Use our calculators to discover your own CO2 emissions, or choose to offset any of the average CO2 footprints below. In addition to our "help build" carbon offsets, we offer "vintage" carbon offsets that support the ongoing operation of high quality CO2 reducing projects that meet our strict criteria for "additionality." Because these projects were built in reliance on the prospect of carbon offsets revenues, your purchase helps build the market for clean energy and other carbon offset projects, and can stimulate more investments in building these valuable projects. Vintage offsets are referenced to the year that the verified emission reductions are produced.You can support the Paraiso Hydroelectric Project in Brazil or the Des Plaines Landfill Gas Collection and Destruction Project in Illinois, USA. These offsets are third-party verified as detailed in their project descriptions.
