The subject of embodied carbon and ways of reducing it is of growing interest in today’s construction industry. Leading the way in its sector, CEMEX UK has introduced a new Carbon Footprint Calculator, a data modelling tool for calculating embodied carbon for the supply of building materials.
CEMEX UK was the first company in its sector to provide the solution of carbon modeling to its customers as far back as 2007. It has now gone one step further with the introduction of its more versatile Carbon Footprint Calculator, mapping out the embodied carbon step-by-step through the supply chain from the manufacture of the raw materials to the delivery of the end product on site, with bespoke reports quickly generated for customers.
To date the Carbon Calculator has been used on approximately 40 projects from single loads to large complex contracts. On one power station contract, it was possible to cut over 25% tonnes of CO2 using the tool.
The tool has data on the embodied CO2 of the raw materials and all CEMEX plants and quarries including gas, water, fuel and electricity. The carbon emissions from transporting the material, whether by road, rail or water, are also an important factor that is included in the calculation.
Having calculated the embodied carbon in a certain type of concrete, the tool can also substitute alternative mixes, for example using CEM II instead of CEMI, Portland Cement and alternative modes of transport, for example, using rail for part of the journey instead of road to reduce the total CO2 emissions.
“The carbon agenda is increasingly in the minds of clients, contractors and legislators. The new Carbon Footprint Calculator can offer our customers a more detailed solution of how to cut carbon but still use a high specification material. Using the tool is an element of our wider solution to advice on and provide high quality materials that are more sustainable over their entire life cycle,” says Andy Spencer, CEMEX UK Sustainability Director.
The Carbon Footprint Calculator works to PAS 2050, a recognized method for assessing the life cycle greenhouse gas (GHG) emissions of goods and services.

- In 2010 CEMEX UK was the first cement company in the world to provide certified carbon labels for its cement highlighting the company’s commitment to reducing the footprint of its cement. The carbon footprint is the amount of carbon dioxide and other greenhouse gases (CO2e) generated by the cement from cradle to grave, including the extraction of the raw materials, to manufacturing, distribution, use by customers and disposal at the end of life.
- CEMEX is a global building solutions company and leading supplier of cement, ready-mixed concrete and aggregates. In the UK, CEMEX also produces asphalt, and has a significant share of the concrete-block paving, and concrete block sectors. Additionally, the company is the leading supplier of concrete sleepers to the rail industry and a supplier of PFA cement additives. CEMEX has a national supply network in the UK with over 360 locations, to ensure that quality building materials are available to customers locally.
