From farming seaweed to steel production without the fossil fuels, Tom Heap views the fundamental problem of our age from a fresh perspective. Small things that make a big difference. Big things that make a small difference. We鈥檙e going to need every one of them.

In the third batch of programmes he meet the experts behind a selection of fascinating carbon-cutting ideas; the Canadian who can produce a plate of scallops whilst absorbing the ocean's carbon dioxide, the Swedes who can make steel without fossil fuels and the central American fridge detectives who hunt down illegal planet-destroying chemicals.

Dr Tamsin Edwards, with help from the experts at the Royal Geographical Society, runs her slide-rule over the ideas to help Tom assess which are the biggest ideas with the most potential to push back on climate change.
