CH4 Global named one of TIME Magazine’s Top GreenTech Companies

CH4 Global has been named as one of Time Magazine’s Top GreenTech Companies for the second year in a row - in recognition of continued progress towards scaling, including the development of its Louth Bay EcoPark to grow its seaweed-based cattle feed supplement that reduces enteric methane emissions by up to 90 per cent.

The second annual GreenTech rankings, prepared by TIME and Statista, considered more than 4,000 companies and evaluated them based on their positive environmental impact, financial strength and innovative ability. CH4 Global was among 250 companies selected for the award.

CH4 Global’s inclusion in the 2025 ranking highlights the company’s continued progress in scaling Methane Tamer™, its Asparagopsis-based feed additive, which reduces enteric methane emissions from cattle by up to 90 per cent.

The distinction comes just weeks after CH4 Global opened phase one of its Louth Bay EcoPark, on Eyre Peninsula, where it has begun to grow and process 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.

Over the next year, the facility will expand to 100 ponds capable of producing enough Asparagopsis to serve 45,000 cattle per day – a significant step toward meeting demand from CH4 Global's existing commercial partners in Australia and beyond. With additional investment, the facility could eventually expand to 500 ponds capable of serving hundreds of thousands of cattle per day.

“This recognition by TIME Magazine for the second year running underscores the urgency of tackling livestock methane emissions and the effectiveness of our solution at scale,” said CH4 Global CEO Steve Meller.

“The momentum behind our solution is building, and we are on course to deliver gigatonne-scale climate impact within the next decade by making methane reduction practical, affordable and widely accessible.

“In Australia, the CH4 Global team has worked tirelessly to develop the EcoPark and to start growing Asparagopsis at scale, while working with our partners in South Korea, South America, Japan, the Asia Pacific, the UK and the US, to be able to reach as many cows as possible in the coming years as we work to mitigate climate change."

CH4 Global is working to reduce methane emissions from cows, which is naturally-produced in their stomachs and released through burping. Methane is more than 80 times more potent than CO2 in trapping heat in the atmosphere over a 20-year period, making it a critical target of efforts to combat global warming.
