On May 2002, Vitoria Airport was awarded the ISO -14001 environmental management certificate by AENOR (Spanish Association of Regulation and Certification). This certification internationally recognises and validates the effort and actions carried out by the airport concerning the environment.

The environmental management system adopted by the airport includes, among other measures, the treatment of solid waste with its separation and evaluation, the treatment of dangerous waste, the increase in the flow rate of the purifier and the improvements established in this purifier, together with the regulation and capturing of surface water for irrigation. Challenges and aims have also been established in relation with the reduction of the consumption and recycling of paper, perishable computing material, etc.
