Our story
Our mission is to meaningfully impact climate change at scale, by developing gigatonne-level greenhouse gas (GHG) mitigation solutions for global industries and governments that are committed to averting climate disaster and acting for a net zero world starting now.
The founders set the initial focus on methane—one of the most potent GHGs—because aggressive methane mitigation is the best way to maximize positive climate impact. Meanwhile, research had shown that up to 90% of enteric methane from cattle—a major source of global methane emissions—can be prevented with tiny amounts of Asparagopsis seaweed.
Today, CH4 Global is harnessing the power of Asparagopsis seaweed to combat climate change. Steve Meller, CEO and co-founder, leads a team of global business veterans with expertise in turning ambitious ideas into successful, fit-for-purpose products. Teams in Australia, where Asparagopsis is native, are helping transform the region into ground zero for worldwide sustainable production of Asparagopsis.
In 2023, we introduced Methane Tamer™, our revolutionary methane-reducing feed supplement formulation targeted for beef feedlot cattle. Even if adopted for only 10% of cattle worldwide, Methane Tamer would deliver more climate benefit than decommissioning 50-100 million fossil-fueled cars (measures using GWP 100 or 20).
Working together with our partners, we are advancing toward our target of reaching 150 million cattle—10% of the world total—which will prevent the emission of 1 gigatonne of CO2 equivalent over the next ten years.
Sustainability begins at home.

AUSTRALIA
A CH4 Global subsidiary, CH4 Australia is pushing the boundaries of aquaculture innovation in Australia and rapidly building capacity to supply high-quality Asparagopsis seaweed for our formulated animal feed products.
To develop our understanding of growing and processing Asparagopsis, CH4 Australia has facilities in Arno Bay and Green Patch as well as manufacturing in Lonsdale outside Adelaide. The team in Australia is also pioneering the CH4 Global EcoPark concept at our location in Louth, advancing seaweed aquaculture as a primary industry for South Australia.
