CH4 Global

# CH4 Global: High-Level Overview

CH4 Global is a climate technology company that develops seaweed-based feed additives to reduce methane emissions from livestock[1]. Founded in 2019 and headquartered in Henderson, Nevada, the company produces Methane Tamer™, a formulated supplement made from dried Asparagopsis seaweed that reduces enteric methane emissions in cattle by up to 90%[1][2]. The company serves cattle producers, feedlots, and food supply chains globally, addressing one of agriculture's most significant climate challenges—livestock methane represents a potent greenhouse gas that demands aggressive mitigation strategies[2].

CH4 Global's business model combines environmental impact with economic viability. Rather than relying on subsidies, the company operates a proprietary EcoPark cultivation system in South Australia that reduces operational costs by up to 90% compared to conventional seaweed farming[1][4]. This approach enables profitability across the entire supply chain while scaling to meet global demand. The company has demonstrated early traction: major Australian feedlots began feeding Methane Tamer to cattle in 2025, with the product administered at just 0.5% of daily diet[4].

# Origin Story

CH4 Global was founded in 2019 by Dr. Steve Meller (CEO and Co-Founder) and Guy Royal (Co-Founder), with Larry Howell serving as Chairman[2]. Meller brings a distinctive background combining corporate innovation and scientific research—he spent 18+ years in executive positions at Procter & Gamble (including roles in Connect + Develop and Open Innovation) and 17+ years in academic research[5]. After early retirement from P&G in 2012, he founded or co-founded four companies across healthcare, tech, and sustainability sectors while consulting with Fortune 200 companies and governments on innovation strategy[5].

The company's focus on methane emerged from research demonstrating that aggressive methane mitigation offers the best pathway to maximize climate impact[2]. The founders identified Asparagopsis seaweed—native to South Australian and New Zealand waters—as a scientifically validated solution. A pivotal moment came in January 2025 when CH4 Global opened the world's first commercial-scale EcoPark on Eyre Peninsula, marking the transition from development to production at scale[4].

# Core Differentiators

• Proprietary cultivation and processing: CH4 Global has developed a unique EcoPark system that dramatically reduces production costs (up to 90% versus conventional seaweed farming) while maintaining scientific validation and safety[1][4].

• Proven efficacy and scalability: Methane Tamer™ reduces cattle methane emissions by up to 90% with minimal dietary intervention (0.5% of daily feed), making it practical for large-scale adoption[4].

• Integrated supply chain control: The company manages the entire lifecycle—from seaweed inoculum through cultivation, processing, formulation, and end-use with livestock producers[4]. This vertical integration ensures quality and profitability without subsidy dependence[1].

• Strategic partnerships and market traction: CH4 Global has forged partnerships with major organizations to accelerate adoption across diverse supply chains[1][4]. By late 2025, the company had already secured feedlot customers in Australia actively using the product[4].

• Experienced leadership: CEO Meller's dual expertise in corporate innovation (P&G) and scientific research, combined with government advisory experience, positions the company to navigate both technology development and regulatory/policy landscapes[5].

# Role in the Broader Tech Landscape

CH4 Global operates at the intersection of climate tech, agtech, and sustainable agriculture—sectors experiencing accelerating investment and regulatory pressure. Livestock methane represents approximately 14-18% of global greenhouse gas emissions, making it a critical target for climate mitigation[2]. The company's timing is strategic: governments worldwide are implementing net-zero commitments, food producers face supply chain sustainability demands, and consumers increasingly value climate-positive products.

The company's success demonstrates a broader shift in climate tech from subsidy-dependent models to economically viable, scalable solutions. By proving that environmental responsibility can align with profitability, CH4 Global influences how the agtech ecosystem approaches climate challenges. The company's recognition as "AgTech Startup of the Year" (2025 AgTech Breakthrough Awards) and inclusion in TIME Magazine's Top GreenTech Companies (two consecutive years) signals industry validation and positions it as a model for climate-positive innovation[1][2].

# Quick Take & Future Outlook

CH4 Global is poised for significant expansion as livestock producers face mounting pressure to reduce emissions. The company's EcoPark model provides a replicable blueprint for global scaling—additional facilities could be established in key cattle-producing regions to serve diverse markets. Near-term growth will likely depend on regulatory adoption (particularly in carbon credit schemes), supply chain integration with major food producers, and geographic expansion beyond Australia and New Zealand.

The broader trend favoring this company is the convergence of climate regulation, consumer demand, and economic incentives in agriculture. As net-zero commitments become binding rather than aspirational, solutions like Methane Tamer™ transition from innovation to necessity. CH4 Global's challenge will be maintaining its cost advantage and scientific credibility while scaling production to meet global demand—a test that will define whether it becomes a foundational climate solution or remains a niche player. The company's ability to move from early feedlot adoption to mainstream agricultural practice over the next 3-5 years will determine its influence on the broader sustainability landscape.
