 Well it's estimated that about 200 billion pounds of investments will have to go into the energy sector and that is not just new power stations but the whole energy infrastructure. So that's a huge opportunity for industry to not just invest into a transition into a low carbon economy but more importantly to provide growth which is needed in the current environment. So for end power that's a big opportunity. We have just invested in the last three years three and a half billion pounds into new more efficient plants and indeed into renewables which is about 60% of the total investment we have made. I think for Shell the low carbon transition offers a number of opportunities but I really highlight three. The first one is about gas replacing coal basically that allows for a 50% reduction in emissions compared with coal emissions. The second one is about CCS and carbon capture and storage so that's all about decarbonising the fossil fuel power sector completely and the last one is about biofuels. We still need liquids in transportation and biofuels provides a great opportunity to decarbonise those liquids. So low carbon transition is going to happen. It's not an option it's a will do must do around the world and it will require smart everything smart networks smart energy smart education smart public services it will involve all the technologies all the capabilities to make it smarter. Using ICT in smart everything is going to be a necessity which is for our industry a unique opportunity it is not just the networks it's the applications it's the smartness in doing things different doing things together with the consumers. One of the things that we have to learn better than we did in the past is to include the consumers from day one. They ultimately will decide whether we become a green society or not. We give them the tools they have the choice. I think low carbon transition provides a huge number of opportunities for the chemical industry particularly with the provider of a lot of the building products for the green economy for the new green economy from materials of construction lightweight materials we produce the building blocks for instance for carbon fibre that say the new Boeing Dreamliner is using right the way through to biofuels where we've got huge opportunities in that area as well.
