2025 U.S.-Booked Air Volume: $168M
Consolidated U.S. TMC: Amex GBT
BTN estimates that Boston Consulting Group spent $168 million on U.S.-booked air in 2025 amid a continued push by the global consulting firm to reduce its carbon emissions related to travel.
For 2025, BCG reported 285,400 metric tons of carbon dioxide equivalent emissions related to business travel, a reduction of 14 percent year over year. In terms of carbon emissions related to business travel per full-time employee, BCG has reduced that figure by 60 percent since 2025, beating its goal of a reduction of 48.5 percent by that year. Business travel is by far the largest source of emissions for BCG, with the second-highest source, its supply chain, accounting for 67,200 metric tons of emissions in 2025.
The reduction has come as a result of cascading carbon budgets within BCG's business units, a continuously updated co-location model for teams to optimize travel, an internal carbon charge to incentivize eco-friendly decisions and providing travelers greener options through their online booking tool. BCG also promotes train travel over flights when possible.
For meetings and events, BCG has a CO2 optimizer that helps it choose locations that have the lowest CO2 emissions and costs for travelers.
In addition, BCG has pledged to replace at least 5 percent of its indirect jet fuel consumption with sustainable aviation fuel. The firm has signed SAF offtake deals that will together reduce emissions by more than 100,000 metric tons over the coming years.
BCG reported $14.4 billion in revenue for 2025, up 7 percent year over year. Its workforce in 2025 grew to 33,500, up from 33,000 in 2024, and the company reported that employees are now using AI tools for their work daily.
