Designing high-integrity REDD+ projects aligned with ICVCM Core Carbon Principles, from baseline scenario to verified issuance.
The voluntary carbon market faces a credibility crisis. Studies have documented systematic over-crediting, weak baseline scenarios, and inadequate leakage accounting. Our client needed a project design that would withstand scrutiny.
Our client sought to develop a 45,000-hectare REDD+ project in the Brazilian Amazon with a target of 12.5 Mt CO₂e over 30 years. The project needed to align with Verra VCS methodology VM0047, Gold Standard requirements, and the new ICVCM Core Carbon Principles[4].
We applied Angelsen et al.'s (2017) results-based payment framework[1] and addressed the over-crediting critiques raised by West et al. (2020)[2] and Badgley et al. (2021)[3] by designing a conservative baseline with robust uncertainty quantification.
West et al. (2020) found that forest-based carbon offsets may not deliver promised climate benefits without stronger MRV. Badgley et al. (2021) documented systematic over-crediting in California's forest offset program.
Conservative baseline (10th percentile reference region), 3.2% leakage buffer, 20% uncertainty deduction, and full ICVCM CCP alignment.
From baseline scenario to verified carbon credit issuance, every phase is designed for transparency, conservativeness, and auditability.
Historical deforestation trend (2008–2022) projected forward using reference region data at the 10th percentile to ensure conservativeness.
Activity data from forest patrols, community monitoring, and remote sensing-based disturbance detection.
Market leakage (1.8%) and activity-shifting leakage (1.4%) quantified and deducted from net credits.
Combined uncertainty propagated through Monte Carlo simulation; 20% deduction applied to net GHG benefits.
Project design document validated by a VVB accredited under the VCS Program and Gold Standard.
Annual monitoring reports verified by a VVB; credits issued only after successful verification.
