97% of Germany’s peatlands have been drained, mostly for agricultural use. This results in oxidation processes - peatlands contribute 7% of Germany’s CO2 emissions. Re-wetting stops these emissions. "re:wet" coordinates this and simplifies the necessary surveying. With the "peat:lab", farmers determine terrain heights, water levels, peat thickness and vegetation composition. All data is collected in a digital twin. In this way, re-wetting measures can be planned, tendered and monitored, greenhouse gas emissions modeled, certified and traded, and biomass distributed.
