“More than two-thirds of the packaging in families’ weekly shops is not recyclable,” according to an article published in The Daily Telegraph last month. The article also highlighted the fact that UK supermarkets are responsible for an estimated 800,000 tonnes of plastic packaging every year.
The newspaper conducted a study which looked at four leading supermarkets, Tesco, Morrisons, Waitrose, and Sainsbury’s, and found that 68% of the supermarkets’ packaging was not recyclable or was unclearly labelled.
For all four supermarkets, it was found that own-brand packaging was less environmentally-friendly and less recyclable than some household brands. Additionally, some own brands had no labelling regarding recyclability.
How the supermarkets compared
The four supermarkets were assessed based on the percentage of packaging sold that:
- was non-recyclable
- did not contain any information about its correct disposal
- featured confusing labelling regarding its disposal
The supermarkets were then ranked based on the percentage of their packaging that fell short of the criteria above. Waitrose performed the best by far environmentally, while Tesco was found to be the worst.
1. Waitrose – 60%
2. Sainsbury’s – 69%
3. Morrisons – 70%
4. Tesco – 73%
Separate research conducted by Engaged Tracking and published in The Grocer last year named Sainsbury’s as “the UK’s greenest supermarket”. It measured the amount of carbon emitted by each supermarket for every pound of revenue in 2016.
On that basis, the findings suggested that bottom-placed Iceland produced comparative emissions that were 34% higher than its competitors’ average and twelve times that of Sainsbury’s. Tesco, Asda, Waitrose and Morrisons (in order) completed the top five list.
There are of course further studies. A little inconclusive then, so how do the UK’s best-established supermarkets compare more generally?

The supermarkets’ wider changes include switching their vehicles to greener fuels, using and investing in renewable electricity and cutting the use of energy and water across their operations, removing unnecessary used by dates, shrinking food waste and reducing the amount of waste going into landfill.
