Navigating Carbon Credits: A 20-Minute Dialogue

This course provides a technical overview of carbon credits as economic instruments for managing climate impact. It begins by defining a carbon credit as a tradable claim representing one metric ton of carbon dioxide equivalent. The material covers the economic principle of externality pricing and the functional distinctions between emissions reductions, removals, and avoided emissions. The discussion compares compliance markets, such as the European Union Emissions Trading System, with voluntary project-based markets. It examines how regulatory caps create scarcity in compliance systems while trust and verification drive value in voluntary offsets. Key mechanics, including the issuance, trading, and retirement of credits, are explained to show how these assets move through the global economy. The second half of the course focuses on risk management and strategic implementation. It outlines the four core integrity tests used to evaluate credit quality: additionality, permanence, leakage, and double counting. By comparing forestry-based storage with industrial projects, the course explains why low-quality credits present significant financial and reputational liabilities. Strategic topics include the mitigation hierarchy, which dictates that companies should prioritize direct reductions over offsetting. It introduces tools like marginal abatement cost analysis and internal carbon pricing to help organizations decide when to purchase credits for residual emissions. This framework ensures that carbon credits serve as a secondary tool within a credible climate strategy rather than a substitute for genuine operational changes.
