Despite commitments to renewable energy and two decades of international negotiations, global emissions continue to rise. Coal, the most damaging of all fossil fuels, has actually risen from 25 per cent to almost 30 per cent of world energy use. And while European countries have congratulated themselves on reducing emissions, they have increased their carbon imports from China and other developing nations, who continue to expand their coal use. As standards of living increase in developing countries, coal use can only increase as well - and global temperatures along with it. In this hard-hitting book, Dieter Helm looks at how and why we have failed to tackle the issue of global warming and argues for a new, pragmatic rethinking of energy policy - from transitioning from coal to gas and eventually to electrification of transport, to carbon pricing and a focus on new technologies. Lucid, compelling and rigorously researched, this book will have a lasting impact on how we think about climate change.
