Using the Calculator

  • Can it be used by all farm types?

    Yes. The Calculator can be used by farmers and growers with livestock, arable, horticulture, etc. This includes farms on any scale, soil type or place in the UK.

  • What's new?

    We have a complete list of what’s different and improved about this version of the Calculator is listed here

  • How long will it take to fill in?

    This depends on how complex your business is and how organised your records are! The longest part is collating your data in the first place, which could take anything from two or three hours to a whole day. However, once you know where to get the data needed, subsequent times are much quicker.

    Filling in data to the Calculator itself is straight forward once you have the necessary data, between around 30 mins and 2 hours.

  • How much does it cost?

    The Farm Carbon Calculator is free to all farmers and growers, and always has been. All you need is a free account.

    For consultants and those who profit out of advice services, we do charge an annual fee. For more details click here.

  • How do you calculate your carbon footprint?

    You need to enter data about your farm business, and through the Calculator we convert this in to a carbon footprint. We ask you for details about the following areas of your farm:

    • Fuels, electricity and business travel

    • Materials, machinery and buildings

    • Cropping and fertility

    • Livestock

    • Inputs (fertilisers and sprays)

    • Waste and recycling

    • Distribution

    • Carbon sequestration in soils and biomass

    Once you have the information, you fill in your data in our Carbon Calculator. To do this follow the instructions in the video on the Calculator home page, or use this guide

  • What will it show me?

    It will show you the total carbon emissions and carbon sequestration, expressed as tonnes of carbon dioxide equivalent (CO2e), percentage of total emissions/sequestration, and the carbon balance of your farm business.

    The results also show full detail of the emissions/sequestration for every item you enter in the Calculator. Live results also appear as you enter in data, enabling you to compare the results of different items.

Research & Theory

  • What are we going to improve in the next version?

    A full list of what’s not included this time and why. All these items we will try to include in the next version of the Calculator

  • What's included/excluded?

    The technical details! The scope of the Calculator is scopes 1, 2 and 3 – meaning it is comprehensive and covers direct and indirect emissions. In IPCC Livestock calculations it covers Tiers 1 and 2.

    PAS 2050 is an international standard for carbon footprinting. We are both compliant and not with this standard. The Farm Carbon Calculator is compliant with the methodology of he PAS 2050 but takes a much broader approach as it includes scope 3 (indirect emissions) and carbon sequestration, neither of which are PAS 2050 compliant.

    We believe that this wider scope of the Calculator means the Farm Carbon Calculator is far more comprehensive and accurate for the user.

FCC Consultancy

  • Do you offer consultancy services?

    We offer consultancy and training services to farmers and growers, organisations, and food chain businesses. This can include interpreting results, verifying data, creating a carbon reduction strategy, or doing soil analysis on your farm. Please see our Services page for more details

  • Receiving advice from us - for farmers and consultants

    There is advice on how to use the Calculator throughout this website ( plus the video here). If after looking through these resources you still can’t find the answers you’re looking for do contact us for advice.

    To assess the meaning of your carbon report and plan a low carbon journey forward we have lots of resources on the FCT website. If you’re a farmer or grower and have specific questions then we will do our best to answer them for you – please contact us.

    If you’re a consultant we are able to give free advice about the technical workings of the Calculator, but to help interpret results of carbon reports and give advice on farmer management plans we would need to charge.

    For consultants using the Farm Carbon Calculator regularly to help their clients we offer packages to enable consultants to use our services and gain from our expertise. We also offer ad hoc advice on an hourly basis, costed at £70 per hour. Please contact us if you would like to engage us in professional advice.
