Ecosystems and biodiversity

The UN recently declared 2021-2030 as the 'Decade of Ecosystem Restoration', as the world aims to prevent, halt and reverse the degradation of global ecosystems. We are proud to showcase our biodiversity ambition for 2030 and some environmental achievements from across our global operations.

2030 biodiversity target

As part of our 2030 sustainability ambitions, we have set a target for 100% of our biodiversity-sensitive locations to have a management plan in place, in line with best international practice. Biodiversity is a key consideration for our extractive operations and for site restoration planning. We aim to minimise potential impacts and to restore and rehabilitate disturbed ecosystems, while also creating and enhancing new habitats for rare species.

Reducing the impact of construction projects on biodiversity

Opterra, A CRH Company in Germany, supplied concrete for the Southern Bavaria Bundesstraße motorway project’s green bridge structure. Completed in 2019, the green bridge enables wild animals to cross the busy motorway. By providing a safe crossing point for birds, mammals and insects, green bridges such as this one help to connect habitats, maintaining healthy ecosystems and reducing the ecological impact of new roads.


Further strengthening our environmental performance.


As a leader in our industry, we are committed to better understanding of environmental management and protection, both locally and globally.

Contributing to the circular economy

In 2020, Ecorec, part of our Europe Materials Division, opened a new, solid recovered fuel (SRF) production line at its Pezinok plant in Slovakia. The SRF production line processes industrial and municipal waste, converting it to an alternative fuel that can be used in cement production, increasing Ecorec’s alternative fuel production capacity by 50%.

Preserving in air quality

Finnsementti, part of our Europe Materials Division in Finland, recently received the 'Environmental Act of the Year' award from the city of Parainen for the environmental investments that have taken place at its Parainen plant. In 2020, Finnsementti installed a new baghouse filter at the Parainen plant which has significantly reduced the amount of dust emitted.
