Abstract
A key factor undermining the credibility of carbon offsets is the evaluation of project baselines and their impact. The ex ante scenarios constructed by project developers in accordance with rules set by certification schemes have been challenged by ex post evaluations from scientists, who frequently document cases of credit allocations that overestimate the actual emission reductions. Increasing credibility requires methodologies that reliably measure project outcomes and prevent overcrediting—an objective that ex post evaluations may be well suited to achieve. We explore how systematic ex post evaluations could restore credibility to certification schemes in the voluntary carbon market. Inaccuracies in the evaluation of project impacts, even under ex ante scenarios, can cause overestimation or underestimation of carbon offsets. This study shows the potential of systematic ex post evaluations to enhance the credibility of voluntary carbon market schemes.
期刊介绍:
Nature Sustainability aims to facilitate cross-disciplinary dialogues and bring together research fields that contribute to understanding how we organize our lives in a finite world and the impacts of our actions.
Nature Sustainability will not only publish fundamental research but also significant investigations into policies and solutions for ensuring human well-being now and in the future.Its ultimate goal is to address the greatest challenges of our time.
