Step 2. Checking Envirometers for benchmarking

Before you calculate an average Envirometer (that is to say, carry out the benchmark), the Envirometers have to be checked.

Check the Envirometers for completeness, realistic values and missing data. All of this is important to the calculation of the average Envirometer. If you average envirometers for different companies, ask the user to correct and complete data, and to clarify any outliers. 

  1. The following data have to be filled in for the Envirometer to be included in the benchmark. 
  2. The following environmental items concern almost every company. If they have not been completed, the input field should be empty, it is not allowed to be zero. Empty input fields are not included in the benchmark:
  3. In certain sectors, specific waste streams, types of waste water and/or emissions can hardly be zero. For instance, the sludge from the sludge interceptor in garages, specific medical waste from hospitals, or grease from a grease interceptor in buildings with kitchens. It means that if a company has filled in ‘0’ for these waste streams, it is unlikely to be true. Ask the user to complete these data or to mark the items with 'Preliminary data'.
  4. Transport is often (partly) unclear. Ask your contact whether the data are complete. If they are incomplete, you have to take this into account in step 4. Combining Envirometers for benchmarking. Please include only complete data in the benchmark. Mark the other input fields with 'Preliminary data'.
  5. Compare the charts to those of last year (if available) or with the industry sector average, f previous years are not available. Alert the user to inconsistent outcomes and outliers.
  6. Check for all items whether the envirometer includes the right data to calculate the average Envirometer. The Envirometer uses the following 'rules' to decide whether or not a input field is included:

Step 6 is not necessary if you do use standard calculation rules, instead of advanced. Please take into account that in that case the average will include all visible environmental items. Empty input fields and input fields with '0' will be included as 0. Consult the notes on calculating the average Envirometer for other differences between advanced and standard calculation rules.


When finished, please continue with step 3. Importing Envirometers for benchmarking.
