Our Cement Business

Cement and aggregates are critical components of building materials, such as concrete, and in the construction and
maintenance of roads, buildings, bridges and other infrastructure assets that are vital to economic growth and quality of life.
While it is well known that the cement sector is a significant contributor to global GHG emissions, a holistic approach that
takes into account the environmental impacts of embodied carbon during the entire life cycle of cement and concrete
building materials (including materials sourcing, distribution, use, productive reuse, recycling and disposal) means that
cement and concrete products can play an important role in a sustainable low-carbon economy.
