This paper proposes a strict, science-based methodology for measuring corporate compliance with the Paris Agreement's climate goals. The authors argue that existing methodologies lack key features such as a common base year and consistent alignment with Paris-aligned decarbonization pathways. They introduce two necessary conditions and four operationalization requirements for a Paris-compliant emissions allocation methodology. Applying their method to electric utility and cement companies, they find that most are not currently compliant, highlighting the urgency of action and significant financial risks associated with inaction.
