Products

Product

– Carbon Credits – High-quality, permanent carbon removal credits that organizations can purchase to meet their net-zero targets. These credits are based on enhanced weathering and verified through trusted registries. – Insetting Projects – Custom carbon removal initiatives within a company’s supply chain (e.g., agriculture, food, fibre, fuel) to reduce Scope 3 emissions while supporting sustainable practices and product development. – Customer Review – “Eion is the first company that brought a solution to us that, scientifically, we believe can permanently remove carbon, do it with ease, and with little to no disruption whatsoever to the grower base by fitting the way that they’re currently farming.” – Cam Smith, CEO of AGRIgate

Star Product

Eion’s carbon credits are the star product because they offer ultra-high permanence (CO2 storage for 1,000+ years), are scientifically validated through a patented MRV system, and have already been successfully delivered to leading buyers such as Stripe. This positions them as a reliable, scalable solution for companies aiming to meet strict net-zero goals.

Demo Product or Complete Product?

Eion’s initial product offering was Carbon Credits, launched through its enhanced rock weathering (ERW) technology. This approach involved applying pulverized olivine to farmland, accelerating the natural process of CO₂ absorption. The company successfully delivered its first batch of carbon removal credits to Stripe in 2023, marking a significant milestone in validating its ERW method and measurement techniques.
