About GEMIS

GEMIS, or the Global Emission Model for Integrated Systems, is a comprehensive life cycle assessment (LCA) software tool developed by IINAS, the Institute for Integrated Environmental Assessments. The tool is designed to analyse and model the environmental impacts of various technologies, products, and services. GEMIS covers a wide range of sectors, including energy, transport, materials, and agriculture, among others, providing reliable and consistent emission factors.

Methodology description

GEMIS (Global Emission Model for Integrated Systems) is a life cycle analysis-based bottom-up model developed by IINAS (International Institute for Sustainability Analysis and Strategy), designed to determine the environmental impacts of energy, material, and transport systems. The model calculates full life-cycles for processes and scenarios, tracing all stages from resource extraction through to final energy or material use. The GEMIS database covers more than 10,000 processes across more than 50 countries. Results include GHG emissions expressed as CO₂ equivalents, air emissions, cumulated energy demand, and raw material requirements, which can be broken down by individual process or aggregated at sectoral and regional levels. GEMIS covers a wide range of sectors including energy, transport, materials, and agriculture.

    Cornerstone Sustainability Data Initiative

    Cornerstone is a sustainability data initiative that maintains and publishes key US environmental datasets, including the US Environmentally-Extended Input-Output (USEEIO) family of models, and eGRID electricity emission factors, originally developed by the US Environmental Protection Agency (EPA). USEEIO provides open emission factors across more than 400 sectors of the US economy and is widely used for Scope 3 corporate accounting, policy analysis, and academic research. eGRID provides detailed electricity generation emissions data for estimating the emissions intensity of grid-supplied electricity in the United States.
