The NBS’s long-term goal is to achieve a sustainable operational model. To fulfil this target, it is gradually reducing greenhouse gas emissions from its operations and offsetting residual emissions by supporting carbon sequestration projects (the process of long-term capture of CO2 from the atmosphere and its storage in ecosystems, the world’s oceans, soil, or in special reservoirs). It also ensures the rational use of energy resources. In 2025, the NBS fleet was expanded to include 1 electric vehicle and 2 hybrid vehicles. Several measures were also implemented to improve the building’s thermal insulation and increase its energy efficiency. More detailed information on the NBS’s carbon footprint is available on a dedicated subpage.
