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.

T&E: Rising use of private jets sends CO2 emissions soaring

Green Car Congress

CO 2 emissions from private jets in Europe increased by nearly a third (31%) between 2005 and 2019, rising faster than commercial aviation emissions, according to a new report from environmental campaign group Transport & Environment (T&E). The report, Private jets: can the super-rich supercharge zero emission aviation?

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. A study by Mark Z.

Researchers use satellite data to show vehicles are an under-recognized source of urban ammonia pollution

Green Car Congress

By disrupting normal societal activities such as driving, COVID-19 lockdowns afforded a unique opportunity to study their impacts on the environment. On a national or global scale, most NH 3 pollution comes from agricultural sources, such as livestock manure. The team analyzed satellite readings of NH 3 , as well as NO 2. 1c00730.
