What is the science behind Peat Bog restoration as a CO2 capture mechanism? How is effectiveness of actual projects typically measured?/Evidence Gaps and Debates

This page is part of the research tree for [[../|Peat Bog restoration as a CO₂ capture mechanism]]. See the [[../Research Plan|Research Plan]] for the full research approach.

Planned Content

This page will map what is not yet known, what is contested, and where research is heading:

Methane trade-off: at what timescale does CO₂ saving outweigh CH₄ increase? (GWP100 vs GWP20 debate)
Permanence: for how long is restored peatland carbon storage secure given fire risk and climate change impacts on water tables?
DOC and aquatic carbon: does restoration reduce fluvial carbon loss, and how significant is this in the overall carbon balance?
Additionality and leakage in carbon credit contexts
Scaling from individual sites to landscape/national estimates
Effectiveness of different restoration techniques — lack of controlled trials
Social and economic dimensions — cost-effectiveness and land-use trade-offs

Key sources to consult: Günther et al. (2020), Evans et al. (2021), UK Committee on Climate Change — peatland in the UK carbon budgets and net zero pathway, recent review articles and horizon-scan papers.
