BTN estimates Big Four accounting and professional services firm PwC spent $19,3 million in U.S.-booked air volume, about a third of what it spent the previous year and only about 6 percent of its 2019 volume.
In terms of carbon dioxide emissions related to air travel, PwC reported 29,177 metric tons for the 2021 fiscal year, which ended June 30, 2021. That is a decrease of more than 90 percent year over year, which the company attributes to restrictions on both domestic and international air travel. For the longer term, the firm has pledged a 50 percent absolute reduction in business travel emissions from 2019 levels, noting that air travel, along with electricity, is its biggest source of carbon emissions.

PwC also has committed to ensuring at least 50 percent of its suppliers for goods and services have set their own science-based targets to reduce their climate impact by 2025.

The firm’s gross revenue for FY2021 increased 2 percent compared with the previous year to $45 billion. PwC reported 295,000 employees as of the 2021 fiscal year, an increase of 3.9 percent year over year.
