The company is participating in initiatives that seek to reduce carbon emissions

For more than a decade now, OHL is taking part in initiatives that focus on generating awareness amongst its stakeholders and society in general about the importance of actively fighting against climate change, whilst also incorporating various methodologies into its business model that encourage energy efficiency in its infrastructures and construction projects. These procedures help reduce carbon dioxide emissions, to include other steps for the recycling, management, transformation and reuse of construction material.

OHL’s continuous commitment to a low-carbon economy includes quantifying and verifying its greenhouse gas (GHG) activities to reduce emissions in the company’s operations, as well as investing in sustainability projects to compensate such emissions. Furthermore, it follows initiatives promoted by international organizations, seeking to reduce carbon consumption in the business world, to include a registration of a carbon print at the Spanish Office for Climate Change, thanks to which a “Calculo” [“Calculated”] seal has been obtained from such organization, which validates carbon print calculations according to the methodology and principles established by the Ministry for Ecological Transition. Furthermore, this authority has promoted an Agreement for a Circular Economy, to which OHL is party.

We have helped recover natural ecosystems, such as characteristic  Lake Owens (California, USA), with measures seeking to protect local plants and animals, along with the management and control of protected species. All of this is part of a project to mitigate dust emissions, focusing on a surface area of nearly 7 million m2.

This practice has been recognized by prestigious international authorities, such as the U.S. Green Building Council, an organization that promotes sustainability in building design and construction, which has granted a LEED® (Leadership in Energy & Environmental Design)  certification to 34 of our unique construction projects, in its various categories: Platinum, Gold, Silver and Leed.

ODS 11


European Mink

In Navarre (Spain), we have participated in restoring the habitat of the European mink further to the Canal de Navarra project. This collaboration has helped stress the importance of establishing preventive and restoration measures, to reduce the impact suffered by this protected species habitat, returning it to its natural state, or even improving it.
