Six of Spain's most important engineering companies, and competitors in their field, have started up an interesting project that hopes to strengthen the presence of this sector in sustainable development. The Engineering and Sustainability Foundation has been promoted by SENER together with AYESA, EPTISA, EUROESTUDIOS, IBERINSA and TYPSA. Two of its objectives are to emphasize the role of technology as a motor of the society and the defense of the engineering companies as guarantors of sustainable development. This Foundation advocates for a new management model of infrastructure works in which the suitability of the project is valued based on the social interests. Also, a committee of experts with specialized representatives from each company has been organized to write up a white book of subjects related to sustainability.
