It takes about
15-30 minutes to get a rough estimate of your carbon footprint by entering
information off the top of your head.
To refine this estimate using information from farm records can take a few hours, as you will need to make sure you collect and enter the data relevant to the scope of the assessment, the info buttons and guidance notes can help you with that an explain what is needed. Don't be put off by the fact that it takes time - it will become easier and more efficient with each new assessment.
You can duplicate an assessment via the “save as” button. Often the most time-consuming part is looking up and estimating the exact kWh and fuel for the given crop from all your electricity and fuel bills or deciding which pesticide rates you applied. Remember that pesticides e.g., only have a small effect on your emissions, so be pragmatic when deciding where to be precise and where to use approximate entries in your assessment. After completion, you may also wish to spend some time exploring options for reducing GHG emissions and making a plan.
