Opportunities and Challenges of Using VCS for Forest-Carbon Payments in Developing Countries

Abstract The Verified Carbon Standard (VCS, administered by Verra) has been a dominant standard for issuing voluntary carbon credits (VCUs) from land-based activities including REDD+-type avoided-deforestation projects. For many developing countries, VCS-certified credits present an opportunity to attract private finance for forest protection, deliver local benefits, and pilot jurisdictional nesting with national REDD+ systems. However, academic evaluations and practitioner reviews between 2015–2025 identify recurring challenges: inflated baselines and over-crediting risks, permanence and leakage uncertainties, uneven safeguards and benefit-sharing outcomes, high transaction costs and capacity gaps, and difficulties reconciling project-level credits with national accounting. This review synthesizes the evidence, highlights the practical opportunities and pitfalls for developing-country contexts, and offers pragmatic recommendations to maximize the climate, social and governance benefits of using VCS for forest-carbon finance.
