Carbon Footprint

For years, we have focused on reducing our emissions, increasing energy efficiency in our operations, using lower emission alternatives to traditional fossil fuels, decreasing our clinker factor and promoting renewable energy.

As part of our core strategy, we strive to implement sustainable construction practices and develop products that help society meet green growth goals.

We have significantly increased our use of low-carbon alternative fuels, surpassing our CSI target of 15 percent alternative fuels usage by 2015, and have set a new target to reach 35 percent by 2020.

We also replace traditional energy intensive clinker with slag, fly ash and pozzolans, contributing to a reduction in the CO2 footprint of our cementitious products. In 2015, our overall clinker factor was 78.6 percent, down from 84.3 percent in 1990, and our emissions of CO2 per ton of cementitious products dropped by 21.6 percent compared to 1990, putting us on track to meet our 25 percent reduction target by 2020.

As a result of our initiatives to reduce our clinker factor, increase the use of alternative fuels and reduce our indirect emissions through the consumption of renewable energy, we avoided more than 8 million tons of CO2 emissions. That’s comparable to offsetting the average annual emissions of 1.5 million passenger vehicles.

Expanding CDM & VCS Projects

Through programs such as the United Nations’ Clean Development Mechanism (CDM) and the Verified Carbon Standard (VCS), CEMEX has been working for more than a decade in the identification, documentation and registration of projects that mitigate carbon emissions below typical levels and generate equivalent offsets.


Promoting the Use of our Carbon Footprint Tool

Central to our CO2 reduction efforts is our Carbon Footprint Tool (CFT). It helps us quantify the direct and indirect amount of CO2 emitted during the production of our products on a cradle to- grave basis, including embedded CO2 in raw materials, energy carriers, transports, etc. The CEMEX CFT is being used in all cement, aggregate and ready-mix sites under our operational control and information is readily available to all CEMEX customers interested in the analysis of any product supplied by the company.
