I am Andreas Kopp, working for the World Bank in Washington. I work for the Sustainable Development Network, in the Department for Energy, Transport and Water. Most of my work is now on transport and climate change, trying to find out ways how transport can be made environment friendly, without sacrificing the role of transport for trade and urbanization. Other areas I am working on are the importance of transport costs for international trade and the regulation of the transport sector. I also teach transport economics at the School of Public Policy at the George Mason University. Much of what I do extends work I did for the OECD in Paris.
