As the U.S.-booked air volume for German conglomerate Siemens begins to recover, the company's travel management program has evolved with an eye toward sustainability.

Siemens in 2022 revised its global travel policy to include sustainability as an official consideration for trip planning. Additionally, the company has expanded its electric vehicle rental program, and is promoting EV adoption through test-drive programs, traveler education, and communications campaigns. The company also is exploring new technology to enable travelers to identify more sustainable accommodation options at the point of booking. 

Siemens has made changes to its program outside of environmental efforts. The company in 2022 engaged in a global car rental request for proposals and tested virtual payment solutions. In 2023, the company is looking at ways to further integrate its meetings and events management programs with its transient travel management operations.

The company has consolidated U.S. travel management services with BCD Travel, which also offers most global services, though CWT holds some of the company's operations in Asia.  

The company at the end of September 2022 had about 311,000 employees worldwide, up about 8,000 from one year prior. Siemens allows for several days of remote work per week, as determined by local management. Total 2022 revenue increased more than 15 percent year over year to nearly €72 billion.
