    Reducing the footprint

    Food companies are looking to reduce their climate impact.

    Yara has documented that low-carbon fertilizer and best practice application tools can cut the carbon footprint of crop production by half. Yara’s solutions are attracting strong interest from food companies looking to reach ambitious climate targets.

    Ambitious target

    PepsiCo UK & Ireland launched its ’50 in 5’ program in 2010.

    The company aims to reduce the carbon and water impact of its core crops by 50% from 2010 to 2015. PepsiCo is working in partnership with its UK growers – 350 in all – to reach the ambitious target.

    Crisp focus

    Potato is the primary point of interest.

    PepsiCo’s range of Walkers Crisps – ”made from good old British spuds” – has been identified as a target market. Each year, PepsiCo consumes about 370,000 tons of potatoes for its Walkers Crisps, making it the largest buyer of UK spuds.

    Pinpointing emissions

    Most GHG emissions occur on the field.

    In 2007 analyses revealed that growing potatoes and sunflower accounts for one third of the total carbon footprint of each bag of Walkers Crisps. Fertilizers were responsible for a substantial part of the GHG emissions from growing PepsiCo’s potato crops.

  • Potato partnership

    Potato partnership

    PepsiCo has partnered with Yara to find low-carbon fertilizer solutions for potato.

    In 2010 the two companies, under the guidance of Cambridge University Farm, evaluated Yara’s recommended crop nutrition program. Field evaluations proved the efficiency of Yara’s low-carbon nitrate fertilizers.

  • Successful results

    Successful results

    Yara’s crop nutrition program lived up to promises.

    It showed a 27% smaller carbon footprint than standard fertilizer practices with no significant differences in yields. PepsiCo now actively promotes low-carbon fertilizer to its growers, endorsing Yara’s nitrate fertilizers from low-emission plants.

  • Joint effort

    Joint effort

    PepsiCo has a long-standing relationship with UK potato growers.

    The company helps farmers use the Cool Farm Tool to calculate farm- and crop-specific carbon footprint, enabling them to make effective changes on the farm. PepsiCo also urges farmers to develop individual long-term carbon reduction plans.

    Closing target

    Yara has a high standing among potato growers in the UK.

    As the benefits of low-carbon fertilizers become apparent at farms across Britain, Yara is looking to increase its market share while helping PepsiCo and its growers bring the ’50 in 5’ target closer.

  • Creating impact

    Creating impact

    More and more food companies are pursuing ambitious sustainability targets.

    Yara has the knowledge and solutions to bring these targets within reach, adding value along the value chain – creating impact.

    Promising potato partnership

    Yara’s innovative catalyst technology has reduced emissions from production and resulted in nitrate fertilizers with a very small carbon footprint.

    Yara’s breakthrough catalyst technology – a small and efficient pellet – is cutting greenhouse gases from fertilizer and food systems worldwide.

    In a 2012 report the Consultative Group on International Agricultural Research (CGIAR) concluded that food systems could be responsible for up to one third of all man-made GHG emissions in 2008. Agricultural production, including land use change, accounted for as much as 86 percent of emissions from the food system.

    “It’s a real kick to develop something of such huge environmental proportions.”

    Factories and fields

    Yara’s catalyst technology is curbing emissions from both factories and the growing of food. It was developed to reduce emissions of nitrous oxide N2O from production of nitric acid, the basis for nitrate fertilizers. Commonly known as laughing gas, N2O is a highly potent greenhouse gas (GHG); its global warming potential is about 300 times that of CO2. Yara’s catalyst technology reduces emissions of N2O by 90 percent – or more. This has cut overall emissions from Yara’s plants by roughly half since the first installation in 2002.

    “It’s a real kick to develop something of such huge environmental proportions. Our technology raises the bar, not only for fertilizer producers,” says David Waller, Chief Engineer at the cradle of this breakthrough innovation, Yara’s Technology Center in Porsgrunn Norway: “The benefits extend to the field. We’ve made our nitrates the fertilizer of choice for climate-conscious growers.”

    Smaller footprints

    His words are more than just a quick claim. Yara’s low-carbon nitrate fertilizers are drawing interest from food companies aiming at improved environmental footprints. Combined with Yara’s application knowledge and tools, the low-carbon approach is used in projects on oranges and potatoes with PepsiCo, and on coffee in Vietnam with Nestlé.

    The catalyst technology is also the secret behind Yara’s Carbon Footprint Guarantee for fertilizers. Launched in Scandinavia in 2010, it is the world’s first of its kind. An independent third party verifies that the carbon footprint of Yara fertilizers sold in Denmark, Finland, Norway and Sweden is below 3.6 kg CO2 equivalents per kg nitrogen. This is less than half of the footprint of untreated production.

    True innovation

    “It is a true case of innovation,” Waller says of the development of the catalyst, which took ten years and about NOK 200 million in investments. He explains that the team of researchers harvested ideas from many different disciplines to achieve the end result: a small green-grayish pellet containing a cobalt compound in a cerium oxide. When placed in the burner basket in a nitric acid plant, the cobalt splits N2O into harmless nitrogen and oxygen.

    Yara made the first full-scale installation of the catalyst pellets in 2002. Since then the technology has been implemented in all of Yara’s nitric acid plants. In addition, it is offered commercially to other producers, representing an annual GHG savings potential equivalent to 100 million tons of CO2.
