CH4 Global has been recognised with two international sustainability awards for its seaweed-based Methane Tamer feed supplement, which the company says can significantly reduce methane emissions from cattle. The honours highlight CH4 Global’s growing role in climate-focused livestock innovation.
CH4 Global has won two international awards recognising business sustainability and the impacts being made with its proprietary Methane Tamer feed supplement, which the company says can reduce methane emissions from cows by up to 90 per cent.
Announced in the US, the SEAL (Sustainability, Environmental Achievement and Leadership) Awards recognise the 50 most sustainable companies in the world and the most impactful and innovative environmental initiatives, while also funding research and environmental impact campaigns.
CH4 Global won both the SEAL Environmental Initiative Award for its role in reducing global methane emissions, and the SEAL Sustainable Product Award, for the production of Methane Tamer. The SEAL Environmental Initiative Award honours specific environmental and sustainability initiatives, recognising the efforts CH4 Global has taken to establish the world’s first EcoPark, on Eyre Peninsula, to grow Asparagopsis. When dried and formulated into Methane Tamer and fed to cattle, it significantly reduces the methane emissions in their burps.
The SEAL Sustainable Product Award honours innovative and impactful products that are “purpose built” for a sustainable future, such as CH4 Global’s Methane Tamer. Other major international companies to have been honoured at the 2026 SEAL Awards included British Airways, General Motors, Lenovo, Hitachi Energy and Wolters Kluwer.
FROM SEAWEED TO CLIMATE ACTION
CH4 Global Founder and CEO Steve Meller said that it was an honour to be recognised internationally for the years of effort taken to build a new seaweed industry in South Australia, which was working towards reducing greenhouse gas emissions at a global level.
“It’s rewarding to be recognised for our efforts to bend the climate curve, alongside other major international organisations taking steps to change, whether it be embedding circular economy principles into their activities, recycling plastics, reducing carbon footprints or building living sea walls,” stated Meller. “By growing and drying Asparagopsis, which is native to southern Australian waters, we’re providing farmers with an opportunity to feed their cows a natural seaweed which has an impact on their emissions. Farmers are feeling better about reducing methane emissions, their cows are thriving, and they’ve been able to create a new market for consumers wanting to purchase and consume methane-reduced beef.”
At the Louth Bay EcoPark, CH4 Global is growing and processing Asparagopsis at-scale to formulate Methane Tamer. The company states that when fed to cows at just 0.5 per cent of their daily mix, this product reduces enteric methane emissions from cattle by up to 90 per cent.
CH4 Global last year opened phase one of its EcoPark, where it is growing and processing Asparagopsis in 10 large-scale cultivation ponds with a combined capacity of 2 million litres – capable of producing 80 metric tonnes of the seaweed each year. Beef from cattle consuming Methane Tamer is being sold in butchers and in restaurants in South Australia, with a supermarket chain soon to follow suit.
