Energy White Paper

My Lords, on hydrogen cars, we are looking at fuel cells and developing the technology on that level. As I mentioned, we will have the Energy Technologies Institute, which will support research in those areas. On vehicle emissions and the efficiency of cars, we are working with the European Union to increase the amount of biofuels used in vehicles from the 5 per cent that we have established under our proposals to the 10 per cent that the EU has outlined. We are saying that it is important that biofuels are developed in a sustainable way and that we have a second generation of biofuels that can be used in vehicles with a greater blending of fuels and all the rest. On agricultural crops, the argument is similar; we must be aware of sustainability when it comes to biofuels and the development of energy crops in this country for co-firing. We need to keep apprised of that. Again on transport, we are developing a low-carbon transport innovation strategy that will consider a number of issues and how we can improve the low-carbon element of our transport in the UK. We also support the Commission’s proposal that aviation should be included in the EU Emissions Trading Scheme, and are looking at surface transport. The noble Earl asked another question that I did not catch.
