To understand the life cycle of greenhouse gas (GHG) emissions, BOEM has developed a model, the Greenhouse Gas Life Cycle Energy Emissions Model (GLEEM). GLEEM is a Linux-based model that estimates GHG emissions from the onshore processing, storage, and distribution of oil, gas, and coal—known as “midstream emissions”—and the consumption of oil, gas, and coal products, or “downstream emissions.”
