UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario.

EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. We already know that climate change will bring us increased forest fires, shorter winters, hotter summers and impact our water supply.

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.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

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
