CarbonCure says producers have poured 10 million truckloads of its CO₂-injected concrete

Nov. 24, 2025 — CarbonCure Technologies said the concrete producers using its CO₂-injection systems had made 10 million truckloads of concrete with it. Here's what happened, what it cost, and what went wrong.

Cost and outcome (as of Nov. 24, 2025)

Outcome: CarbonCure says the 10 million truckloads total more than 83.6 million cubic yards (63.9 million cubic metres) and kept "more than 690,000 metric tons of CO₂ out of the atmosphere." (CarbonCure, Nov. 24, 2025)
Cost: The release gave no price. It says a "shared-revenue carbon credit model" helps producers "offset technology costs." (CarbonCure, Nov. 24, 2025)
Scale check: Our arithmetic on the release's own figures comes to about 10.8 kg of CO₂ per cubic metre (690,000 t ÷ 63.9M m³). That's small per load, but large in total.

How it works, per CarbonCure

CarbonCure's systems bolt into existing concrete plants. Captured CO₂ is injected into fresh concrete, where the company says it "instantly mineralizes and becomes permanently embedded," letting producers "decrease cement usage while maintaining the concrete's compressive strength." (CarbonCure, Nov. 24, 2025)

The company calls itself "the world's most widely deployed carbon utilization solution for concrete sustainability," with "hundreds" of injection systems in plants across "more than two dozen countries." (CarbonCure, Nov. 24, 2025)

It translated the CO₂ figure into 161,352 gas-powered cars off the road for a year. By our math, that implies about 4.3 tonnes per car-year (690,000 ÷ 161,352). It also said the concrete could build "a life-size replica of all 30 NFL stadiums, twice." (CarbonCure, Nov. 24, 2025)

What executives said

"Each of these 10 million truckloads represents real results," said Kristal Kaye, interim CEO. Board chair William Holden pointed to demand across "commercial, residential, infrastructure and fast-growing data center construction segments." Vice chair Onne van der Weijde said carbon credits offer "an incentive to accelerate concrete decarbonization." (CarbonCure, Nov. 24, 2025)

The release lists the company's investors as including Breakthrough Energy Ventures, Amazon, Microsoft, Samsung Ventures and Mitsubishi Corporation. In a separate 2024 feature, Microsoft said it "is using CarbonCure at select U.S. datacenters" and has invested through its Climate Innovation Fund.

What else the release claims

CarbonCure said 10 million trucks parked bumper-to-bumper would stretch from New York to Los Angeles "and back — more than 10 times." It describes its product as "a drop-in solution that leverages carbon mineralization to reduce manufacturing costs and improve cement efficiency without changing performance," and says its partners have delivered concrete to "thousands of residential, commercial and infrastructure construction projects." Interim CEO Kristal Kaye said, "Together, we're proving that concrete innovation is not an aspiration for the future. It's happening today, at scale, in communities around the globe." Vice chair Onne van der Weijde credited "forward-thinking concrete producers who gave innovation a chance and quickly realized the value," saying they had seen "how permanent CO₂ storage and cement reductions translate into economic value and emissions reductions." The company cites the Carbon XPRIZE Grand Prize and induction into the Cleantech 100 Hall of Fame, and its full investor list also names Blue Earth Capital, BDC, Taronga Ventures, 2150, BH3 Growth Equity, Carbon Direct and GreenSoil Investments.

What went wrong

No breakdown. The release doesn't say whether 690,000 tonnes is CO₂ mineralized in concrete, emissions avoided by using less cement, or both, and it cites no third-party audit. (CarbonCure, Nov. 24, 2025)
Small per load. About 69 kg of CO₂ per truckload on average (690,000 t ÷ 10 million), by our arithmetic on the company's figures. (CarbonCure, Nov. 24, 2025)
No cement figure. The release says CO₂ injection lets producers "decrease cement usage" but doesn't say by how much. (CarbonCure, Nov. 24, 2025)
Credits carry the economics. CarbonCure ties producer economics to carbon credits, whose value the release doesn't quantify. (CarbonCure, Nov. 24, 2025)
What we don't know yet: how much of the claimed benefit comes from stored CO₂ versus reduced cement, and who verified it.
