On 28 January 2008 the European Commission will launch the second EU Sustainable Energy Week (EUSEW 2008). This is the world's largest open forum on sustainable energy, bringing together stakeholders on a local, regional, national and European level. The programme includes renewable energy sources, energy efficiency, clean transport and alternative fuels. During the week, 80 events in eight countries will be organised by more than 100 key industry and social players. EUSEW 2008 follows the adoption by the Commission of a revised climate change package (see previous article).
