Although peatland restoration is widely promoted to recover carbon sinks and avoid emissions, recent empirical studies reveal that rewetted sites can temporarily act as net carbon sources or increase short-term warming due to methane emissions and complex carbon balances.

The retrieved literature shows a division between long-term theoretical and broad-scale benefits of peatland restoration (acting as carbon sinks and avoiding emissions) and short-to-medium term empirical findings showing that rewetted boreal forests or recently rewetted minerogenic fens can initially act as carbon or greenhouse gas sources due to elevated methane emissions or delayed vegetation recovery. Therefore, the claim is contested depending on the timeframe and specific ecosystem type.
