The WRI/GHG protocol is currently scoping to deliver a standard methodology to quantify and report avoided emissions of products. So a company can calculate avoided emissions for goods and services.
Several companies already report avoided emissions on a corporate and company level. Several guidances for industries are available.
The DFGE follows the principle of physical emissions. Offering a calculation for the real physical emissions and a clear and separate calculation for any avoided emissins or green energy activities. The DFGE developed a gross/net methodology to allow companies to be fully compliant with any current standards thus been able to show their activities in terms of avoided emissions. For both – corporate and product emission calculations.
The Green House Gas Protocol is currently analyzing the stakeholders and started a survey. Further information can be found here.
