2017 U.S.-Booked Air Volume: $120 million
Consolidated U.S. TMC: CWT
Investment bank and financial services firm Citigroup in
2017 saw revenue and some travel activity increase from 2016. The company's
business air travel last year accounted for about 151,100 metric tons of carbon
dioxide equivalent emissions, more than 11 percent higher than in 2016.
However, its 2017 rail travel generated 209 metric tons of such emissions, down
from 2,225 the prior year. Still, Citi has procedures in place to encourage
would-be travelers to consider remote conferencing options instead of
traveling, including a prompt within its online booking system. The company
also encourages employees to group trips together when possible, to reduce
sheer volume of trips and to prioritize rail travel over air when possible.
Net revenue in 2017 increased about 2 percent to $71.5
billion. Operating expenses declined less than half a percentage point to $41.2
billion. Citi at the end of 2017 had about 209,000 full-time employees, about
10,000 fewer than at the end of 2016.
