ver the next 40 years the world economy,which today remains highly dependent onfossil fuels, will need to have kicked itscoal, oil and gas addiction. This willrequire a Clean Revolution, not just comparable, butarguably greater than any previous phase of humanity'sindustrial development over the last 250 years. Privateand public sector co-operation will be vital to makingthat happen.But what exactly does this mean in practice? How dowe shift current patterns of investment andconsumption from existing high-carbon enterprises tolow ones? How do we deploy the necessary technologyso that our energy generation, transportation andindustrial sectors are transformed to sustainable andprosperous models in the future?In some ways, we will only have the final answers tothese questions when the process is complete. Whileorganisations such as the International Energy Agency(IEA) have provided us with the basic roadmaps andunderstanding of what is required, much of thepractical, on-the-ground detail will be discovered alongthe way through a process of learning-by-doing. This underlines why action needs to begin now. Delay not only increases the risk of more damagingclimatic impacts in the future, it also entails greatereconomic costs. The decisions made today will have a major impact onthe infrastructure and energy mix of the comingdecades. Get decisions wrong by starting down thelearning-curve too late, and governments andbusinesses will be left with high-carbon assets that areobsolete in an increasingly low-carbon world. A learning-by-doing approach, which brings togetherbusinesses and governments to solve practicalproblems, forms the basis of The Climate Group's ownprogramme of work. We know that the private sectorwill be critical to providing much of the finance andtechnology necessary for the Clean Revolution. Butbusiness also needs the right policy signals andinvestment frameworks from governments to do this.This should not be a case of governments pickingwinners, but rather establishing the environment thatensures there are enough winners for the market topick from.To this end, The Climate Group is helping to facilitateand catalyse a range of low-carbon, markettransformation pilot projects. These bring togethergovernments, financiers, technology providers, andbusiness end-users to build the trust and confidencefor scaling up a number of low carbon technologiesaround the world.Our LightSavers programme, for example, involves 12major international cities, including London, Mumbai,Tianjin and New York. In each of these, The ClimateGroup is working with municipal authorities to runtrials of different LED (light emitting diode) streetlighting products from a range of manufacturers. Outdoor LED applications have the potential to cutenergy use by as much as 70 per cent over currenttechnology, and have an operational lifetime of up to25 years. These benefits translate into significantfinancial savings for city governments and theircitizens, savings that are already being recognised by the municipalities in question, albeit so far on asmall scale. The objective of these trials is not only to find whichproducts work best under differing conditions, but alsoDELIVERING THE CLEAN REVOLUTION060GLOBAL VOICESOMARK KENBER, CEO, THE CLIMATE GROUPPhoto: © European Union, 2011" "THE DECISIONSMADE TODAY WILLHAVE A MAJOR IMPACT ON THE INFRASTRUCTUREAND ENERGY MIXOF THE COMINGDECADES?
