The concrete industry is responsible for 8% of global greenhouse gas emissions, primarily due to the cement in concrete, which accounts for 85% of these emissions. Clinker production in particular has a huge carbon footprint.

There are other hydraulic binders which can replace cement in concrete, however. Amongst these binders, Ecocem GGBS is the best low-carbon solution. In fact, life cycle analysis of Ecocem GGBS in France has shown that its production is responsible for 45 times less CO2 than an equivalent amount of OPC*!

A tonne of Ecocem GGBS releases 16kg of CO2, making it a very low-carbon material. The more Ecocem GGBS you add, the more sustainable your construction will be. We provide assistance to all of our customers in order to optimise their use of Ecocem GGBS.

As a product created using a circular economy, Ecocem GGBS not only avoids tonnes of CO2 emissions in the construction sector, it also avoids the quarry extraction of thousands of tonnes of limestone and clay. This material is already well known in the construction sector and many buildings and infrastructure projects built with concrete using Ecocem GGBS have already received national and international environmental labels and certifications: LEED, BREAM, E + C-, BBCA, BDM, BDO, BDF, HQE and more.

If you would like to start using Ecocem GGBS or perhaps increase and optimise your use, contact our Application team or our Sales team. They will advise you and help you to discover the next generation of materials.
