Big things that make a small difference. We’re 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.
