AENOR N Sustainable Mark

The AENOR N mark is the first and only Sustainability certification in Spain. It was designed to drive the transformation of industry sectors towards a greater commitment to sustainability, focusing on three aspects: environmental, social and governance matters.

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.

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.
