Campaigners call for transport overhaul to tackle pollution

Measures to cut emissions could include free bus travel, says Friends of the Earth

Campaigners have called for free bus travel and the reopening of hundreds of miles of railway lines to end reliance on cars, as transport is due to be confirmed as the UK's largest contributor to greenhouse gases.

Official data released on Tuesday is expected to confirm transport as the most polluting sector, largely driven by cars. It outstripped energy for the first time in 2016, with annual emissions of about 125m tonnes of CO₂. This figure has barely changed since 1990.
