Decoding food labels: sustainability, welfare and food safety

Our A to Z guide to the sustainability, animal welfare and food certification schemes you might find on food packaging.

Scroll down to see an A to Z of common packaging labels, or click view all above to see what's covered in the guide and navigate to a particular label.

Some of these schemes have come under criticism in the past for lack of transparency, conflicts of interest or breaching their own rules. While it’s important to acknowledge this, here we aim to set out what’s out there, rather than comment on the individual merits of, or issues with, each one.

To find out more about recycling food packaging, read our guide on how to recycle in the UK.

Aquaculture Stewardship Council (ASC)

Where you’ll see it: On 17 species of farmed fish, including salmon, shrimp, trout and bivalves (eg scallops).

What is it? The ASC was set up to minimise the main impacts of farmed fishing and to promote fish that have been farmed responsibly and sustainably. A single ASC Farm Standard will come in in 2025 and will include fish welfare.

B Corp

Where you’ll see it: On company websites, but sometimes the logo will be on the product. 

What is it? Any company, from fund management to furniture, can become B Corporation Certified. A B Impact Assessment is done on a company’s impact on its workers, customers, community and environment, as well as requiring a company’s board of directors to balance profit and purpose. B Corp-certified brands include Alpro, Ben & Jerry’s, Bio-D, Danone, Ella’s Kitchen, Patagonia and Toms. Waitrose and Ocado have virtual B Corp ‘aisles’ on their websites so that you can choose from companies that have been certified. You can search for certified companies on B Corporations's website.

Bird Friendly 

Where you’ll see it: On coffee.

What is it? A certification for organic coffee that focuses on bird-friendly habitats. This means that coffee is produced on farms with a shade cover that provides habitat for birds in tropical landscapes. The certification is developed by the Smithsonian Institute which argues that, based on numerous studies, shade-grown coffee production is the next-best thing to a natural forest.

Bonsucro

Where you’ll see it: On food products that use sugarcane as an ingredient.

What is it? Sugarcane can be grown very unsustainably - it can be very water-intensive - and has been a big driver of deforestation. Bonsucro certification covers both farmers and mills as well as the trading side of the supply chain. The production standard means that producers use less water, fewer fertilisers, produce less greenhouse gases and must be signed up to zero deforestation. It also includes some standards around workers' wages and conditions. The chain of custody standard (the supply chain) shows responsible and sustainable trading, and that the supply chain can be traced.

Carbon Trust

 Where you'll see it: Multiple categories of products, such as energy and appliance companies but also food.

What is it?: It shows that a product's carbon footprint has been measured to internationally recognised standards. This will usually be accompanied by claims of how much the product has reduced its carbon over a period of time or has set targets to reduce its emissions. Brands that carry the logo on some or all of their products include Danone, Nestle, Quorn and Wyke Farms.

Cocoa Life

Where you’ll see it: Cadbury’s, Daim, Milka, Oreo, Toblerone (aims to cover all Mondelez brands using cocoa)

What is it? Founded in 2012, Mondelez’s in-house sustainability scheme trains farmers to increase yields and income and adopt good farming practices to protect forests. It also aims to empower workers and combat child labour. Cocoa Life works with the Fairtrade Foundation. It doesn’t offer minimum pricing to producers but has pledged that producers will not be worse off than they would be under Fairtrade.

Cocoa Plan

Where you’ll see it: KitKat, Milkybar, Nesquik, Nestle cereals

What is it? Nestle’s in-house sustainability scheme aims to make cocoa farming more profitable for farmers by providing them with better-yielding cocoa trees and training them to use land sustainably. It also works to eliminate child labour, empower women, and improve transparency in the supply chain. Farmers aren’t offered minimum pricing. Cocoa Plan works with the Rainforest Alliance. The Cocoa Plan label on the packaging will usually be accompanied by the Rainforest Alliance seal.

Dolphin Safe

Where you’ll see it: Tuna

What is it?  The Earth Island Institute monitors tuna fishing to ensure tuna is caught without any chasing, netting and killing of dolphins. The capture and killing of dolphins is only really associated with yellowfin tuna in the Eastern Tropical Pacific as dolphins swim alongside this type of tuna. Other tuna, such as skipjack, may be labelled as dolphin-safe but, in reality, dolphins won't have been endangered in its capture.

EU Organic - Leaf logo

Where you’ll see it: Across all food categories, including meat and dairy.

What is it? The use of this EU Organic logo is optional on UK foods and may be found in addition to other organic certification scheme logos such as Soil Association or OF&G. For a food to be labelled as organic, it must be certified by one of the organic certification bodies, or it is in breach of the law. This is not necessarily the case in countries outside of the UK and EU. For pre-packed food to be labelled organic, at least 95% of the ingredients of agricultural origin must be organic. Products must meet strict criteria around the use of pesticides, fertilisers, drugs and animal welfare. 

Fairtrade

Where you’ll see it: Bananas and other fruit, chocolate, tea and coffee, fruit juice and flowers.

What is it? Fairtrade covers environmental, economic and social standards. It’s the only scheme that currently sets minimum market prices for what farmers and producers are selling to cover the cost of sustainable production, plus it gives them an additional premium to invest in community projects. To be certified, farms also need to have fair working conditions, ban forced and child labour, and meet environmental criteria such as responsible waste management and water use, and minimal use of pesticides.

Free-range

Where you’ll see it: Chicken, eggs, pork products, turkey.

What is it? In the UK, the words ‘free-range’ on packaging cover a variety of standards, and there’s no official free-range logo. For poultry, there is a legal definition of what 'free-range' must mean, but for other livestock, there isn’t. For example, chickens must have access to the outdoors for a minimum of half their lives to be labelled free-range. Free-range pigs are expected to have permanent access to pasture throughout their lives, but this is set by a voluntary industry code. It would be unusual to find beef or lamb labelled as free-range on the packaging, as most UK cows and sheep have some access to pasture. You may see beef and lamb labelled with pasture-fed, however.  

Friend of the Sea

Where you’ll see it: Farmed and wild fish and shellfish, fish oil supplements.

What is it? For fisheries there are rules about overfishing, caps on the number of fish that are discarded back into the ocean and restrictions on bycatch.  For fish farms, standards include minimising impact on the surrounding habitat, and banning the use of growth hormones, genetically modified organisms (GMOs) and child labour. It isn't a common label on UK seafood in supermarkets; MSC or ASC are more common certifications.

LEAF (Linking Environment and Farming) Marque

Where you’ll see it: Fruit and veg, grains, plants, flowers, dairy products and meat.

What is it? This scheme aims to deliver sustainable food and farming. Products carrying the logo operate to sustainable farming standards, for example by managing soil quality, using water and energy efficiently and controlling pollution. Standards are reviewed at least every five years to remain relevant and were updated in Sepember 2023.

Lion Quality

Where you’ll see it: Eggs

What is it? It is primarily a food safety standard that applies to all types of hen systems— caged, barn, free-range, and organic. British Lion mark eggs come from hens that have been vaccinated against Salmonella and are guaranteed British. Eggs will also be stamped with a code that denotes the system the hen is kept in ( = Organic, 1 = Free-range, 2 = Barn, 3 = Cage) and a code that locates the farm where the egg was produced.

Marine Stewardship Council (MSC)

Where you’ll see it: On fish and shellfish caught in the sea.

What is it? It indicates that the fishery is part of a pledge to prevent overfishing and ensure enough fish are left in the sea. The fishery needs to prove that it doesn’t affect other species or ocean habitats. Since August 2019, fisheries also need to show they comply with workers’ rights. All fish carrying the MSC logo are traceable. Certification status can change depending on fish stocks. The scheme doesn’t cover animal welfare.

Organic Famers & Growers (OF&G)

Where you’ll see it: Across all food categories, including meat and dairy.

What is it? The second-largest organic certification body in the UK, after the Soil Association, OF&G certifies more than 50% of organic land. For a food to be labelled as organic, it must be certified by one of the organic certification bodies, or it is in breach of the law. Like all organic certification bodies, OF&G-certified products must meet strict criteria around the use of pesticides, fertilisers, drugs and animal welfare. Livestock will have access to the outdoors for a significant portion of their lives. 

Outdoor bred

Where you’ll see it: Pork products.

What is it? It tells you that pigs are born in systems with outdoor space, then brought indoors for fattening after weaning, while the mother pig continues to live outdoors. There is no official logo.

Outdoor reared

Where you’ll see it: pork products

What is it? It tells you that pigs are born in systems with outdoor space and spend around half their lives outdoors. There is no official logo.

Pasture for Life

Where you’ll see it: Beef, dairy products, lamb (generally found in butchers and farm shops).

What is it? A certification scheme that ensures that the meat or dairy you buy is 100% pasture-fed (grass and forage crops) and has had no grain or commercially produced feed. This usually means the animal will be higher welfare, although meat or dairy labelled with the Pasture for Life logo may also have other welfare labels, such as RSPCA Assured. 

Rainforest Alliance

Where you’ll see it: Coffee and tea, chocolate, bananas and other fruit, smoothies and nuts.

What is it? Like Fairtrade, the Rainforest Alliance scheme covers social, economic and environmental issues. Products that carry this logo must prove they have systems in place to protect the farm’s natural biodiversity and resources. These include restricting the use of certain pesticides, not contributing to deforestation, minimising soil erosion and monitoring how much energy and water they use. Additionally, they must treat workers fairly, not allow child labour and be part of the Global Living Wage Coalition. Unlike Fairtrade, it doesn’t offer a minimum price but there are additional cash payments made to producers for certified crops. UTZ merged with the Rainforest Alliance in 2018 and so the Rainforest Alliance seal replaces the UTZ label.

Red Tractor (Assured Food Standards)

Where you’ll see it: Across all food categories, including fresh produce, meat and dairy.

What is it? A Red Tractor logo means the food you’re buying is British and traceable back to its origin (vital for food safety, as issues can be pinpointed and resolved at source). The standards Red Tractor sets are enforced through monitoring and inspections by an independent body. While some of its welfare standards don’t go beyond legal minimums, Red Tractor has recently launched an enhanced welfare standard for indoor chickens and a free-range label for poultry. 

Round Table on Responsible Soy (RTRS)

Where you’ll see it: Quorn Foods (including the Cauldron brand), Nestle, and most of the major supermarket retailers are members, although products may not carry the logo.

What is it? Soya (soy) beans are the largest-available global source of protein, but the vast majority of the world’s soya crops go to feeding animals. Argentina, Brazil and the USA produce around 80% of the world's soya. Production in Brazil has quadrupled in the past 20 years, causing the destruction of forests and natural habitats as land is cleared to make way for soy fields. However, much of the soy eaten or drunk in the form of an alternative milk in the UK is grown in Europe. The RTRS implements a zero deforestation standard and promotes good agricultural practices that respect the local environment and fair labour conditions. 

Roundtable on Sustainable Palm Oil (RSPO) Certified Palm Oil

Where you’ll see it: Food and toiletries across all categories - palm oil is common in things such as biscuits, bread and spreads. However, the use of the logo isn't very widespread - all the UK supermarkets source RSPO-certified oil for their own brand products, for example, but may not use the logo.

What is it? Palm oil is one of the most efficient vegetable oil crops – palm yields at least four times more oil than alternatives. Its versatility makes it very popular; it’s in around half of all supermarket products. But its popularity has led to huge deforestation. This scheme accredits palm oil that’s been produced sustainably and without causing harm to people or the environment. Some packaging may not use the logo but may state RSPO palm oil as an ingredient. While the RSPO has been the subject of criticism in recent years, it is supported by the Palm Oil Innovation Group (POIG) whose members include Greenpeace and WWF, as well as manufacturers Danone, Ferrero and L’Oreal, which still see the RSPO as the key route to continuing improvement.

RSPCA Assured

Where you’ll see it: Eggs, dairy, farmed fish and meat.

What is it? A welfare certification scheme that ensures that the farms, hauliers and abattoirs used in the production of your food have been assessed to RSPCA’s farm animal welfare standards. This includes the animals having more indoor space, environmental enrichment, as well as limiting transport time and slaughter methods. It does not guarantee that the animal was free-range, as the RSPCA certifies indoor as well as free-range and organic systems. If you are looking for free-range, it will say this on the packaging.

Soil Association Organic

Where you’ll see it: Across all food categories including meat and dairy.

What is it? All food sold as organic in the UK and EU must come from producers registered with an approved certification body. The biggest is the Soil Association, which certifies more than 70% of organic food in the UK. For livestock or animal-derived ingredients, strict criteria include reduced use of drugs, no GM feed, generous allowances for space and guarantees the animal will live free-range for a significant portion of its life. For crops, the use of pesticides is strictly limited, and artificial fertiliser can’t be used.

Vegetarian Society Approved

Where you'll see it: Across a wide variety of foods and meat alternatives.

What is it? Vegetarian foods may just say 'suitable for vegetarians', or supermarkets may use other logo schemes or their own logos, but a Vegetarian Society logo ensures that there are no ingredients in the product resulting from slaughter, only free-range eggs are used, products are GMO-free, and no animal testing has been carried out. The scheme is independently certified. In 2017, the Vegetarian Society launched a Vegan Approved logo, which ensures the product is also free from any animal-derived ingredients.

Vegan

Where you’ll see it: A wide range of foods and meat alternatives.

What is it? There are a number of vegan logos aside from the Vegan Society’s (pictured). Different certification bodies may all have slightly different criteria, but in essence, they examine products to ensure they are free from animal ingredients and testing. The Vegan Society’s strict criteria define ‘animals’ to include all invertebrates, meaning its animal testing policy does not exclude insects, water fleas or any other creatures. Using a vegan logo for a vegan product is entirely voluntary. Some products may state they are ‘vegan-friendly’ or ‘suitable for vegans’. While the law says that consumers shouldn’t be deliberately misled by the use of such terms, the lack of official guidance can lead to minor inconsistencies.
