Cool Co2mmute Associate-inspired program that partners Interface with associates to target and reduce the GHG (greenhouse gas) emissions from their daily commutes. Associates calculate and offset their own carbon emissions from commuting. Interface pays half the cost of the offset purchases, making the net average cost to associates $12 each year to be cool drivers. Cool Fuel Interface’s Cool Fuel™ program calculates and offsets the carbon emissions from company cars. Since its inception in 2002, the program has offset more than 11,500 tonnes of CO2, the equivalent of avoiding emissions from one million gallons of gasoline.
