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.
