Implementing sustainable practices throughout our manufacturing process is only the beginning of Firth's contribution to sustainable building. Our sustainability pillars focus on carbon reduction, water conservation, the circular economy, supply chain efficiency and social sustainability.

We can design mixes to meet customers’ desired Embodied Carbon (EC) rating, thus making a contribution to the low carbon efforts in the construction industry.

With our new EC³ calculator we are able to
evaluate the 
specific carbon footprint of any
concrete mix 
anywhere in the country.
