Deborah Meaden and Felicity Hannah are back and this time they're investigating carbon offsetting.
Many businesses use offsets as part of their journey to net zero. So what are they and how do they work? It turns out it's not as simple as planting a tree!
In fact, to show it is about so much more than planting trees, Fliss visits a peat bog.

Deborah and Fliss also discover offsetting is more controversial than many of us realise. Some environmentalists believe it is a vital tool in the fight against climate change. But others say it allows the planet's biggest polluters to carry on business as usual.
And if we do choose to offset, how do we do it properly and how can we be sure these projects really are keeping their promises to take carbon out of the atmosphere?
The pair speak to Maggie Kim, boss of The Gold Standard, one of several organisations which set standards to certify offsetting projects.
