Develops wearable cattle devices that continuously measure enteric methane emissions and catalytically oxidise them, reducing livestock methane output at the source.
Why it's on ClimateTicker
ZELP's core proposition — catalytically oxidising exhaled enteric methane at the animal level — directly targets one of agriculture's largest and hardest-to-abate emission sources, giving it genuine mitigation credibility. However, the company remains an early-stage startup with key efficacy claims (up to 50% methane reduction, 85x GWP impact) sourced primarily from its own materials and EU CORDIS project summaries, with no published independent peer-reviewed validation found. Investors such as Collaborative Fund, Novo Holdings, Danone Manifesto Ventures, and the Bill & Melinda Gates Foundation lend credibility, but at-scale commercial deployment and verifiable impact data are still outstanding.

Controversy & Greenwashing Watch
ZELP's headline claims of up to 50% methane mitigation and an 85x GWP reduction factor are sourced exclusively from company materials and partner communications; no independent, peer-reviewed study has been publicly published to validate these numbers at commercial scale.source ↗
A right-wing French MEP raised animal welfare concerns about cattle masks in the European Parliament in early 2024, prompting the EU Agriculture Commissioner to clarify that the Commission has no plans to mandate such devices.source ↗
A University of Oregon law review comment analysed ZELP's device under US animal cruelty statutes, identifying scenarios (restricted breathing, entanglement, ill fit) where use could potentially constitute cruelty, while noting final design and independent efficacy testing were still unknown at time of writing.source ↗
