  • CAFRE passes milestone of 750 farm enterprises carbon benchmarked

    Date published: 15 February 2023

    Carbon benchmarking is a process that allows farm businesses to gain an understanding of their greenhouse gas (GHG) emissions. These are comparable across different years and between businesses, provided that the same calculation method is used. Interest amongst farmers to develop their understanding of GHG emissions has grown significantly, particularly in light of recent legislation and policy proposals that focus on improving environmental sustainability.

    MIchael Calvert - Agriculture Technologist.

    The College of Agriculture, Food and Rural Enterprise (CAFRE) has been at the forefront of knowledge transfer to farmers and wider industry on this subject. This commenced with the establishment of a pilot benchmarking project involving participants in Environmental Business Development Groups (EBDGs). In January 2021, the opportunity to participate in carbon benchmarking was opened to all farmers participating in Business Development Groups (BDGs).

    By December 2022, over 500 farm businesses with 750 farm enterprises had taken the opportunity to find out more about GHG emissions within their farm enterprises. All of those producers who completed carbon benchmarking also had the opportunity to avail of a feedback meeting with a CAFRE Adviser to interpret the results and identify what these mean for their business. It is important to note that many of the GHG mitigation actions and technologies currently available (see Table 1) also lead to improved financial performance, a key pillar of sustainability.

    CAFRE are encouraging those producers in BDGs who have not yet availed of the opportunity to complete carbon benchmarking to get in touch with their Adviser. Indeed, for those producers who are already completing a financial benchmarking, the addition of carbon benchmarking will provide an added helpful measure of the environmental sustainability of their farm business.

    The results of each producers benchmarking are confidential and will not be shared with anyone without the express permission of the participating farmer.

    GHG emissions from farm businesses can be grouped into eight categories. Graphs 1, 2 and 3 highlight the contribution of each category to the total GHG emissions for each enterprise. This has been a useful learning exercise for producers, improving their understanding of the sources of emissions, enabling them to prioritise the most effective mitigation practices and technologies for their farm.

    Actions and Technologies

    Once a farm business has received their carbon benchmark report, the guidance from advisers is focussed on four key pillars: management of soil nutrients, land, livestock and energy. Every farm is different and there will be range of opportunities to achieve improvements in each individual case. There are many actions that a farmer can implement but the most common are outlined in Table 1.

    Table 1: Frequently recommended GHG mitigation actions and technologies.

    Improved nutrient management

    • Nutrient management planning:
      • Efficient slurry spreading techniques: LESSE
      • Timing of fertiliser and slurry applications: Spring
    • Use stabilised fertilisers e.g. protected Urea
    • Nitrogen fixation by clover/sward

    Other Benefits:

    • Reduce fertiliser costs
    • Reduced pollution risk
    • Reduced ammonia emissions
    • Increased sward diversity

    Land management

    • Soil management:
      • Maintain good soil structure – avoid compaction
      • Optimal soil pH
      • Soil organic matter
      • Drainage of mineral soils
    • Longer grazing season
    • Woodland / agroforestry creation
    • Hedgerow management and Creation
    • Protecting carbon stores in peatland

    Other Benefits:

    • Improved nutrient uptake
    • Reduce fertiliser costs
    • Reduced pollution risk
    • Reduced ammonia emissions
    • Increased soil carbon sequestration
    • Increased biomass sequestration and benefits to biodiversity and water quality
    • Increased water infiltration

    Livestock management

    • Animal health plan
    • Optimise animal performance:
      • fertility rates, age at first calving
    • Improved genetic selection
    • Targeted feeding: dietary protein

    Other Benefits:

    • Improved productivity
    • Reduce cost of production

    Energy management

    • Insulate hot water systems
    • Use of plate coolers
    • Increase energy efficiency e.g. LED lights, VSD
    • Clean sky lights to increase natural light
    • Renewable energy

    Other Benefits:

    • Reduce costs

    If you are a CAFRE BDG member and you are interested in gaining an understanding of GHG emissions on your farm, please contact your adviser. All carbon benchmarks are confidential and can only be shared with the express permission of the producer.
