In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. Over the course of five years, PM 2.5

In China, people breathe ozone-laden air two to six times more often than people in the United States, Europe, Japan, or South Korea, according to a new international study published in Environmental Science & Technology Letters. 2017 for one ozone metric. For China, sites in 74 major cities with continuous observations from 2013?2017

Counties where measured ozone is above proposed range of standards, based on 2011-2013 monitoring data. Earlier this year, EPA staff had recommended the further reduction of this primary ozone standard from the current 75 ppb (parts per billion) to a revised level within the range of 70 ppb to 60 ppb—and preferably below 70 ppb.

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

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.
