No. 121: Toward Decision-Useful Carbon Information

Year: 2023
Type: Working Paper
Open Science:


Companies are increasingly viewed as crucial drivers for timely decarbonization. Current accounting practices for greenhouse gas (GHG) emissions, however, often leave corporate carbon disclosures and abatement obscured. Here I introduce a taxonomy for assuring the quality of corporate carbon information. Analog to financial accounting standards, information on a firm’s GHG emissions is to be decision-useful to stakeholders. That is, it is relevant and faithfully represents the actual changes in atmospheric GHG associated with a firm’s economic activity. Applying the taxonomy, I find that information prepared under the widely used Greenhouse Gas Protocol generally fails to represent a firm’s GHG emissions faithfully. Yet, if certain conditions prevailed, it would faithfully represent a share of those emissions. My findings highlight the need for revising the GHG Protocol as well as recently proposed carbon disclosure mandates and standards, which seek to produce decision-useful information but have also adopted the GHG Protocol.
