Essentially there are two steps. The first calculates the carbon footprint, the second, on the back of the information you have provided, benchmarks the findings from the carbon footprint. It is as Easy as 1, 2, 3!!
The first step requires data, the more of which you have the better. However, the model has been designed by experienced environmental management consultants who have enjoyed many years of overcoming the challenges of incomplete data sets so although pristine data sets are most welcome, the model has also been adapted to cope with less than perfect data.
The methodology has been based on high Greenhouse Gas (GHG) Protocol Corporate Accounting and Reporting Standard.
The basic data requirements are energy use and in order to calculate an intensity ratio, the total meter square coverage of buildings, number of full time employees and or turnover. This can be entered over a time period of your choice and as either a total for the company or ideally as a total per facility. The same is true of all other data such as water usage, waste tonnage, business and freight travel, paper usage, IT procurement, catering costs; the list is endless. The tool combines simplicity with an exhaustive reporting structure enabling a comprehensive carbon footprint.
The model applies conversion factors for use by UK and international organisations to report on greenhouse gas emissions. These adhere to the GHG protocol standard ensuring all data can be confidently used within communications to employees, customers and shareholders. See an example report is here.
The second step is the benchmarking. This also requires data but you can breathe a sigh of relief that this data has already been collected. The model uses an amalgamation of data collected by Green Element throughout their many years of environmental consultancy, along with publicly reported emission data from annual reports and in addition the data entered from other users of Compare Your Footprint. All this data is anonymous.
