GHG Protocol Scope 2 Guidance Overhaul: What’s Changing
The Greenhouse Gas Protocol is undertaking a comprehensive revision of its 2015 Scope 2 Guidance, one of the most widely used frameworks for reporting indirect emissions from purchased electricity. The proposed changes , which include hourly energy matching, more granular emission factors, and tighter location-based vs. market-based accounting rules , have sparked intense debate across the sustainability reporting landscape.
On February 20, 2026, the European Financial Reporting Advisory Group (EFRAG) published a formal position paper responding to the GHG Protocol’s public consultation, calling for a “balanced and cost-effective approach” to the proposed modifications. This response carries significant weight: EFRAG develops the European Sustainability Reporting Standards (ESRS) that underpin the EU’s Corporate Sustainability Reporting Directive (CSRD), meaning any misalignment between the GHG Protocol and ESRS could create compliance headaches for thousands of European companies.
For organizations already navigating the complexities of carbon footprint reporting, these developments demand close attention.
What the GHG Protocol Is Proposing
The current public consultation covers several ambitious changes to Scope 2 accounting:
Hourly Energy Matching
Rather than annual or monthly matching of renewable energy procurement to consumption, the proposed guidance would encourage , and potentially require , hourly granularity. This means companies would need to demonstrate that their renewable energy certificates (RECs) or power purchase agreements (PPAs) match their actual electricity consumption on an hour-by-hour basis.
More Precise Emission Factors
The revisions propose using more localized and time-specific emission factors, moving away from national annual averages toward grid-level, potentially hourly, emission intensities. While this increases accuracy, it also dramatically increases data collection complexity.
Revised Market-Based Accounting
The relationship between location-based and market-based methods is being reconsidered, with proposals to tighten the criteria for what qualifies as a valid market-based instrument and how residual mix calculations should work.
Cross-Standard Consistency
The GHG Protocol is also working to eliminate inconsistencies across its various standards and guidance documents, ensuring that Scope 2 accounting aligns with the Corporate Standard, Scope 3 Standard, and the new Land Sector and Removals Standard.
EFRAG’s Five Key Concerns
EFRAG’s response is notably cautious. While supporting the goal of improved comparability in emissions data, the advisory group raises five substantive concerns that companies should understand:
1. Complexity vs. Practicality
EFRAG explicitly states that “the consultation materials and survey are lengthy and, at points, overly complex.” This matters because complexity in standards translates directly to implementation cost. Companies already struggling with CSRD compliance may find additional Scope 2 complexity prohibitive.
2. Cost-Benefit Assessment
Before any ambitious proposals advance , particularly hourly matching and precise emission factor calculations , EFRAG demands rigorous cost-benefit analysis. The question is straightforward: does the incremental accuracy justify the additional reporting burden? For many mid-sized companies, the answer may be no.
3. Longer Consultation Windows
EFRAG recommends minimum 120-day feedback periods for future consultations, reflecting the GHG Protocol’s expanding regulatory significance. As more jurisdictions adopt GHG Protocol-aligned mandatory reporting, changes to its guidance effectively become regulatory changes , and should be treated with corresponding deliberation.
4. Concrete Draft Language
Rather than consulting on conceptual frameworks, EFRAG urges the GHG Protocol to base consultations on specific draft amendments. This would allow stakeholders to assess actual implementation implications rather than theoretical possibilities.
5. Jurisdictional Flexibility
Perhaps most critically, EFRAG advocates for a principles-based approach that permits jurisdictional flexibility. Pedro Faria, EFRAG’s Environmental Director, emphasized that “changes should be proportionate, clearly justified by user benefit, and capable of being implemented in diverse regulatory and electricity market contexts without creating unintended distortions.”
This is a direct signal that the EU expects to maintain its own technical specifications within the ESRS framework, even as it aligns with GHG Protocol principles.
COP30 Context: The Bigger Picture
These Scope 2 discussions unfold against a larger backdrop. In February 2026, GHG Protocol Steering Committee Chair Geraldine Matchett published a letter framing 2026 as a critical year for global carbon accounting harmonization. The COP30 Action Agenda gave the GHG Protocol and ISO a joint mandate to lead harmonization efforts, with several parallel workstreams:
- Scope 2 Guidance revision (currently in public consultation)
- Product-level GHG accounting standard (joint development with ISO)
- Land Sector and Removals Standard (newly launched)
- Scope 3 updates (under development)
The letter emphasizes that Scope 3 represents the “largest transformation opportunity” since emissions span entire value chains , suggesting that Scope 2 changes are just the beginning of a broader overhaul.
What Companies Should Do Now
Short Term (Q1–Q2 2026)
- Audit your Scope 2 methodology: Understand whether you use location-based, market-based, or dual reporting. Map your current data sources and emission factors.
- Assess hourly data readiness: Can your energy management systems provide hourly consumption data? If not, start conversations with your utility providers and data collection tools.
- Review your renewable energy instruments: Ensure your RECs, PPAs, and Guarantees of Origin meet current quality criteria , tighter rules are coming.
Medium Term (Q3 2026 – Q1 2027)
- Monitor the final guidance: The GHG Protocol will analyze all consultation feedback and publish revised guidance. Track updates through your sustainability reporting platform.
- Align ESRS and GHG Protocol reporting: If you report under CSRD, map how the ESRS E1 climate standard references GHG Protocol methodology. Any divergence will need to be managed. Check our CSRD Resource Hub for guidance.
- Budget for implementation: If hourly matching becomes required, budget for the technology infrastructure and data management changes needed.
Strategic Considerations
Companies should view these changes as an opportunity to strengthen their carbon accounting infrastructure. Organizations using automated sustainability platforms are better positioned to adapt, since software-driven data collection can accommodate new granularity requirements without proportional increases in manual effort.
The key takeaway from EFRAG’s response is that proportionality will be a guiding principle in how these changes are implemented within the EU. Companies should prepare for change, but avoid over-investing in compliance approaches that may be simplified before final adoption.
Looking Ahead
The Scope 2 revision process will continue through 2026, with the GHG Protocol expected to publish updated guidance by late 2026 or early 2027. Meanwhile, EFRAG will continue developing ESRS implementation guidance that accounts for any GHG Protocol changes.
For sustainability teams, the message is clear: the standards are evolving, and the companies that invest in robust, flexible data infrastructure now will be best positioned to comply with whatever final requirements emerge.
