STUDY SHOWS BIG IMPACT OF ROAD IMPACT ON ENVIRONMENT

SCIENTIFIC BLOGGING - Breaking down the transport sector to four
subsectors: road transport, aviation, rail, and shipping, five
researchers at the Centre for International Climate and Environmental
Research have calculated each subsector's contribution to global
warming. The researchers have looked at the radiative forcing caused by
transport emissions. . .

The study concludes that, since pre-industrial times, 15% of the RF
caused by man-made CO2-emissions have come from the transport sector.
The study also looks at other emissions. . .

The study implies that more attention needs to be put on the fast
growing road sector. Looking solely at CO2 emissions, road traffic alone
has led to two-thirds of the warming caused by total transport emissions
. . .

Including all gases, not just CO2, and looking at the effect today's
road emissions has on future climate, the share is even larger: the road
emissions of today will constitute three-fourth of the warming caused by
transport over the next hundred years. . .

Aviation has a strong contribution to global warming but the historical
contribution to global warming from aviation is more than doubled by the
contribution from road emissions. Over the next 100 years, today's road
emissions will have a climate effect that is four times higher than the
climate effect from today's aviation emissions.

The warming effect by rail emissions is very small, almost not
noticeable at all, compared to the effects from road transport and
aviation.
