Driving Alignment Across Greenhouse Gas Reporting Frameworks: Recommendations for Consistent and Transparent Disclosure

Abstract

The rapid emergence of multiple greenhouse gas accounting frameworks, both mandatory and voluntary, has complicated corporate emissions reporting, creating barriers to effective climate accountability. This study addresses the question: How can consistency and impact across regulated greenhouse gas accounting frameworks be achieved in response to varying mandatory and voluntary standards? Through a comparative analysis of industries including Automotive, Retail, and Technology, alongside insights from regulatory bodies and standard setters, this research identifies significant reporting challenges such as inconsistent methodologies, difficulties in capturing accurate Scope 3 emissions data, and regulatory fragmentation across U.S. federal, state, and international standards. Findings reveal behavioral patterns among companies, such as "perfectionism paralysis," where stringent requirements for precise data delay necessary emissions reduction actions. Additionally, corporations selectively disclose favorable emissions data to manage regulatory and reputational risks, hindering transparency. To mitigate these issues, three targeted policy solutions are proposed:

Encouraging transparency about uncertainties and emissions exclusions to build credibility and stakeholder trust. Advocating for regulatory "safe harbor" protections to reduce barriers and risks associated with disclosing imperfect Scope 3 data. Recommending phased federal mandates for comprehensive Scope 3 emissions reporting, balancing accuracy with practical implementation constraints.

These recommendations aim to streamline emissions reporting frameworks, improve data comparability across sectors, and support meaningful corporate action towards decarbonization.
