Agrecalc facts

What is Agrecalc?

  • Agrecalc is a carbon calculating software, or as many refer to it – farm carbon calculator.
  • But first and foremost, Agrecalc is a Resource Use Calculator.
  • Far from being a tick box exercise, if applied correctly, Agrecalc can show you where you can apply mitigation measures to reduce on-farm costs and boost business profitability.

Who are we?

  • Agrecalc is team of agricultural professionals, environmental scientists and technical developers on a mission to provide clarity and confidence when it comes to GHG emissions.
  • 15 years of experience in calculating carbon footprint; backed by cutting-edge science and research at SRUC and practical knowledge of SAC Consultants
  • We are supporting the transition to low-carbon agriculture, whilst increasing production efficiency.

Agrecalc is a farm carbon footprint tool designed to:

  • Identify the main sources of carbon emissions (CO2 – from fossil fuels; CH4 – from ruminant digestion and manures; N2O – from fertiliser application)
  • Measure those emissions & monitor improvements year after year
  • Benchmark key performance indicators / relevant comparators
  • Account for sequestration – woodland, hedgerows, soil carbon and biodiverse habitats

Why use Agrecalc?

  • ‘Calculate’ option – yearly subscription is FREE for farmers
  • Calculates whole farm emissions, emissions per kg of output and per enterprise
  • No one else handles mixed farms / allocation as well
  • Livestock – most accurate and complete IPCC Tier II method – 15 years of experience
  • Access to benchmark data – no one else provides farmers with access to validated benchmarks
  • Based on scientific credibility of SRUC, and independence and practical reputation of SAC Consulting
  • The only one in the UK that has IPCC soil carbon approved module

What's in it for me?

Understanding your own carbon baseline and the mitigation options allows you to:

Secure Government support:

Anticipate how best to secure grants, subsidies, participation in schemes, and other payments

Secure markets and premiums:

Meet retailer requirements and secure markets and potential premiums for farm products

Reduce input use and cost:

Map your use of inputs, compare efficiency with others, identify costly hot spots where savings can be made

Who is asking for farm carbon audits?


  • Redirecting agricultural subsidies towards low carbon approaches
  • Implementing legislation to drive lower carbon emissions
  • Putting pressure on wider economy / retail sectors – to cut emissions

Processors and retailers

  • Seeking suppliers / farmers to help them deliver low carbon / net zero products to consumers


  • Seeing the benefit of commercial / market advantage

What does the future hold?

October 2022:

  • Module released: Tier II Nitrous Oxide calculations form the UK national Inventory

V 2.0 release in the spring 2023 will include:

  • Nitrification / urease inhibitors

  • Transferred manures

  • Enhanced pig / poultry inputs

  • 3NOP feed additive (Bovaer)

  • Anaerobic digestion of manures

  • Scope 1 / 2 / 3 emission reporting


Further releases will involve: GWP*, agroforestry, peatlands, ammonia, nitrate feed additives, enhanced reporting, and much more!
