Global Cleantech 100 In association with the Carbon 09.09.09 Society Guardian The top 100 companies in clean technology | guardian.co.uk/globalcleantech100 Trust and the Cleantech Group As we enter a new era of innovation driven by the emerging low-carbon economy, we must ensure bright ideas get the funding they need Lord Mandelson, page 5 Introduction Worldwide concern This is the launch of the ﬁrst global Cleantech 100. The panel of experts believe these companies have ground-breaking low-carbon technologies to make them among the world’s most promising contenders to propel the planet to a greener, safer place. This list provides a showcase for these companies with a web address to ﬁnd out more. For those without millions of pounds to invest, it is a chance to see how green slime, silicon, new batteries, sunshine and human ingenuity can be put together in any number of combinations in an eﬀort to save civilisation. The list has been compiled by the Cleantech Group, a provider of global research, events and advisory services on cleantech innovation, in collaboration with the Guardian. It names 100 companies; not in order of merit but grouped alphabetically into solar, wind, water and waste water etc. There are many companies competing in some sections and only a few in others. All are worth having a look at – if only to cheer yourself up about the prospects for the future. There are also articles by the business secretary, Lord Mandelson, who talks about Britain’s plans for cleantech; Tony Juniper, a Cambridge academic, who exorts governments to do even more and grab the opportunity these technologies have to oﬀer; and interviews with investors, cheerful about the prospects of more than doubling Power for 1,000 homes: a section of the SeaGen tidal system, developed by Marine Current Turbines and now in operation in Strangford Narrows, Northern Ireland their money. Lastly, there is the experience The cream of low-carbon ideas of a company that appeared in last year’s European Cleantech 100, the ﬁrst attempt to boost this sector by selecting promising companies and their products. CamSemi has prospered and – along with 36 other European companies – made it into With the Copenhagen climate summit a mere three months away, innovative and viable the ﬁrst global 100. Its success story solutions in cleantech are in the spotlight. Here are 100 companies to watch, says Paul Brown appears on page 8.

Tony Juniper Comment O n 15 July, the same day the government set out its ambitious plans for climate-changing emissions reductions, TV broadcasts featured the imminent closure of one of the UK’s few wind-turbine manufacturing facilities. Owned by Denmark-based Vestas, the closure of the Isle of Wight turbine blade plant was a tragic blow to the ﬁrm’s 625 employees. It was also symbolic of the setbacks that have for years dogged the development of cleantech ﬁrms in the UK. Even oil majors with vast research and development budgets have scaled back their modest commitments to clean energy. BP has gone from “beyond petroleum” back to oil, and Shell has gone in the same direction. Its decision to withdraw from the £2bn Thames Array oﬀshore wind farm (the world’s largest) marked a massive downscaling in that company’s green ambitions. Meanwhile, both BP and Shell have invested billions in the environmentally disastrous tar sands developments in Canada. So what is going wrong?
