Carbon Removal Deals In Q4 2026
September has been a busy month for carbon removal.
In the space of a few weeks, Europe's first full-scale CO₂ storage site has opened, Google has announced its largest carbon removal purchase to date, and Swedish industrial manufacturer Höganäs has signed a ten-year agreement for negative emissions from a local energy company.
The three deals are very different, but together they point to a market that is becoming more focused on actual delivery, long-term contracting and the practical challenges of buying durable carbon removal.
At a glance
- INEOS Greensand — EU's first full-scale CO₂ storage site, with initial capacity of up to 400,000 tonnes per year
- Google + Terradot — 1Mt of methane elimination plus 1Mt of permanent carbon removal
- Höganäs + Öresundskraft — 7,000 tonnes of negative emissions per year for 10 years
INEOS Greensand: storage moves into commercial operation
Led by INEOS Energy with Harbour Energy and Nordsøfonden, Greensand is the first full-scale facility for permanent CO₂ storage in the European Union. The initial phase can store up to 400,000 tonnes of CO₂ per year, with plans to scale significantly beyond that. CO₂ will be transported from Denmark and injected into the Nini West field around 250 kilometres offshore. (ineos.com)
For removal buyers, the significance is the infrastructure. Permanent storage is one of the critical pieces needed to scale technologies such as BioCCS. At the same time, storage alone does not automatically make every tonne a carbon removal. Feedstock, accounting and certification all matter.
Google and Terradot: one deal, two climate interventions
Google's agreement with Terradot covers more than 200,000 hectares of rice farms in southern Brazil.
The deal includes 1 million tonnes of methane elimination by 2030, through Alternate Wetting and Drying irrigation, alongside 1 million tonnes of permanent carbon removal by 2040 through enhanced rock weathering. (blog.google)
The interesting part for buyers is the structure. Instead of treating methane reduction and carbon removal as completely separate purchases, the agreement combines them within the same agricultural system.
It is another example of how carbon procurement is becoming more nuanced, with buyers looking at the timing and type of climate impact alongside the number of tonnes.
Höganäs and Öresundskraft: a model for industrial buyers
In August, Swedish manufacturer Höganäs signed a ten-year agreement with Öresundskraft for 7,000 tonnes of negative emissions per year from the planned CCS facility at the Filbornaverket waste-to-energy plant in Helsingborg.
The agreement totals 70,000 tonnes, with the facility expected to become operational in 2029. Around 45% of the captured CO₂ is expected to be biogenic and eligible for negative emissions accounting under the relevant framework. (hoganas.com)
The deal is interesting because it looks much closer to what many industrial buyers could eventually do: secure a defined volume of durable removals from a regional supplier through a long-term offtake.
What this means for buyers heading into Q4
A few common themes run through these deals. Durable removals are becoming easier to buy, with storage infrastructure now operating in Europe, enhanced rock weathering being deployed at significant scale, and BECCS volumes being contracted years before delivery.
Demand is also starting to spread beyond the biggest technology companies, with industrial and mid-market buyers signing longer-term agreements. For suppliers, that creates more certainty. For buyers, it means some projects may be committed well before the tonnes are ready to deliver.
That makes the buying process more complicated than simply finding a price per tonne. Buyers need to consider delivery risk, certification, permanence, availability and the structure of the deal itself. A spot purchase, forward contract and long-term offtake each come with different considerations.
For buyers heading into Q4 and planning their 2027 procurement, comparing those factors is becoming increasingly important.
That is where Carbon Compared comes in. Our free platform lets you compare carbon credit projects side by side by project type, location and price, alongside independent ratings from BeZero Carbon and Calyx Global. You can then connect directly with project developers through our RFQ tool, with no intermediaries and no fees.
Whether you are comparing biochar with BECCS, looking for tonnes that can be delivered now, or considering a multi-year offtake, Carbon Compared gives you a way to see the market in one place.
