We have decided to take more incisive actions to progressively reduce CO₂ emissions, optimizing existing technologies and laying the foundations for potential innovations that will lead to the production of “net zero emissions” cement.

Our key actions to reduce CO2 emissions are:

  • Scope 1

    Scope 1 direct emission reduction

    • < 500 kg of CO2 per ton of grey cement (gross)
    • < 800 kg of CO2 per ton of white cement (gross)1

    1 Note: special product with niche applications and markets (0.5% of total world cement production).


    Scope 1 emissions are direct GHG emissions from assets owned or that the company directly controls, such as for example the emissions resulting from limestone calcination, which when heated to high temperatures releases CO2, from the combustion of fossil fuels or from internal transport.

    Our key actions:

    1. Reduction of clinker content down to 68% for grey cement and 80% for white cement by replacing clinker with alternative decarbonated mineral additives such as fly ash and slag and by developing a new cement “low carbon”, FUTURECEM™, which allows to reduce CO2 emissions by over 30%.
    2. Greater use of alternative fuels to cover 77% of energy needs (grey cement). We promote a circular economy by reusing waste and biomass to replace fossil fuels, reducing carbon emissions.
    3. Increased use of alternative raw materials resulting from other production processes (such as fly ash and blast furnace slag) to replace limestone, reducing CO2 emissions.
    4. Optimization of the fuel mix and installation of multi-fuel burners in the kilns through the use of natural gas, a fossil fuel with 20% lower emissions than petcoke.
    5. Carbon capture and storage: new technologies such as carbon capture and storage (CCS) will be necessary for the transition to a “net zero” model. We participate to some CCUS (carbon capture, usage and storage) projects, such as ConsenCus and Greensand.


    To facilitate the Group's transition to a low-carbon economy, any investment decision is based on an internal CO2 price to determine the profitability of each investment and tested under multiple scenario analyses to 2030.

     

    Investments included in the Industrial Plan period (2021-2023)

    1. Kiln modernization of our Belgian plant to increase alternative fuels use from current 40% to 80%
    2. Construction of a new calcination plant in Aalborg for FUTURECEM™ production
    3. Use of natural gas in Aalborg and installation of kiln multi-fuel burners
    4. Digitization of the manufacturing process, maintenance, inventory management and spare parts in the main production plants.

     

    Our 2030 targets

    GREY CEMENT 2020 2022 2025 2030
    Use of traditional fuels in % 72% 64% 57% 23%
    Use of alternative fuels in % 28% 36% 43% 77%
    Clinker ratio 82% 78% 73% 68%
    CO2 emissions (kg CO2/ton cement) 718 679 577 494

     

    WHITE CEMENT 2020 2022 2025 2030
    Use of traditional fuels in % 97% 96% 95% 94%
    Use of alternative fuels in % 3% 4% 5% 6%
    Clinker ratio 82% 82% 82% 80%
    CO2 emissions (kg CO2/ton of cement) 915 915 870 808
  • Scope 2

    Scope 2 direct emission reduction

    • -25% of Scope 1 and Scope 2 emissions by 2030 (vs. 2020)
       

    Scope 2 emissions include indirect emissions from the generation of purchased or acquired electricity, steam, heat or cooling. For example, they are related to the electricity used in the cement grinding mills.

    Our key actions:

    Use of electricity produced from renewable sources: through the direct installation of wind turbines in Denmark with an installed capacity of 8.4 MW, photovoltaic panels in Belgium or by increasing the purchase of electricity from renewable sources from third parties.

     

    Investments included in the Industrial Plan period (2021-2023)

    1. Installation of two wind turbine generators at Aalborg plant

     

  • Scope 3

    Scope 3 indirect emission reduction

    Scope 3 emissions are all indirect emissions (not included in Scope 2) that occur in the value chain and include both upstream and downstream emissions.

    Our key actions and objectives:

    Scope 3 indirect emissions account for 20% of total emissions. In 2020 we started examining our suppliers' CO2 emissions to understand how they could be reduced and how to develop mutually beneficial projects.

    In total, 55 suppliers (30% of total purchases by value) were invited to participate to CDP Supply Chain program. Each supplier was asked to disclose their risks and opportunities associated with climate change, their emissions, details about their emissions management strategy, i.e. targets, and the actions taken to reduce their emissions.

    In this way Cementir Group can:

    • Monitor the Scope 3 emissions of its supply chain
    • Monitor the actions taken by suppliers to manage the risk of climate change
    • Raise climate change awareness among suppliers
    • Identify reduction focus areas in line with “science-based” guidelines.

    To support this commitment and increase supplier response rates, dedicated supplier training webinars were held. This activity was aimed at communicating the importance and benefits of transparent disclosure on emissions and climate impact.

Collaboration with local institutions for the reduction of CO2 emissions

Cementir actively collaborates with local Danish institutions to contain CO2 emissions.

Our key actions:

  1. Energy recovery: in Aalborg we recover excess heat from cement production to provide district heating to local households. The recovered thermal energy is used for heating around 36,000 homes in the city of Aalborg, Denmark. In 2020, the Aalborg plant supplied approximately 1.8 million GJ of energy to the Municipality of Aalborg, saving 150,000 tons of CO₂ annually. The objective is to increase the supply of district heating from current 36,000 to over 50,000 households.
  2. Commitment to public policies related to carbon emissions. Cementir Group actively participates in discussions regarding Danish industrial policy at national and global level, involving, among other issues: climate change, sustainable infrastructures, circular economy, alternative fuels and waste management frameworks. Since November 2019, the Group has been involved in the most ambitious CO2 reduction project sponsored by a national government, the Danish one. Through the CEO of the associate Aalborg Portland, Cementir Group is leading the climate partnership for the Danish energy-intensive industry; the technical working group will provide the Danish government with the forecast of the achievable CO2 reduction potential and define the prerequisites (policies, research, innovation, subsidies, etc.).
