On 2 October, E4tech's Luca Bertuccioli will join members of the government, academia, and the private & public sectors at the WTO Public Forum 2013 for a panel discussion on global value chains in green goods and services. The annual event, hosted by the World Trade Organisation, aims to provide a platform for public debate across a wide range of WTO issues and trade topics. Using photovoltaics as an example, Luca will discuss how the dependence on policy incentives to create the market for sustainable energy technologies has meant that these markets have moved around quite rapidly as policy regimes have changed. In addition, these technologies require a specialized local labour force for effective deployment and this downstream part of the value chain has proven challenging to put in place, in particular when driving policies have changed. Given that much of the future deployment of sustainable energy technologies will necessarily happen in developing countries, this underlines the need for significant transfer of skills and know how if climate change mitigation objectives are to be met.
