One important aspect of sustainable animal agriculture research is the ability to quantify results. The EPA Emissions Inventory is a tool that we use to determine which greenhouse gas emissions are contributing the most to warming from agriculture. 

What is the EPA Emissions Inventory?

The EPA Emissions Inventory is essentially a yearly report of greenhouse gas emissions and sinks. The three primary greenhouse gas emissions reported in this inventory (because they are the greatest contributors to warming) are Carbon Dioxide, Methane, and Nitrous Oxide. These gases are ranked by Global Warming Potential (GWP100), where they are compared to Carbon Dioxide (pounds of a specific gas compared to 1lb of CO2). We use these numbers and comparisons to guide our research so we know which types of emissions to try to mitigate as we strive to reach NetZero.
