common, 28,500 deaths annually are attributed to diesel NO x pollution, with 11,500 of those deaths linked to excess emissions.

Study finds anthropogenic PM and dust undercutting global solar energy production

Green Car Congress

Percent reduction in visible solar energy due to ambient PM (plus a small contribution from ozone) (A), only dust PM deposition (B) deposition of all PM components (C), and atmospheric and deposited combined (D; note change in scale). The Arabian Peninsula loses much more solar power to dust than it does manmade pollutants, Bergin said.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

The update identifies eight key sectors for ongoing action: Energy; Transportation, fuels, land use and infrastructure; Agriculture; Water; Waste management; Natural lands; Short-Lived Climate Pollutants (such as methane and black carbon); and Green Buildings. The Air Resources Board is required to update the Scoping Plan every five years.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?

California ARB LEV III Concept Targeting Fleet-Average SULEV-Level Emissions Performance from New Vehicles by MY 2022

Green Car Congress

Illustration of light-duty vehicle sales share by emission certification level projected to be required to meet. The existing LEV II program regulates emissions from new light-duty vehicles, including include all passenger cars, light trucks, and medium-duty passenger vehicles. proposed NMOG+NO x standards in new LEV III.

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

Green Car Congress

Recent studies have compared emissions of PFI and GDI vehicles, including particle number and mass, gaseous pollutants, and nonmethane organic gas (NMOG) composition for a limited number of compounds. We estimate ozone and SOA formation potential. Finally, we analyze the potential climate effects of switching a PFI to a GDI fleet.
