2021 U.S.-Booked Air Volume: $7.5 million
Banking and financial giant Citigroup’s 2021 U.S.-booked air volume decreased 50 percent year over year, according to a BTN estimate. The company reported full-year 2021 revenue of $71.9 billion, compared with $74.3 billion in 2020.
Citi employees started travelling again in 2021 after the company had restricted crossborder travel in 2020. While others in the banking sector pushed for a return to the office, Citi last year allowed staff to continue working from home on a part-time basis.
Carbon emissions related to air travel in 2021 declined 51.5 percent year over year and emissions related to train travel declined 27 percent. Emissions data related to air travel are now visible in Citi’s booking tool, with plans to also include emissions data for rail travel, hotels and rental cars.
The company had about 221,000 full-time employees at the end of 2021, up about 11,000 year over year.
