Carbon-Free Chronicles September 2025: The essential round up of news and reports relating to 24/7 clean energy

What we’re reading (and hearing)

Public consultation for GHG Protocol Scope 2 revisions coming up in October

• The Greenhouse Gas Protocol (GHG Protocol) will launch a public consultation mid October on Scope 2 Guidance revisions. This is an invitation to all market participants to review and share their thoughts on the suggested revisions. Once available, we will post the link in this newsletter so we encourage you to loop back and share your comments. The key novelties when it comes to granularity are:
  
  - Location based methodology will require the use of the most precise location-based emission factor available.
  - Market based methodology will require that certificates be matched on an hourly basis and sourced from generation deemed deliverable.
  - Read the summary of the proposed updates.
  
  This is a rare opportunity to help shape the future of corporate emissions accounting. Join the GHG Protocol consultation in October to make your voice heard.
• In parallel, the two leading frameworks for corporate emissions accounting, the Independent Standards Organisation (ISO) and the GHGP, have announced a strategic partnership to deliver a single, globally aligned set of rules for greenhouse gas reporting. The collaboration will merge ISO’s environmental management standards with GHG Protocol’s corporate, Scope 2, and Scope 3 methodologies, reducing reporting fragmentation and improving comparability across markets.

Carbon accounting experts promote hourly matching and dismiss the current use of 100% renewable claims

• Tune into the conversation with Laurent Segalen (GHG Protocol Task Force v1) and Killian Daly (EnergyTag, GHGP Scope 2 TWG), as they unpack the future of carbon accounting, power procurement, and the push toward 24/7 CFE.
• They highlight the problem that companies can still claim to be “100% renewable” based on solar power at night, while running on fossil power in reality. This misrepresents progress, misallocates capital, and ignores the need for more renewables, storage, demand response, and clean firm power.
• But change is coming, listen to their podcast on #spotify https://lnkd.in/ditGthT or #applepodcast https://lnkd.in/dhTv48S.

Call to action for all suppliers and retailers offering tariffs with hourly matching

• Since the launch of the 24/7 Carbon-Free Coalition by Climate Group, many electricity consumers have been seeking suppliers who can provide hourly matched tariffs that meet the Coalition’s Technical Criteria.
• To support this, Baringa, EnergyTag, and Granular Energy are gathering information from energy suppliers and retailers to curate a list of providers offering tariffs with hourly matching transparency. This list will be made available on the EnergyTag and Climate Group 24/7 Carbon-Free Coalition websites.
• Do you offer hourly matching tariffs or are considering to launch one? Complete the short survey by October 10th: Supplier Survey Link.

Hourly Matching in Practice: a mini-series to help newcomers to hourly matching get up to speed

• We kicked off our Hourly Matching in Practice mini-series last week. This series aims to help newcomers to hourly matching quickly get up to speed and ahead of the changes to the GHG Protocol’s scope 2 emissions guidance. Over the next week’s we’ll share the following articles: 1) What is hourly matching and what does it mean for your business? 2) What is a good matching score? 3) How can hourly matching work without hourly certificates? 4) How and why are businesses getting started with hourly matching?
• Follow us on LinkedIn to get up to speed!

Granular Energy is becoming an ESNA, powering the future of exempt supply

• Granular Energy takes another step toward operationalising hourly tracking by becoming an Exempt Supply Notification Agent in the UK. ESNAs are authorised to notify energy volumes directly into the UK’s Balancing and Settlement Code.
• This capability enables generators and consumers to participate in market settlement while maintaining traceability. By becoming an ESNA, suppliers and intermediaries will soon have access to a streamlined, settlement-ready service for exempt supply, with none of the complexity of building internal systems from scratch.
• Are you looking for an ESNA partner? Get in touch. You can read more here.

Partnership Announcement: Granular Energy & Matched Energy

• Our partnership with Matched Energy strengthens the UK ecosystem for 24/7 CFE. Together, we’re combining transparency and infrastructure: Matched Energy brings supplier benchmarking, while Granular delivers the platform for hourly traceability. Together we’re setting the stage for accountable clean energy products at scale.
