Climate gain
Trees and shrubs absorb CO2 from the air through photosynthesis and store it as carbon (C) in their above- and below-ground biomass. CO2 is also stored in the soil and litter of forests and landscape plants.
In an average Dutch forest, for example, approximately 790 tons of CO2 per hectare is stored in biomass, litter and soil. The forests in the Netherlands currently account for 60% of the total CO2 fixation.
