Regulation (EU) No. 305/2011 of the European Parliament and of the Council laying down harmonised conditions for the marketing of construction products and repealing Council Directive 89/106/EEC.

The rules of Member States require that construction works be designed and executed so as not to endanger the safety of persons, domestic animals or property nor damage the environment. This Regulation establishes harmonized conditions for the marketing of construction products. The basic requirements for construction works set out in Annex I shall constitute the basis for the preparation of standardisation mandates and harmonized technical specifications. Obligations of economic operators (manufacturers, their representatives, importers and distributors) are laid down. Among other essential requirements, it is stipulated that the construction works must be designed and built in such a way that they will not have an exceedingly high impact, over their entire life cycle, on the environmental quality or on the climate during their construction, use and demolition. In particulat, they shall not result in the giving-off of toxic gas; the emissions of dangerous substances, volatile organic compounds (VOC), greenhouse gases or dangerous particles into indoor or outdoor air; the emission of dangerous radiation; the release of dangerous substances into ground water, marine waters, surface waters or soil; the release of dangerous substances into drinking water or substances which have an otherwise negative impact on drinking water; faulty discharge of waste water, emission of flue gases or faulty disposal of solid or liquid waste; dampness in parts of the construction works or on surfaces within the construction works. Further, the construction works must be designed, built and demolished in such a way that the use of natural resources is sustainable and in particular ensure the following: (a) reuse or recyclability of the construction works, their materials and parts after demolition; (b) durability of the construction works; (c) use of environmentally compatible raw and secondary materials in the construction works.
This Regulation does not affect the right of Member States to specify the requirements they deem necessary to ensure the protection of health, the environment and workers when using construction products.
