Our GHG emissions primarily result from business travel and purchased goods and services. In fiscal 2025, we maintained 100% renewable electricity in our facilities through the purchase of renewable electricity contracts equivalent to the amount of electricity we consume.
As of the end of fiscal 2025, our Scope 1 and 2 emissions decreased 91% from our fiscal 2019 base year against our 2030 target, primarily due to a mix of maintaining 100% renewable electricity in our facilities, as well as driving energy-efficient practices where possible. Our Scope 3 emissions per unit of revenue decreased by 61% against our 2030 target.
We continue to strive to reduce or mitigate increases in our Scope 3 emissions, by leveraging digital tools to meet client needs while minimizing travel where feasible; encouraging our people to make climate-smart travel decisions; working together with our suppliers to decarbonize business travel, set environmental targets and collaborate on their decarbonization journey; and focusing on sustainable AI and technology solutions.
While we plan to continue these actions, our ability to achieve our near- and long-term goals remains challenging. Our emissions may increase as our business grows and evolves to meet our clients' needs, including driving reinvention with AI, data and technology, and as we continue to collaborate with clients in their locations.
Additionally, our progress may be impacted by the availability and cost of low- or zero- carbon energy sources and technologies, and the ability of our suppliers to reduce their emissions and harness new technologies.
