Sustainability is one of our core values. Backed by empowered teams, we implement best practices in corporate operations and solutions to address environmental risk and minimize our carbon footprint.

Greenhouse Gas Emissions

We commit to reduce absolute Scope 1 and Scope 2 greenhouse gas emissions by 20% by 2025 from a 2019 baseline. The science-based target helps us to reduce our impact on our planet and aligns with a 2◦C scenario.

Normalized GHG Emissions
(MT CO2e/$M Revenue)


We partner with property owners in our leased office spaces to implement energy-saving lighting and HVAC system retrofits. Our flexible work options allow employees to work from home offices on a part-time or full-time basis instead of commuting to an office, reducing the need for office space and associated energy and emissions. Our energy comes from a variety of sources dependent on location.

Facilities Energy Consumption (mmBTU)

Water Consumption (1,000 Gallons)


We work with property owners to adopt water-conservation measures whenever possible to reduce impacts of our leased office facilities. Water consumption metrics represent consumption at our Centerville, VA headquarters. More information can be found in our GRI Disclosures.

Waste Diversion

While our office recycling programs vary by location, we have corporate programs for recycling waste paper and office electronics in a safe and secure manner.

We know that successful environmental performance must be grounded in effective policies and procedures. We continuously review and update our policies, procedures, training, and solutions to reflect best practices in the industry.
