We define our core value of sustainability as the creation or enhancement of environmental, economic, and social balance, as realized through client deliverables, business activities, employee actions, and community engagement. Backed by empowered teams, we implement these principles and best practices in corporate operations and customer solutions to address environmental risk and minimize our carbon footprint.

Greenhouse Gas Emissions

We acknowledge the risks that climate change poses to the natural environment, human health, and economy and believe that we have a responsibility to help mitigate its effects. We have set a target to reduce our absolute Scope 1 and Scope 2 greenhouse gas emissions by 20% by 2025 compared to a 2019 baseline. This target was developed to be in line with the 2 degree scenario defined by the Paris Agreement.

We partner with property owners in our leased facilities to implement energy-saving lighting and HVAC systems. In addition, our flexible work options allow employees to work remotely on a part-time or full-time basis, which reduces the need for office space. Energy consumption in our leased facilities has decreased by 32% since 2019, in large part due to a cumulative 20% reduction in our leased office area.

Facilities Water Consumption (cubic meters estimated)


We partner with property owners in our leased facilities to adopt water conserving measured wherever possible to reduce impacts of our leased office facilities . In 2021 we began a broader-based collection of water use data for our office operations. In 2022 we were able to obtain data covering approximately 52% of our leased footprint. Total water use for the entire footprint was calculated by extrapolating based on our total area of leased home-office spaces. Water usage for 2020 is estimated using 2021 rates of consumption per SF leased real estate.

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. In 2022 we recycled or repurposed 30 metric tonnes of e-waste and recycled 118 metric tonnes of paper waste in our North American operations.

Guiding Principles

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.
