Two new studies of road air pollution in London find detrimental effects on over-60s and unborn babies

Green Car Congress

Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in adults over 60, according to new research led by Imperial College London and Duke University. Our research suggests that we might advise older adults to walk in green spaces, away from built-up areas and pollution from traffic.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Shifting to electric vehicles could also reduce noise pollution, especially in cities where speeds are generally low and traffic often stands still.
