Ruminati is your emissions management partner. We help you accurately calculate your emissions data and provide insights that make a real difference across the entire agricultural supply chain.

Ruminati began with a simple idea: to create something better for producers when it comes to tracking on-farm emissions.
Founded by farmers Bobby Miller and Will Onus, alongside tech expert Peter Leihn, Ruminati was built on the belief that emissions management could be easier, smarter, and more accessible. With guidance from industry experts like Professor Richard Eckard, Dr. Robert Banks, and Richard Rains, we developed a tool that puts producers first, making emissions tracking straightforward and intuitive.
Our emissions calculator and reduction planner make it easy for producers, feedlotters and processors to track and manage their emissions data, but it doesn’t stop there. With simple and secure data sharing options, Ruminati users can also collaborate with corporate partners and support industry-wide action.
We’re not only backed by experts and supply chain leaders, but we always keep producers at the heart of what we do. Our tools aren’t just user-friendly and efficient; they’re built by people who understand the industry because we live it every day. Our values — collaboration, service, proactivity, and respect — drive us to deliver meaningful results, and we’re here to help you turn emissions data into opportunities for growth and sustainability.
