Voluntary Carbon Markets & Offset Integrity Certification

The Voluntary Carbon Markets & Offset Integrity Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests voluntary carbon markets and offset integrity — how carbon credits are created, verified and retired, avoidance versus removal credits, additionality, permanence, leakage and baseline setting, registries and standards such as Verra and Gold Standard, the ICVCM Core Carbon Principles, VCMI claims, Article 6 and corresponding adjustments, nature-based and engineered removals, pricing and market structure, and avoiding greenwashing in offset claims — written to ICVCM, VCMI, Oxford Offsetting Principles and UNFCCC guidance for 2026 and 2027. Score 70% or more on its 20 questions to earn a verifiable Voluntary Carbon Markets & Offset Integrity certificate (SOA-VCMO). Every question is based on published standards and research — including Core Carbon Principles and Assessment Framework (Integrity Council for the Voluntary Carbon Market), Verified Carbon Standard program (Verra), Oxford Principles for Net Zero Aligned Carbon Offsetting (University of Oxford) — and each answer is explained with its source.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Market Foundations (Credit lifecycle, Avoidance and removal and Market structure); Integrity Principles (Additionality and baselines, Permanence and leakage and Core Carbon Principles); Standards, Policy and Article 6 (Registries and standards, Paris Agreement Article 6 and Corresponding adjustments); Buyers, Claims and Pricing (Corporate claims, Pricing and quality and Greenwashing risk).

A project is additional if the emission reductions or removals would not have happened without the revenue from carbon credits. Non-additional credits do not represent real climate benefit.

Avoidance credits come from preventing emissions that would otherwise occur, such as protecting a forest. Removal credits come from taking carbon dioxide out of the atmosphere, such as reforestation or direct air capture with storage.
