Tanzania: The Tanzania Revenue Authority (TRA) has introduced a new digital verification application named Hakiki Stempu, aimed at helping consumers verify the quality of cement products and combat the sale of counterfeit and substandard cement.
Ndositwe Haonga, TRA Director for Internal Affairs, explained that Hakiki Stempu allows the public to check whether the product they are about to purchase is genuine or not by scanning the product to check if it has the right tax stamp. The app also serves as a tool for ensuring that products meet necessary standards and offer value for money.
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.
Cement firms shift to lighter bags for worker health
04 April 2024Mexico: Members of the National Cement Chamber (Canacem) are set to reduce cement bag weights from 50kg to 25kg to comply with NOM-036, according to El Financiero, which aims to prevent and control musculoskeletal and ergonomic diseases in construction workers. The shift affects companies such as Cemex, Cementos Moctezuma, GCC, Cemento Cruz Azul, Cementos Fortaleza and Holcim.
The standard came into effect on 31 March 2024, but Cementos Moctezuma has already started transitioning to 25kg bags. José Barroso, CEO of Cementos Moctezuma, said "Since 2023, Cementos Moctezuma began the transition from 50kg to 25kg bags in all of its packaged product family.” He added "In Mexico, musculoskeletal disorders represent almost half of the occupational injuries, so we are already implementing changes in our plants to operate according to the new standard.”
Furno Materials secures US$6.5m in seed funding
20 March 2024US: Furno Materials completed an oversubscribed US$6.5m seed funding round on 13 March 2023. Subsequently, the start-up unveiled plans for its Furno Brick carbon-neutral modular cement plant, which can use a variety of gaseous fuels. The plant scales on demand, drastically reducing the barrier to entry for local or small-scale cement production.
Furno CEO Gurinder Nagra said “At Furno, we have the ability to produce ordinary Portland cement now, to adapt to a range of gas-based fuels and materials innovations as they emerge and to meet demand where it exists, while still abiding by a shifting regulatory landscape. Our mission is to go the distance by innovating at the heart of cement production and operating as a complement to other technological developments in the cement space. Our cement far exceeds ASTM International standards, a bare-minimum quality threshold. While most companies tout meeting these standards and stop there, we have continued to refine our process and are on target to surpass the even higher commercial requirements set by significantly-sized customers eager for our solution.”
EU: The European Commission has introduced a Draft Guidance document regarding the Free Allocation Regulation (FAR), now expanded to include ‘alternative hydraulic binders’ within the cement clinker benchmark. To qualify for allocation under this benchmark, these binders must meet three specific criteria: they must be used in cement production, not be included in any other benchmark under the European Union's Emissions Trading Scheme (ETS), and must not be by-products of waste or other production processes.
The European Cement Association (CEMBUREAU) has expressed concerns regarding these criteria. Namely, that the proposed changes suggest a shift from a clinker to a cement-based benchmark approach, making current methodologies and regulations inconsistent and impractical, especially as cement production often occurs outside ETS-covered sites. CEMBUREAU also states that some materials like pozzolana and calcined clay, requiring activation by lime or grey cement clinker, do not fit the hydraulic binder definition. Lastly, the association suggests that only materials covered by the standard EN 197-1 should be considered as alternative hydraulic binders, implying that the current definition in the FAR is overly broad and potentially problematic.
Portland Cement Association to join with other industry associations against new particulates standard
04 March 2024US: The Portland Cement Association (PCA)’s Environment and Energy Committee met in Tampa, Florida, to discuss the formation of a new coalition with other industry bodies under the leadership of the US Chamber of Commerce. The PCA said the coalition will take legal action against the US government, following the Environmental Protection Association (EPA)'s introduction of new, lower particulates emissions standards. The association says that the revised standards may lead to layoffs and lower cement and concrete production.
Other items on the agenda for the committee’s biannual meeting include permitting and regulatory reform for carbon capture, utilisation and storage and alternative fuels for cement production.
Ghana tightens cement standards
12 February 2024Ghana: The Ghana Standards Authority has enacted new quality standards for cement products. BNN Breaking News Ghana has reported that the new standards are intended to uphold safety for users of concrete buildings. This will reportedly be accompanied by increased enforcement against substandard products, including the roll-out of a new licensing system.
US: The Portland Cement Association (PCA) has voiced its concerns over the Environmental Protection Agency (EPA)'s newly finalised standard for particulate matter 2.5 (PM2.5). The new standard reduces the level of particulate matter below 2.5μm diameter permitted in flue gas emissions to 9μg/m3 from 12μg/m3. The PCA says that it is concerned that the new rule may restrict US cement producers’ operations and ‘further complicate’ their efforts to achieve net zero emissions by 2050.
President and CEO Mike Ireland said “This new rule strikes at the heart of the US cement industry's ability to deliver on the Biden Administration's infrastructure goals, as it would lead to fewer hours of operation at plants, which would mean layoffs, as well as less American cement and concrete at a time when the country needs more.” He added “The previous EPA standard on particulate matter emissions — arrived at by government officials working with industry — significantly drove down those emissions by 37% over the last 20 years. This downward trend would have continued without the new standard imposed."
However, EPA administrator Michael Stanley Regan said that the updated standard will prevent 4500 premature deaths and 290,000 lost workdays annually by 2032. Regan said “We do not have to sacrifice people to have a prosperous and booming economy.”
Vietnamese cement sales to rise in 2024
02 February 2024Vietnam: Financial management company SSI Securities Corporation says that it expects Vietnam’s cement consumption to ‘bottom out’ in the first quarter of 2024, before recovering ‘gradually’ throughout the rest of the year. Việt Nam News has reported that the anticipated recovery is the outcome of intensified investments in infrastructure by the Vietnamese government, beginning in late 2023. The cement sector also anticipates growing demand from export markets, including Australia, the US, Africa and South and Central America, as it lowers its reliance on exporting to China. Challenges persist in the form of protective measures or stricter standards in other markets, including the Philippines and Europe.
Heidelberg Materials UK achieves updated BES 6001 standard
22 January 2024UK: Heidelberg Materials UK has received certification to the revised BES 6001 standard across its entire business. The Framework Standard for Responsible Sourcing of Construction Products, version 4.0:2023, emphasises sustainable procurement and supply chain engagement, alongside environmental aspects such as biodiversity. It covers products including cement, ground granulated blast furnace slag (GGBFS) and concrete. The producer says that this will help it to secure additional green building certification schemes credits.
Sustainability director Marian Garfield said "We are delighted to have been awarded the 'excellent' level of certification by the Building Research Establishment (BRE), which demonstrates our commitment to sustainability and supporting our customers in our shared net zero ambitions."
