ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions.

UNICEF: 300M children worldwide breathing air exceeding WHO pollution guidelines by 6x or more

Green Car Congress

Almost one in seven of the world’s children, 300 million, live in areas with the most toxic levels of outdoor air pollution—six or more times higher than international guidelines set by the UN’s World Health Organization (WHO)— according to a new UNICEF report. No society can afford to ignore air pollution.

Researchers suggest that air quality tests need simplifying to help reduce dangerous emissions

Green Car Congress

New methods of testing and simulating air quality should be considered in order to help policy makers have a more accurate understanding of how emissions affect air pollution levels, new research suggests. The researchers compared current techniques used to describe atmospheric chemical reactions against more historical techniques.

Kanazawa University-led researchers recycle rare-earth elements from spent fluorescent lamps by chemical/mechanical treatment

Green Car Congress

End-of-life FLs are a potentially huge source of REs, but harsh and polluting processes are needed currently to extract these metals from the spent phosphors. As reported in Waste Management , instead of using acid extractants to dissolve the REs trapped in the spent lamps, the Kanazawa team turned to chelator chemistry.

Study finds relying on “local food” a distant dream for most of the world

Green Car Congress

In comparison, the global average is about 3,800 kilometers. The researchers modeled globally the distances between production and the consumer for both normal production conditions and scenarios where production chains become more efficient due to reduced food waste and improved farming methods. —Pekka Kinnunen, lead author.

Comprehensive LCA report from Ricardo on behalf of EC confirms environmental benefits of electrified powertrains

Green Car Congress

In addition to greenhouse gas emissions, the report also assesses a number of other environmental impact categories, ranging from resource use, including cumulative energy consumption, mineral and metal resource depletion and water scarcity, to airborne pollutant emissions (like particulates and nitrogen oxides), and human- and eco-toxicity.
