The self-assessment module

Where to look for data

Your business already holds information on its resources coming in and out. Purchasing records can reveal quantities purchased, as well as how much money was spent on different supplies from one year to the next. If figures are not available on waste disposal cost and quantity, counting the number of bags, drums or skips of waste is a good alternative.

Meter readings can reveal how much money was spent on water and energy in recent months and years, and may help identify where or when water and energy are being consumed in your process.

Possible sources of information are listed on below.
