Verified Emission Reductions - are environmental offsets from projects that reduce Greenhouse Gas emissions (carbon dioxide or methane.) Carbon emissions have proven to be harmful to our environment and are remitted from cars, airplanes, manufacturing plants, power plants and other industrial entities.

A VER is a reduction of greenhouse gases equivalent to one metric tonne (2,205 lbs) of carbon dioxide or methane below a baseline which would have occurred in the absence of the activity creating the offset. Corporations and organizations unable to reach their carbon reduction targets through direct reductions of their own emissions can purchase VERs to balance, or offset, their environmental impact. For VERs, a physical transfer of title pursuant to a contract or attestation typically occurs via a electronic transfer of ownership on the applicable registry, such as those maintained by the Climate Action Reserve, the Voluntary Carbon Standard, the American Carbon Registry, or the Chicago Climate Exchange.
