and business leaders must tackle environmental andeconomic challenges together to cut emissions, createnew jobs and build a prosperous, clean, green economy.Since 2003, The Climate Group has been one of theworld's most powerful international coalitions ofbusiness and government leaders committed toadvancing the low-carbon policies and technologiesnecessary to make deep cuts in global emissions.Most recently, he led a joint initiative with former UKPrime Minister Tony Blair to accelerate politicalmomentum required for international agreement on aglobal climate deal. He is a member of Vantage PointVenture Partners Advisory Board, a member of theWorld Economic Forum's Global Agenda Council onClimate Change, a judge of the Virgin Earth Challengeand an Advisor to the Planetary Skin Institute. Beforefounding The Climate Group, he spent 15 yearsworking with major corporations, NGOs and UNbodies on the environment. He has been recognisedby Time Magazine and Scientific American for hisleadership on climate change and was an Ernst andYoung 2009 Entrepreneur of the year.INNOVATION TECHNOLOGY059© European Union, 2010look to the smart cities, regions and corporates engaged inthese projects for inspiration on ambitious climate action.These governments and businesses are creating themarket-transformation needed to end our dependence onunsustainable, carbon-intensive energy. There is still atremendous amount to be done. But these climatechampions are helping to deliver the clean revolution anda better, more prosperous world for future generations. nThe Climate Group will host the 5th annual ClimateLeaders Summit at COP16 in Cancún. The summit is aforum for the exchange of practical policy advice betweenstate and regional government leaders, as well as CEOs ofsome of the world's leading low carbon technologycompanies, financial institutions, and corporates.ABOUT THE AUTHORDr Steve Howard is the Founder and CEO of aninternational NGO The Climate Group. He is a leadingauthority on climate change and believes politicians

rban environments carry environmentalimpact, contributing heavily to theconsumption and cost of energy, while at the same time disturbing the balance of nature through artificial light, pollution andwaste. A climate change agenda has become both apolitical and an economic imperative for the world'sleading economies.URBANISATIONLess than a century ago, fewer than 10 per cent of theworld's population lived in cities. Today, that figurestands at over 50 per cent, and by the middle of the21st century it is estimated that three-quarters of us willlive in cities. By 2030, nearly five billion people will beliving in cities, as some 60 million people - equivalentto the population of Great Britain - move into urbanareas every year. Many of these new city dwellers can befound in the emerging markets, where conurbations of20 million inhabitants or more are rapidly expanding. At the same time, cities in developed regions likeEurope and North America must adapt as they becomepopulation hubs for service economies and the post-industrial age changes the very nature of city life.Faced with this unparalleled expansion, municipalauthorities worldwide are now recognising the need tocreate cities and towns that are safe and enjoyable tolive in, to work and do business in, and relax in. As justone example, crime rates are rising in urban areas, andclose to one billion people - almost a third of all citydwellers - live in slum conditions. Quality of life (urbansafety, security, health and well-being), the promotionof commerce, entrepreneurism and tourism, andhistoric preservation are all high on national agendas. Regardless of region and social structure, all citiesshare commonalities: all wish to establish identity, asignature that defines their appeal and theirdifferentiation from other cities in the world, theirregion, or even their nation. This is not only about civicpride, but also an effort to ensure that they remainviable and competitive in the global marketplace. ENVIRONMENTAL AWARENESS Cities are front and centre in the climate changedebate. They account for 75 per cent of the world'senergy consumption and greenhouse gas emissions. Totackle this impact, governments increasingly applylegislative measures to reign in carbon emissions andmeet internationally-agreed targets, while at the sametime they commit significant investment towardsinfrastructure projects that stimulate growth and drivea sustainable global economy.To retain both private and corporate citizens, citiesmust maintain safety and security, either throughtackling and preventing criminal activity, or byproviding safer streets for both motorists andpedestrians alike. Poorly, or inappropriately, installedlighting can decrease safety. At the same light level,more than 80 per cent of people feel safer with bright,white light than with poor quality yellow light.Furthermore, there are financial benefits to well-designed lighting. Cities can recognise financialsavings by reducing crime while they recoup theinvestment costs of improving street lighting betweentwo-and-a-half and ten times after just one year. Wecannot, however, escape the fact that artificial light isan essential part of lighting urban environments, notonly after dark, but also as part of a city or town'sidentity. But it does come with an environmental price.Lighting accounts for 19 per cent of all electricityRight: Harry Verhaar,Senior Director Energy & Climate Change,Philips Lighting B.V.SIMPLY ENHANCING LIFE WITH LIGHT IN THE TRANSITION TOWARDS LIVABLE CITIESINNOVATION 060TECHNOLOGYHARRY VERHAAR, SENIOR DIRECTOR ENERGY & CLIMATE CHANGE, PHILIPS LIGHTING B.V.U
