Mexico: Cemex says that it has received validation from the Science-Based Targets Initiative (SBTi) for its 2050 Net Zero Roadmap. The roadmap sets out strategies, including carbon capture, for ‘aggressive CO2 reductions’ across Cemex’s entire value chain, in order to achieve carbon neutral cement production by 2050. The group’s current carbon capture projects portfolio has the potential to reduce its CO2 emissions by 3Mt/yr.
Cemex CEO Fernando González said “The construction industry is essential to the development and wellbeing of society, and its transition to carbon neutrality is achievable. The SBTi’s validation of our decarbonisation target attests to this, as well as the strength of our commitment.”
Mexico: Cemex Mexico plans to install hydrogen injection systems at four cement plants across Mexico. The producer will use the technology to increase alternative fuel (AF) substitution at the plants by 8 - 10%. A 40% reduction in Scope 3 purchased fuel emissions forms part of Cemex's 2020 - 2030 CO2 emissions reduction strategy. Through the decarbonisation and circular economy pillars of its Future in Action plan, the group aims to become carbon neutral by 2050.
Cemex Mexico president Ricardo Naya said "Hydrogen is a key technology to accelerate the implementation of our climate action roadmap."
The El Financiero newspaper has reported that Cemex set a new group record AF substitution rate of 34% in September 2022. It uses hydrogen at all of its European cement plants and at one plant in the Dominican Republic.
Cemex Dominicana partners with Nestlé Dominicana for alternative fuel co-processing
06 December 2022Dominican Republic: Cemex Dominicana has announced the signing of a new sustainability agreement with food producer Nestlé Dominicana. Under the agreement, Cemex Dominicana will co-process Nestlé Dominicana's non-recyclable high-calorific solid industrial waste as alternative fuel (AF) in its cement plant.
Cemex's Dominican Republic, Puerto Rico and Haiti regional director José Antonio Cabrera said "This agreement with Nestlé allows us to continue promoting our Future in Action strategy by operating our cement plant with AF." He concluded "We are committed to becoming a net-zero CO2 company."
Energy for the European cement sector, November 2022
30 November 2022This week’s Virtual Global CemPower Seminar included an assessment on how interventions in European power markets might affect efforts to decarbonise industry. The presentation by Thekla von Bülow of Aurora Energy Research outlined how different countries in the European Union (EU) were implementing the forthcoming electricity price cap on ‘inframarginal’ producers to 180Euro/MWh. Each of these different proposals will entail differing levels of structural change to the wholesale energy market. For example, the Agency for the Cooperation of Energy Regulators (ACER) has recommended establishing a series of frameworks including a stronger focus on Contracts for Difference (CfD) schemes to promote renewable energy sources.
These changes are a consequence of the EU’s response to the Russian invasion of Ukraine. Gas prices surged and then pushed up other energy prices in turn to record levels. As this column covered in September 2022, the price of electricity shot up in the summer of 2022 whilst at the same time Russian gas imports ceased. Cembureau, the European Cement Association, called for urgent action to be taken to support cement production due to large increases in the cost of electricity. For example, in its latest overview of the German cement industry, the German Cement Works Association (VDZ) said that the sector has an electrical consumption of 30TWh/yr. Clearly energy policy is of great interest to the industry.
Since then, in late September 2022, Heidelberg Materials’ chief executive officer Dominik von Achten told Reuters that his company was preparing to shift production at its Germany-based plants to times and days when power prices are lower including at the weekend. However, this was dependent on negotiations with the unions. Von Achten also warned of plant closures being a possibility. Then, in November 2022, it emerged that Zementwerk Lübeck’s grinding plant in northern Germany had reportedly been only operating its grinding plant at night and at the weekend due to high electricity prices. Also in November 2022 European energy news provider Energate Messenger reported that Heidelberg Materials was preparing its cement plants in Germany with emergency backup power to keep critical services running in the case of electricity power cuts. One view from the outside came from equipment supplier FLSmidth’s third quarter results where it noted it had, “...started to see the first cases of budget constraints imposed by customers to counter the increasing energy cost. A high utilisation is still driving service activity in Europe, but some customers have put large capital investments on stand-by and we have experienced a slowdown in decision-making processes.” On the other hand it also pointed out that this trend is driving sales of products that helped reduce energy usage and/or switch to alternative fuels.
On the financial side, Holcim reiterated in its half-year report that, on the country, level the group uses a mixture of fixed price contracts, long-term power purchase agreements, on-site power generation projects and increased consumption of renewable energy at competitive prices to reduce the volatility from its energy bills. Both Cemex and Heidelberg Materials said similar things in their third quarter results conference calls. Cemex said that nearly 70% of its electricity requirements in Europe were fixed in 2022 with nearly 30% fixed for 2023. It went on to reveal that around 20% of its total costs for cement production in Europe derived from its electricity bill. Interestingly, it added that a higher proportion of its electricity costs in Germany were fixed than elsewhere in Europe, due to the use of a waste-to-electricity system owned by a third party that is fed with refuse-derived fuel (RDF), but that it was more exposed to floating fuel rates in Spain. Heidelberg Materials added that it supported energy price caps in both Germany and the EU whether they affected it directly or not.
So far it has been a mild start to winter in Europe. This may be about to change with colder weather forecast for December 2022. This will stress test the EU’s energy saving preparations and in turn it could force the plans of industrial users, such as the cement sector, to change. Some of the cement producers have commented on the financial implications of rising fuel costs but they have been quieter publicly about how they might react if domestic consumers are prioritised. Plant shutdowns throughout cold snaps are the obvious concern but it is unclear how likely this is yet. The variety of energy policies between fellow member states, their own supply situations and the differences between cement plants even in the same country suggest considerable variation in what might happen. If large numbers of cement plants do end shutting throughout any colder periods, then one observation is that it will look similar to winter peak shifting (i.e. closure) of plants in China. The more immediate worry in this scenario though is whether these plants actually reopen again.

US: Cemex USA and RTI International have secured US$3.7m in funding from the US Department of Energy for their Balcones cement plant amine technology carbon capture study. The plant in New Braunfels, Texas, will trial RTI International's non-aqueous solvent (NAS) system, licensed by energy and technology company SLB. Resources News has reported that the system will have a CO2 capture capacity of 670,000t/yr. RTI International's principal project investigator Vijay Gupta said that NAS capture has a 30 - 40% lower energy penalty than preceding solvent-based technologies.
Cemex USA president Jaime Muguiro said "We remain committed to exploring technologies that can help us meet our targets as we build a more sustainable future. We are striving to cut emissions across all our operations, and this study with RTI International is one of the many steps Cemex is taking to achieve our objectives."
93% of Cemex's cement customers now use Cemex Go sales platform
23 November 2022Mexico: Cemex has recorded a total of 50,000 users of its Cemex Go online sales platform since its launch in 2017. Exchanges via the platform account for 93% of the group's global cement customers and 85% of concrete customers. Cemex Go's net promoter score (NPS) customer satisfaction rating rose by 50% between November 2018 and November 2022.
Chief executive officer González Olivieri said "Cemex Go is an important enabler in our transition to a lower carbon industry by improving supply chain logistics, moving to a paperless industry and increasing efficiency throughout the construction sector."
Cemex announces raft of carbon capture projects
22 November 2022Mexico: Cemex has announced a raft of new carbon capture projects in Europe and North America. When commissioned, they will bring its total installed CO2 capture capacity to over 3Mt/yr. The projects consist of three front-end engineering (FEED) studies to scale installations of Australia-based Leilac’s direct separation technology at Cemex cement plants in Germany, Poland and the US; a fourth FEED study for 95% capture installation at the Balcones, Texas, cement plant using RTI International's solvent capture technology and a development partnership for the cement industry's most comprehensive carbon capture, utilisation and storage (CCUS) studies at eight further cement plants in Europe, Mexico and the US.
Chief executive officer Fernando González said “CCUS brings together the essence of our strategic priorities: sustainability and innovation. Our Future in Action programme to achieve sustainable excellence and become a net-zero company is all about measurable, verified progress towards the most ambitious decarbonisation pathway in the industry. Although CCUS technologies are not ready to be scaled quite yet, it will take relentless work and innovation to ensure their viability in time to avoid the most damaging effects of climate change.”
Cemex USA Knoxville cement plant worker dies in coal pile collapse
14 November 2022US: A coal pile collapse at Cemex USA's Knoxville, Tennessee, cement plant killed one worker at the plant earlier in November 2022. Local press has reported that Thomas Mitchell, aged 21, died at the scene.
Cemex says that it is cooperating with an on-going investigation into the disaster.
Cemex resets sustainability targets aim for 1.5ºC scenario
11 November 2022Mexico: Cemex says it has validated its 2030 decarbonisation goals through the Science Based Targets initiative (SBTi) for alignment under their new 1.5°C scenario. Under the new target the group plans to reduce its Scope 1 (direct) emissions by 47% less of CO2 per ton of cementitious material and 35% less of carbon content in concrete compared to a 1990 baseline. A Global Cement estimate suggests that Cemex has set its 2030 target to around 425kg CO2/t of cementitious product compared to 800kg CO2/t in 1990 and 591kg CO2/t in 2021.
The group also intends to reduce its Scope 2 (indirect) emissions via a 65% increase in sustainable electricity consumption. It aims to reduce its Scope 3 emissions through a 25% reduction in CO2 per tonne of purchased clinker and cement, a 30% reduction in transport emissions, a 40% reduction of scope 3 emissions per tonne of purchased fuels and a 42% reduction in absolute scope 3 emissions from the use of traded fuels compared to a 2020 baseline.
Update on COP27
09 November 2022Readers may have noticed the 2022 United Nations Climate Change Conference (COP27) is currently taking place at Sharm El Sheikh in Egypt. Many of the cement companies, suppliers and related associations are present at the annual jamboree and getting stuck in. For example, Holcim’s chief sustainability officer Magali Anderson was scheduled on 8 November 2022 to discuss solutions to decarbonise the built environment at the event’s Building Pavilion, Cemex’s chief executive officer Fernando A González took part in the First Movers Coalition (FMC) panel, FLSmidth is down for a number of talks and both the Global Cement and Concrete Association (GCCA) and World Cement Association are busy too.
Stone cold progress, if any, from the conference is yet to emerge although there is still time given that the event runs until 18 November 2022. No doubt some sort of ‘big message’ style international commitment or plan will emerge from the haggling. However, on the cement sector side, the biggest story so far has been the FMC plan for some of its members to procure at least 10% near-zero cement and concrete for its projects by 2030. Both Holcim and Cemex were founding members of the collation of companies that intend to use their purchasing power to support sustainable technologies in hard to abate sectors. Commitments for the aviation, shipping, steel and trucking sectors were set at COP26 in Glasgow, aluminium and CO2 removal followed in May 2022 and chemicals and concrete were scheduled for November 2022. The latter has started to happen with the formation of the FMC’s cement and concrete group. Companies involved include ETEX, General Motors, Ørsted, RMZ Corporation and Vattenfall. Of these, Sweden-based energy producer Vattenfall has publicly said it is going for the 10% near-zero cement and concrete target by 2030.

Table 1: Net CO2 emission intensity (kgCO2/t) for cement production at selected large cement producers.
While we wait for more announcements to escape from Sharm El Sheikh it might be worth reflecting upon one of the targets some of the cement companies have set themselves for 2030. Table 1 above compares the net CO2 emission intensity for cement production at some of the large cement producers. It doesn’t tell us much, other than that the CO2 emission intensity for these companies was in the region of 550 - 600kgCO2/t of cementitious material in 2021. This compares to 580kgCO2/t in 2020 for the GCCA’s Getting the Numbers Right (GNR) data for the companies it covers. The companies featured in Table 1 are all aiming – or appear to be aiming – for 475 - 525kgCO2/t by 2030. This may not sound like much but it has and will require hard work, innovation, investment and risk on the part of the cement producers. This is also before carbon capture, utilisation and/or storage (CCUS) units will have been built at most cement plants. Yes, until the CO2 emission intensity goes to down to zero, if cement production volumes keep rising sufficiently then total gross CO2 emissions from the cement industry will also increase. Yet, gross CO2 emissions from cement production are likely to peak sometime between now and 2030 if they haven’t already.
One sobering fact to end with is that 1990 is now further in the past than 2050 is in the future. If you can remember George Bush Sr as US president or you saw the film Goodfellas at the cinema then that’s the amount of time we have left to reach net zero. The global economic shocks of the post-coronavirus period and the war in Ukraine are stressing the world’s climate targets more than ever before. Let’s see how COP27 reacts to this. So far though, serious commitments to using low-carbon cement and concrete from big companies are a useful step to entrenching these products in the market.
