Today, Isometric is expanding into Environmental Attribute Certificates (EACs), becoming the first certifier to support carbon removal, superpollutant reduction, and EACs on a single registry.
We're starting with low-carbon materials. Steel and cement production account for approximately 14% of global carbon emissions, making their decarbonization essential to meeting global climate targets. Despite this, the emissions produced per tonne of steel have been increasing since 2020 and for cement since 2015. The technologies to change this exist, from hydrogen-based steelmaking to electrochemical cement production, but they need reliable revenue to deploy and scale.
The problem EACs solve
The challenge for buyers who want to support these technologies is a practical one. First-of-a-kind production facilities are rarely located near demand, and transporting green steel or cement vast distances is neither practical nor efficient. This limits the ability of buyers to fund and accelerate the technologies that industrial decarbonization depends on.
EACs solve this by separating the environmental attribute from the physical product, through a mechanism known as book-and-claim. This enables businesses anywhere in the world to purchase certificates and assign the associated carbon reductions toward their net zero goals, while directly supporting the producers decarbonizing some of the world's hardest-to-abate industries.
Demand for EACs is growing. In the past year, Microsoft has established EAC-based partnerships for low-carbon cement with Fortera and Sublime, and for green steel with Stegra, while Meta has signed with Electra for low-carbon iron. Businesses are also pooling demand collectively, with the Sustainable Concrete Buyers Alliance (SCoBA) and Sustainable Steel Buyers Platform (SSBP) counting Amazon, Google, Meta, and Microsoft among their members.
The infrastructure gap
The market lacks the certification infrastructure it needs. While quality guidelines for low-carbon steel and cement exist, there are no rigorous standards to certify the corresponding EACs against. High-quality certification ensures that environmental claims are real, traceable, and transparent—and that each EAC can only be claimed once. This is the gap Isometric is filling.
Phil De Luna, Co-Founder and CTO of Canadian cement decarbonization company CURA, said:
"The low-carbon cement market has enormous potential, but it won't be unlocked without the trust and transparency that rigorous certification provides. Having a single, science-led standard for environmental attribute certificates, from the same organisation setting the bar for carbon removal, is the step forward the whole industry has been waiting for."
Shona Crawford-Smith, General Manager of independent carbon and commodities data platform, Sylvera, said:
"We have seen growing diversification of demand into lower-carbon commodities and environmental attribute certificates from buyers. It's exciting to see Isometric expand into this space, particularly for green materials such as cement, where registry and system of record infrastructure is critical for the markets to scale."
Andreas Marcotty, Principal for Carbon Strategy at Fortera said:
"As low-carbon commodity suppliers and buyers gain transaction experience in this emerging market, the conversation is now shifting to execution. High-integrity EAC certification and registry infrastructure brings the validation and double-counting controls this market needs to scale with confidence."
What Isometric is building
Isometric is building the first certification standard for steel and cement EACs. Our Registry and AI-powered verification technology are also expanding to support EACs alongside carbon removal and superpollutant reduction, enabling buyers to manage their portfolios all in one place.
In May, Isometric will release a Book and Claim Module, aligned with both ISO 22095-3 and the forthcoming V2 of the SBTi Corporate Net Zero Standard, which will enable the issuance, tracking, and retirement of certificates across low-carbon materials, sustainable fuels, energy, and more.
We built the certification foundation for carbon removal. EACs are the natural next step. Industrial decarbonization cannot happen without functioning markets, and those markets cannot function without a rigorous certifier.
