Whether describing Paris's Journee sans Voiture or electric buses in Beijing and Milton Keynes, Clearing the Air not only suggests that tackling pollution is possible, but also shows how, in many places, the work is already being done. In a news cycle that increasingly informs us that all hope is lost, it is uplifting to read that Smedley, an award-winning sustainability journalist, does not think so.

Clearing the Air is incredibly well researched with plenty of numbers and facts to back up Smedley's arguments. This is an important book and one that I whole-heartedly recommend. Even if politicians are slow to take measures about the air quality where you live, Clearing the Air will help you to play your part in creating a cleaner and healthier future.

Tim Smedley's indignation about the years of cover-ups and lies by governments and corporations is well founded. There are scientific details packed between the covers of this personal account – atmospheric chemistry, automative engineering, health effects and much more. The technical details are woven seamlessly into the story. It left me with a growing feeling of hope: people around the world are demanding breathable air!

Mary Nichols, Chair of the California Air Resources Board (CARB)

A wonderfully written book that takes you through the fascinating and terrifying story of air pollution, and explains how billions of people unwittingly ended up breathing toxic air. What Tim does so well is to articulate a simple truth that ultimately leaves you with hope: it doesn't have to be this way. Air pollution is a man-made problem and Clearing the Air sets out the simple steps that governments and individuals must take to ensure that everyone can breathe clean air. Read it and take action!
