European harmonisation of construction products provides a uniform expression of performance aspects relevant for essential characteristics coming from notified technical building regulations of the EU Member States. Since the current regulation has been in force for over seven years, this study evaluates further possibilities of its evolution, including a more efficient approach to implementing environmental sustainability aspects. The provided research is based on qualitative analysis of the past and current legislation, official documents, related guidance, judgements, scientific articles and the author’s practical experience coming from participation in the European committees, organisations and standardisation activities. Various legislative techniques and regulatory tools that could be potentially used to review the Construction Products Regulation are analysed and compared with regards to their impact on the inclusion of environmental sustainability principles. Therefore, the objective of this research is to provide substantive grounds that can be directly or indirectly used in the policymaking processes on the European and national level.
