Carbon Credit PDD

A PDD is the foundational document submitted to a carbon credit standard (such as Verra VCS or Gold Standard) to register a GHG mitigation project. It describes the project boundary, selected methodology, baseline scenario, additionality argument, monitoring plan, and the quantification of expected emission reductions.

Verra VCS is the largest voluntary carbon market standard by credit volume and accepts a broad range of project types including REDD+, improved forest management, and industrial methane. Gold Standard (GS4GG) places stronger emphasis on co-benefits and SDG contributions and is widely used for cookstoves, community energy, and climate+development projects. A project can only be registered under one standard at a time.

Additionality shows the project would not have happened without carbon finance. Standard tools include the VCS Additionality Tool, CDM Tool 01 (investment analysis, barrier analysis, common practice analysis), or methodology-specific performance benchmarks. The analysis must prove the project is not business-as-usual in its context.

Leakage is an unintended increase in GHG emissions outside the project boundary caused by the project activity (e.g. deforestation displaced to a neighboring area). Leakage must be quantified and subtracted from the gross emission reductions. Net issuable credits = baseline emissions minus project emissions minus leakage.

Under VCS, non-AFOLU projects typically get a 10-year crediting period renewable twice (30 years total) or a single 20-year fixed period. AFOLU projects get 20-100 years. Gold Standard generally offers 5-year crediting periods renewable up to 7 times. The choice affects both credit volume and revalidation timing.

You need the project boundary, applicable methodology, baseline scenario parameters (grid emission factor, fuel consumption, reference deforestation rate, etc.), project activity data, and leakage assumptions. Formist can extract these from feasibility studies and methodology documents to produce a first estimate of annual and total issuable credits.
