Our operations are strongly linked to natural resources and our business plays a key role in tackling biodiversity loss and degradation. We take a rigorous science-based approach and we work with nature in a progressive transformative way, going beyond traditional rehabilitation. 


At Holcim, we commit to making a measurable positive impact on biodiversity by 2030. Backed by science-based indicators on our active and non-active quarries, we help to protect natural ecosystems and the livelihoods of those in neighboring communities. We will achieve this by working in partnership with local stakeholders, who understand the local ecosystem, ensuring a positive contribution to biodiversity and the well-being of our societies.

  • We measure our biodiversity level baseline by implementing a scientific methodology called Biodiversity Indicator and Reporting System (BIRS), across all our quarries by 2024. This has been developed in partnership with International Union for Conservation of Nature (IUCN).
  • We are using the Integrated Biodiversity Assessment Tool (IBAT) to support us in prioritizing actions in high biodiversity areas. We will measure our biodiversity level again by 2030. A higher biodiversity index will demonstrate that we are on a positive trajectory

How we reach our commitments

Progressive transformative rehabilitation


We capitalize on natural processes, endemic species and local adaptation to take into account the wider landscape and conservation context. Some key actions include buffer zone optimization and, when relevant, creation of habitats not previously found on the site, like green corridors for wildlife connectivity and wetlands.

Our sites are rehabilitated in a progressive manner. In other words rehabilitation takes place simultaneously with extraction work — areas where extraction is finished are rehabilitated while work continues in other areas of the quarry.

Measuring positive biodiversity impact

We apply the mitigation hierarchy to prioritize and guide actions to enhance our positive biodiversity impact.

Mitigation hierarchy

We worked in partnership with the International Union for the Conservation of Nature (IUCN) to develop a methodology to measure our biodiversity level. This tool is called the Biodiversity Indicator Reporting System (BIRS). With BIRS we will define our biodiversity baseline and measure our biodiversity improvement over the years on our active and non-active quarries. BIRS assessment will allow us to better understand the challenges and opportunities we have at each site for enhancing biodiversity and improving ecosystem conditions. We will identify key actions, develop action plans and implement them to increase our biodiversity index.

Landscape approach

Our quarries and sites are an integral part of wider landscapes. They play an essential role in providing ecosystem services to people, including indigenous communities and vulnerable groups, as well as being the habitat of wildlife and flora. The landscapes cover important habitat types, from forests to grasslands and from deserts to wetlands.

We aim to become a leading voice in landscape protection beyond our own sites, participating in or leading multi-stakeholder collaboration. We work with all relevant stakeholders — from industrial sites to our suppliers (which usually are located in the same landscape) to agricultural producers and local communities.

Creating and executing on a common vision for biodiversity protection across our landscapes will include important local elements such as wildlife corridors and protection from natural hazards like fire or floods. It will be complemented by our approach to water stewardship and commitment to human rights and positive social impact. This will enable a holistic and inclusive view, resulting in a more sustainable landscape for all.

A pioneer in impact valuation

As a founding member of the Value Balancing Alliance, we developed a global Impact Measurement and Valuation standard for assessing and disclosing economic, social and environmental impacts in a monetized way within our own operations and suppliers.

Promoting good practices throughout the value chain

We work with suppliers identified as having a high environmental impact to demonstrate continuous improvement towards having a recognized environmental management system in place.

Embedding biodiversity into product innovation

We develop solutions that are focused on improving nature and bringing more of it into cities across our portfolio.

Bioactive concrete: preserving marine wildlife

Bioactive concrete is a solution that supports marine biodiversity by rehabilitating areas with damaged coastal ecosystems.

Elevate green roofing systems

Elevate roofing systems contain the urban heat island effect and enable green roofs which helps biodiversity thrive in cities.
