2021 U.S.-Booked Air Volume: $2 million

BTN estimates British investment bank Barclays reduced its 2021 spending on U.S.-booked air travel notably from 2020 levels. While the pandemic reduced the company’s 2021 emissions generated by its business air travel to just shy of 1,800 metric tons of carbon dioxide equivalent—down from about 19,100 metric tons in 2020 and down 97 percent from 2018 levels—Barclays has instituted a number of general travel-reduction measures, including adjusting travel policy to promote low-emission modes of travel and remote conferencing. Those measures should stay in place even as post-pandemic travel and emissions increase. The company purchases carbon credits to offset its emissions and has been carbon-neutral regarding travel since 2020. Total 2021 group revenue increased to £21.9 billion from £21.8 billion the year prior.
