What is Renewable energy guarantee of origin (YEK-G)?

An electronic certificate proving that electricity was generated from renewable sources, traded through the YEK-G system operated by EPİAŞ.

By acquiring YEK-G certificates for the electricity they consume, companies can report lower Scope 2 emissions under the market-based method. The certificates must relate to the same period and market as consumption and be cancelled.
