Aquaculture Systems Operator | SA

CH4 Global is on an urgent mission to create a global aquaculture ecosystem, for Asparagopsis seaweed, to slash methane emissions from ruminant livestock and positively impact climate change.

Climate change is simply the greatest threat facing mankind today. Wouldn’t it be great if there was a solution that can save the planet, slow global warming, and buy the world time for other technologies to kick in.  We believe there is.

Over 20 years methane is 86 times more potent than CO2 at warming the atmosphere.   So, methane emissions have an outsized impact on global warming AND reducing methane emissions can have an outsized impact on helping us solve this crisis.  This was emphasized in the recent report issued by The Climate & Clean Air Coalition that stated “Our best shot to slow climate change.  Cut methane”.  Cows burp methane.  Today the 1.5 billion cows on the planet produce 150 million tonnes of methane per year which is the largest single source of methane globally. If you do the math that’s 12.9 billion (or Gt) CO2-e per year – that’s more GHG output than from the US, the EU and India combined.

At CH4 Global we are on an urgent mission to impact climate change using the amazing seaweed called Asparagopsis.   Adding less than 0.5% of this natural feed additive can reduce the methane output of those 1.5 billion cows. And it works; Asparagopsis has almost 10 years of published, peer-reviewed scientific proof on its ability to interact with the cow's digestive processes to inhibit methane production.  And best of all it can reduce methane emissions more than 90%.

Importantly, CH4 Global is in position to be market-ready and scalable. Our initial efforts are in Australia and New Zealand – the native home of Asparagopsis.   We do all this because: Who wouldn’t want to be a part in enabling the world to address climate change, so we can create a better world for the generations to come.  Join us and help make a difference for the future of our planet.
