Agriculture and farming practices – Grocery

The businesses within our Grocery segment are highly dependent on agricultural commodities and supply chains to deliver both their leading brands and their ESG agenda.

Responsible agriculture, biodiversity and land use

The Grocery businesses have strong links to the global farming sector, sourcing products from crops grown on farms, tea gardens and smallholdings around the world. The approached they take reflect the complexity of supply chains and the nature of their operations.

As they adapt to the evolving regulatory ESG landscape, our Grocery businesses are broadening their approach to managing environmental and social risks, opportunities and impacts in agricultural supply chains. Recognising the critical need for collaboration across the industry, they are working with civil society partners and other industry players to help address supply chain issues.

To help assess environmental risks such as deforestation and biodiversity loss, our Grocery businesses are focusing on specific projects within their most important supply chains. They are also prioritising water reduction and yield increase for certain key commodities such as rice. Climate change is particularly impactful in the supply chains across the division, as extreme weather and natural disasters continue to affect the growth of healthy crops and the livelihoods of the communities that rely on them.

Several businesses leverage third-party certifications from organisations such as the Rainforest Alliance, Fairtrade and the Roundtable for Sustainable Palm Oil (RSPO). Twinings is also actively involved in the International Cocoa Initiative, the World Cocoa Foundation, the Ethical Tea Partnership (ETP), the Sustainable Spices Initiative and the RSPO.

How our Grocery businesses approach responsible agriculture across some of their most material commodities is presented below.

Rice

Traditional rice-growing methods are water-intensive and release a significant amount of greenhouse gases into the atmosphere, accounting for an estimated 8% of global methane emissions. Westmill Foods, a UK based Grocery Group business and leading supplier of food products to the Indian, Chinese and Thai food service sectors, is a founding member of the Sustainable Rice Platform (SRP) and is committed to its standards.

The SRP is a multi-stakeholder partnership established by the United Nations Environment Programme. Through this partnership, Westmill Foods supports initiatives that aim to promote climate-smart agriculture, protect biodiversity, fight climate change and support smallholder farmers. By adopting SRP standards, Westmill helps produce high-quality rice while reducing environmental impact.

In Pakistan, where Westmill Foods sources basmati rice, the business is now in the sixth year of its collaborative project with Galaxy Rice, a key supplier in Pakistan, focused on equipping them with the tools and techniques needed to train their farmers on more sustainable farming methods in line with the SRP standard.

The programme aims to benefit both farmers and their communities, and covers topics such as water management, pesticide management and agribusiness techniques. In particular, it covers the use of water-saving technologies, including land laser levelling and alternate wetting and drying techniques which also help to reduce GHG emissions.

As of May 2025, the project included 1,200 farmers across 75km of land. In 2025, farmers within the programme have seen a 48% reduction in GHG emissions, a 30% reduction in water usage, a 9% increase in net yield and a 26% increase in net income compared to a set of non-SRP farmers.

Westmill has also completed the second year of a similar project working with its supplier Olam Agri to train smallholder Thai Hom Mali rice farmers located in Ubon Ratchathani, Thailand, on the SRP standards. In 2024, this project supported 800 farmers, and achieved a 56% reduction in fertiliser usage and a 12% increase in net income for farmers compared to 2022. Additionally, farmer groups in the project since 2023 achieved a 22% reduction in GHG emissions compared to 2022.

During 2025, Westmill purchased 67% of their basmati rice and 9% of Thai Hommali rice as SRP-certified rice from the projects mentioned above.

Tea and spices

Twinings sources approximately 13,500 tonnes of tea and more than 180 herbal raw materials, including spices. It does not own any tea or herb estates, farms or gardens and is selective about who it sources from, purchasing tea only from Rainforest Alliance certified gardens across seven regions, China, Kenya, India, Sri Lanka, Argentina, Indonesia and Japan.

Its tea supply chain includes approximately 270,000 workers and smallholder farmers. Central to Twinings' responsible sourcing programme is Sourced with Care, which aims to drive positive change through empowering women, supporting incomes and improving living standards within these communities. Through this initiative, Twinings recognises and supports the vital contributions of people and communities in tea and herb production, through programmes which are designed to address issues identified through its Twinings Community Needs Assessment (TCNA) programme. The business also collaborates with key partners in the tea sector, such as the ETP, IDH – the Sustainable Trade Initiative and Rainforest Alliance.

Twinings publishes a sourcing map on its website detailing the tea gardens it buys from, as well as the countries from which it sources its key herbs, as part of its efforts to drive collaboration and greater transparency of reporting.

Twinings has achieved 100% traceability for all the tea it sources. For its 17 key herbs and spices1, it has 94% traceability by volume, back to farm or producer community. Across all herbs and spices sourced, Twinings has reached 85% traceability by volume.

AB World Foods and Westmill are members of the Sustainable Spice Initiative (SSI) and have committed to sourcing 25% of spices in their top three categories among spices, herbs and dehydrated vegetables from SSI-qualified certifications by 2025, rising to 50% by 2030.

Both businesses are making progress towards these targets. In 2025, Westmill sourced 42%of its top three spices (turmeric, chilli and cumin) from Rainforest Alliance-certified sources. AB World Foods sourced 22% of its top three products (coriander, paprika and kibbled onions) from SSI-certified sources. AB World Foods has also set a new target for three additional spices, and from 2025, in addition to the above, it will source 25% sustainably certified material for turmeric, chilli and cumin.

Since 2019, AB World Foods has been working on Project SPICE with partner GRAVIS, a community development organisation in Rajasthan, India, to support rural cumin and coriander farming communities. The project has delivered agronomy and business skills training to over 1,000 farmers, installed rainwater harvesting systems, and delivered wider social benefits to the farming communities including adolescent health education and women’s empowerment. In March 2025, Project SPICE won the Edie Sustainability Project of the Year Award, see more information in our case study.

1.The 17 key herbs and spices are: Apple, Blackberry Leaf, Camomile, Cardamon, Cinnamon, Ginger, Hibiscus, Lemongrass, Lemon Peel, Liquorice, Orange, Peppermint, Rosehip, Rooibos, Spearmint, Turmeric and Vanilla.

Cereals

The Grocery businesses buy around 6% of the UK milling wheat crop which is a core ingredient for Allied Mills, Allied Bakeries, Jordans Dorset Ryvita (JDR), Silver Spoon and Westmill Foods. JDR also sources UK oats and rye.

Jordans Cereals, a premium cereal brand within our Grocery Group, sources some of its grains through the Jordans Farm Partnership, which covers its branded sales volume in the UK and France. This collaboration pays a premium to the farmers involved for their oats, wheat and barley in exchange for them managing at least 10% of their land for the benefit of wildlife. Since 1985, Jordans Cereals has worked with these farmers to promote biodiversity on their land.

Allied Mills ensures all the UK wheat it sources is Red Tractor or TASCC (Trade Assurance Scheme for Combinable Crops) assured. The business is currently five years into its Wheat Sustainability Supply Project, where select farmers adopt techniques that aim to improve soil health and support wildlife.

Silver Spoon, through Allied Mills, is working with four wheat farmers in partnership with Frontier, to source wheat grown using more regenerative agriculture practices. The initiative focuses on crop rotation, soil health, carbon footprint reduction and enhancing biodiversity. This wheat will be used in Allinson’s 1kg Strong White Flour from the autumn 2025 harvest.

Allied Mills and Silver Spoon are supporting nature-positive farming practices among wheat suppliers within their value chain, as part of Tesco’s Nature Programme. The retailer, which is a key customer of those businesses, established a partnership with the Royal Society for the Protection of Birds (RSPB), through which RSPB Farm Advisors deliver farm walks and advisory visits to growers supplying wheat to Allied Mills and Silver Spoon. These visits, coordinated in collaboration with Frontier, are designed to promote habitat interventions that support biodiversity and wildlife, while providing practical advice tailored to the needs of farmers. Potential outcomes include the development of habitat action plans, identifying key opportunities for habitat creation, and identifying relevant funding streams to implement work identified.
