Our mission is to meaningfully impact climate change at scale, by developing gigatonne-scale 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 and New Zealand, 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 5-year target of reaching 150 million cattle—10% of the world total—on all six habitable continents, which will prevent the emission of 1 gigaton of CO2 equivalent.

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 showcase our cutting-edge platform for growing and processing Asparagopsis, CH4 Australia headquarters are housed in a multi-tenant eco-innovation hub under the aegis of the South Australia Research and Development Institute (SARDI). The team in Australia is also pioneering the rollout of the CH4 Global EcoPark concept at multiple locations, advancing seaweed aquaculture as a primary industry for South Australia.
CH4 Aotearoa is CH4 Global’s subsidiary in New Zealand, where the team works in parallel with their Australian colleagues to supply high-quality seaweed for our Asparagopsis-based supplements to reduce enteric methane in livestock.
CH4 Aotearoa is also rolling out the CH4 Global EcoPark concept, starting with the Ocean Beach land-based aquaculture park followed by several other EcoPark facilities planned over a 5-year period.
