      "excerpt": "For each wetland type and country, the potential carbon storage loss is defined as the difference between the undisturbed baseline and the disturbance-adjusted stock, expressed in CO2-equivalent (CO2-eq) units. Summed across wetland classes and countries, these estimates indicate a disturbance-associated stock difference observed under 2018 conditions, rather than a realized emission trajectory over a specified time period. Land-use disturbances correspond to potential losses of 0.8–4.9 Gt CO2-eq, equivalent to roughly 10–11% of the mean soil carbon storage pool in European wetlands. All estimates represent 2018 conditions and quantify potential carbon storage losses associated with contemporary land-use disturbance, rather than annual greenhouse-gas emission rates, and are restricted to natural and seminatural open wetlands, excluding historically lost wetlands, forested wetlands and heavily drained peatlands.",

Searched the full Nature article section on disturbance, carbon loss and restoration targets for omitted time range, denominator/baseline, sampling, jurisdiction, and interpretation. The counted anchor omitted material scope qualifiers that the full passage states: the stock difference is observed under 2018 conditions, is not a realized trajectory over a specified period or an annual greenhouse-gas emission rate, and is restricted to natural and seminatural open wetlands excluding historically lost, forested, and heavily drained wetlands."
