On his first day in the Oval Office, President Biden signed an executive order recommitting the U.S. to the Paris Agreement. With new targets set to curb carbon emissions and build a greener, more resilient future, design firms and contractors are now tasked with helping owners reshape what it means to be green in the age of COVID-19.
Companies are ranked according to revenue for construction or design services generated in 2019 from projects that have been registered with or certified by a third-party organization that sets standards for measuring a building’s or facility's environmental impact, energy efficiency or carbon footprint. Such groups include the U.S. Green Building Council (USGBC) and the Green Building Initiative. The volume of revenue is measured in ($) millions. Some markets may not add up to 100% due to rounding. Revenue from construction management on a fee-only basis is not included.
