About ZELP
ZELP is an agricultural technology company committed to creating a sustainable future for agriculture—one that meets the needs of present and future generations, promoting human and environmental health, animal welfare, and social and economic equity.
Our first focus is to develop and scale technology that measures and mitigates methane emissions in the livestock industry. Today, 1.3 billion people rely on the industry for their livelihoods and food security. However, it is the single biggest human-driven source of methane emissions globally, emitting more than both the oil & gas industry and the coal industry.
The deployment of our technologies on a global scale has the potential to drive half the global methane reduction needed by 2030, and to greatly transform the beef and dairy industries.
ZELP was an inaugural winner of the Terra Carta Design Lab, and has received funding and support from the European Commission, Innovate UK, The Global Methane Hub and the Bill & Melinda Gates Foundation.
