This is a data book of facts and figures about carbon emissions and energy use in the UK. The book emphasises the impact of domestic consumption and personal lifestyle choices. It's not about politics or ethics: there are no grand designs for how the future should look. Instead, it provides the information you need to calculate not only how you can reduce your carbon footprint, but also how you can save money by reducing your energy bills. Tables and charts show average UK consumption and emissions, renewable-energy potential, historical trends and international context. It provides guidance on calculating your own emissions and determining the impact of changes you can make. It will help answer questions such as: how much carbon will I save if I stop eating meat? Should I scrap my old car and buy a new one? How much energy do I use each day making tea? Would it help if we went back to horses and carts instead of vans? My roof faces south-east so is it still worthwhile putting up solar panels?
