In the course of the implementation of the Green Deal, the EU's regulatory framework expanded significantly. RoHS Directive, REACH and CLP regulations are undergoing revision processes, addressing the Chemical Strategy for Sustainability, while new initiatives such as the Sustainable Product Initiative (SPI) and relevant delegated acts addressing the European Circular Economy Plan are piling up.
The scope of this contribution is to highlight the impact of current and upcoming chemical regulatory amendments on the space industry, focusing on EU REACH but also global legislative measures, such as POPs/Stockholm convention and others. There are also other initiatives related to the broader sustainability goals of the European space community, which may also have an effect on the materials selection of future missions.
Special attention is dedicated to reliance on Bisphenol A and its derivatives, per- and polyfluoro alkyl substances (PFAS, including fluoropolymers), D4, D5 and D6 cyclic siloxanes, and other chemicals essential for the production of advanced polymeric materials relevant for many space applications. Potential alternatives to PFAS-based materials, their technological maturity and performance in space environments will be discussed.
The oral presentation will introduce the work of the Materials and Processes Technology Board (MPTB, the initiative in the frame of European Space Component Coordination), which is monitoring the evolution in materials' standardisation, obsolescence, material shortages, and R&D activities in the context of the European space sector.

Note: This abstract is intended to support oral presentation and panel discussions.
