In 2030, cars will be electric, and instead of owning them many drivers will borrow from car clubs or lease them. Airlines will no longer fly short distances, and long-haul trips will be a rare treat. Such is the vision of a zero carbon Britain by 2030, as seen by the Centre for Alternative Technology (Cat).
Cat joins us from Monday to Friday this week on You ask, they answer to discuss its ideas for a greener Britain. Just post your questions on green living, clean energy and sustainability below.
Want to know more about Cat's awareness-raising work or visitor centre in Wales? Got a question about green energy at home, such as how and when to fit solar panels? Or are you interested in its 2030 zero-carbon Britain report and its ideas of turning mango and bananas into a luxury by halving food imports?
Post below, and Cat will do its best to answer.
