The new Which? Investigates podcast explores how we can all be more sustainable consumers and the barriers we often find along the way. We’ll be demystifying the world of green jargon to find out what really matters when it comes to improving our environmental impact.
Reducing your carbon footprint is never quite as simple as it seems. Over the next few weeks, our first podcast season will investigate the ways in which UK consumers have an impact on the environment and where we can make a difference. We’ll be digging into the facts around the sustainability issues that matter, from our energy supplies to our diets, and our cars to our gadgets.
Plus, we’ll be putting common sustainability claims under the spotlight to find out which are actually useful and which are just hot air.
Join science journalist and producer Greg Foot and our own Which? experts as they figure out how we can genuinely reduce our environmental footprint, and what’s simply green-washing.

COMING SOON: After a year of Zoom calls, countless hours sat in makeshift home offices, and less time stuck in commuter traffic, what does the future of work look like?
Will ‘hybrid working’ reign supreme? And is WFH actually be better for the planet?
In this Which? investigation, Greg Foot reckons that with some offices down-sizing and fewer of us travelling to work, the eco-benefits could be huge. He soon learns that it’s much more complex than he thought.
We’ve all heard that flying is terrible for the planet, but is there any chance of it getting cleaner? Can ‘carbon-offsets’ soak up and neutralise your flight’s emissions? And will ‘bio-fuel’ decarbonise the aviation industry?
In this Which? investigation, Greg Foot asks if he can ever justify taking a flight, learns about the benefits and wider impacts of travelling abroad, and uncovers how ‘eco-friendly’ an ‘eco-holiday’ really is.
Homes and heating are responsible for around a fifth of the UK’s carbon emissions. There’s increasing talk of our boilers potentially being upgraded to hydrogen, and increased government interest in heat-pumps as a possible way to reach the net zero target. But what really is the future of your home heating system?
In this investigation, Greg Foot asks if these are indeed viable options for your home or whether their green credentials are being exaggerated. He also looks to Norway to learn about ‘district heating’ and finds out what you should do next time your boiler fails.
This is a chance to hear more from three of the experts we spoke with while recording the first half of season one:
- Materials scientist, engineer and broadcaster Mark Miodovnik reveals more about how your mobile phone is made, how repairable it is (or not), and the shocking reality of what happens if you recycle it (02:22-19:14).
- Journalist and author of ‘Sex Robots and Vegan Meat’, Jenny Kleeman, shares stories of her unique research trips looking at the alternative meat industry (20:45-32:31).
- Which? car expert Adrian Porter answers some of your biggest questions about electric vehicles (EVs) (34.11 – 48.39).
With more and more plant-based burgers, milks and other alternatives filling our shopping aisles, it’s never been easier to cut meat and dairy products from your diet. But as advocates make claims for the health-promoting and planet-saving power of going plant-based, what does the evidence say?
In this Which? Investigation we ask if cattle farming can ever be sustainable, uncover how ‘plant-based’ doesn’t always mean ‘planet-friendly’, and learn how healthy, or not, these meat-alternative products really are.
With the UK set to ban the sale of new petrol and diesel cars by 2030, more of us are considering the switch to electric. But with the environmental impact of making the batteries, and the need to generate the electricity to charge them, what is truly the greenest option – go electric or stick with a petrol or diesel car?
When you buy a new phone, you expect it to last, but could that new handset have a shelf-life that’s shorter than your contract? A cracked screen or a dodgy battery can be a pain to repair, but is that driven by manufacturers or by consumers eager for the latest feature-packed model?
Greg Foot asks who’s to blame for the mountain of ‘old’ mobiles hidden away in drawers up and down the country. Find out what it takes to make a phone, the surprising facts about what happens if you recycle one, and how phone companies may be putting you at risk.
Episode One: is plastic packaging always bad?
The packaging on our everyday groceries is enemy number one for anyone trying to do their bit for the planet. But why is there still so much of it around and what makes it so hard to recycle?
Greg Foot and Which? researchers investigate the current state of supermarket packaging. We look at why so much of the plastic that wraps our food is completely unrecycleable and whether biodegradable plastic is the answer.
Plus, what can we do about the food that simply has to be wrapped up to protect it from damage that would send it straight to landfill?
