patches of a once enormous ancient woodland. today, a reforestation project is under way. many countries have committed to planting more trees to soak up c02 but my guide gwyn says the mix of trees planted is crucial to success. when there is a mixed amount of tree species within a forest, so the more biodiverse we have in terms of what s above the ground, the more biodiverse is below the ground and the more carbon ends up in the soil, where it is stored for a very, very long time. so does he think nature alone could lead us to carbon neutrality? this is a recent plantation. there s around about 15 20 different shrub and tree species and this was planted last year, in the last winter, which is a year ago for us now but, as you can see,
steam is then used to wash out the c02 which is processed and stored, ready for local use. this can then start its work over again. three commercial trials are already under way, but this solution is relatively small beer. perhaps one of the best technologies at solving the carbon problem is nature itself. i ve come to brynau wood in south wales, one the last patches of a once enormous ancient woodland. today, a reforestation project is under way. many countries have committed to planting more trees to soak up c02 but my guide gwyn says the mix of trees planted is crucial to success. when there is a mixed

they are purified air so air without c02 or with very little c02 leaves the box. when the filter s full, we close the door and start heating. we heat up the collector up to 100 degrees, c02 is released and we take it out. once the filters are cleaned, the carbon capture can start all over again. perhaps one of the best technologies at solving the carbon problem is nature itself. i ve come to brynau wood in south wales, one the last patches of a once enormous ancient woodland. today, a reforestation project is under way. many countries have committed to planting more trees to soak up c02 but my guide gwyn says the mix of trees planted is crucial to success. when there is a mixed amount of tree species within a forest, so the more biodiverse we have in terms
meaning a high proportion of the c02 touches the surface and is absorbed. steam is then used to wash out the c02 which is processed and stored, ready for local use. this can then start its work over again. three commercial trials are already under way, but this solution is relatively small beer. perhaps one of the best technologies at solving the carbon problem is nature itself. i ve come to brynau wood in south wales, one the last patches of a once enormous ancient woodland. today, a reforestation project is under way. many countries have committed to planting more trees to soak up c02 but my guide gwyn says the mix of trees planted is crucial to success. when there is a mixed amount of tree species within a forest, so the more biodiverse we have in terms of what s above the ground,
