by Rebecca Walker — December 29, 2010—Deloitte, one of the Big Four accounting and consulting firms, announced that it has acquired two sustainability consulting firms, ClearCarbon Consulting and Domani Sustainability Consulting.

ClearCarbon and its principal, Kyle Tanger, have focused on measuring and mitigating greenhouse gas footprints, while Domani and its founder and CEO, Will Sarni, have focused on water, energy and resource reduction. Sarni has been a moderator and speaker at FORTUNE’s Brainstorm Green.

Sustainability is “one of our top growth areas,” said Chris Park, a principal at Deloitte Consulting who leads the firm’s sustainability services. He’s seeing demand across industry sectors, including the federal government, consumer products, retailers and traditional oil, gas, utility and energy companies. “Sustainability will be a major driver of business transformation in upcoming years,” he said.

Deloitte will add 30 to 40 professionals to its staff as a result of the acquisition. ClearCarbon was based in Arlington, Va., while Domani was based in Denver.
