In a significant move for energy market transparency and sustainability, Cleanworld, enmacc, Parameta Solutions, and General Index (GX) have announced a partnership to launch standardized, trusted price indexes for Guarantees of Origin (GOs) across Europe.
This joint initiative introduces Europe's first set of spot and historical prices for GOs, covering key renewable technologies - Hydro, Wind, Solar, and Nuclear - across multiple vintages (2023–2029). These indexes reflect real market activity, sourced from a combination of Cleanworld’s market intelligence, enmacc’s trading data, Parameta Solutions' independent market data, and published through the pricing infrastructure capabilities of GX.
The result is a trusted index system designed to bring clarity and consistency to a fast-evolving and often opaque market. For the first time corporate buyers, analysts, and traders can rely on standardized prices to evaluate GO contracts, track market movements, and manage compliance risk.
Neil Bradford, CEO of General Index, said of the partnership: "This partnership represents a major step forward in bringing transparency and standardization to the Guarantees of Origin market. By combining deep trading data, sustainability expertise, and benchmark pricing capabilities, we’re delivering the first credible, independent price indexes for GOs.”
Aron Simon, Managing Director, Cleanworld, added: "Cleanworld has been dedicated to providing transparency and insight in renewable energy markets for over 15 years. By partnering with General Index, we are equipping the market with robust benchmarks and data-driven tools that enable the creation of meaningful analysis and innovative products. We are excited to support this innovative, new product in market transparency and look forward to continued collaboration to accelerate the development of the market for guarantees of origin and other environmental commodities."
Jens Hartmann, CEO of enmacc, commented: "At enmacc, our mission is to bring transparency and efficiency to energy trading. Contributing trading data from our leading OTC energy market venue to these new GO price indexes is a natural extension of that commitment. This partnership finally provides the market with the reliable, standardized benchmarks it needs to truly unlock the potential of GOs for corporate buyers, traders, and the broader renewable energy transition."
Victor Laurent, Head of Energy & Commodities Data Products for Parameta Solutions, shared: "We are thrilled to drive enhanced clarity and confident decision-making in the Guarantees of Origin market. With a substantial depth of data, rigorously-validated pricing, and deep renewables expertise, Parameta's GO data provides the critical foundation to this cutting-edge benchmark."
