  • Excel based tool Seven input sections: general information, Crop management, sequestration, livestock, field energy, primary processing, transport.Instant results in graph and table format
  • Part of PepsiCo’s ‘50 in 5’ initiative which aims to halve the carbon footprint of agricultural production within five years, including potatoes for Walkers CrispsAlready trialled with over 50 growers-Results shown to be comparable to other studies adding credibility and robustness to the Cool Farm tool.Carbon Trust – performed an LCA study as part of on-pack labeling schemePE International – using Gabi LCA softwareCool Farm Tool roll out – 2010 and 2011 (Euro crops)
  • Leading food businesses and international organizations teamed up to estimate the greenhouse gas footprint of specific farming systems and talk with farmers to figure out how to reduce that footprint as rapidly  and efficiently as possible. Used the CFT to engage with farmers in a consistent way. Collected a large amount of farm-level GHG data from a number of farming systems. Context specific data provides detailed insights and understanding of the variability between different systems and geographies.Image shows some of the locations where the CFT was piloted.
  • A number of companies and groups were involved in this piloting of the toolCovering a range of farming systems across the world
  • In 2012, Unilever, Pepsico, Marks & Spencer, Yara, Tesco, Sustainable Food Lab and the University of Aberdeeen came together to create the Cool Farm Institute, an independent not-for-profit organisation to further develop, promote and distribute the Cool Farm Tool.  The Cool Farm Institute brings together growers with multinational food companies, NGOs, and academics to measure the potential for agricultural practices to mitigate global greenhouse gas emissions.

    1. 1. The Cool Farm Tool Jon Hillier
    2. 2. The context• We know about emissions from agriculture in general• We know about general mitigation options• Not at farm or site level
    3. 3. Greenhouse gas (GHG) emissions from agriculture
    4. 4. Much of retailers GHG emissions are often in the upstream agricultural supply Walkers carbon chain footprint (PepsiCo)What to do about it? Unilever 2008 baseline study across 14 countries
    5. 5. How to mitigate? • Numerous possibilities, e.g. – cropland • management agronomy, nutrient management, tillage/residue management, water management (irrigation, drainage), rice management, agroforestry, set-aside, land-use change – grazing land management/ • pasture improvement, grazing intensity, increased productivity (e.g. fertilization), nutrient management,species introduction (including legumes) – management of organic soils • avoid drainage of wetlands – restoration of degraded lands • erosion control, organic amendments, nutrient amendments – livestock management • improved feeding practices • specific agents and dietary additives • longer term structural and management changes and animal breeding • manure/biosolid management • improved storage and handling • anaerobic digestion - more efficient use as nutrient source – bioenergy energy crops, solid, liquid, • biogas, residuesSmith et al, Phil. Trans. R. Soc. B (2008) 363, 789–813
    6. 6. Origins, A We need some software because farmers lack…. utumn 2008 …robust and credible methods for quantifying farm-level GHGs… and …practical tools to identify the most effective emission reduction practices and quantify their effects.Christof Walter, UnileverSustainable Agriculture(now Christof Walterconsulting) Pete Smith, Convening lead author Several IPCC mitigation chapters

    10. 10. The Cool Farm Tool• Farm/farmer-focused GHG calculator• 7 input sections; site data, field management, SOC and perennials, livestock, field and site energy use, transport to & from farm• Site and management sensitive estimate of GHG emissions on farm• Decision support: allows exploration of mitigation
    11. 11. “Off-the-shelf” models adapted for the farmer• Fertiliser – Emissions from fertiliser production (Ecoinvent 2007, EFMA 2011, Bhat 1994) – Nitrous oxide emissions from the soil (Bouwman et al 2002)• Pesticides (Audsley 1998, Green 1987)• Land use change, tillage practice (IPCC)• Cropping rotation (IPCC)• Manure management system, composting etc (IPCC)• Crop residue management (IPCC)• Livestock feed, etc. (Lal 2004, Hiller et al 2009)• Fossil fuel use from machinery (mostly ASABE)• Energy use – e.g. electricity with national/regional emissions factors (GHG protocol)
