(AP) – Carbon credits are often associated withutilities and other big fuel-burning industries. But now, the MaineState Housing Authority is getting into the act. MaineHousing is now one step away from being able to sell carbonemission reductions from its home weatherization program. Director Dale McCormick says MaineHousing’s method for measuringcarbon savings from weatherization has been approved by anindependent, third-party validator. McCormick’s confident Maine’sapproach will achieve a second, final validation. When that happens, MaineHousing should be able to sell thecarbon savings created by weatherizing homes and apartments, andthen use the revenue to weatherize more homes.
