Abstract: A dynamic model simulating carbon dioxide (CO2) sequestration by plants embedded in a vertical greenery system (VGS) was developed. The aim of the model was to demonstrate the advantages, in terms of CO2 sequestration, obtained by installation of large vegetated wall surfaces in urban areas. The ability of various plants, tested separately or in a mixed-species set, to accumulate carbon in different compartments and moments of their life (plants, compost, soil and microbial biomass in soil) was quantified. The model simulates a series of processes, from planting and growth of herbaceous plants in the VGS to the end of their lives, when compost is produced from green residues and is added to agricultural soil. The amount of CO2 removed from the atmosphere is the portion finally stocked in the soil in the form of microbial biomass.
