A new study shows carbon pollution on the same route can vary sharply but consumers currently cannot make informed choices

Commercial flying is a real carbon bomb as emissions from commercial aviation are growing rapidly and are on track to triple by 2050, when they could make up about a quarter of the global carbon budget.

But now a new study shows how people could reduce their emissions while still flying on airplanes, if they were able to choose the most carbon-friendly routes.
