Ashley Jones, Communications Specialist at GHG Protocol, sat down with Danny Cullenward, Senior Fellow at the Kleinman Center for Energy Policy at the University of Pennsylvania and member of Greenhouse Gas Protocol’s Independent Standards Board (ISB) to discuss how his interdisciplinary background in law, economics, and climate science informs his work. 

Summary 

Following recommendations from the Scope 2 Technical Working Group and approval by the GHG Protocol Independent Standards Board to progress to public consultation, revisions to the Scope 2 Guidance (2015) will be shared through a 60-day public consultation period, starting in October. In the proposed revisions, the structure of the updated scope 2 reporting framework would remain the same, including a continuation of the dual reporting requirement for both the location-based and market-based methods. Changes to the location-based method (e.g., updated emission factor hierarchy, requirement to use the most precise emission factors accessible, a new definition of accessible data) and market-based method (e.g., hourly matching requirement, deliverability requirement, new emission factor requirements) prioritize improved accuracy, greater transparency, and provide more comparability inventory values for use by external disclosure frameworks and initiatives. The proposed revisions also introduce several measures to improve the implementation feasibility of the updates (e.g., load profiles for hourly matching, exemption thresholds to hourly matching for smaller organizations, a legacy clause for existing contracts, and a multiyear phased implementation). This is the first of several communications in a series leading up to and continuing through the Scope 2 public consultation. These updates will help explain what is being proposed and why, providing additional context for stakeholder engagement. Future blog posts will delve into hourly and deliverability requirements and provide guidance on how to participate in the upcoming consultation process.

On September 9, 2025 GHG Protocol and the International Organization for Standardization (ISO) announced a ground-breaking partnership, aimed at reducing fragmentation in the GHG accounting landscape. This new partnership drives forward an ambition of harmonization and co-development, resulting in a  common global language for emissions measurement and reporting and thus simplifying the task at hand for companies, consultants, verifiers, auditors, conformity assessment bodies, and other third parties (e.g., trainers and software companies). It also aligns with growing calls for harmonization, including most recently by the B7 community, which is tasked with consolidating the interests of the business community and developing concrete and actionable recommendations to the G7 leadership. 

• A new era begins in carbon accounting as ISO and GHG Protocol agree to harmonize their existing portfolios of GHG standards and to co-develop new standards for GHG emissions measurement and reporting
• Until now, GHG standards have been developed separately with varying scopes and verification guidance. The new ISO–GHG Protocol partnership, announced today, represents a fundamental shift toward integration and co-development, enabling users to rely on a coherent framework and reducing potential confusion in the market
• The partnership will produce a common global language for emissions accounting, which will accelerate progress towards decarbonization
• The development of combined, credible standards for GHG emissions terminology, measurement, and reporting provides a long-awaited, trusted solution for companies, investors, verifiers, auditors and policymakers, and aligns with recent calls for harmonization by both government and companies.

GHG Protocol is currently in the process of updating its corporate suite of standards and guidance, including its Scope 2 Guidance (2015). In the decade since the Scope 2 Guidance was published, there have been significant changes within the GHG emissions accounting and reporting ecosystem, including the development of both voluntary and mandatory disclosure frameworks and the increase in adoption of net-zero emissions targets.
