This calculator is intended to measure the approximate electricity use, water use and greenhouse gas emissions associated with relatively simple events or multi-day conferences. If you would like to measure the environmental impact of a more complex entertainment event or a professional sports "Jewel event," please complete our consultation request form to obtain customized support.

If you don't see the "RESET CALCULATOR" button above, this means that no previously-entered data has been recorded.

measure first, then balance your use and emissions
