The invention relates to a filler material (4) consisting of vegetable charcoal (2) filled into bags / sacks / shipping tray fabrics (3) for filling voids between a transported item and the surrounding parcel, package or other shipping systems, such as pallets, with the aim of ensuring damage-free transport of the transported item. This filler is biodiversity-enhancing (from 2024 onwards) because each unit of biochar produced is allocated to a corresponding unit of biomass within a balancing group. This biomass is biodiversity-enhancing because it is virtually free of synthetic substances, allowing the resulting biochar to receive the feed-quality biochar certificate. This natural growth pattern promotes the establishment of biodiversity in its environment. Since only biomass growth from the date of patent filing onwards can be recorded in the corresponding balancing group, the application title includes a reference to the year 2024 and subsequent years. This filler is climate-positive without compensation, as it already binds more carbon than is released during transport. A prerequisite for climate positivity is ensuring a defined storage of the biochar after shipment, e.g. as a soil improver, as a feed additive for livestock farming, etc. The filler (4) can also exert its emission-compensating effect in the form of molded shells which consist of the negative counterpart of a transported good.
