How Rewetting Peatlands Could Slash Warming‑Driven CO₂ Emissions

Rewetting Peatlands: A Climate Lever

Rewetting peatlands is emerging as a low‑cost, high‑impact strategy to blunt the surge of CO₂ released from drained wetlands. Scientists estimate that drained peatlands currently spew ↓ 5 Gt of carbon annually, a figure that dwarfs many industrial sources.

Field trials across Indonesia, Finland and Canada reveal that restored sites can achieve a ↑ 30% cut in emissions within five years, while also rebuilding biodiversity.

“If we act now, rewetting could offset a sizable share of the remaining carbon budget,” said Dr. Lina Mäkinen, a peatland specialist at Reuters.

Policy makers are weighing incentives, noting that the upfront investment is modest compared with the long‑term climate payoff. Scaling these projects will require coordinated funding streams and clear land‑use guidelines.
