Colorado-based SunOne Solutions creates projects such as wind farms or forests that help the environment, then sells the credits to electric utilities and other businesses seeking to offset their carbon emissions. Company President John Hodges writes that SunOne used to build as many projects as it could, figuring that more carbon credits equaled more value. But then the recession hit, factories slowed and emissions declined -- along with the value of carbon credits. Realizing that companies preferred to invest their green dollars close to home, SunOne targeted fewer projects in closer proximity to industrial polluters, Hodges writes. The move helped to win industry accolades and avoid layoffs at the 10-person firm.
