The Global Negative CO2 Cement Market was valued at USD 1.2 Billion in 2025 and is projected to reach USD 4.5 Billion by 2034, growing at a Compound Annual Growth Rate (CAGR) of 18.7% during the forecast period (2024–2034). This rapid expansion is driven by stringent global decarbonization mandates, increasing green building certifications, and significant technological advancements in carbon capture and utilization within the construction materials sector.

As the construction industry confronts its substantial carbon footprint, cement production is undergoing a revolutionary transformation. Instead of being a primary source of CO2 emissions, cement is now poised to become a carbon sink. In this blog, we profile the Top 10 Companies in the Negative CO2 Cement Industry—innovators, material scientists, and sustainability pioneers who are fundamentally reshaping the future of building materials.

9️⃣ 2. CarbonCure Technologies

Headquarters: Dartmouth, Nova Scotia, Canada
Key Offering: CarbonCure Retrofit Technology, CarbonCure Ready-Mix, CarbonCure Precast

CarbonCure Technologies provides a suite of technologies that inject captured CO2 into concrete during mixing. The CO2 undergoes a mineralization process, becoming permanently embedded and increasing the concrete’s compressive strength. This allows producers to reduce the cement content without sacrificing performance, leading to a lower carbon product.

Sustainability Initiatives:

• Permanent sequestration of CO2 in concrete, with over 30 million cubic yards of concrete produced using their technology

• Partnerships with over 700 concrete plants across North America and internationally

8️⃣ 3. ECOCYCLE (by Hoffmann Green Cement Technologies)

Headquarters: Bournezeau, France
Key Offering: H-UKR, H-EVA, H-P2A clinker-free cements

Hoffmann Green Cement Technologies has pioneered a range of clinker-free, low-temperature cements that result in a negative carbon footprint over their lifecycle. Their ECOCYCLE solution is based on using industrial by-products like flash clay and blast furnace slag, avoiding the energy-intensive clinker production process entirely.

Sustainability Initiatives:

• 0% clinker technology eliminating the main source of cement’s CO2 emissions

• Up to 80% reduction in CO2 emissions compared to traditional Portland cement

---

7️⃣ 4. Brimstone

Headquarters: Oakland, California, USA
Key Offering: Portland cement from calcium silicate rocks

Brimstone is developing a process to make ordinary Portland cement from carbon-free calcium silicate rocks instead of limestone. Since these rocks contain no CO2, their process avoids the fundamental chemical emissions of traditional cement production. The resulting cement is chemically identical to the industry standard but is carbon-negative.

Sustainability Initiatives:

• Elimination of process CO2 emissions from cement chemistry

• Production of valuable mineral by-products that can permanently sequester additional CO2

---

6️⃣ 5. CarbiCrete

Headquarters: Montreal, Quebec, Canada
Key Offering: Carbon-negative concrete masonry units (CMUs)

CarbiCrete has developed a technology for the production of precast concrete products that are carbon-negative. Their process replaces cement in concrete with steel slag and cures the mixture with CO2. The resulting concrete blocks permanently sequester CO2 and are cost-competitive with conventional products.

Sustainability Initiatives:

• Elimination of cement from the production process

• Utilization of industrial waste (steel slag) and CO2 as raw materials

---

5️⃣ 6. Seratech

Headquarters: London, United Kingdom
Key Offering: Carbon-neutral cement using olivine and direct air capture

Seratech has developed a proprietary process that uses olivine, an abundant mineral, to absorb CO2 directly from the air. The resulting silica and magnesium carbonate by-products can be used to create a carbon-neutral or carbon-negative cement. Their solution aims to be scalable and cost-effective.

Sustainability Initiatives:

• Direct air capture integration into cement production

• Utilization of abundant, non-toxic mineral feedstocks

---

4️⃣ 7. Neustark

Headquarters: Bern, Switzerland
Key Offering: Carbon dioxide removal via recycled concrete mineralization

Neustark specializes in capturing biogenic CO2 and storing it permanently in recycled demolition concrete granules. This process transforms construction waste into a carbon sink. The carbonated granules can then be used as a substitute for gravel in new concrete production, reducing both emissions and virgin material use.

Sustainability Initiatives:

• Permanent carbon storage in construction and demolition waste

• Creation of a circular carbon economy for the construction sector

3️⃣ 8. Cemex (Vertua® Series)

Headquarters: Monterrey, Mexico
Key Offering: Vertua® Ultra Zero, Vertua® Classic

Global building materials giant Cemex has launched its Vertua® product line, which includes a range of low-carbon and carbon-neutral concretes. Their Vertua® Ultra Zero product is a milestone, offering a carbon-neutral concrete solution through a combination of optimized mix designs, alternative binders, and verified carbon offsets.

Sustainability Initiatives:

• Investment in carbon capture, utilization, and storage (CCUS) technologies

• Goal to deliver net-zero CO2 concrete globally by 2050

---

2️⃣ 9. Heidelberg Materials (evoCEM)

Headquarters: Heidelberg, Germany
Key Offering: evoCEM, i.CO2MENT project outputs

Heidelberg Materials, one of the world’s largest building materials companies, is actively developing carbon-captured cement products. Their evoCEM is a low-carbon cement that reduces CO2 emissions by over 30%. Through projects like i.CO2MENT, they are scaling up CCUS technology to achieve carbon-neutral cement production.
