Why we can't ignore product sustainability

Interest in ethical and environmental issues has never been greater. Our reviews need to change. Here’s why we can’t ignore product sustainability.

Which? has been testing products for more than 60 years. With our rigorous reviews we’ve helped generations of consumers make the right choices – no doubt you have a few cherished Best Buys around your house.

As head of product testing, I’m very proud of this wonderful heritage. But we’re faced with a difficult and uncomfortable question.

Are our reviews fit for our times, for our readers today and the consumers who will use Which? tomorrow? The truth can be as uncomfortable as the question.

Sustainability is an increasingly important factor in buying decisions, and we need to respond to this change. In our test labs we’ve developed new packaging tests and piloted repairability assessments, and we’re finding new ways to analyse our reliability data.

Removing and replacing batteries

For example, in cordless vacs tests, we’re rating how easy it is to remove and replace the battery, the availability of spares and the ease of maintenance.

For washing machines and tumble dryers, we’re developing a basic repairability assessment. Among other things, it asks whether you can get the back off a machine – is it ‘screw or glue’?

We’ve also started to record the amount and recyclability of packaging – both in everyday and big-ticket items.

Environmental and corporate social responsibility

There are also calls to assess the practices of the companies behind the products, following the shift in consumerism towards brand values.

Is this trend relevant for us? In a 2018 survey, we asked 1,400 of you whether we should include brand environmental and corporate social responsibility credentials in our reviews. Two thirds of you agreed.

Of course, this doesn’t mean we stop testing. We know the value of our unique Best Buy verdicts. But if we can offer more, from better insights into durability and longevity, to advise on the wider sustainability practices of the brands behind them, that’s an ambition we think is worth striving for.

Should we be doing more? That’s not a question I ask myself. It’s a question I ask the Which? reader of tomorrow – my smart and courageous 13-year-old daughter, with her whole life ahead of her. Her answer? ‘What are you waiting for, dad?’

There is a little relevant information here but nothing about specific equipment that I can see (at a quick glance). https://www.which.co.uk/reviews/new-and-used-cars/article/electric-car-charging-guide/how-to-charge-an-electric-car

The web will show brands but it would be invaluable to have independent test information.

On the topic of sustainability my 28 year old Cannon cooker “gave up the ghost ” in the main oven dept. It was the thermocouple that was blown resulting in just a peep from the gas burner never increasing .
As the chances of spares are not very realistic I was about to say a goodbye prayer over it until I realised its got a smaller top oven, inside is the gas burner for toasting but also a separate burner for the top oven —I had never used it , it was in “brand new ” condition and as I no longer cook chickens/turkeys etc this might do .
The control knob was stiff (well I had never used it ) but it worked magnificently nice bright gas flame and just as adjustable as the main oven, now instead of an hour to heat a small pie from frozen its done in 10 minutes or so , it also has a separate fan from the main oven , I am sure I am doing my bit for sustainability as the small oven is all we need now.
