In his 2006 book Heat, George Monbiot set out a bold and inspiring vision of how Britain could reduce its carbon emissions by 90% by 2030, thereby keeping runaway temperature rises at bay and mitigating the worst effects of climate change. The only problem with Monbiot's tightly argued and highly convincing call to action is that it demands a prompt and sweeping response at government level and beyond, which can seem awfully remote and disempowering to the ordinary individual wondering what he or she can do personally to make a difference.
Cue veteran green campaigner George Marshall to enter the climate change fray with Carbon Detox, an irreverent, humorous and immensely readable guide to getting to grips with this thorny issue on a personal level. Replacing piles of dull statistics with vivid metaphors for understanding climate change - a rollercoaster ride we are about to embark on and cannot climb off - Marshall skilfully conveys the nature and urgency of the problem. He also excels at revealing Humankind's seemingly limitless capacity for denial, drawing an analogy with the tobacco industry-sponsored campaign of the 1950s to expose the phoney contemporary industry of climate change scepticism. And through an incisive analysis of personality types borrowed from the field of marketing, Marshall offers some clever ideas for those seeking to convince sceptical friends, family and colleagues.
But Carbon Detox's ultimate purpose is to serve as a step by step guide to taking positive action on climate change. Having explored the 'plastic bag fetish' - whereby we often unwittingly glorify trivial actions to make it look as if we are doing something positive while missing the bigger picture - Marshall introduces the beautifully simple analogy of weight-watching to show how we can count our 'carbos' - the kilos of CO2 gas we burn each year - and set about cutting our personal carbon emissions to a level that doesn't compromise the lives of others. And where Carbon Detox really hits home is in successfully illustrating that, rather than being a penance, by treading more lightly on the earth we can feel happier, smarter and more in control of our lives - surely a worthwhile goal for all.
