Study: air pollution caused 1.1M deaths across Africa in 2019, toll from outdoor pollution rising

Green Car Congress

Air pollution was responsible for 1.1 Air pollution was responsible for 1.1 Deaths attributable to household air pollution and ambient particulate matter (PM 2.5 ) air pollution in Ethiopia, Ghana, Rwanda, and overall in Africa, 1990–2019. The most disturbing finding was the increase in deaths from ambient air pollution.

SwRI engineers develop near-zero emissions diesel engine technology; 90% reduction of NOx

Green Car Congress

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. g/hp-hr NO x emissions). Making a relevant impact on pollutants requires a whole system approach.

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?

MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. Electric power generation is the greatest contributor to out-of-state pollution-related deaths, the findings suggest.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then.

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.

Study links increased black carbon pollution to increase in cases of lung adenocarcinoma worldwide

Green Car Congress

An international team of scientists, led by NTU Singapore, has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. The results of the study were published in the journal Atmospheric Environment. Black carbon is a pollutant that is classified as under PM 2.5. micrograms per cubic meter (?g/m
