The main difference from the 'classic' requirements of the SBP standards is the requirement for the pellet producer to develop its own set of requirements for the suppliers of feedstock based on the NL SDE+ sustainability criteria, but developed taking into account the specifics of the regions of feedstock origin – round wood. The requirements must include quite an extensive list of obligations which includes the preservation of high value forest landscapes, crucial natural habitats, establishment and implementation of measures to manage natural forest carbon stocks, prohibition for significant transformations of forest landscapes, compulsory reforestation, decreasing the impact to water and soil, etc. Following the developed requirements, the logging enterprises which make up the Region-Les Company Group have implemented all requirements into their daily activities. The specialists of Region-Les LLC have confirmed this fact in their internal supplier audits.
