Peatland Emissions Calculator
Peatland Emissions Calculator – Estimate greenhouse gas emissions (CO₂, CH₄, N₂O in CO₂-eq) from peatlands based on IPCC scientific methodologies. This reliable tool helps landowners, researchers, and policymakers assess emissions from drained, intact, or rewetted peatlands.
Peatlands store vast carbon but release significant GHGs when drained. Use this Peatland Emissions Calculator to quantify annual emissions per hectare or total area, supporting conservation, rewetting projects, and climate reporting.
About the Peatland Emissions Calculator
This tool implements Tier 1 default emission factors from the 2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands, with refinements from later studies. It calculates CO₂ from peat oxidation (main driver in drained soils), CH₄ from anaerobic conditions (higher in wet/rewetted), and N₂O from drainage/fertilization. Results are in tonnes CO₂-equivalent (CO₂-eq) per year using GWP100 (CH₄=28, N₂O=265).
Importance of Peatland Emissions Tools
Peatlands cover ~3% of land but store ~30% of global soil carbon. Drainage for agriculture/forestry causes massive CO₂ release, contributing to climate change. Rewetting reduces CO₂ but increases CH₄ temporarily. Tools like this Peatland Emissions Calculator enable evidence-based decisions for restoration, carbon credits, and national inventories. Accurate estimation supports Paris Agreement goals and sustainable land use.
User Guidelines
1. Select climate zone (boreal/temperate/tropical affects defaults).
2. Choose peatland status: Intact/Undrained (natural low emissions), Drained (high CO₂), Rewetted (low CO₂, higher CH₄).
3. Select land use (influences factors, e.g., cropland higher N₂O).
4. Enter area (ha) for total emissions.
5. Optional: Mean water table depth (m below surface) – note only, as Tier 1 uses defaults.
Results update instantly. For site-specific accuracy, consult Tier 2/3 or measurements.
When and Why You Should Use This Tool
Use when planning peatland management, assessing restoration benefits, reporting emissions, or comparing scenarios (drain vs. rewet). Why? Peat degradation emits ~2 Gt CO₂-eq annually globally – more than aviation. Quantifying helps prioritize rewetting for climate mitigation, biodiversity, and flood control.
Purpose of the Peatland Emissions Calculator
To provide transparent, science-based estimates promoting peatland protection. Built for accessibility on websites like this, it raises awareness and supports action. Developed with reference to authentic sources including Peatland Emissions research and IPCC guidelines.

Peatlands are unique wetland ecosystems characterized by accumulation of organic matter (peat) under waterlogged, anaerobic conditions that slow decomposition. They represent one of Earth's largest terrestrial carbon stores, holding an estimated 500–600 Gt of carbon – twice the carbon in all forest biomass. However, human activities like drainage for agriculture, forestry, peat extraction, and urbanization have degraded vast areas, turning these carbon sinks into major GHG sources.
The primary gas from drained peatlands is CO₂, released via aerobic decomposition of exposed peat. CH₄ dominates in saturated conditions, produced by methanogenic microbes. N₂O arises from nitrification/denitrification, amplified by drainage and fertilizers. The IPCC Wetlands Supplement (2013) and 2019 Refinement provide default emission factors (EFs) by climate zone, nutrient status, and management – the basis here.
For drained temperate/boreal cropland: CO₂ EF ~10–40 t CO₂ ha⁻¹ yr⁻¹ (higher in tropical). Rewetting shifts to near-zero or negative CO₂ (uptake), but CH₄ rises to 100–300 kg ha⁻¹ yr⁻¹. Total CO₂-eq often drops dramatically post-rewetting, as CO₂ reduction outweighs CH₄ (despite higher GWP).
Why accurate tools matter: Peat emissions contribute significantly to national totals (e.g., in Indonesia, EU). Misestimation affects policy, carbon markets, and restoration funding. This Peatland Emissions Calculator democratizes access to IPCC science, aiding smallholders, NGOs, and governments.
Limitations: Tier 1 defaults are averages; site factors (water table, peat type, temperature) vary. For precision, use local data or models. Future updates may incorporate 2019 refinements or regional EFs.
In summary, peatland protection/rewetting offers high climate mitigation potential at low cost. Tools like this empower informed choices toward sustainable futures.
