Carbon-Free Chronicles October 2025: The essential round up of news and reports relating to hourly transparency

What we’re reading

Public consultation for GHG Protocol Scope 2 revisions opened

• The Greenhouse Gas Protocol (GHG Protocol) now opened the public consultations. One focuses on updates to the Scope 2 Guidance (2015) which addresses inventory accounting, while the other seeks feedback on consequential accounting methods for estimating avoided emissions from electricity-sector actions.
• The consultations are open until December 19, and market players are invited to submit their feedback. Read more about how to contribute on their blog, or watch the recording of their webinar here.
• The Financial Times highlights that the proposed Scope 2 revisions could make it harder for some companies to maintain “100 % renewable” claims under stricter accounting rules, as the new guidance would require renewable generation to be time- and location-matched with consumption. However, there are positive signs from the industry, Google and AstraZeneca have backed “24/7” hourly-matching and localised approach to clean energy investments, a principle Granular Energy has long championed through our hourly transparency approach.
• We see the proposed changes to Scope 2 of the GHG Protocol’s consultation as a pivotal step towards increasing integrity in carbon accounting systems, and encouraging full grid decarbonisation. We encourage everyone to participate in the GHG Protocol consultation and make your voice heard!

Finland issues its first renewable hydrogen Guarantees of Origin

• In spring 2025, Gasgrid inaugurated Finland’s first industrial-scale green hydrogen production plant in Harjavalta, where hydrogen is produced with clean renewable energy. Now they celebrate the issuance of Finland’s first-ever guarantees of origin for hydrogen.
• This development strengthens traceability and credibility for clean-gas production, supporting Finland’s and Europe’s carbon neutrality goals and signalling readiness to expand guarantees of origin to other clean gases such as synthetic methane and biogas.

Matched launched the Clean Power Index, showing how much renewable power UK suppliers deliver, hour by hour

• Matched uses public data to calculate how much renewable energy UK suppliers provide, hour-by-hour. Their index highlights the challenges of the current system of annual matching, where summer electricity can be used in winter, all while following the rules.
• The Clean Power Index shows that over their entire portfolio, Good Energy has an 88% hourly matching score, outscoring Bryt (78%) and Drax (77%).
• Good Energy has an hourly matching tariff powered by Granular. While Matched looks at overall matching, we work with suppliers such as Good Energy to go into finer details and analyse hourly matching down to the consumer level.

TransitionZero finds 24/7 carbon-free electricity could deliver major cost and emissions benefits in Japan and Singapore

• TransitionZero analysed how 24/7 carbon-free electricity (CFE)could affect grid planners and corporate buyers, looking at Japan’s power system with an open source model. The results show that shifting from annual matching of clean energy to hourly 24/7CFE procurement, Japan can achieve about 90% hourly matching at costs below recent wholesale market prices, and doing so would yield annual fuel savings of about USD 1.84 billion for the system. Read the full analysis here.
• In another study, they analysed the potential for hourly-matched “24/7 carbon-free electricity (CFE)” procurement in Singapore, modelling a scenario where commercial and industrial buyers shift from annual clean-energy matching to real-time hour-by-hour matching. The modelling found that achieving a ~70% hourly CFE score by 2030 could reduce system capital investments for participating C&I consumers by about USD 47 million compared to annual matching, while delivering at least USD 185 million per year in fuel savings for the broader system. At higher shares (90% and above) the model shows that system-wide benefits continue to accumulate, through increased fuel savings, emissions reductions and improved grid flexibility, even as corporate incremental capital costs begin to rise.

Eurocham white paper recognises hourly as key to clean energy procurement in Asia

• The Eurocham Singapore white paper highlights hourly matching as a critical solution for renewable energy procurement, helping identify clean energy availability gaps and encouraging investment in storage, flexible demand, and procuring diverse renewables.
• The report notes that 24/7 CFE is expanding rapidly across Asia, with examples like Tokyo Metro’s hourly-matched supply using Granular Energy’s platform, and policy shifts in Taiwan and Australia enabling time-stamped energy certificates.
• As frameworks such as the Greenhouse Gas Protocol and Climate Group’s 24/7 CFE Coalition evolve, Eurocham positions hourly sourcing as essential for companies aiming to lead in emissions reduction, grid resilience, and innovation.

What we’re writing (and saying)

Hourly matching in practice: getting newcomers up to speed on hourly matching

• We continue to explain the world of hourly matching in our blog series. We aim to elucidate hourly matching to those discovering the concept ahead of the changes to the GHG Protocol’s scope 2 emissions guidance. The following articles are out now: Part 1: What is hourly matching and what does it mean for your business? Part 2: What is a high matching score? Part 3: How can you do hourly matching with monthly certificates?
• Follow us on LinkedIn for the final publication: how are businesses getting started.

Granular Energy expands EnergyTag accreditation globally

• After becoming an accredited issuer of Granular Certificates under EnergyTag last August for Europe and the UK, we have now expanded our coverage globally.
• With the EnergyTag accreditation we can:

1. Issue verified hourly GCs in regions lacking official hourly EACs, allowing energy buyers and sellers to participate in the 24/7 CFE transition globally.
2. Retrofit existing contracts, from PPAs to green tariffs, with time-stamped certificates that meet EnergyTag standards.
3. Enable compliance and leadership in sustainability claims, helping corporates align with upcoming regulatory shifts and investor scrutiny.

Granular Energy and Fairster launch partnership for greater transparency through efficient HKN management

• We’re excited to announce our partnership with fairster. Energie gGmbH, a fast-growing German energy supplier committed to fairness and transparency. With Granular Energy’s platform, Fairster can now streamline the management of Guarantees of Origin (HKN) - from portfolio management to customer allocation and cancellations in the HKNR - reducing manual work while ensuring greater transparency for end customers.
