Concrete, made with cement, is the world's most used material after water - more than 2.5 tons are used per person annually.

But the production of cement and the extraction of aggregates for concrete have significant environmental impacts that we must manage responsibly.

Some of them, such as the emissions of carbon dioxide from cement kilns, have a global impact. Others, such as the effect on biodiversity from quarrying, congestion from transport, and dust emissions, have a local effect.

We must reduce all of our impacts, and we are committed to measure, monitor, and constantly improve our environmental performance.

In this section, we address the environmental impacts of raw-material extraction and cement manufacturing and describe how we are reducing the most significant impacts.
