New analysis suggests Uber adding significantly to pollution and traffic in European cities

Green Car Congress

Uber is adding more polluting car trips to already-clogged European cities such as London and Paris, new analysis by European NGOs suggests —contributing to air pollution and climate change and exploding the company’s sustainability claims. Cars emit 44% of transport emissions; these are still rising.

WHO report urges greater attention to improved land use, rapid transit, cycling and walking to achieve health co-benefits from transport GHG emissions mitigation

Green Car Congress

Urban density is one of the most important determinants of car use and transport-related energy consumption in cities. The IPCC’s global assessment of mitigation options for the transport sector places the greatest emphasis on the mitigation potential of improving carbon efficiencies for private vehicles and fuels.

WHO issues new, lower Global Air Quality Guidelines for classical pollutants

Green Car Congress

New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO.

Study Finds On-Road Transportation Sector the Greatest Net Contributor to Atmospheric Warming Now and in Mid-Term; Power Sector Takes the Lead by 2050

Green Car Congress

A new study by led by Nadine Unger at NASA’s Goddard Institute for Space Studies (GISS) that analyzes the net climate impacts of emissions from economic sectors rather than by individual chemical species has found that on-road transportatation is and will be the greatest net contributor to atmospheric warming now and in the near term.

Researchers present new explanation for the long-range transport of PAH pollutants

Green Car Congress

When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).
