3. 50 in 5 Agro sustainability Targets 3 PepsiCo Confidential

4. Key Enablers to getting to our 50 in 5 commitments Connectivity with our growers & committed growers Potato Variety Programme I-Crop Irrigation Efficiency 4 PepsiCo Confidential

5. Reduction of Co2e & H2o (PIUK 50 in 5) Before you can manage you need to measure Carbon (Co2e) per tonne raw potato Water (H2o) applied and rainfall per tonne raw potato We have established the tools: Cool Farm Tool for Co2e Icrop platform (Soil moisture probes and weather stations)

6. 2010 UK I-Crop Field & Hardware Set Up Identification and marking out of 24 trials fields Weather station at each site 3 soil moisture probes in each field 1 probe fitted with a ‘rain gauge’ in each field (to work out the difference between rainfall and irrigation).

7. UK - 24 Fields spread across country, Irrigated & Un-irrigated, Early & Main Crops, Core 3 varieties UK Agro team supported by 3 additional temporary staff to manage the data collection Each field visited every 7-10days

8. Measurement – making it happen: Engage the Growers Adequate Resource - do not underestimate support needed Recognise the differing ability of Growers Collect robust / reliable data

9. 2 sets of yield digs were carried out on each crop, with support of the field team and growers 2 Digs per field area: No 1 dig @ 50-56 days after 50% emergence No 2 dig @ harvest, or as close as possible Yield dig data collected Plant and stem densities Number and weight of tubers, per 10 mm size fraction, i.e.. Yield fractions For 2nd Dig: plus quality (crisp) data 9 PepsiCo Confidential

10. In addition to the 24 trial fields, additional Modified Agronomy trials were conducted 17 trials to study effects of seed rates 14 trials with modified fertiliser usage 10 PepsiCo Confidential

11. Cool Farm Tool Cool Farm Tool Introduced 2009 through Sustainable Food Lab Created by Unilever and University of Aberdeen Wider group of circa 15 companies/multiple crops Simple LCA / Co2 measurement software Agreed to pilot in UK Robin Griffiths – Icrop participant, initial run. PE 2009 data = 111kg/t Vs CFT 2009 data = 110kg/t gave confidence 2010 schedule – 22 crops from Icrop programme Results ex field and throughout storage Nov 2010 – June 2011 11

28. Cool Farm Tool for this crop, excluding storage132 Co2e kgs / tonne raw potato 132 kg / Ha off-the field is high Need to review fertiliser use Field Energy is very low – reviewing data with supplier

29. I-Crop fieldwork results in a growth curve for each crop, from which modelling work can been done ICROP – MVP Daw - Crop growth and Development Full Cover (FC) >90% Canopy No growing days lost on this crop due to canopy falling below 90%

30. Moisture probes showing that this field became very dry mid June. Confirmed by CUF water model. Water usage modelling - MVP Daw –based on i-CROP data Sum Profile Irrigation started too late Soil too dry from mid to end June 116 mm irrigation applied 1 mm drainage 86% water use compared to potential water used Crop received 297mm water in total, but ideally needed 345mm. Needed 164mm irrigation, or 42% more Target : Keep blue line (Act ETp) near green line (Pot ETp) CUF - water modelling – Mark Stalham 17 PepsiCo Confidential

37. PepsiCo have been actively involved with new potato varietiessince the mid-90’s.... 4 distinct phases and can be a 15 yr journey! Years Market volumes &Seed production Grower Engagement “Innovators” Cambridge University Variety Qualification “Advantaged inat least one, not disadvantaged in any vs. targetreplacement variety” Variety programs are a numbers game with no guaranteed outcome.... 80,000 potential candidates 30-40 candidates in small plot trials 2-5 front running varieties 1 qualifiedcandidate .... crossing a large with a small potato does not always result in a medium size potato 20 PepsiCo Confidential
