Guarantees of Origin (GOs)
Document renewable electricity consumption across Europe to reduce greenhouse gas emissions, achieve sustainability goals, and comply with environmental regulations.
What is a Guarantee of Origin?
Guarantees of Origin (GOs) are certificates used to track and document the consumption of renewable energy in Europe. Each GO represents 1 MWh of renewable energy and specifies how, where, and when that unit of energy was produced, allowing buyers to claim its environmental benefits — such as reduced emissions.
Ecohz has deep expertise in helping businesses source GOs and credibly report renewable energy use in every European country, while guiding them through an increasingly complex regulatory landscape.
