Agrecalc - Resource use calculator

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.
  • 16+ 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
  • Suitable for mixed farms and all enterprises
  • Livestock – aligned with the current IPCC Tier II methodology – 16 years of experience
  • Access to benchmark data – provides farmers with access to validated benchmarks
  • Based on scientific credibility of SRUC, and independence and practical reputation of SAC Consulting
  • Option for data and results to be validated by experienced consultants

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?

  • Multiple flocks / herds

  • Fertiliser inhibitors

  • Expanded feed / fertiliser list

  • Transferred manures

  • Enhanced pig / poultry inputs

  • 3NOP feed additive

Read how a Highland farmer lowered his per-kilo-of-output carbon footprint by nearly a third in our Edinvale case study.

Or how an award-winning UK dairy producer, Grosvenor Farms Limited, achieved an average of 16% reduction in carbon emissions over four years.

Maybe you’re a fruit producer who would be interested in how we’ve helped a major Scottish berry grower and packager establish a roadmap of carbon footprint reduction.

Or how we work with a Northern Ireland levy body on developing sustainable farming systems.

As part of the PRISM2030 programme, a Somerset family farm benefited from using Agrecalc to identify improvements and allow for practical recommendations.

In Northern Ireland, a pioneering programme, ArcZero, applied benchmarking in Agrecalc, along with other forward-thinking MRV methods, to demonstrate that agriculture has the capacity to capture, manage and store carbon.
