Carbon-Free Chronicles March 2026: The essential round-up of news and reports relating to hourly transparency
March was a month of accelerating signals. Major investors are calling for a fundamental update to Scope 2 accounting and the EU's Carbon Border Adjustment Mechanism entered its full compliance phase. The direction of travel is consistent: clean energy claims need to be grounded in physical reality, matched by time and location. Here is what has been on our radar this month.

What we're hosting
Next-gen Electricity Procurement: co-hosted by Granular Energy and CMS
- Join us on 24 April 2026 at the CMS offices in London for a morning of panel discussions on the future of clean energy procurement in the UK.
- We have speakers confirmed from CMS, Good Energy, LG Energy Group, Modo Energy, TEM, TotalEnergies, VodafoneThree, VPI, and others.
- The three sessions will cover the GHG Protocol Scope 2 revision and its implications for hourly matching, next-gen PPA structures and portfolio management in a high-renewables market, and the debate around Community Energy and Licence Exempt Supply in the UK.
- Event details:
09:00 Registration
09:30 Event begins - 3 panels
12:00 Closing remarks & informal networking lunch - Places are filling up! Register here (free event).
What we're reading
Major investors push the GHG Protocol to update Scope 2 rules
- A coalition of investors managing over $1.2 trillion in assets has signed an open letter calling current Scope 2 electricity accounting rules "no longer fit for purpose", urging the GHG Protocol to require hourly matching and physical deliverability for clean energy claims.
- Investors say they currently cannot tell which companies are genuinely buying clean electricity at the right time and place, which means capital is being misallocated to companies with green claims that do not reflect physical reality.
- The letter adds significant financial weight to the GHG Protocol revision process, which is expected to introduce hourly matching and deliverability requirements for large energy consumers.

The European Commission proposes extending CBAM
- The EU's Carbon Border Adjustment Mechanism entered its full compliance phase on 1 January 2026, requiring importers of carbon-intensive goods into the EU to report embedded emissions and purchase CBAM certificates.
- In March, the European Commission proposed extending CBAM's scope to cover downstream products (things like car parts, domestic appliances, construction equipment, power transformers and cables) and to introduce stronger anti-circumvention measures, closing loopholes that had allowed goods to be processed through third countries to avoid the carbon cost.
- For energy buyers, CBAM reinforces the case for clean energy traceability: the mechanism already includes an hourly matching requirement for electricity used in green hydrogen production, and the expanded scope signals the EU's direction of travel towards granular, verified emissions accounting across supply chains.

New US framework for clearer electricity disclosure
- The Center for Resource Solutions' Clean Energy Accounting Project (CEAP) has released new best practice guidance for how utilities, electricity suppliers and regulators in the US should communicate electricity sources and greenhouse gas emissions to customers.
- The guidance calls for product-specific labels rather than utility-wide averages, reporting based on the attributes customers are actually entitled to claim, clear treatment of RECs and other energy attribute certificates, and state policy requirements.
- The underlying problem: disclosure practices vary widely across US electricity markets, making it difficult for customers to compare products or verify the claims attached to their purchases. This guidance offers a practical path to more consistent, comparable and consumer-friendly disclosure.
- For anyone working in clean energy procurement, this is a useful reference point as the pressure for standardised, credible disclosure grows on both sides of the Atlantic.
- Read the full guidance here.
EU data centre sustainability label: promising but incomplete
- The European Commission proposed the Data Centre sustainability label with a public consultation open until April 23.
- They are requiring 15-minute granular GO matching within the same bidding zone, closing cross-border greenwashing loopholes. However, PPA rules remain vague and should be aligned.
- The label misses a major opportunity on grid flexibility: even modest data centre demand response could meaningfully support grid integration, as US hyperscalers are already demonstrating.
- Read the full initiative here.
The PPA market is evolving in different directions
- Dominique Hischier, VP Editorial & Analysis at Pexapark, joined Luca Pedretti on a podcast to unpack how structural price volatility, curtailment, and the rise of BESS are reshaping clean energy revenues and routes to market.
- The structure of corporate power purchase agreements is shifting in response to changing market conditions, with risk allocation, contract length, and offtake flexibility all under pressure.
- Suppliers and buyers are navigating a tension between the desire for long-term price certainty and the reality of a more volatile, geopolitically exposed wholesale market.
- Flexibility in contract design, including provisions for partial offtake and volume adjustment, is increasingly being seen as a feature rather than a compromise.
