UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. —Ryan et al. —Ryan et al.

UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said. Click to enlarge. °C (within a likely range of 0.2-0.7

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

Scaling of industry sales statistics enabled the discrepancy to be attributed to the use of ancillary solvent products such as screenwash and deicer which are not included in internationally applied vehicle emission methodologies. —Cliff et al. the products used for “car care,” such as windshield washer fluid.

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

This study will measure concentrations of non-tailpipe (NTP) particulate matter across Toronto, Canada to determine how much non-tailpipe pollution people might breathe in everyday life and how to better measure these exposures in the future. Establish a bio-bank of samples to support future HEI-sponsored research in this area.

Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

The researchers analyzed extensive satellite and ground-based measurements of nitrogen oxides and carbon monoxide. They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency.
