Biodiversity:
Target and performance

Fauna increase

The positive trend in biodiversity at our production sites results from implementing measures from our pioneering Biodiversity Action Plans and the dedication of our biodiversity ambassadors, who monitor key species like bees, birds, and butterflies. These species are essential indicators of urban ecosystem health and help measure the effectiveness of our efforts. This success demonstrates that small actions can significantly impact biodiversity.

Biodiversity ambassadors

The number of trained ambassadors showcases the community engagement we have created around the topic of biodiversity. These colleagues learned the importance of protecting nature and took positive actions with their own hands.

Tree planting

We are committed to promoting a healthier planet through reforestation projects and tree planting at our production sites and quarries, even in areas where tree planting is not required. Several countries have played a role in this initiative, with a special focus on long-term environmental impacts. In North America, large-scale projects have been particularly impactful. In 2024, over 50,000 trees were planted on 49 hectares of previously mined land, helping to prevent erosion and improve soil quality.

A notable example shows how the simple step from the Biodiversity Action Plan after its implementation has effectively contributed to the growth of fauna populations:

Belgium: First results from implementation of biodiversity measures

In the Seneffe plant in Belgium, where the grass around the site was kept short and often mowed, ecologists observed no bees during the baseline visit. However, by planting native flowers, we created a more attractive habitat for pollinators, increasing bee populations, including various species of bumblebees, butterflies, and birds.

Learning of the importance of biodiversity and how to protect it is not limited to the premises of our offices and production sites. We share this knowledge with other local stakeholders through events like the Biodiversity Day. By communicating the relevance of biodiversity to other colleagues, families, and local stakeholders, they help overcome the challenge of creating awareness about how important for our future it is to preserve nature. 

Biodiversity is complex, and because we operate in different regions, our approach must account for regional differences in species and ecosystems. Our global network of biodiversity ambassadors faces challenges in language diversity, but this has proven to be a strength. Ambassadors from different countries share updates, pictures, and experiences, proving that a shared passion for biodiversity can transcend language barriers.

However, there are challenges, such as limited land availability for tree planting, which is highlighted in areas where trees can contribute to climate adaptation. Identifying the right projects also requires careful research and evaluation to ensure our partners share our commitment to biodiversity conservation.

Looking ahead, we are committed to implementing further measures to support biodiversity at our production sites and expand our community of biodiversity ambassadors. In 2025, we plan to support additional tree-planting projects across Europe to support local biodiversity.
