They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane. Based on their findings, they suggested that emission increases in Southeast, East and South Asia may be most important for the ozone change.
The California Air Resources Board’s latest state inventory of greenhouse gas emissions shows that California’s GHG emissions continue to decrease. Compared to 2016, California’s GDP grew 3.6% Trends in California GHG Emissions. Changes in emissions by Scoping Plan sector between 2000 and 2017. Source: ARB.
Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new study by researchers at NOAA and their colleagues shows. However, that decrease is significantly slower than it would be without the new CFC emissions.
High levels of air pollutants, especially fine particulate matter (PM 2.5 ) and to a lesser extent, ozone, may be linked to a heightened risk of developing mouth cancer, suggests a study by a team of Taiwanese researchers. A significant association was also observed for ozone levels below 28.69-30.97 µg/m 3 , those above 40.37

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.
A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. The monitoring methods can quickly and accurately detect ozone anomalies—localized spikes in ozone concentration indicated by sensor data.
Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.
The At-Berth Regulation is a critical tool for CARB to cut harmful toxic diesel emissions from ships docked in California ports, and we hope this penalty will send a message that violators will pay a hefty price if they fail to comply. The goal of CARB’s At-Berth Regulation is to reduce diesel emissions from ocean-going vessels (OGVs).
Air pollution—specifically PM 2.5 , ozone and NO 2 —could be to blame for up to 33 million emergency asthma attack visits to hospital a year, according to a new open-access study published in the journal Environmental Health Perspectives.

Ethane reacts with sunlight and other molecules in the atmosphere to form ozone, which at the surface can cause respiratory problems, eye irritation and other ailments and damage crops. Two percent might not sound like a lot, but the emissions we observed in this single region are 10 to 100 times larger than reported in inventories.
EPA has proposed a new to reduce emissions of hydrofluorocarbons (HFCs), potent greenhouse gases used in refrigeration and air conditioning. EPA is also proposing numerous changes to the National Recycling and Emission Reduction Program. After reviewing public comments, EPA plans to finalize this rule in 2016.

SLCPs include black carbon (soot), methane and hydrofluorocarbons (HFCs)—the fastest-growing source of GHG emissions in California and globally—which are used as refrigerants, aerosol propellants and insulation. Therefore a target for forest-derived black carbon emission reductions is not included in the SLCP Strategy.

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The last of these issues was perhaps the most vexing, prompting the U.S. Boom Supersonic.
million shares of an almost $3 billion settlement in 2016 between the U.S. Volkswagen sold about 590,000 vehicles equipped with devices that defeated their pollution control features, leading to increased emissions of oxide. Net-zero carbon emissions by 2050 are the governor’s goal. Another $7.3
