The GCC has published the GCC Nature-based Solutions (NbS) Tool for Estimating GHG Emissions from Oxidation and Burning of Peat (GCCTA004 v1.0). The tool provides a structured and scientifically robust approach to quantifying greenhouse gas (GHG) emissions from drained peatlands, caused by oxidation, and fires.
Context and Importance
Peatlands play an important role in the global carbon cycle as carbon sinks. However, when degraded through drainage they release large amounts of greenhouse gases through oxidation and burning thus significantly contributing to climate change. This new tool addresses the need for scientifically based standardized methods to estimate these emissions, aiding project developers in implementing NbS and sustainable land management practices.
Key Features of the Tool
- Comprehensive Emissions Accounting: The tool calculates GHG emissions of CO₂, CO, and CH₄ from peat oxidation and fires in drained peatlands.
- Baseline and Project Scenarios: The tool is implementable in baseline and project scenarios.
- Data-Driven Monitoring: Includes stratification requirements, default values, and monitoring guidelines for precise emissions estimation.
- Applicability: Tailored for methodologies addressing climate impacts of peatland drainage and restoration/rewetting activities.
Methodology Overview
The tool adopts a detailed and systematic approach:
- Stratification and classification of peatland areas based on peat or water table depth, fire history, and vegetation.
- Use default or project-specific values to calculate GHG emissions under baseline and project conditions.
- Clear guidelines for monitoring peat rewetting activities to estimate their impact on emission reductions.
Adoption and Availability
The GCC Regulatory Committee officially adopted this tool on January 8, 2025, following a global stakeholder consultation held between November 6 and December 5, 2024.
The tool is available for project developers seeking to quantify and reduce emissions from drained peatlands, providing a reliable framework for implementing effective nature-based solutions.
