During the production of Christmas trees, biomass is built up in the form of needles, branches, trunks and roots, which involves the absorption of CO2 from the atmosphere. In fact, 15-18 kg of CO2 is bound up in each felled ready-for-sale Christmas tree of 2 meters. In addition, for every tree, 4-5 kg of CO2 is bound up in the roots in the soil after a 10-year rotation.
Mechanical cleaning requires many crossings with various tools. In addition to high CO2 emissions, mechanical cleaning leads to higher nutrient leaching. Therefore, greenhouse gas emissions are reduced through moderate chemical cleaning under the certification scheme, Sustainable Christmas Trees.
Finally, cleared areas are replanted to ensure the continuous retention of carbon in the soil.
