Making Riverford sustainable
We want to do better than vague claims and greenwash, so we’ve carried out research with the University of Exeter to learn more about Riverford’s sustainability. From never using air freight, to moving all our fruit and veg into 100% home compostable packaging by the end of 2020, here’s what we’re doing to reduce our environmental impact.

The question of ‘What’s good to eat?’ isn’t a simple one. Our co-owners and customers are concerned about wide-ranging, complex issues of social and environmental sustainability. That’s why we’ve put together our kick-off annual Sustainability Report – it’s packed with brand new research, including a carbon footprint study with Exeter University. We’ll repeat the report every year, to track how we’re doing against last year’s goals and set targets for the year to come.
Read the whole report to find out about our impacts and targets in three main areas: environmental sustainability, Riverford as an employer, and the impacts of our supply chain.
Organic farming is kinder to the planet
The principle behind organic farming is that we should learn from and farm in sympathy with nature, rather than suppressing and dominating it. Organic management:
- Protects natural resources, such as fresh water and healthy soils
- Encourages wildlife; there is up to 50% more wildlife on organic farms
- Avoids pollution from artificial chemicals (we use no artificial pesticides or fertilisers).
- Uses less energy per kg of food produced
- Captures CO2 emissions in the soil through 'carbon sequestration'
Some packaging is a necessary evil. It protects our food, thereby preventing food waste. We can’t do without it entirely, but we have done rigorous research to find the most sustainable solutions.
- All that can be is packed into our veg boxes loose. Luckily, we have ecologically minded customers who don’t mind trimming off a few tatty outer leaves to save a bag.
- Riverford’s veg boxes contain 82% less plastic than the equivalent packaged products from major UK supermarkets*.
- Leave out your cardboard boxes, and anything you can’t recycle at home. We’ll take it back to the farm to reuse or recycle (each box can be used up to 10 times!).
- By the end of 2020, all our fruit and veg will use 100% home compostable packaging. When composted, this packaging biodegrades (breaking down completely into carbon dioxide, water vapour and organic matter, just like a plant decomposing) within a year.
Celebrating UK produce
Across the year, around 80% of our veg is UK grown. 100% of our meat is British.
Sourcing from small-scale organic growers and makers, predominantly from the UK, is really important to our impact on the environment and local economic development. We’re committed to sourcing as much as possible from independent UK producers.
We do our best to inform and enthuse about what’s in season, and to provide the widest range our climate will allow. We extend seasons using polytunnels that don’t use artificial heat or light, and campaign for little-eaten British veg like cardoons and kohlrabi. For those committed to a truly homegrown, seasonal diet, we offer our 100% UK veg box.
Local isn’t always best!
In an ideal world, we would all eat with our local season. In the real world, however: bananas, citrus, a 12-month supply of tomatoes, peppers and apples… These things can’t be grown naturally in the UK, but have come to be viewed as non-negotiable essentials in most households. Given this reality, we’ve done a lot of research to allow us to make intelligent compromises.
There are two options: growing out-of-season produce at home using artificial heat (generated by burning gas or oil), or importation. In the Riverford Sustainable Development Project, Exeter University concluded that importation by road is by far the greener choice.
Take the example of tomatoes. For every kilo of tomatoes grown in a UK hothouse, 2-3 kilos of C02 are released into the atmosphere. When we can’t grow tomatoes at home without heat, we truck over naturally sun-ripened ones from Spain. This uses just a tenth of the carbon – and sun-ripened toms taste better, too.
No air freight
We never use air freight, which causes 40-50 times the C02 emissions of sea freight. When we can’t use sea freight, we transport via road. Driving from Europe isn’t always as far as it sounds; our farm in France, Le Boutinard, is the same driving distance from our Devon farm as the Fens.
The HGV industry has become very efficient: it is now common practice to buy high spec, high capacity trucks, and backload them so they rarely travel empty. Trucking of imports only accounts for 6% of our total carbon footprint; for comparison, our cardboard veg boxes account for 10%.
Home deliveries – more efficient than driving yourself
Most studies show that the final step, to customers’ doors, is the most energy-consuming stage of food’s journey. Although distances are short, loads tend to be small. Exeter University found that because home delivery consolidates many people’s shopping journeys into one, it is generally more efficient than going shopping in your own car.
Riverford compares even more favourably than other home delivery services. We do everything we can do minimise our vans’ emissions…
- Organising routes to minimise distances. We carefully plan our weekly routes to minimise the distance travelled per drop. That’s why you have a fixed delivery day! We may be less flexible than supermarkets which let you choose a delivery time, but our deliveries are many times more efficient.
- Fuel-efficient vehicles. All our vans are Euro 6 compliant (the cleanest diesel vehicles on the road), and use AdBlue, a urea solution added to fuel to further reduce emissions.
- Fuel-efficient drivers. Our drivers are sent on the government-backed SAFE Driver course. This not only improves their safety on the roads, but also their efficiency; some drivers show a reduction in fuel use of 10%.
- Electric vans? We’re trialling the use of electric vans for our deliveries around London as of November 2019, and aim to convert more than 70% of our in-house delivery fleet to electric vehicles.
Fighting food waste
Research suggests that reducing food waste would be the third most effective solution to fighting climate change. So where do we start to address the problem? At the start of the supply chain: on the farm. In the UK, an estimated 2.5 million tonnes of food are wasted on farms every year.
Selling directly to customers means that we can meticulously plan our boxes’ contents a year or more in advance. We grow the amount we expect to need, and that’s it. Few retailers agree, but we think it’s better to occasionally run out than to routinely overproduce.
We also have wider and more forgiving specs for fruit and veg than supermarkets. On occasions when something simply can’t go out to customers (if it’s too ripe, or damaged) our grade-out system finds a good home for it…
- Charity donations. Read about the local charities that enjoy grade-out from the Riverford farms every week on our Charity Partnerships hub.
- Our staff canteens and restaurant. Lots of our grade-out fruit and veg is used in the canteens on our farms, and also dished up at The Riverford Field Kitchen.
- Free veg for staff! Our staff eat well. Not only do they get subsidised meals at work, but they get free fruit and veg to take home too.
- The Riverford Dairy herd. Cows love veg! Who knew? Their favourite is broccoli, but they aren’t so keen on oranges. We can’t give them everything though; beetroot makes their milk pink.
Growing with green power
Since 2007, we’ve bought green electricity from Ecotricity; mostly generated by sun and wind, and currently supplied through the National Grid. Ecotricity’s calculations show that with their help, we’ve prevented around 665 tonnes of C02 emissions in the last year alone. It would take nearly 321,000 trees to absorb that much carbon in the same time.
That’s brilliant – but we would rather someone else bought that green electricity, and we generated our own. We hope that within ten years, with the advance of battery technology, we will be able to generate most of our own power from on-farm wind turbines and solar panels. It will be a challenge – but watch this space.
*Less plastic collectively by weight when we compared the contents of our 3 most popular boxes to the comparable, like for like, packaged produce purchased from 7 major UK supermarkets: Sainsbury’s, Tesco, Asda, Lidl, Aldi, Morrisons and Waitrose. Where the supermarkets didn’t sell the exact same veg, we found as close a comparison as possible (e.g. Riverford Swiss chard vs supermarket pak choi). Please note, box contents change every week and can vary in packaging weight, but we will be running this test every quarter for consistency. The box testing was carried out from March 4th 2019 through to March 25th 2019.
