Gabon: President Brice Oligui Nguema of Gabon invited Aliko Dangote, President and CEO of Dangote Industries, to invest in Gabon's cement sector during a visit to the country. Discussions centred on potential cement plant investments to bolster Gabon's infrastructure development. President Nguema noted that the collaboration with Dangote Industries would bring significant benefits, including job creation, technology transfer and enhanced industrial capacity. This potential investment aims to strengthen economic ties between Nigeria and Gabon and enhance Gabon's industrial capacity, with further discussions planned in the coming months to finalise the investment strategy.
Dangote said "We are excited about the opportunity to invest in Gabon. Our goal is to contribute to the country’s economic diversification and industrialisation efforts. By leveraging our expertise in cement production, we aim to support Gabon’s infrastructure sector."
Ban ‘green’ cement!
05 June 2024The Indonesian government emphasised its intention this week to use ‘green’ cement in the construction of its new capital city Nusantara in Borneo. However, this begs the question: what exactly is ‘green’ cement?
In this case, Mohammad Zainal Fatah, the secretary general of the Ministry of Public Works and Public Housing, told state media that his department was “seeking to encourage the supply of domestic-industry-based material resources and construction equipment, which can support sustainable infrastructure development principles." The ministry is working with state-owned cement producers such as Semen Indonesia (SIG) to ensure the provision of sustainable cement and related products. SIG was selected as a supplier for the project in late 2022 and, as of February 2024, has reportedly provided 400,000t of cement from its plants at Balikpapan and Samarinda.
This is admirable stuff. However, the timing of the announcement is curious given that both the head and deputy head of the Nusantara Capital City Authority resigned this week forcing the government to reassure investors that the project was still on. Cue some swift discussion about ‘green’ cement! Previously it was hoped that the first phase of the US$34bn project could be inaugurated on the country’s independence day in August 2024 with civil servants scheduled to start relocating to the site in the autumn.
SIG sells a number of ‘green’ blended cement products and some of these have received Green Label Cement certification from the Green Product Council Indonesia. The group says that these products have contributed up to a 38% drop in CO2 emissions compared to Ordinary Portland Cement (OPC). This compares to the group’s clinker factor reduction rate of 69% and its Scope 1 emissions intensity reduction of 17% to 585kg/CO2/t of cement in 2023 compared to 2010 levels.
Along similar lines, the Alliance for Low-Carbon Cement & Concrete (ALCCC) in Belgium also announced this week that it had released a new policy roadmap aimed at achieving net zero emissions by 2040. Amongst its recommendations were a focus on the standards for cement and concrete to promote low-carbon products and encouragement to create lead markets to develop demand for them.
Crucially, the ALCCC uses low-carbon cement in place of ‘green’ cement and this makes its definition clearer. ‘Green’ cement is a marketing term intended to associate cement with environmentalism. Yet there is no accepted definition describing how these products are more sustainable than, say, OPC. For example, a so-called ‘green’ cement could use 100% clinker manufactured with no CO2 emissions-abatement, but it might be sustainable in other ways such as saving water. For the purposes of this article we’ll assume that ‘green’ cement means a low-carbon one. To further add to the confusion, ‘green’ concrete can be made using OPC in various ways but that’s beyond the scope of this piece. Clearly the world could do with some universal definitions.
US-based research and consulting company Global Efficiency Intelligence came to the same conclusion when it published its ‘What are Green Cement and Concrete?’ report in December 2023. It decided that - despite there being plenty of standards, protocols, and initiatives - there is no general agreement on the definition of ‘green’ cement or concrete. Its emissions intensity for cement summary table can be viewed below. It demonstrates the massive range of emissions intensity between the various standards. It is worth noting here that the description the Indonesian government may have been using for ‘green’ cement could already meet SIG’s Scope 1 emissions intensity reduction for its cement in 2023 depending on the standard being used.
Standard / Initiative / Policy Name | Emissions intensity target (t/CO2 per tonne cement) |
Climate Bonds Initiative | 0.437 & 0.58 |
IEA and IDDI | 0.04 – 0.125 |
First Movers Coalition | 0.184 |
U.S. General Services Administration IRA Requirement | 0.751 |
New York (USA) Buy Clean | 0.411 |

Part of the problem here is that there is a language gap between the simple definition of a cement that is less CO2 emissions-intensive than OPC and the technical definitions used in the specifications and standards. Simply describing a cement product as ‘green’ can potentially cover anything that is slightly better than OPC down to a bona-fide net-zero product. Added to this is pressure from the manufacturers of new and existing cement products that use less or no OPC for regulators to move to performance-based standards to replace existing prescriptive standards, because it makes it easier for their products to be used. For more on this issue see Global Cement Weekly #606. Cement associations such as Cembureau and the Global Cement and Concrete Association (GCCA) have also called in their respective net zero roadmaps for changes to the standards system to promote low-carbon cement and concrete products.
The answer to what is ‘green’ cement is whatever the promoters want it to be. So, it might be helpful if the use of the word ‘green’ were banned in connection to any marketing activity related to cement products. Everyone could then adopt some kind of universal grading system using simpler language. One approach might be to copy the colour-coding scheme used by hydrogen to describe how it is made. One could use yellow for limestone blends, silver for slag, orange for clay, black for OPC made with carbon capture and so on… but not green! Another route might be to mandate the use of the carbon labels that some cement producers have used for at least a decade. Or something like the alphabet energy rating system used in the UK and EU for electrical appliances could be used. It’s too much to hope for a global system but simpler systems in the main markets would make it much easier to determine what exactly is ‘green’ cement.
Indonesia: The Indonesian Cement Association (ASI) has forecast the volume of cement to be used in the construction of the upcoming new capital city, Nusantara, as 1Mt/yr. This corresponds to 1.5% of the current domestic demand of 65.6Mt/yr. The Jakarta Post newspaper has reported that ASI members plan to supply reduced-CO2 cement for the Nusantara project, to help it realise its aims as a ‘green city.’
In 2022 – 2024, the construction of Nusantara is expected to use 1.94Mt of cement. Research from the Bandung Institute of Technology previously forecast in 2022 that the Nusantara project would raise Indonesia’s cement demand by 33% to 84Mt/yr for 20 years from the start of its construction.
Russia sees sustained growth in cement consumption
16 April 2024Russia: Cement consumption in Russia has increased for 13 consecutive months, according to Darya Martynkina, executive director of the Soyuzcement union of cement producers. This figure increased by 8% year-on-year in the first quarter of 2024 compared to the first quarter of 2023, from 10.4Mt of cement to 11.2Mt.
Martynkina said "Development of infrastructure in Russia still does not correspond to long-term economic tasks and society needs. For example, the level of road network coverage in our country and the level of transport mobility are insufficient; high-speed motorways are close to none."
She highlighted extensive projects that will require ‘significant’ amounts of cement, including the North Siberian railway, the upgrade of 75 airports by 2030, improvements to seaports and expansions of the Eastern Range railway and the M-12 highway extending to Vladivostok.
US: The Department of Transportation has announced a US$5m initiative to investigate the use of steel slag in cement and concrete. This will take the form of a collaboration between the Department of Transportation and a selected US-based steel producer and university partner. The initiative seeks to reduce CO2 emissions in the production of building materials. Prospective participants may view the grant opportunity here.
Transport secretary Pete Buttigieg said "We're proud to make this funding available to help develop the next generation of construction materials so that the future of our transport infrastructure is more resilient, more sustainable and made in America.”
Robert Hampshire, deputy assistant secretary for research and technology and chief science officer, said “This funding initiative will develop and advance innovative materials and technologies that support the nation’s goals to decarbonise the transportation sector by 2050, strengthen resilience of the nation’s transportation infrastructure, and address adverse environmental impacts created by the transportation system.”
Portland Cement Association expects US economy to weaken in first half of 2024 before recovery
26 January 2024US: Portland Cement Association (PCA) chief economist and senior vice president of market intelligence Ed Sullivan forecast a recovery of the US economy in the second half of 2024 at the World of Concrete conference in Las Vegas, Nevada. However, Sullivan told attendees that the economy will ‘gradually weaken’ in the first half of the year. The anticipated weakening is compounded by the end of Covid-19 relief programmes, delayed monetary policy effects and credit tightening. Supporting growth throughout the year are some of the US$550bn infrastructure investments under the Infrastructure Investment and Jobs Act. The US government says that 40,000 new projects under the act are either in progress or completed.
Ed Sullivan said "In terms of the construction outlook, there will be a battle between interest sensitive construction sectors and less interest sensitive construction activity such as infrastructure spending and the construction of large manufacturing plants associated with the CHIPS and Science Act."
India: Dalmia Bharat's consolidated sales were US$433m in the third quarter of the 2024 financial year (1 October – 31 December 2023), up by 7.3% year-on-year. This was in part due to an 8.1% rise in the company’s cement sales volumes, amid a nationwide infrastructure spending drive. Its net profit rose by 22% year-on-year to US$32m. The producer partly attributed this to a market correction in the price of raw materials. Premium products accounted for 21% of Dalmia Bharat’s cement sales during the quarter.
Managing director and CEO Puneet Dalmia said “While we believe that margins may improve further from here on, our focus for the next 12 – 15 months will remain on improving our capacity utilisation and delivering industry-leading volume growth.”
Update on Kyrgyzstan, January 2024
03 January 2024Kyrgyzstan had a couple of prominent stories in the press towards the end of December 2023 with news of a new plant and continuing data showing that cement production has grown.
The Chüy project was first announced by the government in mid-2022 when it signed an investment agreement with a consortium comprising representatives from Terek-Tash and ZENIT. More information on the unit emerged this week when the Russian-Kyrgyz Development Fund revealed that it made a loan of US$45m towards the scheme based in the northern Chüy region of the country. The plan is to build a 1.7Mt/yr plant with a budget of US$160m. Equipment to build the plant is reportedly being sourced from companies in China and Russia. Special features of the project include a waste heat recovery unit and the use of ash from the Bishkek Thermal Power Plant in the production process. The plant is expected to be launched in 2024.

One reason why the government might be keen to build a new plant is because cement production has mostly grown in each of the past five years, with the exception of 2020, when the Covid-19 pandemic began. In 2022 it increased by 7% year-on-year to 2.7Mt and the latest data from the National Statistical Committee indicates that it rose by 11% year-on-year to 2.6Mt in the 11 months to the end of November 2023. If this rate held in December 2023 then it looks likely that the country will have produced just under 3Mt in 2023. At the same time the country’s exports of cement have also been falling. In November 2023 the government of Kazakhstan’s Jambyl Region said that it had found investors to support construction of a railway line between the locale and Kyrgyzstan due to a ‘building boom’ in the latter country.
Earlier in 2023 the Eurasian Development Bank (EDB) said it had earmarked US$48m for the modernisation of equipment at the Kant Cement plant, operated by Kazakhstan-based United Cement Group (UCG), also in Chüy region. The plant is the biggest in Kyrgyzstan, running five wet process production lines, according to the Global Cement Directory 2023. The EDB linked its investment to a hydroelectric project in the country that it is also funding, pointing out that such structures require lots of cement and concrete. This follows a previous upgrade project by owner Kazakhstan-based United Cement Group (UCG) at the plant from 2021 to March 2023. This involved efficiency and environmental gains such as installing bag filters and converting a cement grinding mill to a closed circuit. China-based and CNBM subsidiary China Triumph International Engineering was the lead project partner. In early December 2023 UCG announced that it had signed another contract with China Triumph International Engineering over the summer to build a new dry production line at the site with a clinker capacity of 0.8Mt/yr. At the time of the announcement it said that preparation of the construction site had started and that work had begun on installing a pile foundation.
Finally, one more Kyrgyz news story of note in recent months was the announcement in October 2023 that the government had effectively nationalised the Kurmentinsky Cement plant in Issyk-Kul Region. The reason why it had done so was unusual because it said that a 93% share in the company running the plant had been transferred to the State Property Management Agency following the death of its former owner. The former owner was one Kamchybek Kolbaev, an organised crime boss who had been listed on the US Department of State Transnational Organized Crime Rewards Program and was reportedly killed by state security services in early October 2023. The remaining shares in the plant have been passed to its workers and the government further said that it intends to upgrade the site.
The cement sector in Kyrgyzstan is modest and in need of modernisation. It appears to be having a resurgence at the moment though with production mounting and at least two major plant projects underway. The country is in a compelling position economically and geopolitically given its membership of the Russia-backed Commonwealth of Independent States (CIS) and its proximity to China. Various projects backed by the latter’s Belt and Road Initiative, both underway and forthcoming, would certainly appear to benefit from more efficient local cement production and higher volumes.
Brazilian cement sales to fall in 2023 before rising in 2024
30 November 2023Brazil: The Brazilian National Cement Industry Association (SNIC) has forecast a drop of 1% year-on-year in cement consumption in Brazil during 2023. This is due to a slowdown in the residential construction sector, which accounts for 70% of national demand. SNIC forecast a 2% year-on-year rise in cement demand in 2024, due to increased infrastructure activity.
Brazil produced 52Mt of cement during the first 10 months of 2023, down by 2.1%. The country produced 61Mt of cement in 2022, corresponding to a capacity utilisation rate of 65%.
Building codes and low-embodied carbon building materials
15 November 2023Last week the US General Services Administration (GSA) announced that it was investing US$2bn on over 150 construction projects that use low-embodied carbon (LEC) materials. The funding is intended to support the use of US-manufactured low carbon asphalt, concrete, glass and steel as part of the Inflation Reduction Act. For readers who don’t know, the GSA manages federal government property and provides contracting options for government agencies. As part of this new message, it will spend US$767m on LEC concrete on federal government buildings projects following a pilot that started in May 2023. The full list of the projects can be found here.
This is relevant because the US-based ready-mixed concrete (RMX) market has been valued roughly at around US$60bn/yr. One estimate of how much the US federal government spent on concrete was around US$5bn in 2018. So the government buys a significant minority of RMX in the country, and if it starts specifying LEC products, this will affect the industry. And, at present at least, a key ingredient of all that concrete is cement.
This isn’t the first time that legislators in the US have specified LEC concrete. In 2019 Marin County in California introduced what it said was the world’s first building code that attempted to minimise carbon emissions from concrete production. It did this by setting maximum ordinary Portland cement (OPC) and embodied carbon levels and offering several ways suppliers can achieve this, including increasing the use of supplementary cementitious materials (SCM), using admixtures, optimising concrete mixtures and so on. Unlike the GSA’s approach in November 2023 though, this applies to all plain and reinforced concrete installed in the area, not just a portion of procured concrete via a government agency. Other similar regional schemes in the US include limits on embodied carbon levels in RMX in Denver, Colorado, and a reduction in the cement used in RMX in Berkeley, California. Environmental services company Tangible compiled a wider list of embodied carbon building codes in North America that can be viewed here. This grouping also includes the use of building intensity policies, whole building life cycle assessments (LCA), environmental product declarations (EPD), demolition and deconstruction directives, tax incentives and building reuse plans.
Government-backed procurement codes promoting or requiring the use of LEC building materials for infrastructure projects have been around for a while in various places. The general trend has been to start with measurement via tools such as LCAs and EPDs, move on to government procurement and then start setting embodied carbon limits for buildings. In the US the GSA’s latest pronouncement follows on from the Federal Buy Clean Initiative and from when California introduced its Buy Clean California Act in 2017. Outside of the US similar programmes have been introduced in countries including Canada, Germany, the Netherlands, Sweden and the UK. On the corporate side members of the World Economic Forum’s First Movers’ Coalition have committed to purchasing or specifying volumes of LEC cement and/or concrete by 2030. Examples of whole countries actually setting embodied carbon emissions limits for non-government buildings are rarer, but some are emerging. Both France and Sweden, for example, introduced laws in 2022 that start by analysing life-cycle emissions of buildings and will move on to setting embodied carbon limits in the late 2020s. Denmark, Finland and New Zealand are also in the process of introducing similar schemes. The next big move could be in the EU, where legislators are considering embodied carbon limits for building materials as part of its ongoing revisions to its Energy Performance of Buildings Directive or the Construction Products Regulation legislations. Lobbying, debate and arguing remains ongoing at present.
To finish, Ireland-based Ecocem spent a period in the 2010s attempting to build a slag cement grinding plant at Vallejo, Solano County, in the San Francisco Bay Area of California. The project met with considerable local opposition on environmental grounds and was eventually refused planning permission. The irony is that slag cement is one of those SCM-style cements that Marin County, also in the San Francisco Bay Area, started encouraging the use of just a few years later. Ecocem held its inaugural science symposium in Paris this week. A number of scientists who attended the event called for existing low carbon technologies to be adopted by the cement and concrete sectors as fast as possible. One such approach is to lower the clinker factor in cement through the use of products that Ecocem and other companies sell. A point to consider is, if Marin County’s code or the GSA’s recent procurement directive came earlier, then that slag plant in Vallejo might have been built. Encouraging the use of LEC building materials by governments looks set to proliferate but it may not be a straightforward process. Clear and consistent policies will be key.
