97% of Germany's peatlands have been drained - mostly for agricultural use. The resulting oxidation processes account for 7% of Germany's CO2 emissions. Rewetting stops these emissions. re:wet coordinates and simplifies the necessary surveying. With the peat:lab, farmers determine terrain heights, water levels, peat thickness and vegetation composition and store all data in a digital twin. In this way, rewetting measures can be planned, tendered and monitored, greenhouse gas emissions can be modeled, certified and traded, and biomass can be distributed.
