Update on cement at COP28
06 December 2023The Global Cement & Concrete Association (GCCA) has been cheerleading at the 2023 United Nations Climate Change Conference (COP28) in Dubai this week with the release of a progress report on the sector’s work towards reaching net zero by 2050. The headline figures are that net CO2 emissions per tonne of cementitious material fell by 23% in 2021 compared to 1990 based on Getting the Numbers Right (GNR) data. Energy efficiency improved by 19% and the fossil fuel component used by the cement sector has fallen to 80% from 98% in 1990. The GCCA has described 2020 - 2030 as the “decade to make it happen” and has set some targets to back this up. Its members intend to reduce CO2 emissions per tonne of cement by 20% by 2030 compared to 2020 levels and concrete CO2 emissions per m3 by 25% over the same time-frame.
The new developments for the cement sector at COP28 so far have been the launch of separate but apparently similar initiatives to help decarbonisation through coordination between nations. The Cement Breakthrough Agenda, backed by the government of Canada and other partners, follows the creation of the Breakthrough Agenda at the 2021 United Nations Climate Change Conference (COP26) whereby designated governments lead so-called ‘Priority Actions’ to decarbonise various sectors. The idea is to collaborate on measures such as policies, regulations and technologies to help reduce the cost of future investment in decarbonisation. The priority actions will be developed in 2023, worked towards in 2024 and then revised on a regular basis thereafter. The German Chancellor Olaf Scholz also launched the so-called ‘Climate Club’ on 1 December 2023 to help developing nations invest in technologies to decarbonise sectors such as cement and steel production. The intention is to set up the technical groundwork for a standardised calculation of CO2 intensity in selected products, such as cement and steel, set definitions on what net zero is for these sectors and then set up a platform to connect countries with funding and technical support from governments and the private sector. Neither the Cement Breakthrough Agenda nor the Climate Club has mentioned funding though.
Additionally, Holcim announced that it had become a founding member of the Sustainable Markets Initiative’s SMI Circularity Task Force. The group aims to promote the circular economy to the private and public sector. Holcim was keen to point out that it is already recycling nearly 7Mt/yr of construction and demolition waste, with a target of 10Mt/yr pencilled in by 2025.
Other groups are not as upbeat as the GCCA though. The Global Carbon Project, for example, has estimated in its annual Global Carbon Budget that global fossil CO2 emissions are set to rise by 1.4% year-on-year to 36.8Bnt in 2023. This figure includes both the CO2 released by cement production and the CO2 uptake from cement carbonation. Ongoing research by Robbie Andrew, a greenhouse gas emissions scientist at the CICERO Center for Climate Research in Norway and the Global Carbon Project, found that process emissions by the cement sector fell for the first time since 2015 in 2022, to reach 1.61Bnt. This decrease was most likely due to China’s falling cement production in 2022, stemming from a downturn in the local real estate sector. However, both the data from GCCA and the Global Carbon Project may be right simultaneously as they look at the emissions of the cement sector in different ways.
The GCCA’s job is to advocate for the cement and concrete sector and it is presenting itself well at COP28. Since its formation, it has set up roadmaps, encouraged collaboration and innovation, and is now reporting back on its progress. Net zero remains the goal by 2050, but the GCCA is being upfront about the role carbon capture, utilisation and storage (CCUS) is expected to play after 2030 and the lack of any full-scale CCUS units so far. Yet it is tracking what has happened so far through the Green Cement Technology Tracker in conjunction with Leadership Group for Industry Transition (LeadIT).
As for the rest of COP28, various reports have been aired in the international press about whether the conference will call for a formal phase out of fossil fuels in some form or another. Whether it actually happens is another matter entirely, especially considering that the president of COP28 is the chief executive officer of the Abu Dhabi National Oil Company, and any eventual language would likely be vague. Yet the work by the GGCA and others has started to make the unthinkable a little more thinkable.
Kenya: Frontier Energy subsidiary Momnai Energy has begun building two solar power plants at sites belonging to Bamburi Cement. One 14.5MW plant will be situated at the producer’s 1.1Mt/yr Mombasa cement plant, while another 5MW plant will be situated at its Nairobi grinding plant. When commissioned, they will cover 30% of the producer’s energy consumption. Momnai Energy will finance, manage and maintain the solar power plants on the basis of a power purchase agreement (PPA) signed between the parties in 2021.
Bamburi Cement chief executive officer Mohit Kapoor said that the project ‘represents one of Kenya's most substantial commercial solar endeavours undertaken by a cement company, and a first for Holcim in Sub-Saharan Africa.’ He added that it will lead to cost savings, reduced vulnerability to load shedding and ‘substantial’ progress towards achieving net zero CO2 emissions.

Cemex launches 1000th reduced-CO2 truck
05 December 2023Mexico: Cemex has reached 1000 reduced-CO2 trucks in operation across its global cement business. This includes trucks fuelled by renewable diesel and natural gas. These efforts have reduced its global transport CO2 emissions by 5% since 2020, in line with the group’s commitment to a 30% reduction by 2030.
Chief executive officer Fernando González said “Our net-zero transition is supported by proven and readily-available lower-carbon technologies that guarantee that we meet our short and medium-term decarbonisation commitments. At the same time, we remain at the forefront of innovation and emerging transportation technologies so we can achieve our ultimate goal of becoming a net-zero CO2 company by 2050.”
Fujairah Cement Industries appoints ThyssenKrupp Decarbon Technologies to upgrade Dibba cement plant
04 December 2023UAE: Germany-based ThyssenKrupp Decarbon Technologies says that it has won a new contract with Fujairah Cement Industries. Under the contract, the supplier will carry out an upgrade at the Dibba cement plant to reduce its CO2 emissions.
UAE: Emirates Steel Arkan (ESA) has appointed consultancy A³&Co. to help plan and implement decarbonisation initiatives at its 5.7Mt/yr Al Ain cement plant in Abu Dhabi. The collaboration will focus on reducing CO2 emissions and costs, in line with the Science-Based Targets Initiative (SBTi)’s 1.5° Pathway for Net Zero and in conformity to the EU’s Carbon Border Adjustment Mechanism (CBAM).
ESA is committed to reducing its CO2 emissions by 40% between 2018 and 2030, and to achieving carbon neutrality by 2050.
Paebbl trials 100t/yr carbon-storing cement reactor
30 November 2023Finland/Netherlands/Sweden: Paebbl has commenced production of its carbon-storing cement using its new 100t/yr Obelix reactor. The company says that the trial represents a 100x scale up of its capacity in under six months. The Obelix reactor produces cement in 500l batches. Paebbl’s cement has a CO2 storage capacity of 200kg/t. It expects to begin shipping samples to early adopter customers in the Benelux and Nordic regions from early 2024. The next scale-up for the company will come with the construction of a continuously operating pilot plant in late 2024, further increasing its cement capacity by a factor of 10.
Taiwan Cement heads west
29 November 2023Taiwan Cement Corporation (TCC) has struck a deal to take control of the Türkiye and Portugal-based parts of OYAK’s cement business. The arrangement will see TCC grow its share of the joint-venture business in Türkiye to 60% from 40% at present and it will fully take over the Cimpor joint-venture in Portugal by purchasing OYAK’s 60% stake. Overall TCC is expected to pay around Euro740m for its acquisitions. A final agreement on the deal is expected to be signed in early December 2023.
The proposed deal follows on from when TCC originally spent US$1.1bn towards setting up joint-ventures as a junior partner with OYAK back in 2018. The situation now appears to have reversed with TCC becoming the main owner of the cement business in Türkiye and the sole owner of Cimpor in Portugal. In Türkiye this gives TCC control over the largest cement producer with seven integrated plants, three grinding plants, 47 ready-mixed concrete (RMX) plants, three aggregate quarries and one paper packaging plant. In Portugal (and Cape Verde) this puts TCC in charge of three integrated plants, two inactive grinding plants, 42 RMX plants, 15 quarries, two mortar plants and a cement bag unit.
This contrasts with last week’s news that CRH is buying one cement plant in Texas (with associated assets) for US$2.1bn. TCC is taking control of 10 plants in Türkiye and Portugal for Euro740m. It is not a fair comparison given the woes of the Turkish economy in recent years, prior joint-venture business ownership and so on. Yet it is one more example of the changing nature of cement company ownership around the world since the mid-2010s.
The state of the economy in Türkiye may well be a factor for the change in ownership at OYAK and Cimpor as well as negative exchange rate trends. High inflation has caused problems in recent years, although the government changed its stance on avoiding putting up interest rates following the elections in May 2023. Yet, in a statement about the OYAK deal, chair Nelson Chang said that “companies that do not understand carbon will not survive in the future.” His company is about to spend Euro740m and become the fifth largest cement producer in the world on the assertion that it does understand carbon. Good luck!
Accordingly, the language in the press releases both OYAK and TCC have released is all about sustainable growth and reducing carbon emissions. However, the detail on how exactly they intend to do this is vague. What is clearer though is that OYAK is hoping that TCC invests in energy storage and related industries such as lithium-ion battery additive carbon black in Türkiye. To this end a TCC subsidiary and OYAK are collaborating on a carbon black plant in Iskenderun and further investments may be in the pipeline. TCC and OYAK are also responsible for a couple of calcined clay projects in Sub-Saharan Africa.
Readers may recall that the chair of Chang pronounced in June 2023 that TCC was aiming to diversify the business towards over 50% sales from non-cement sectors by 2025. However, the share from the cement business was around 68% in 2022 and this latest deal with OYAK will likely send it in the ‘wrong’ direction. The company already has a production capacity of around 77Mt/yr from its cement plants in China and Taiwan. Majority ownership of OYAK Çimento and Cimpor Portugal will bump this up to 99Mt/yr and put the company into the top five of the world’s largest cement producers by capacity.
The final question here is what kind of owner TCC intends to be to its growing cement businesses in West Asia and Europe. Publicly at least, it has come across as a backseat investor since 2018 although it has been a minority owner. This has now changed but it will be interesting to observe whether the subsidiaries in the west will be run at arm’s length or more closely and if TCC unifies its global branding and so on. Watch this space.
Australia/UAE: Industrial CO2 emissions reduction research body Heavy Industry Low-carbon Transition Cooperative Research Centre (HILT CRC) has received an invitation to attend COP28. HILT CRC said that the invitation reflects the importance of collaborative research for the decarbonisation of Australia’s heavy industries, including cement.
Chief executive officer Jenny Selway said “Decarbonising heavy industries is a core aspect of cutting down on global emissions to limit global warming to well below 2°C. The low-carbon technology transition in heavy industry is vital for our future: it will ensure we build sustainable industries and create new opportunities for Australia’s economy.”
