2021 SUSTAINABILITY HIGHLIGHT REPORT: Forward As One ENVIRONMENT 11 In 2021, we achieved 100% renewable energy use across our offices in the U.S. and abroad through self-generation, RECs and carbon credits. OUR SUSTAINABILITY EFFORTS Highlights include: • Consolidating our real estate footprint, which will result in a reduction of more than 1,800 metric tons of GHGe annually. • Converting our headquarters campus from steam to hydronic heating, which will reduce our annual GHGe by 1,200 metric tons when completed in 2022. • Replacing the main Tower escalator with stairs at our headquarters campus in Hartford, Connecticut. This action yielded savings of nearly 12 metric tons of carbon emissions. Wooden steps were chosen instead of granite (which create more emissions to produce). The new stairwell also contributes to our well- being goals.
