2025 Year in review: our environmental impact summary
14 January 2026
If there is a way to define 2025, this is it: project expansions, technological advancements, geographical growth, and remarkable progress. Driven by projects and people at the heart of decarbonization. Together with the HoSt Group, we are working towards one mutual goal:
25 million tons of CO₂ savings by 2032.🌱
Across North America, our team delivered a growing portfolio of dairy and also organics-to-RNG, biogas upgrading, and CO₂ recovery projects, each making a tangible contribution to decarbonization. Here are just some of our achievements that capped off 2025:
Oregon. Throughout 2025, HoSt has been working to construct one of the largest dairy-to-RNG projects in the USA. This project will process an estimated 200+ million gallons per year of manure and transform it into 450,000 MMBTU/year of RNG. The annual energy produced by this single project is enough to power an Apollo moon landing mission with 100,000 MMBTU/year to spare. With the leftover energy, we could power another 1,000 CNG fueled vehicles each and every year.
New Mexico. Another milestone of 2025 was the commissioning of two dairy-to-RNG projects in New Mexico. Their combined output will exceed the Northwest project, with an estimated 525,000 MMBTU/year of energy produced. That means that these two projects are offsetting the same Greenhouse Gas emissions as 13,500,000 mature trees. Every. Single. Year.
Arkansas. We’re under contract for a project where we’re delivering two large upgraders and a CO₂ system. The anticipated output is over 2,000 SCFM BUP (1,397,316 MMBTU/year of RNG production), and 4000 kg/hour (33,988 tons/year) of LCO2 production. This CO₂ is no longer being off gassed into the atmosphere, and will instead be recovered, monetized and reused, creating an additional revenue stream for this project.
Michigan. This project has a 747 SCFM capacity BUP (210,000 MMBTU/year of RNG production). The potential impact is around 12,222 US tons CO₂ / year.
Minnesota. This upgrader project has a 350 SCFM biogas capacity BUP (98,500 MMBTU/year of RNG production), avoiding 5,735 US tons of CO₂ annually.
Arizona. We’re installing a LCO₂ system has the capacity to produce ~12,600 US (short) tons of liquid CO₂ per year (1700kg/hr. system). That’s 12,600 tons of CO₂ potentially being saved, recovered, and reused.
Together with our clients, we’re moving the needle on decarbonization—together.
