Cities can be vibrant, innovative and exciting places to live but unplanned, high-carbon urban growth, alongside rising energy costs and increasing demands on service delivery, are putting pressure on local governments, threatening economic growth, poverty reduction and urban quality of life, and contributing to dangerous rises in global temperatures and subsequent climatic changes. It is understood that cities which pioneer a low emissions development model today will attract future investment, reduce energy costs and become efficient, inclusive, clean places to live and work tomorrow.Local governments have an important role in addressing non-technological barriers to support the transition to a renewable energy future. Two projects will illustrate approaches taken in this context. The Urban-LEDS project (www.urban-leds.org), funded by the European Commission, and implemented by ICLEI and UN-Habitat, supports local governments in emerging economy countries (Brazil, India, Indonesia and South Africa) to integrate low-carbon strategies into all sectors of urban planning and development, by defining and approving Urban Low Emissions Development Strategies (Urban-LEDS). The process is supported by experienced European cities, especially those with an understanding of policies, technologies and stakeholder engagement relevant to energy efficiency, renewable energy electricity, heating and cooling. The second project - The Municipal Climate Action Plan (PACMUN) (http://iclei.org.mx/web/index.php/seccion/PACMUN) – has been successfully implemented in Mexico by ICLEI, and is extended for two more years. Here technical and institutional assistance is offered by the National Institute of Ecology and Climate Change (INECC), with the project is financed by the Embassy of the United Kingdom in Mexico. In both projects the switch to renewable energy is being explored in a wider community strategy.The paper will address the methodology and approach taken by selected cities, with a focus on planning and approach to renewable energy, the use of local resources and the involvement of civil society in processes.
