UK ONS report finds significant challenge remains to reduce road transport emissions; sector GHG emissions up 6% from 1990-2017

SEPTEMBER 17, 2019

A new report by the UK’s Office for National Statistics (ONS) finds that greenhouse gas (GHG) emissions from road transport in the UK rose by 6% from 1990 to 2017. The increase—albeit lower than the increase in road traffic—highlights the significant challenge in reducing emissions from road transport, the report says.

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. A container ship leaves a trail of white clouds in its wake that can linger in the air for hours.
