| 22 | )))|(% style="width:730px" %)The annual carbon sequestration is a commonly used indicator of the global climate regulation ecosystem service of different vegetation types. The storing and sequestration of carbon (dioxide) can be quantified and monitored relatively easily, and enable spatial and temporal comparisons of the capacities of different nature-based solutions. The amount of sequestered carbon is directly proportional to biomass growth, for which a sort of biomass functions and equations are available in the fields of forestry and agricultural sciences (McPherson et al. 2016, USDA 2015). The carbon content is around 50% of the amount of biomass. This kind of knowledge is available mainly for trees which can be considered as good indicators of the whole ecosystem’s capacity in areas with lack of data (as they have an outstanding role in carbon sequestration and storage). Natural and management-related mortality of biomass (and life of products if relevant) should be considered to get a total carbon balance of the investigated NBS. | ||
