Global: The Green Cement Technology Tracker, launched by the Global Cement and Concrete Association (GCCA) and the Leadership Group for Industry Transition (LeadIT), has expanded its scope to include calcined clay production, a significant step in cement industry decarbonisation. This tool, vital for tracking progress towards net zero emissions, initially focused on various decarbonising technologies and has now broadened to cover calcined clay kilns, which have lower energy requirements and CO2 reduction potential.
LeadIT Head Per Andersson said “In order to empower the industry and policymakers committed to emission reductions, our goal is to provide comprehensive tracking of public announcements of investments in low-carbon cement technologies.”
GCCA’s Cement, Innovation and ESG Director Claude Loréa said “Driving down emissions requires investment in new technologies and production methods and incorporating calcined clay can contribute significantly, making it a valuable strategy for sustainable construction.”
The Global Cement and Concrete Association (GCCA) is shining a light on the essential work of women in the cement industry around the world.
To mark International Women’s Day 2024, the GCCA invited women working in its member companies around the world on their perspectives on working in global heavy industry, the importance of gender diversity, and for any career advice they can offer to other women keen to work in the cement and concrete industry. You can hear their thoughts in the videos here.

Global Cement and Concrete Association and China Cement Association to collaborate for cement decarbonisation
01 February 2024World: The Global Cement and Concrete Association (GCCA) has signed a new agreement with the China Cement Association (CCA). The agreement constitutes an historic ‘partnership pledge’ to accelerate cement decarbonisation globally in 2024 – 2026. The partners says that their collaboration will contribute to the development and launch of the upcoming China Cement Carbon Neutrality Roadmap. Equipment supplier Sinoma International Engineering and the European Cement Research Academy (ECRA) will also help to develop the roadmap. The GCCA previously launched its own global net zero roadmap in 2021. Together, GCCA and CCA members account for 90% of global cement production in capacity terms.
GCCA CEO Thomas Guillot, said “The world needs leadership and collaboration like never before, especially on addressing the key issue of our time, climate change. This agreement between the China industry and the global industry is a signal to the world that we stand ready to deliver the essential decarbonised building materials that our planet needs. Cement and concrete enable the key infrastructure, thriving and resilient communities, clean water, safe homes and the shift to clean energy that are essential to a future sustainable world.”
CCA Executive president Kong Xiangzhong said “This important agreement marks a win-win cooperation, and shows where we can collaborate effectively to bring insights, technical know-how and greater focus to our shared decarbonisation mission. I am sure this will create a mutually-beneficial and long-term partnership that will be crucial in building a more sustainable world.”
UAE/UK: The Global Cement and Concrete Association (GCCA) has welcomed the first international agreement to transition away from fossil fuels, signed by 200 countries at the COP28 climate conference in Dubai.

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.
It’s been a good week for graphene usage in the cement and concrete industries, with a trial set to take place at Breedon Group’s Hope cement plant and the inclusion of four graphene projects in the Global Cement & Concrete Association’s (GCCA) shortlist for its second second Innovandi Open Challenge.
The trial at the Hope cement plant was scheduled to take place on 28 June 2023, alongside First Graphene, Morgan Sindall Construction and the University of Manchester. The plan was to use 1.2t of First Graphene’s PureGraph product by testing different dispersion methods and dosage rates. The graphene was going to be prepared as a grinding aid and then added to cement grinding mill feed. Dispersion into the cement production line was planned to occur over a 24-hour period using traditional grinding aid dosage lines, with minimal operational or mechanical change required to the existing plant.
The cement produced was then going to be validated by Breedon’s quality control team to assess its performance enhancement. Overall the trial was going to produce around 2000t of graphene-enhanced cement during the trial. This cement will then be passed to Morgan Sindall Construction for real-world construction demonstrations. First Graphene reckoned that the trial was going to produce the largest volume of graphene-enhanced cement manufactured to date.
First Graphene and the other partners haven’t released any information yet on how the trial went. However, the results will be used to build on data obtained from smaller scale trials previously conducted at a concrete processing laboratory in the UK.
Elsewhere, the 15 projects shortlisted by the GCCA, as part of the Innovandi Open Challenge, were set to pitch their ideas for access to the scheme. The benefits of inclusion on the scheme include access to industry plants, laboratories, networks and the expertise and infrastructure of the manufacturer members of the association. 70 applications were made for the second Innovandi round. The first round in 2021 was focused on carbon capture and utilisation and two projects eventually made it to the pilot stage. This time the emphasis is on low-carbon concrete.
The graphene-related contenders for Innovandi in the current round include Nano Crete, Nanospan India, SeaMix and Versarien Graphene. All four companies are promoting concrete admixtures that use graphene. Given the brief for this Innovandi round, these projects are focused on concrete production as opposed to the trial at the Hope cement plant, mentioned above, which is testing graphene addition during cement grinding.
Nanospan India, for example, is promoting its Spanocrete product. It says that its admixture acts as a superplasticizer and accelerator, allowing for reduced cement and water consumption, a shorter curing cycle and an increase in compressive strength. US-based SeaMix (part of MEP Group), meanwhile, has developed its own concrete admixture that uses chopped basalt fibres and graphene. It too offers greater compressive strength and reduced cement consumption for the resulting concrete. However, it also allows for the use of any non-potable water source, a compelling selling point for construction companies trying to minimise the use of drinking water.
It is early days yet for the application of graphene in the cement and concrete sectors. Graphene was first produced at the University of Manchester in 2004. Just under 20 years later and various products are emerging with test projects slowly gathering pace and even commercial applications, such as SeaMix and others, building up their portfolios. Various challenges such as reduced workability, the high cost of graphene or even concerns about simply handling graphene get raised in discussions about the wider adoption of graphene-based admixtures but so far these do not seem insurmountable. We await the outcomes of the trial at Hope and the selections of the second round of Innovandi.
