- They were the first retailer to offer recyclable alternatives in their own-brand range saving over 1,000 tonnes of hard-to-recycle plastic each year.
- In 2018, Sainsbury’s came last in a survey of supermarket plastic policies conducted by Greenpeace and was found to have made the least progress on plastic reduction since January the year before.
- In 2019, Sainsbury’s promised to cut just 77 tonnes of plastic packaging, while ASDA achieved 6,500 tonnes of reductions. The average reduction for supermarkets was 2,217 tonnes.

Founded in 1899, Morrisons is the fourth largest supermarket in the UK and has 497 stores in the UK.
- In 2020, Morrisons became the first grocery chain in the UK to eliminate plastic bags from its stores, saving 3,200 tonnes of plastic a year.

Amazon is an American multinational technology company, and the fifth biggest retail shop in the UK. It was founded in 1994.
- Amazon have pledged to be net zero carbon by 2040.
- Rushed packages are often transported on planes rather than cars and trucks, producing a great amount of CO2.
- There are over 100 million subscribers who pay for Amazon prime, which offers next day delivery and free returns. This means more trucks, more planes and more cardboard.
- There has been a 20% increase in cardboard used by Amazon over the last decade.
- If you need something, rather than walking or driving, you just tap or click. That simplicity makes opting for the slower, greener choice even more difficult.
Although prices may be cheaper at supermarkets there are many more reasons why we should shop local. If you care about food waste, using a vast amount of packaging and burning petrol through deliveries… then walking to the local corner shop and doing your shopping there would be an effective start to living a greener life.
