Massive Good—an initiative that allows people to make $2 contributions toward global health causes, including HIV/AIDS, every time they buy a plane ticket—has launched a new program, Massive Good Corporate, which allows business travelers to do the same.

The corporate program was unveiled during this year’s annual conference of the Global Business Coalition for HIV/AIDS, Malaria and Tuberculosis (GBC), held in Washington, DC.

Participating companies can now integrate the donation software into their corporate travel systems.

During the GBC conference, Marathon Oil announced that it would be the first Massive Good corporate client and offered a donation of $50,000. That amount represents $2 for the next 25,000 business trips of its employees, which is about a year’s worth of travel for the company.
