The measuring and reporting of carbon emissions by companies in the food industry is not uncommon.

It helps businesses understand where their environmental impacts lie, where they need to reduce emissions most, and helps track their progress towards sustainability.

The problem is, they do not all measure their carbon footprint in the same way.  

That leads to inconsistencies and can make it difficult to compare one company’s emissions with another.

But, we have news of progress - among some of the UK’s biggest supermarkets at least.

WWF and the charity WRAP have joined forces to create the Retailer Net Zero Collaboration Action Programme, which aims to remove the barriers posed by a lack of standardised reporting methods.

And eight supermarkets have signed up. Listen to the full episode to find out more.
