Green Resources & Energy Analysis Tool (GREAT)

Green Resources & Energy Analysis Tool (GREAT) for Cities helps local governments to explore and identify potential energy and emission reduction opportunities and to create action plans for low carbon development. The GREAT Tool for Cities is an integrated bottom-up, energy end-use based modeling and accounting tool for tracking energy consumption, production and resource extraction in all economic sectors on a city, provincial or regional level. The model uses the Long-range Energy Alternatives Planning System (LEAP) software developed by the Stockholm Environmental Institute and includes a national average dataset on energy input parameters for residential, commercial, transport, industry and agriculture end-use sectors.
