The ICT Energy and Carbon Footprinting tool is an Excel tool designed to help Further and Higher Education (FHE) Institutions estimate the in-use energy consumption, costs and carbon footprint of their non-residential ICT usage. This in turn is used to estimate energy costs and carbon emissions associated with ICT usage. The final results are designed to provide a reasonable estimate of the overall magnitude of electricity/carbon used.

Excel tool which is designed to help Further and Higher Education (FHE) Institutions estimate the in-use energy consumption, costs and carbon footprint of their non-residential ICT usage. The tool uses three variables to calculate an energy footprint:

1. Numbers of devices
2. Power consumption data for individual types of device (watts, either measured or taken from manufacturer’s data)
3. Usage data of devices in a FHE setting (hours/year).

This in turn is used to estimate energy costs and carbon emissions associated with ICT usage. The final results are designed to provide a reasonable estimate of the overall magnitude of electricity/carbon used. Download the files

• User Guide ICT Energy and Carbon Footprinting Tool - Updated August 2009: This spreadsheet contains a summary of the results to date, from different universities and colleges who have used the tool, broken down by category.
• ICT Energy and Carbon Footprinting Tool Updated August 2009
• An updated version of a simple Excel spreadsheet to help estimate the energy and carbon footprint of an institution's ICT estate. This version is designed to be more user-friendly and incorporates feedback from other institutions. At its simplest users need only input the number of ICT devices. The tool is free to use, but a condition of use is that results are reported back to SusteIT (in confidence if necessary).
