Guarantees of Origin (GOs) offer a transparent way to verify renewable energy sources, helping businesses showcase sustainability and prevent fraud in energy reporting.
Guarantees of Origin (GOs) are certifications that ensure transparency regarding the origin of consumed energy. Introduced in 2011 alongside the EU Renewable Energy Directive, each GO represents 1 MWh of energy and verifies that the energy source is 100% renewable. Currently, Guarantees of Origin are a voluntary measure in many regions but serve a crucial role in building trust in renewable energy.
Verifying Guarantees of Origin is essential to prevent fraudulent reporting and ensure that investors, clients, and regulatory bodies are accurately informed about renewable energy use. Reliable GOs contribute to credible sustainability claims, vital for companies striving to demonstrate environmental responsibility.
One of the primary benefits of purchasing Guarantees of Origin is the transparency it provides businesses. With mandatory reporting directives increasingly in force, GOs verify that energy is genuinely from renewable sources. This transparency helps businesses fulfill regulatory requirements and supports sustainability reporting.
Guarantees of Origin play a key role in combating energy fraud. As verified certificates, they ensure energy source traceability, making it challenging for organisations to misrepresent their energy origins. This accountability helps build trust with customers and stakeholders.
Many companies are choosing partners based on shared sustainability values. By using Guarantees of Origin, businesses can ensure their energy sources align with carbon-conscious goals. Verified GOs provide an accurate reflection of a company’s carbon footprint, enabling better alignment with sustainability objectives and attracting like-minded partners.
To ensure the legitimacy of Guarantees of Origin, they must be verified through official channels:
Authorised organisations like the European Energy Certificate System (EECS), the Association of Issuing Bodies (AIB), and Ofgem validate GOs. These bodies verify certificates independently of the energy source, ensuring that GOs accurately represent renewable energy sources.
GOs use digital tracking to provide detailed information on energy origins. Each certificate includes data that traces the energy back to the originating power plant, down to the exact MWh, creating transparency in energy sourcing.
To prevent fraudulent certificates, GOs undergo regular audits by independent third parties. Ofgem, for example, conducts audits on renewable energy plants as part of its role administering the Renewables Obligation (RO), Renewable Electricity Guarantees of Origin (REGO), and Feed-in Tariffs (FIT) schemes.
Innovative technologies such as Blockchain and digital ledgers are revolutionising the verification of Guarantees of Origin, increasing transparency and security.
Blockchain enhances traceability by removing intermediaries like brokers and utility providers, linking energy use to its verified origin. This approach leverages smart contracts to automate tracking, ensuring authenticity and fair energy pricing.
Digital ledger systems store energy source data in a transparent and accessible network. This digitalisation helps all stakeholders view energy origins, contributing to a secure and reliable verification process.
The European Energy Certificate System (EECS), developed by the AIB, provides a standardised framework for Guarantee of Origin verification, motivating businesses to transition to renewable energy. This framework has influenced regions globally, establishing verification methods that enable access to certified renewable energy.
The use and transferability of Guarantees of Origin vary based on regional policies and certification standards. Below is an overview of how GOs are implemented across different regions:
In the EU, Guarantees of Origin can be transferred internationally if both countries are EU members and AIB participants. Certain countries, like Romania, have adopted additional national standards to facilitate these transfers.
In North America, Guarantees of Origin are known as Renewable Energy Certificates (RECs). Like GOs, RECs represent 1 MWh of renewable energy and are tracked regionally through 10 registries across the USA and Canada. Each registry has specific rules regarding certificate import and export.
Outside of Europe and North America, regions like Vietnam, Singapore, Thailand, and Japan have developed their own versions of renewable certificates. While varying by region, solar and wind energy sources are the most commonly certified, with hydro, biomass, and geothermal certifications on the rise.
Guarantees of Origin provide a critical framework for renewable energy verification, ensuring transparency and accountability across global markets. From supporting sustainability goals to preventing fraud, GOs and similar certification systems are essential for businesses and governments dedicated to a carbon-neutral future. As technology advances, GOs continue to evolve, reinforcing the credibility and adoption of renewable energy worldwide.
