Global study links daily exposure to ozone pollution to increased risk of death

Green Car Congress

Daily exposure to ground level ozone in cities worldwide is associated with an increased risk of death, according to the largest study of its kind, published in an open-access paper in The BMJ. Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight.

Duke/York study finds long-term exposure to ozone has significant impacts on human health, but lower than prior modeling results

Green Car Congress

A team from Duke University in the US and University of York in the UK have utilized a novel method to estimate long-term ozone exposure and previously reported epidemiological results to quantify the health burden from long-term ozone exposure in three major regions of the world. —Seltzer et al. —Karl Seltzer.

Study uncovers role of longer-chain unburned hydrocarbon emissions from diesels in London air pollution; calls for regulatory shift

Green Car Congress

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London. 15, 9983-9996, doi: 10.5194/acp-15-9983-2015.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

As with the earlier assessment, this study consists of two separate, but related, analyses: greenhouse gas emissions from 2015-2050, and air quality impacts in 2030. This research points to the importance of two fundamental and parallel trends in energy and the environment. —Mike Howard, EPRI president and CEO.
