Gathering data for the Farm Carbon Calculator is often the most time consuming part of doing your carbon footprint.
This spreadsheet lists every item you can fill in, gives you the units required (e.g. tonnes or hectares), and helpful hints on where to access information.
All data you require for the Calculator relates only to your business, over the previous 12 months (except for capital items, which is anything under 10 years). If it doesn't apply to you, move on to the next item/section/page.
