REDD+ Under VM0048: How Verra's Consolidated Methodology and Jurisdictional Baselines Are Changing Forest Carbon Verification
In 2023, a Guardian/Die Zeit investigation and the West et al. paper in Science put REDD+ credibility on trial. The charge was straightforward: project-level baselines were inflating deforestation estimates and, with them, credit volumes. Verra's answer was VM0048, a complete methodological reset launched on 27 November 2023. VM0048 replaced the legacy family of REDD+ methodologies, including VM0006, VM0009, VM0015, and VM0037, with a single consolidated approach. The core shift is significant. Baselines are no longer set by individual projects. They're set at the jurisdictional level, using independently produced deforestation risk maps. For anyone involved in REDD+ verification or nature-based solutions crediting, this changes practically everything about how forest carbon projects are developed, validated, and verified. Here's what the new architecture looks like in practice. How VM0048 Works: Jurisdictional Baselines in Practice Under VM0048, activity data and deforesta...
