Examining the impact of GHG accounting principles

Abstract Clearly defined principles are essential elements of GHG accounting and reporting guidelines, protocols, and standards to address the unavoidable expert judgments that must be applied to address ambiguities in these documents. The IPCC guidelines identify transparency, accuracy, completeness, (time series) consistency, and comparability as its foundational data quality principles. The principles of conservativeness, relevance, and comparability see varied use across major GHG accounting references. These differences in principles, especially with respect to the principle of comparability, indicate there are underlying problems with many GHG accounting protocols and standards now heavily referenced and applied.
