Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. There was so much particulate matter in Chinese cities that it stunted the ozone production.

TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.

Fraunhofer IFF team designing hydrogen factory of the future

Green Car Congress

The hydrogen is stored and can be converted by fuel cells in vehicles back into electricity that powers them. The hydrogen produced during electrolysis can be injected into the gas grid, used as fuel, converted into methane or methanol, and made available as industrial feedstock.

Report: 4 of 10 Americans live with unhealthy air, and EVs can help

Baua Electric

That’s based on air quality assessment data from 2020-2022 (the most recent available), and accounting for new EPA particulate-pollution rules finalized in February 2024. ” But the organization is now pushing for stricter national limits on ozone pollution as well. Power-plant emissions remain an issue as well.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels.
