Climate change is set to alter our planet and human beings need to change the way we live and work. But how do we know exactly what changes to make? New technology could help us make informed choices - from sensors counting pollinating insects in fields, to power sockets that tell us how green our energy is, to apps that enable communities to discuss change in their local area. These ideas are part of the Tech for Our Planet challenge, which is being run by the UK government as part of the COP26 summit. We check out the three projects and explore how new technology has the potential to change our behaviour. Produced and presented by William Kremer from COP26.

Sixteen percent of greenhouse gas emissions could be saved by using biochar, a simple fertilising technique adopted by tribes in the Amazon thousands of years ago. If produced on an industrial scale, scientists say biochar could be as powerful as renewable energy in the fight against climate change. Picture Credit: Carbofex and Puro.earth

Fake medicines are responsible for hundreds of thousands of deaths worldwide each year. But inventors around the world are coming up with ways to spot the fakes. In Nigeria, pharmacists are using a pocket-sized nanoscanner and mobile app to analyse light shone through a pill, powder or liquid. A Ghanaian entrepreneur has developed a way to verify a barcode or a series of numbers on a box of medicine, using a mobile phone. And in Finland, you can take photos of your medicine and get a detailed analysis of the packaging, pill or powder, to find out if it’s authentic or not.
