AgNext leads cutting-edge research to directly measure and mitigate greenhouse gas emissions from livestock systems. With a particular focus in reducing enteric methane, our team deploys advanced sensor technologies and field-based data collection across diverse production environments generating high-resolution, science-based emissions data critical to evaluating and improving the environmental footprint of animal agriculture. These efforts are building a robust, transparent baseline to inform methane mitigation strategies, support carbon market access, and position producers as credible contributors to climate solutions.
