Denmark’s support for Aalborg Portland’s project marks one of Europe’s first large-scale deployments of CCS in heavy industry, tackling the sector’s stubborn emissions and setting a potential blueprint for decarbonising other hard-to-abate sectors.
Denmark has taken a significant step towards making carbon capture a practical part of industrial decarbonisation, with Aalborg Portland winning support in the country’s latest CCS tender for a project that could capture, transport and permanently store 1.25 million tonnes of CO2 a year from 2030.
The scale matters because the cement sector is one of the most difficult parts of the economy to clean up. Industry estimates put cement at roughly 5% to 8% of global CO2 emissions, while a large share of that footprint comes not from burning fuel but from the chemical reaction involved in producing clinker. That makes the sector unusually hard to decarbonise with electrification or efficiency alone.
According to Columbia Business School, more than 80% of cement emissions come from calcination, the process that releases CO2 when limestone is heated to make clinker. McKinsey has similarly argued that around two-thirds of the sector’s total emissions are process-related, which is why carbon capture is increasingly viewed as one of the few realistic options for deep cuts.
That is what makes the Danish decision notable. Aalborg Portland is not being backed for a pilot or a small-scale demonstration. It is being positioned for what would amount to one of Europe’s first large industrial CCS deployments at a cement plant, turning a long-running policy debate into a concrete project with a defined timetable and measurable emissions impact.
The wider significance goes beyond one facility in northern Denmark. Europe’s heavy industries are under pressure to cut emissions while remaining competitive, yet cement demand is still tied to infrastructure, housing, transport and the energy transition itself. That leaves policymakers with an uncomfortable reality: the continent cannot build a low-carbon economy without vast quantities of concrete, but concrete is inseparable from cement emissions unless capture or a major materials shift is introduced at scale.
Statista said the global cement industry emitted about 2.4 billion metric tonnes of CO2 equivalent in 2023, equal to around 6% of global emissions. It also noted that emissions per tonne of cementitious material remain high, underlining the sector’s status as a hard-to-abate problem rather than a marginal industrial issue.
The Danish tender also highlights a broader shift in carbon capture from theory to execution. For years, CCS has been a favourite topic in climate plans and industry roadmaps, but actual projects have often stalled on cost, transport infrastructure, storage certainty and regulatory complexity. Denmark appears to have forced those issues into the open by tying support to a specific industrial installation and a defined emissions target.
That discipline may prove especially important in a market crowded with announcements but short on operating assets. The same tender process also exposed the gap between ambition and delivery, after Gaia Carbon Capture declined an option that could have reduced its bid volume, complicating its previously announced agreement with Microsoft. The episode underlines how quickly the carbon removal and CCS sectors are being asked to move from big claims to bankable projects.
There is also a strategic lesson here for the rest of Europe. If Aalborg Portland succeeds, it could become a template for other cement producers, as well as for steel, chemicals and waste-to-energy plants facing similar decarbonisation challenges. If it fails, sceptics of CCS will have fresh ammunition. Either way, Denmark has chosen to test the technology where it is most needed and where the economics are toughest.
What was once discussed mainly as a controversial climate option is starting to look more like industrial infrastructure. For a sector as carbon-intensive as cement, that may be the most important change of all.

- https://business.columbia.edu/insights/climate/cement – The cement sector accounts for approximately 5–8% of global CO₂ emissions, with emissions more than doubling since 2000. Over 80% of these emissions result from the calcination of limestone in clinker production, an emission-intensive process with no easy substitute. As demand for cement continues to grow, reducing its carbon footprint is a critical challenge. Key decarbonization strategies focus on reducing clinker use, developing alternative chemistries, and scaling carbon capture technologies. However, adoption remains slow due to cost, infrastructure constraints, and regulatory uncertainty. The key question is: How can the industry accelerate the transition while maintaining performance and affordability?
- https://www.statista.com/topics/11056/cement-industry-emissions-worldwide/ – In 2023, the global cement industry emitted 2.4 billion metric tons of carbon dioxide equivalent (GtCO₂e), or six percent of total global emissions. If it were a country, it would be the world’s fourth-biggest emitter of greenhouse gases. With demand growing, cement’s substantial carbon footprint is set to soar further. The industry must now find a way to cut emissions from this hard-to-abate sector while also catering to the world’s increasing urbanization and construction needs. Cement production is incredibly carbon-intensive, with an average of 580 kilograms of CO₂ emitted per metric ton of cementitious material. The largest source of production emissions is clinker – the primary component of cement.
- https://www.mckinsey.com/industries/chemicals/our-insights/laying-the-foundation-for-zero-carbon-cement – The cement industry alone is responsible for about a quarter of all industry CO₂ emissions, and it also generates the most CO₂ emissions per dollar of revenue. About two-thirds of those total emissions result from calcination, the chemical reaction that occurs when raw materials such as limestone are exposed to high temperatures. Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO₂ emissions. In the cement-manufacturing process, raw materials are heated to high temperatures in a kiln in a fuel-intensive process known as pyroprocessing. This results in clinker, small lumps of stony residue that are ground to a powder and combined with other ingredients to produce cement.
- https://www.nature.com/articles/s41597-024-04234-8 – The majority of the carbon footprint of the cement industry originates from the decomposition of alkaline carbonates during clinker production. Recent studies have demonstrated that calcium oxides and other alkaline oxides in cement materials can sequester CO₂ through the carbonation process and partially offset the carbon emissions generated during cement production. This study employs a comprehensive analytical model to estimate the CO₂ uptake via hydrated cement carbonation, including concrete, mortar, construction waste, and cement kiln dust (CKD), covering major cement production and consumption regions worldwide from 1930 to 2023. In 2023, the global annual cement CO₂ uptake reached 0.93 Gt/yr (95% CI: 0.80–1.13Gt/yr). From 1930 to 2023, the global cumulative cement CO₂ absorption reached 23.89 Gt (95% CI: 20.47–28.74 Gt), equivalent to 52.32% of the CO₂ process emissions from cement production during the same period.
- https://energyanalysis.lbl.gov/publications/carbon-dioxide-emissions-global – The cement industry contributes about 5% to global anthropogenic CO₂ emissions, making the cement industry an important sector for CO₂-emission mitigation strategies. CO₂ is emitted from the calcination process of limestone, combustion of fuels in the kiln, as well as from power generation. In this paper we review the total CO₂ emissions from cement making, including process and energy-related emissions. Currently, most available data only includes the process emissions. We also discuss CO₂ emission mitigation options for the cement industry. Estimated total carbon emissions from cement production in 1994 were 307 Million Metric tonnes of Carbon (MtC), 160 MtC from process carbon emissions and 147 MtC from energy use.
- https://carbonstorage.io/facilities/accsion-project – Aalborg Portland is developing a large-scale carbon capture and storage project at its cement plant in Aalborg, Denmark to decarbonize one of Europe’s largest cement production facilities. The project aims to capture up to approximately 1.5 million tonnes of CO₂ per year from kiln exhaust gases, targeting near-complete elimination of process-related emissions and enabling the production of low-carbon and carbon-neutral cement products. The CCS facility is being developed in partnership with Air Liquide, which will supply cryogenic-based capture and purification technology capable of delivering high-purity, liquefied CO₂ streams suitable for permanent geological storage. The system is designed to capture up to roughly 95 percent of CO₂ from multiple kiln lines, integrating capture, conditioning, and liquefaction into a single industrial-scale installation. Captured CO₂ will be transported via newly developed onshore pipeline infrastructure to certified geological storage sites in Denmark, forming one of Europe’s first fully integrated inland CCS value chains spanning capture, transport, and permanent storage.
