1 Carbon footprinting on farm practical issues and future development

2 SRUC Carbon Management Centre Supports the development of low carbon farming through research, consultancy and education Engages with end user communities, policy makers, retailers and regulators to deliver change 2 2

3 Carbon footprinting on farm - outline 1) Current drivers 2) Practical issues and benefits 2) Future developments 3 3

4 Carbon footprinting on farm current drivers 1) Government regulation nil but coming? 2) Supermarket and consumer demand -? 2) Efficiency and cost savings 4 4

6 Scottish Government - Farming for a better climate; Five key action areas 1. Energy and Fuel use 2. Renewables 5. Optimise livestock productivity 3.Locking in Carbon 4. Best use of fertilisers 6

7 Retailers seeking to lower their supply chain impact - farm main source of carbon SAC-HIE dairy study farm 90% of carbon emissions to supermarket % 91% Negligible 1% 7% Negligible Not calculated 12, kgco 2 e/ tms Farm In transport Packaging Processing (incl. waste) Distribution Consumer SAC - HIE study shows: Beef farms responsible for 98% (20,171kgCO 2 e) supply chain emissions Sheep farms responsible for 95% (23,583kgCO 2 e) supply chain emissions 7

10 Carbon calculators establish a baseline 1) Standards - Kyoto IPPCC - Industry PAS2050 2) Cost vs benefit - Simple tick box exercise quick & easy but little benefit - More detailed and tailored carbon and resource audit valuable management insight/cost savings 3) Unit of measurement - Emissions per farm, per ha, per unit of output? 10 10

11 Free tools available stand alone without technical advice Several now available on web e.g. Cool Farm Tool tailored for potatoes(unilever, McCains), or more general farm estimates e.g. CALM Useful first look see Help meet processor/supermarket tick box requirement Low cost (though can be time consuming). Limited benefit No benchmarking or interpretation Not PAS2050 compliant 11 11

12 Calculations with consultancy advice charges to be met by cost savings More detailed and tailored carbon and resource audit valuable management insight/cost savings Benchmarking Technical Interpretation What does it mean? What can I do about it? How can I save money? PAS2050 compliant e.g. SAC Agric-CARB Carbon and Resource Benchmarking 12 12

13 Government supported footprinting - Farming for a better climate Torr Dairy Carbon Footprint Results The carbon footprints prepared have shown that whole farm emissions and emissions from the dairy enterprise have reduced over the first two years of the project. Year three is still to be assessed CF for year end April 2010 (kg CO2e per kg dwt/kg milk soilds) CF for year end April 2012 (kg CO2e per kg dwt/kg milk soilds) Whole farm Dairy Adopting mitigation measures such as reducing fuel and electricity use, making better use of organic manure and increasing livestock productivity have all contributed to the reduction in emissions found 13

14 Presenting results on farm clear and simple costs and resources not CO2 Provides information to farmers, suppliers and retailers on the C footprint of products PAS2050 compliant Updated using on going research at SRUC and elsewhere 14

15 Results - dairy carbon emissions by source 16% 43% 7% 0% Emissions by activity 6% 28% 0% Power and fuel Purchased inputs Waste Rumination and digestion Livestock manure losses to environment Fertiliser nutrient losses to environment Crop residue losses to environment 15 15

18 Carbon mitigation measures cost/benefit Mitigation options Improving the productivity of current systems Better energy management (energy audits, renewable microgeneration) Changing the systems and livestock numbers Better manure storage and handling Management of carbon sinks and emissions trading Options to improve carbon emissions must be balanced against: economics, other environmental benefits, and socio-economic goals

19 Policy Drivers Future Options Voluntary agreements Information Provision Grants, subsidies, charges, levies and taxes Mix of incentives and penalties Links subsidies and incentives to environmental objectives Carbon tax Cap and trade Price emissions and incentives to find efficient ways to lower emissions Direct Regulation Emissions standards or limits restricting/requiring certain farming practice 19 19

29 Carbon footprinting on farm outlook 1) Government regulation nil, but coming? - Carbon in agriculture too complex to regulate? - Greening of CAP - simple carbon measures only? 2) Supermarket and consumer demand -? - The demand is there, but is the money? - Carbon and cost efficiency go hand in hand 3) Efficiency and cost savings - Move from narrow carbon focus to wider Resource Use Efficiency cost and sustainability - Tangible win-win s pay for themselves - AND meet government policy objectives of - reducing emissions and feeding more people with fewer resources! 29 29
