In 2016, Gensler signed the Paris Pledge for Action at the COP21 conference, pledging to reduce carbon emissions to limit climate change to less than 2 degrees Celsius. Gensler's “Impact Through Design” report, launched in 2016, explores strategies for architecture and design to play a greater role in global climate change strategy and mitigation, reinforcing this commitment to sustainability with the firm's subsequent “Impact by Design” reports in 2017 and 2018.
