WHO issues new, lower Global Air Quality Guidelines for classical pollutants

Green Car Congress

New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO.

Study: air pollution causes 800,000 extra deaths a year in Europe and 8.8 million worldwide

Green Car Congress

Air pollution could be causing double the number of excess deaths a year in Europe than has been estimated previously, according to a study published in the European Heart Journal. Air pollution caused twice as many deaths from CVD as from respiratory diseases. The researchers found that air pollution caused an estimated 8.8

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

Fortunately, we still have a narrow window of opportunity to alter the Earth’s climate path, and I believe we can do it. Climate change is a global societal crisis that is causing devastating consequences. More than half the world’s people live in urban areas, yet only 12 percent of cities achieve WHO guidelines for air quality.

Black carbon linked to increased cardiovascular risk; exacerbated by co-exposure to motor vehicle emissions

Green Car Congress

Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. Air pollution mitigation efforts focusing on reducing combustion pollution are likely to have major benefits for climate and human health.

EPA issues final actions to cut methane emissions from municipal solid waste landfills

Green Car Congress

In a separate action, EPA also issued revised guidelines for reducing emissions from existing MSW landfills, updating the previous Emissions Guidelines, which also were issued in 1996. The NMOC portion of LFG can contain various organic HAPs (hazardous air pollutants) and VOCs (volatile organic compounds).

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

Specifically, the EPA is proposing state-specific rate-based goals for carbon dioxide emissions from the power sector, as well as emission guidelines for states to use in developing plans to attain the state-specific goals. Cutting particle pollution, nitrogen NO x , and SO x by more than 25% as a co-benefit.
