Greenhouse Gas Life Cycle Energy Emissions Model

To understand the full life cycle of greenhouse gas (GHG) emissions, BOEM has developed the Greenhouse Gas Life Cycle Energy Emissions Model (GLEEM). GLEEM 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.” 

GLEEM was originally a Linux-based model, and BOEM converted the model to a Microsoft® Excel format in 2023. 

The model can be downloaded below, along with a readme file and the model’s technical report. For assistance or questions, please contact gleem@boem.gov.
