What's new in Which? magazine: February 2022

Supermarkets have a responsibility to help reduce our collective environmental footprint - we've crunched the data to find out how well each retailer is doing

Which? magazine is the UK's bestselling monthly, trusted by more than half a million subscribers.

It's packed with reviews, advice, investigations and news - our aim is to make individuals as powerful as the organisations they deal with in their daily lives.

If you're not yet a Which? member, we're offering a sneak peek at the reviews and investigations that are featured in the latest issue.

Which? magazine: February 2022

In this month's Which? magazine, Karen Lawrence and Ellie Simmonds compare the environmental footprints of 11 supermarkets to find the greenest grocer of them all. Our groundbreaking research is the first to compare shops on a range of sustainability criteria, including their first full year of mandatory greenhouse gas emissions reports.

We gathered hundreds of pieces of data to try to compare as precisely as possible how the supermarkets are performing on the three issues of emissions, plastic and food waste.

As part of our investigation, we also looked at food waste and compared greenhouse gas emissions from the supermarkets' entire operations - including stores, deliveries, and warehouses. Our unique analysis has revealed big variations, and can help you make a more sustainable choice.

From the editor

Over the past year or so, we've taken our environmental coverage up several notches, with articles in most issues, including cover stories on the shortcomings of electric car charging infrastructure (April 2021), the future of home heating without gas boilers (October 2021) and the growth of '100% renewable' energy tariffs that aren't as green as their providers like us to think (November 2021). Our Test Lab pages have increasingly featured Eco Buys as well as Best Buys and Don't Buys.

Running through this coverage is a theme - more and more consumers want to make sustainable choices, but they can't do it on their own. Companies can be both heroes and villains. They can either stand in the way - by offering harmful products, by putting short-term profit ahead of long-term progress or by making green claims that don't stand up to scrutiny - or they can be great enablers, using technology and innovation to make green choices easier and more affordable.

In case we ever doubted it, the pandemic has shown how essential supermarkets are to most of our lives, so they're overdue an in-depth analysis of their environmental footprints. We've looked at plastic and food waste in the past, and we do again, but this time we go further, comparing their carbon emissions as well.
