How much does a carbon offset cost and what is the CO₂ benefit?

Each monthly offset costs just $4, yet balances the effect of 500 pounds of carbon dioxide (CO₂) on the atmosphere. For Indiana residents, 500 pounds of CO₂ is equivalent to 250 kilowatt hours (kWh) of energy use. The average Duke Energy residential customer in Indiana uses 1,000 kWh of energy per month. So for $16 per month (or four carbon offsets), you could offset your home’s monthly energy use and carbon emissions.

Enroll to purchase monthly carbon offsets before Sept. 30, 2010, and Duke Energy will plant a tree in your name to help offset even more of your energy usage.
