New accolade for the N Mark

To obtain this mark, AENOR analyses a minimum of 20 indicators based on the rigorous quality certification of products, AENOR N mark, which has had a major role in the market for decades, adding sustainability criteria to meet society's new requirements.

After completing the certification process, the result is a numerical index that represents the sustainable commitment in a clear and comparable manner. This index also allows studying the performance over time, as it is renewed every year, and fosters a continuous improvement effort in the sector.

Certification process for the AENOR N Sustainable Mark


 What is the AENOR N Mark for sustainability?

Based on the AENOR N mark certification requested by companies voluntarily, and which submits products to a complete examination with the objective of guaranteeing the performance of construction materials, the AENOR N mark for sustainability adds to these requirements the European sustainable building criteria level(s).

Developers, builders, associations and consumers trust that their products meet the quality, safety and durability requirements laid down in the standards, in addition to the mandatory CE marking for products subject to European directives or regulations.

This Sustainability certification is a key element in manufacturers' processes of adapting to the guidelines of European strategies in terms of sustainability, and it is in line with the requirements for accessing Next Generation European Funds.


The first AENOR N mark for Sustainability certificates were carried out in June 2022 at 14 factories in the Spanish steel sector, confirming their commitment to an ESG approach:(Environmental, Social and Good Governance), which have been followed by the remaining sectors involved in building construction.

The AENOR N mark for certified products:

  • It is a symbol awarded by AENOR as an independent entity and a leaderin certification.
  • It is a mark that is recognised and highly regarded by all society, in the public and private sectors, and makes it easier to market more than 100,000 certified products worldwide.
  • It represents a guarantee that is particularly valuable for the end customer or user in the case of products not subject to said CE mark.
  • It supplies the market with products that exceed the basic requirements of the regulatory CE mark and the minimum quality standards. This is the case in certain sectors, such as low-voltage electrical devices in general (except for cables) and certain non-structural construction products, where the manufacturer itself declares compliance with the standards. This makes the voluntary product certification with the AENOR N mark even more meaningful, since the products are subjected to strict controls and tests before they are certified by AENOR.

To certify each product, AENOR develops a specific certification system, which establishes the requirements the product must comply with: standards and technical specifications, certification procedures (frequency of audits, inspections and tests) and specificities applicable to each product family.
