Which? Investigates episode three: Are electric cars really greener?

The new Which? podcast is kicking off with a series helping you to be a more sustainable consumer. Episode three asks whether switching to an electric car really is greener.

Which? Investigates episode three: Are electric cars really greener?

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.

Episode Three: are electric cars really greener?


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?

In this Which? investigation Greg Foot reveals how these ‘zero emission’ cars don’t come with a zero footprint. He asks whether the UK is ready for such a dramatic change to our transport infrastructure, and discusses whether the switch to electric is actually feasible for many of us in the UK.

Episode Two: does your phone come with an expiry date?

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?
