UK: Hanson has signed a memorandum of understanding with Shell to work together to explore opportunities that help the construction industry’s transition to net zero emissions.

Under the agreement the companies plan to explore: using hydrogen for transport and industrial processes; using capture utilisation and storage (CCUS) in cement production; looking at lower carbon fuels and electric vehicles; digital innovations in energy production, consumption and efficiency; improving bitumen and asphalt technology; and renewable energy sources such as solar installations and batteries to replace diesel generators. In addition, the companies say they will consider the possibility of collaborating in future business opportunities or new business models, which will create value and scope for further decarbonisation.

Hanson’s chief executive officer Simon Willis said, “We are already working together on several initiatives to decarbonise asphalt with bitumen materials and innovations which promote long life, increased use of recycled materials, low carbon products and the circular economy.” He added that “Hanson and Shell have a long-established working relationship and are committed to sharing knowledge and resources to jointly work on projects that will facilitate our transition to net zero emissions.”

Mexico: Cemex has expanded its Executive Variable Compensation program, which includes progress on its carbon reduction goals as a variable, to cover over 4500 executives. The initiative is part of the company's Future in Action program, which focuses on reducing the carbon footprint of Cemex's operations and products to become a net-zero CO2 company by 2050. From the start of 2022, the CO₂ emissions component will have an impact that will range from -10% to +10% in the total cash payout of the annual executive variable compensation.

India: Dalmia Cement (Bharat) has signed a memorandum of understanding (MOU) with Denmark-based FLSmidth to collaborate in the research and development of sustainable solutions for cement manufacturing. The agreement has been arranged under the ‘Green Strategic Partnership’ initiatives between Denmark and India that cover energy and climate change.

Under the MOU both companies will cooperate on a range of areas such as substituting conventional energy supplies with renewable sources and working towards CO₂ emissions abatement. Both companies have committed to contributing research and development towards eventually building an industrial scale production plant where the new concepts can be further tested.

Mahendra Singhi, the managing director and chief executive officer of Dalmia Cement (Bharat) said, “In alignment with the ambitious net zero vision of our Prime Minister Narendra Modiji and given the strength and stature of our respective organisations, this association will provide futuristic solutions to the cement and concrete industry to emerge clean and green.” He added that India and Dalmia Cement in particular were keen to develop a roadmap for the implementation of Industry 4.0 with totally decarbonised cement plants and a ‘lighthouse’ cement plant.

India: The Global Cement & Concrete Association (GCCA) India has released a report entitled ‘Blended Cement – Green, Durable & Sustainable’ to promote the advantages of different types of blended cement over Ordinary Portland Cement (OPC). The report was released by Anil Agrawal, Additional Secretary Department for Promotion of Industry, and Internal Trade (DPIIT), Ministry of Commerce & Industry at an online event hosted by the Indian branch of the Global Cement & Concrete Association (GCCA).

“Blended Cement is the top priority and will play a key role in decarbonising the infrastructure segment. I am happy to see that the global cement and concrete industry has taken the lead, and they have come up with a roadmap. Now the Indian cement sector is developing an India specific detailed roadmap for the cement and concrete industry to achieve the net-zero CO₂ concrete by 2050 in a time-bound manner,” said Agrawal.

The report is a collation of the information about blended cement and its advantages. It highlights the performance improvement possible through this replacement, making blended cement an attractive means to achieve sustainable infrastructure development. It also showcases the benefits of different blended types of cement over OPC based on hydration, microstructure and permeability, rheology and workability, strength development, shrinkage (chemical, autogenous, and drying) and cracks, leaching, alkali-aggregate reactivity, sulphate attack, reinforcement corrosion, long-term durability of construction and usage in preparation of high strength concrete.

Australia: Adbri has committed to reduce its cement's CO₂ emissions by 20%/t by 2030. WA Today News has reported that the company also aims to offset 100% of CO₂ emissions from its electricity consumption by 2030. It aims to achieve net zero carbon cement production by 2050. Adbri says that it is Australia's only cement producer not to use coal, relying instead on a combination of gas and refuse derived fuel (RDF).

CEO Nick Miller said "This net-zero emissions roadmap builds on our strong decarbonisation progress to date and establishes clear targets and actions we will advance as we strive to achieve net zero emissions by 2050."

Middle East/North Africa: The World Cement Association (WCA) has called on its members in the Middle East and North African cement sectors to take new actions towards industry decarbonisation. UAE-based consultant and WCA member A3 & Co has said that companies in the region have the potential to cut their carbon footprints by up to 30% with no new capital expenditure required. The Middle East and North Africa accounted for 15% of global cement production in 2021. In the region, only the UAE and Saudi Arabia have committed to national net zero carbon targets, for 2050 and 2060 respectively.

WCA CEO Ian Riley said “There has been a lot of discussion in Europe and North America about decarbonisation roadmaps for the cement industry and good work has been done to start on this journey. However, 90% of the world’s cement is produced and used in developing countries; to impact overall industry emissions we must include these stakeholders. Cement companies in the Middle East have some low hanging fruit to take advantage of, which will lower costs at the same time as reducing CO2 emissions. At WCA we have a number of programmes that can help them realise this opportunity."

France: Sustainable concrete producer Materrup has shared plans for its upcoming Bordeaux precast concrete elements plant. The L’Usine Nouvelle newspaper has reported that the facility will produce precast elements from Materrup’s cement-free concrete, which it produces from uncalcined clay, an activator and a precursor at room temperature. The technology, called Clay Cement 1 (MCC1), reduces CO₂ emissions by 50 – 80% compared to ordinary Portland cement (OPC), according to the producer. It previously opened a Euro7m 50,000t/yr plant in the Atlantisub Business Area in Saint-Geours-de-Maremne, Nouvelle-Aquitaine.

World: The Global Cement and Concrete Association (GCCA) has launched new Net Zero Accelerator initiatives under its 2050 Net Zero Global Industry Roadmap strategy in several countries. The new initiatives will identify barriers to decarbonisation and recommend key actions in Colombia, Egypt, India and Thailand. The association will set out national roadmaps with reduction levers, identify funding possibilities and enter into policy dialogues with national governments. Together, the four countries account for 10% of global cement production.

Chief executive officer Thomas Guillot said "Last year, our industry made a breakthrough net zero global commitment. This is the next logical step as we move our focus from a global roadmap to driving decisive local action." He continued "Global cooperation between governments and industry is crucial to ensuring net zero targets are met. Our Net Zero Accelerators will offer collaboration and support to a number of target countries to help them decarbonise and align with the global roadmap. I'm proud to launch the first phase of the Accelerator programme to assist these nations in embracing greener technologies and work towards a more sustainable future together. I now call on more partners around the world to join us and be part of this movement."

Japan: Taiheiyo Cement has released its interim carbon neutral goals to 2030. The group intends to reduce its CO₂ emission intensity across the entire supply chain by 20% or more compared to 2000. Total domestic CO₂ emissions should be decreased by at least 40% compared to 2000. The company intends to invest US$820m towards these goals. Ultimately the cement producer wants to become carbon neutral by 2050.

US: The California Department of Transportation (CalTrans) has approved the use of Portland limestone cement (PLC) in its projects. The California Nevada Cement Association (CNCA) says that the move has the potential to eliminate 25,500t/yr of CO₂ emissions.

The CNCA plans to achieve cement and concrete carbon neutrality by 2045 through three priority actions. These are investment in promising and critical long-term technologies (crucially carbon capture, utilisation and storage (CCUS) technologies), increased alternative fuel (AF) substitution and the acceptance of PLC for CalTrans projects. Thus, the latest CalTrans decision marks the establishment of one pillar of the CNCA’s ambitious plan for net zero.
