More Foot Power, Less Car Pollution Best for Health

Walking and cycling plus low-emission vehicles may reduce future disease burden, researchers say

(HealthDay News) -- Encouraging city dwellers to walk and bicycle instead of using cars would offer much greater public health benefits than increased used of low-emission vehicles, U.K. researchers have found.

The study compared the projected health effects in 2030 of alternative urban land transport scenarios for London, England, and Delhi, India: business-as-usual (no greenhouse gas reduction policies); motor vehicles with lower carbon emissions; increased walking and cycling (active travel) plus less motor vehicle traffic; and a combination of increased walking/cycling and low-emission vehicles.

In both cities, reductions in carbon dioxide emissions achieved through increased active travel and less use of motor vehicles offered much greater health benefits than increased use of low-emission vehicles. The benefit was over 40 times greater in London and over seven times greater in Delhi. The greatest health benefits would be achieved by combining active travel and increased use of low-emission vehicles, according to the report published online Nov. 27 in The Lancet. Read more...
