Hello, welcome to the programme. Today, it's consumer power versus climate change. Can shoppers

change the world? Now, we're going to narrow in on one specific question, in fact,

on labelling, because if we think many members of the public will want to use their

buying power to select the most sustainable products,

they'll need to know which products are sustainable.

And that would allow buyers to reward the good producers and avoid the bad.

But to do that, they'll read the label if they can rely on it to give them honest and useful information.

And the key thing is that if labels can be greenwashed,

making things look better than they really are,

market pressure from consumers will not work.

Now we know from nutritional labelling and the debates that's caused,

this can be a fraught issue.

So let us look into the future of carbon and eco-labelling with three guests who have an

array of experience in the field. And first up is Emma Keller, head of sustainability at Nestle.

And Emma, take us through what Nestle's ambitions are for sustainability.

Hi, and good morning. Yes. We've committed to be net zero by 2050 with the goal of halving our emissions by 2030.

And of course, providing more transparency and information to consumers.

We've joined, along with many others, a coalition led by Foundation Earth that have brought

people together to try and understand, well, how do we do this?

How do we get the right data, the right information and put it into a label that's going to be useful for consumers to make those decisions? So at the moment, there aren't widely used labels either that look at just carbon or look across a much broader range of environmental impacts that are available on products. So what we're doing

as part of this coalition is trying to delve into the science to look at a couple of different
