“The tired old narrative of ‘You can’t grow enough seaweed’ [for livestock methane reduction at scale] needs to go away as far as I’m concerned,” says CH4 Global CEO Dr. Steve Meller. “It’s what we do.”

The most viable route to cost-effective production of feed supplements to reduce methane emissions is synthetic chemistry, says Australian startup Rumin8.
Project will “provide capital to farmers in one of the poorest parts of the world through carbon credits,” says Uganda-based agtech partner NileOrbital Aerospace.
“Bioactive compounds in the Asparagopsis armata biomass other than bromoform are responsible for about 40% of the reduction of methane emissions in our study,” say the authors.
“The thing that will be most successful in this market has to be very low cost and very high efficacy. And right now I don’t see how that can be achieved with anything that’s not a synthetic chemical,” says Dr. Tom Williams.
A vaccine is by far the most cost-effective way to tackle livestock methane emissions at scale within a reasonable timeframe, claims Massachusetts-based startup ArkeaBio.
While burping ruminants are one of the leading sources of methane emissions, surprisingly small sums—just $233m according to AgFunder data—have been pumped into startups tackling the problem over the past decade.
Under the deal, CH4 Global will significantly increase the supply of its Methane Tamer supplements to CirPro and feedlot partners HB Rural and Mort & Co.
The first batch of carbon credits generated from methane reduction initiatives Mitti Labs is working on with Indian rice farmers should be issued in the summer of 2025.
GWP100, the default timescale for determining carbon dioxide equivalence (CO2eq), is problematic when it comes to measuring methane emissions, says Aleph Farms.
From seaweed to selective breeding, multiple approaches are being tested to cut methane emissions from belching ruminants. But could editing the genes of the microbes responsible for the problem change the game?
When it comes to methane emissions, most people think of oil, coal, gas and burping cows, says Louise Parlons Bentata at UK-based startup Bluemethane. What they often forget, she says, is water.
Asparagopsis is one of the most promising tools in the enteric methane reduction toolkit, but there are challenges to growing it at scale and establishing tools to deliver a return on investment for farmers, says FutureFeed.
Cutting methane emissions on dairy farms can require significant upfront investment, but who will provide the capital? Danone VP Chris Adamo weighs in…
Methane emissions from agriculture are finally getting more attention, says Nusa Urbancic at Changing Markets Foundation. “But parts of the industry are working behind the scenes trying to derail climate action in the sector.”
Red seaweed (Asparagopsis) is widely recognized as one of the most effective tools for reducing methane production in ruminant animals. The challenge is growing it at scale.
The Australian startup claims its tech can transform the unit economics of growing red seaweed to produce feed additives for livestock methane reduction.
CH4 Global, a startup dedicated to slashing methane emissions from ruminant livestock using red seaweed-based supplements, has announced the first close ($29m) of a $45m series B round.
Australian synthetic biology startup Number 8 Bio has raised A$1.8m ($1.2m) in a pre-seed round to fund a novel approach to cutting methane emissions from animal agriculture.
