Finland: Finnsementti is carrying out upgrades to its two integrated cement plants as part of its sustainability targets to 2030. The subsidiary of Ireland-based CRH is installing new main burner equipment at its Lappeenranta plant with completion scheduled for mid-2023. The project is intended to allow the plant to increase its use of alternative fuels. The company’s Parainen plant is replacing its satellite coolers with a grate cooler with completion scheduled for the spring of 2024. This work is expected to decrease the plant’s emissions by 10%. Overall the group is preparing to decrease its CO₂ emissions by 30% by 2030 compared to 2021 levels.

Sweden: Heidelberg Materials Sweden has called for swifter action to be taken by the government on a planned upgrade to the mains electricity supply to the island of Gotland. The building materials company is planning to build a full-scale carbon capture and sequestration (CCS) unit at its integrated Slite cement plant on the island by 2030. However, the newly approved plans to build two new electrical transmission cables to Gotland are currently scheduled for completion in 2031. The cement plant is expected to require annual electricity requirements of up to 1.5TWh with a power requirement of up to 250MW when the CCS unit is completed.

The cement producer has welcomed the government’s upgrade plans so far but has impressed the urgency of its timeline to build a CCS unit at the Slite plant. It says it is currently considering investing around Euro850m on the project. If completed the CCS unit is expected to capture up to 1.8Mt/yr of CO₂. The company said that this corresponds to approximately 3% of Sweden's emissions annually.

Iceland: Sementsverksmidjan says it has offset its domestic transport CO₂ emissions through an offset scheme with the government environmental agency Landgræðirin. In 2022 the subsidiary of Germany-based Heidelberg Materials offset 484t of CO₂-equivalent by restoring a birch forest and dry-land ecosystems.

Europe: 12 decarbonisation-focused companies from across the European cement and concrete sector have launched the Alliance for Low-Carbon Cement & Concrete (ALCCC). The alliance has called on policymakers to change building standards to help low-carbon alternatives to enter the cement and concrete markets. It further said that green procurement and targeted financing instruments would help to reduce sectoral CO₂ emissions. It said that a progressive decline in clinker factor to 60%, 50% or 40% by 2050 will reduce CO₂ emissions by over 50%. The ALCCC says that it is ready to lead the sector towards a swift, low-cost and viable decarbonisation pathway. Participants in the alliance include France-based Hoffmann Green Cement Technologies, Ireland-based Ecocem and US-based Fortera.

Fortera's Europe director Thierry Legrand said "Climate action is a global priority, and collaboration is essential to advancing emissions-reducing technologies and policies. This alliance represents collective action by scientists, engineers, entrepreneurs and environmental advocates to reduce CO₂ emissions from cement production."

Germany: Holcim Deutschland has commenced a carbon capture trial at its 950,000t/yr Beckum cement plant in Beckum-Kollenbach, North Rhine-Westphalia. The trial will employ amine scrubbing technology to separate CO₂, which it will then seek to commercialise for other industrial uses. Holcim Deutschland's partners for the project are Technische Universität Berlin and construction engineering firm thyssenkrupp Uhde. The trial also has funding from the German government.

Italy: Italcementi, part of Heidelberg Materials, has filed a patent application for a titanium dioxide-based cementitious material. The Patent Office Journal has reported that the material consists of titanium dioxide (TiO2) imbued with carbon dopants. This is produced by irradiating the TiO₂ in the presence of an inert gas and an organic compound.

UAE: Holcim subsidiary Lafarge Emirates Cement (LEC) has begun construction of a 10MW waste heat recovery (WHR) plant at its 3.2Mt/yr Fujairah cement plant. Supplier Engie Solutions says that it expects to commission the installation later in 2023. Trade Arabia News has reported that the equipment is based on a closed-loop organic Rankine cycle and will eliminate 29,000t/yr of CO₂ - 28% of the Fujairah cement plant's energy-related CO₂ emissions.

LEC general manager Olivier Milhaud said "Engie’s energy-as-a-service model means guaranteed energy savings and higher reliability and resilience, with no capital outlay and no need for additional staff." He continued "We are fully committed to the UAE’s sustainability goals, including the 2050 Net Zero vision."

France: The French cement association France Ciment has announced a new CO₂ emissions reduction target of 50% across the cement industry between 2021 and 2030. The new target for 2050 will be 'virtual carbon neutrality.' The Les Echos newspaper has reported that the commitments replace previous reduction targets of 24% by 2030 and 80% by 2050. France Ciment says that its members are planning estimated investments of Euro5bn towards achieving the goals before 2040. These investments will cover areas including the deployment of carbon capture. Existing public and private investments in the industry's on-going projects to reduce CO₂ emissions amount to Euro1.7bn - sufficient to eliminate 27% of emissions compared with the 2021 baseline.

France Ciment’s President Benoit Pillon noted the necessity of cement in construction, and called for 'decarbonisation as a whole: less clinker in cement, less cement in concrete and less concrete in construction.' He urged the implementation of policies to secure 'decarbonised and competitive electricity.'

Germany: Chemicals company BASF has won a contract to supply its OASE Blue CO₂ separation technology for use in the upcoming 70,000t/yr carbon capture installation at Heidelberg Material's Lengfurt cement plant in Bavaria. The Capture to Use (Cap2U) project, in partnership with fellow chemicals company Linde, aims to capture CO₂ from the plant for use in the chemicals, food and beverages industries.

BASF head of gas treatment Andreas Northemann said “Our portfolio of OASE technologies makes a significant contribution to sustainability and is perfectly suited to help our customers achieve their sustainability targets. This carbon capture and use unit facility has the potential to become a show-case project in a hard-to-abate sector."

Canada: A study led by Douglas Geoffrey in Calgary, Alberta, has patented a method of producing cement from calcium carbonate precipitated in the carbonation of brine. The method mixes the mineral with magnesium oxide and cures it to form cement.

Geoffrey noted that the brine may derive from multiple industrial processes, including fossil fuel and potash production, geothermal power generation and desalination.
