Taking a plane to a climate conference may seem like an obvious initiation for criticism but UK's Transport Secretary Grant Shapps said it should not be treated as the "ultimate evil".
Shapp's comments addressed disapproval some delegates received about flying to the Cop26 summit when more sustainable transport options were available.
Day nine of Cop26 was focused on transport and Britain announced their plan to phase out petrol cars from 2030 and polluting heavy goods vehicles from 2040 to cut carbon emissions.
In addition, they revealed plans to build electric charging stations that would support low-carbon road transport.
However, Shapps told the Daily Telegraph that these green plans shouldn't stop people from travelling to see family, friends or for business.
