This chart compares the estimated generation of carbon reductions (i.e. carbon offsets) from each of our Help Build™ carbon projects to their actual production through December 2011.
We are proud to report that the long-term performance of our Help Build™ carbon project portfolio is 106.8%. In 2011, our portfolio performed at 101.1%. That means that our projects have, to date, offset more CO2 emissions than the amount our customers contracted for.
Several projects, like the Greensburg Wind Farm, are performing better than expected. Others have experienced maintenance issues. The Wray wind turbine resumed operation partway through the year, following repairs to the generator; it is now at normal production. The underperformances of the Iowa Wind Project and Wewoka Biogas Project were due to typical start up issues. Performance in 2012, not yet verified, shows them operating at expected levels.
We calculate each project’s production according to the methods established by internationally recognized carbon standards, including the Verified Carbon Standard and Climate Action Reserve.
There are distinct approaches for each project type. Within project types, such as agricultural methane, the calculations are highly specific and nuanced to reflect variances in the way the material is managed and handled. The difference between the rigor required of a certified forestry project and a simple tree-planting program, for example, is like the difference between the sun and the moon.
All NativeEnergy carbon projects that you can help build receive third party validation as meeting the requirements of the carbon standard. All carbon offsets are verified by an expert independent third party following their generation over time.
