The biomethane certification process can appear complicated due to the existence of multiple certificates serving different objectives. There are Guarantees of Origin (GOs), Proofs of Sustainability (PoS), and in some countries, national certificates. Understanding the roles and differences of each certificate can be challenging, especially for those who are new to the market. In this session, expert speakers will introduce the different biomethane attribute certificates and explain the practical aspects of how to use them. The panel will discuss how market participants and regulators could further develop this important sector.
