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. The GCCA said that the deal recognises the need for deep, rapid and sustained reductions in global CO2 emissions.

GCCA chief executive officer Thomas Guillot said “We welcome the progress made at COP28. Decarbonising global industries such as ours will take the collective effort of governments and industry, finance and policymakers, scientists and civil society, all working together. On behalf of our industry and alongside our members who represent the majority of cement production globally, we participated in the preparation and launch of a number of key initiatives that will help enable the shift to net zero – including the Industrial Transition Accelerator, Cement Breakthrough, and Carbon Management Challenge.” He added “We are fully committed to decarbonising our sector and have a detailed net zero commitment and pathway which we are already working towards, including the substitution of fossil fuels, the use of renewable energy and the deployment of new technologies such as CCUS.”

World: Carbon capture technology developer Nuada has entered into partnerships with four global cement market leaders. Cementos Argos, Cementos Molins, Holcim and Siam Cement Group (SCG) will all collaborate with Nuada to evaluate its latest carbon capture system for use in cement plants. The parties concluded the agreements with the support of the Global Cement and Concrete Association (GCCA), through its Innovandi Open Challenge.

Cementos Argos future tech leader Daniel Duque said “The GCCA Innovandi Open Challenge is a tremendous initiative where cement players collaborate with innovative companies that are developing the technologies and business models of a low CO₂ construction industry. Nuada technology is a very interesting proposal with great potential.”

Cementos Molins’ chief innovation officer, Ignacio Machimbarrena, said “We are steadfast in our commitment to achieve carbon neutrality by 2050. Acknowledging the crucial role of carbon capture in this mission, we see Nuada's innovative Metal-Organic Framework (MOF) technology as a promising solution. Cementos Molins is fully dedicated to supporting this pioneering technology and collaborating with industry partners to pave the way for a greener future.”

Holcim’s global head of research and development, Edelio Bermejo, said “With carbon capture projects around the world and a commitment to invest US$2.28bn by 2030, we are leading our industry’s transition to a net-zero future. Partnering with Nuada will facilitate the testing and accelerate the deployment of their technology, ultimately supporting the scaling up of carbon capture efforts. We look forward to continued innovation and collaboration within the industry towards the goal of a net-zero future.”

SCG carbon capture and utilisation (CCU) director Surachai Vangrattanachai said "Collaborating with Nuada has been instrumental in our pursuit of innovative solutions. Their commitment to advancing technology aligns seamlessly with SCG's vision for sustainable progress. Together, we aim to pioneer transformative initiatives that drive us closer to net zero emissions.”

The GCCA’s cement, innovation and ESG director Claude Loréa said “This announcement is a testament to the success of the GCCA’s pioneering Innovandi Open Challenge Programme. It’s great to see Nuada – one of the first start-ups we worked with when we launched the programme in 2021, going from strength to strength, and helping to develop the vital carbon capture technology our industry needs to help us achieve net zero by 2050.”

Nuada co-chief executive director Conor Hamill said “The commitment of these major cement players to collaborate with Nuada attests to the potential of our carbon capture innovation as a cornerstone solution for low-carbon cement, and we eagerly anticipate working together to accelerate its deployment.”

The 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.

World: The Global Cement and Concrete Association (GCCA) has received over 70 submissions to its Innovandi Open Challenge 2023, and is now preparing the shortlist of startups to present their pitches on 30 June 2023. The Innovandi Open Challenge seeks new disruptive technologies to help to achieve net zero cement and concrete production by 2050. Startups selected under the challenge will have the opportunity to partner with the GCCA and its members to further develop their products.

GCCA cement director and innovation lead Claude Loréa said “To receive more than 70 quality applications from start-ups for this year’s Innovandi Open Challenge is hugely encouraging, and shows what level of interest and work is being done to help drive climate action, with applications received from every region of the world." She concluded "Our vital industry needs products which are affordable, scalable and easily adopted. We look forward to sifting through the applications with our member companies and working with those who are selected.”

Colombia: Federación Interamericana del Cemento (FICEM) and the Global Cement and Concrete Association (GCCA) have announced their next steps to accelerate the decarbonisation of cement production in Latin America and the Caribbean. The partners have named Colombia as the region’s first Net Zero Accelerator host country. The initiative works to identify barriers to decarbonisation and to recommend policy changes to make an immediate impact. Along with fellow Net Zero Accelerator host countries Egypt, India and Thailand, Colombia brings the total coverage of the initiative to 10% of global cement capacity.

GCCA chief executive officer Thomas Guillot said “The urgency of addressing climate change becomes clearer every day. Last year, our industry made a breakthrough Net Zero global commitment to reduce our carbon footprint, and we are now driving action in Latin America to make real change in one of the regions predicted to use the most concrete and cement in the coming decades. Our Roadmap Accelerator programme, previewed today by our members and affiliate (FICEM) at Latin America and the Caribbean Climate Week, highlights the tailored policies and tools we will use to ensure that Net Zero concrete and cement is achieved by 2050.”

US: The Global Cement and Concrete Association (GCCA) hosted chief executive officers (CEO)from across the global cement industry at its CEO Gathering in Atlanta, Georgia, on 9 June 2022. The event explored the best ways for the sector to progress towards net zero CO₂ emissions. Speakers included: UN special advisor on climate Selwin Hart, US Department of Energy assistant secretary for fossil energy and carbon management in the Brad Crabtree, architecture firm Gensler CEO Diane Hoskins, Chair of Oil and Gas Climate Initiative (OGCI) executive chair Bjorn Otto and climate economist Gernot Wagner.

GCCA CEO Thomas Guillot said “To achieve net zero and enable the delivery of the sustainable built environment of the future, there needs to be ongoing engagement and deeper collaboration between our industry and government in the years ahead. Targeted government policy will be vital to removing barriers and to expediting our industry’s decarbonisation plans.”

World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).

Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO₂ emissions by 2030 and the elimination of 4.9Bnt of CO₂ emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.

GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”

There was good news from the corporate finance sector for cement producers this week in the form of an approving statement by Fitch Ratings. It declared that it expected the sector to be able to pass on the costs of decarbonisation to customers due to a lack of alternatives. It recognised the challenges posed by regulators, investors and societal pressure but, even so, it suggested that cement was still an industry worth backing. Or at least for now. Added to this, it forecast that demand for building materials would grow to support the transition to a low carbon economy and to combat the damage caused by climate change. It did admit that the capital or operating costs required to decarbonise are seen as being potentially large, especially with uncertainty over how much governments will pay or incentivise. Yet the timescales involved are beyond the ratings agency’s ‘horizon’ hence no really disruptive shifts in producer economics are expected anytime soon.

This was obviously a win for the cement industry and its cheerleading associations led by the Global Cement and Concrete Association (GCCA), the World Cement Association and the regional associations. After all, the increasingly convergent message to the wider world has been along the lines of ‘concrete is part of the solution and you need our products because there’s nothing else.’ Good timing then for the GCCA to launch its collaboration with the World Economic Forum, the ‘Concrete Action for Climate’ (CAC) initiative. The collaborative platform is planned to help drive the industry’s journey to carbon neutral concrete by 2050 as part of the wider Mission Possible Partnership, a wider coalition of public and private organisations working on setting the heavy industry and transport sectors towards net-zero. Expect lots more of these kinds of announcements on the road to the 26th UN Climate Change Conference of the Parties (COP26) taking place in Scotland in late October 2021.

Fitch Ratings did point out that societal awareness was likely to accelerate decarbonisation. The sharp end of this trend was experienced by the building materials industry this week when environmental activist group Extinction Rebellion forced operations to stop temporarily at LafargeHolcim’s Port de Javel ready-mixed concrete plant in Paris on 30 June 2021. This followed a similar incident by the same group at a LafargeHolcim subsidiary ready-mix plant in London in mid-2019. Given the share of global CO₂ emissions from the cement-concrete production chain, it is perhaps surprising that climate activists haven’t targeted clinker-producing cement plants directly in the same way that they have gone after coal-fired power stations. Clinker kilns are, after all, the source of the majority of the sector’s emissions. However, blockading a concrete plant in the city may conjure up a more potent media image than doing the same to a factory out in the country.

Instead the battles with cement plants and their quarries tend to be of a ‘not in my back yard’ (Nimby) nature. Or rather ‘not in my monastery (Nimmon?) this week, with the news that a subsidiary of YTL Cement in Malaysia is attempting to evict a group of Buddhist monks and their underground place of worship from a quarry on Mount Kanthan in Perak. In the latest twist of the long running saga, the monks have hit back with an attempt to get their portion of the site recognised as a place of worship and a heritage site. Thankfully a more positive example of how quarries can fit in with the wider community could be found this week in the guise of an archaeological dig at CRH subsidiary Tarmac’s Knobb’s Farm quarry in Cambridgeshire, UK. The discovery of a Roman Britain-era cemetery with a high proportion of decapitated bodies may have been gruesome but the relations between the operator and the archaeologists were much more harmonious. Another recent example was the discovery of what may be a new precursor species of humans, unearthed at a quarry run by Nesher-Israel Cement Enterprises site at Ramla in late June 2021.

The paradox building materials producers pose to environmental activists could be summed up by the record heat wave that hit the north-western region of North America recently. CO₂ emissions, in minor part produced by the cement and concrete industries, are the most likely reason for an increased frequency of extreme weather events such as this. Yet, infrastructure such as pavements and roads were widely reported as having buckled in the heat, principally because they weren’t built for such high temperatures. They will have to be rebuilt to withstand similar temperatures in the future. Building materials can thus be seen as both part of the problem and part of the solution. Yet with net zero targets nearly 30 years away it seems likely that continued extreme weather events and their potentially lethal consequences will speed up the public demand for decarbonisation. It is worth noting here that one of Extinction Rebellion’s demands in the UK is that the country should become net zero by 2025.

Fitch Ratings has cast its vote for now and Extinction Rebellion and its fellows are set to continue to wage their political campaigns. In the meantime it is debatable how much spiritual solace will be found by the monks of Mount Kanthan during blasting hours at the neighbouring quarry.

UK: The Global Cement and Concrete Association (GCCA) has launched Concrete Action for Climate (CAC) in partnership with the World Economic Forum. The GCCA says that CAC will support industry, civil society, governments and investors to coordinate global climate actions towards 2050 net-zero targets. The initiative represents 40% of the global concrete and cement industry through the GCCA and will bring it together with external expertise and influence. It will achieve its aims by helping to help deliver and coordinate global climate action, stimulating demand for sustainable materials and ensuring appropriate financing and public policy is in place to help the sector reduce its carbon footprint, according to the association.

CAC chair Dominik von Achten said, “Concrete is vital to the development of the modern world, being used to develop key infrastructure like safe homes, bridges and hospitals, as well as supporting the transition to clean energy. Strong action to improve the sustainability of cement and concrete is already underway, but the industry needs to engage and collaborate with others to help drive collective action towards achieving carbon neutral concrete for the world. Today’s launch of the CAC platform is a great example of such collective action. It’s encouraging and exciting to see influential, global organisations from across the world come together to support the cement and concrete industry on its path to carbon neutrality.”
