Combines CICES + MAES indicators + scientifically trustworthy quantitative metrics commonly used in enviromental impact assessment. Metrics are calculated using open source data (mainly Landsat and Sentinel). The methodology considers direct negative impacts on natural capital, differentiating between reversible and irreversible (restorable) impacts. Natural capital net loss is obtained from ecosystem services variation between a baseline state and a post-construction or post-operation phase. Natural Capital changes are expressed in equivalent hectares. Same methodology can be used to quantify positive impacts derived from restoration and conservation actions.
