GHG Protocol resignation raises governance pressure

GHG Protocol is facing renewed scrutiny after a member of its independent standards board resigned and accused the carbon accounting standard setter of governance failures, bias, and lack of transparency.

The resignation concerns Danny Cullenward, a senior fellow at the Kleinman Center for Energy Policy and a member of GHG Protocol’s Independent Standards Board. The complaint centred in part on the protocol’s approach to forest carbon accounting.

GHG Protocol supplies widely used greenhouse gas accounting standards and guidance for companies and other organisations. Its frameworks sit behind a large share of corporate emissions reporting, climate target setting, supplier disclosure, and sustainability assurance work.

Carbon accounting has become part of financial, regulatory, procurement, and governance systems. Companies use emissions data to set targets, assess suppliers, support green finance, make public claims, and respond to investors. If the standard setting process is seen as weak, contested, or too exposed to industry pressure, the credibility of downstream disclosures can be affected.

Cullenward had previously published a governance case study through the Kleinman Center, describing GHG Protocol as a leading technical standard for corporate emissions reporting and arguing that its governance structure should be strengthened as it becomes more consequential in public policy. The report noted that the protocol operates as a joint initiative of the World Resources Institute and the World Business Council for Sustainable Development.

GHG Protocol has said on its governance page that it remains committed to a robust multi-stakeholder process and that its governance model has been integral to its success over the past 25 years. The organisation’s Independent Standards Board was established as part of a governance structure intended to support standard setting, review, and approval of normative documentation.

The resignation adds pressure at a sensitive point for sustainability reporting. Companies are already managing overlapping requirements and expectations from the International Sustainability Standards Board, the EU’s reporting framework, UK transition plan expectations, investor questionnaires, lenders, procurement teams, and voluntary climate initiatives.

Carbon accounting determines how companies calculate Scope 1, Scope 2, and Scope 3 emissions; how they account for land-sector activity; how they treat removals; and how they communicate progress against net-zero targets. Small methodological decisions can change reported emissions profiles, capital allocation, and stakeholder perception.

Scrutiny of ESG claims has already contributed to a rise in greenhushing among companies cautious about public sustainability messaging. Governance disputes around major reporting standards add another layer of caution. Claims based on disputed or poorly understood accounting methods may create reputational and regulatory exposure.

Forest carbon accounting and removals are especially difficult. Companies are increasingly interested in nature-based carbon claims, land-sector removals, and offset-linked strategies, but permanence, monitoring, double-counting, leakage, and equivalence remain longstanding challenges. Standard setters are under pressure to produce rules that are practical enough for companies to use while robust enough to withstand scientific and regulatory scrutiny.

Boards and audit committees will need to treat carbon data with the same seriousness as other business-critical metrics. That means asking how emissions are calculated, which standards are used, where judgements sit, whether external assurance is appropriate, and how changes to standards could affect reported performance.

The resignation does not invalidate GHG Protocol’s role, but it does underline the importance of governance in climate infrastructure. Standards that sit behind company disclosures need transparent processes, balanced representation, conflict management, and clear technical decision-making.

Companies should understand which GHG Protocol standards they rely on, whether upcoming revisions could affect reporting, and how sensitive climate claims are to accounting assumptions. As carbon reporting becomes more embedded in business decision-making, confidence in the rules behind the numbers will carry increasing weight.
