For years U.S. livestock producers have been measured against generic global averages that often understate the efficiencies of modern domestic production. The Meat Institute released a report in April 2026 titled Emissions Factors Brief that lays out methods for companies to document actual greenhouse gas footprints instead of relying on broad international estimates. The brief targets how upstream emissions are measured and reported across the meat and poultry supply chain, with the goal of giving producers data that reflect U.S. practices.
The report is presented as a practical guide to help companies ask clearer questions of data providers, select appropriate datasets and build reporting strategies tied to operational realities. It is a core component of the industry’s Protein PACT commitment, which emphasizes transparency and continuous improvement in sustainability performance. The Meat Institute says the brief also identifies current knowledge gaps and areas where coordinated guidance would improve alignment across suppliers and processors.
Meat Institute President and CEO Julie Anna Potts says the brief is written for companies throughout the meat and poultry supply chain. "This report is intended as a practical resource for companies throughout the meat and poultry supply chain to better understand how emissions data are developed, to ask clearer questions of data providers, and to build strategies that reflect their operational realities," she said, adding the document points to where practical guidance could improve alignment. The brief concentrates on the indirect supply-chain emissions known as Scope 3 emission factors for beef, pork and poultry.
Scope 3 focus
The Meat Institute highlights that reported emission-factor values vary widely across proteins because studies use different functional units, geographic assumptions, system boundaries and methods for accounting impacts such as land-use change. That variability can make comparisons misleading when U.S. producers are grouped with less efficient international systems. The brief argues that standardizing metrics and clearly stating system boundaries will improve comparability and credibility for buyers, investors and consumers.
One of the report’s principal recommendations is a shift from generic global averages to high-quality, peer-reviewed Life Cycle Assessment (LCA) data that reflect regional production practices and modern genetics, nutrition and management. By using primary data, companies can more accurately show emissions per pound of product and how operational improvements reduce intensity. The guidelines are designed so member companies can align reporting with established international frameworks including the GHG Protocol and the Science Based Targets initiative (SBTi).
Industry resources
To help companies of all sizes overcome technical barriers, the Meat Institute is creating a resource hub to centralize methodology guidance and curated datasets. That hub is intended to make it easier for suppliers and processors to adopt consistent reporting approaches, document practices, and set measurable improvement targets that feed into corporate sustainability programs. The institute positions the hub as a tool for the industry to move from defending against external criticism to proactively setting benchmarks based on peer-reviewed science.
The brief was released in April 2026 and is available from the Meat Institute’s website at https://www.meatinstitute.org/sites/default/files/documents/MeatInstituteEmissionsFactorsBrief.pdf. It focuses specifically on beef, pork and poultry Scope 3 reporting and provides methodological recommendations, lists current gaps, and outlines where alignment with global frameworks can help U.S. producers report emissions that reflect domestic efficiencies.
