An open-source decentralised application (dApp) being developed by the Energy Web Foundation has already been tested on several sites. The application offers more granular data (about power ownership, location, time, and avoided marginal CO2 emissions for each kWh) while enabling direct, automated certificate of origin trading between renewable energy generators and buyers of any size (EWF, 2018). This allows consumers to have an enhanced ability to identify and procure from renewable energy assets with greater avoided marginal emissions potential.
