The noble Baroness asks a simple question which will get a complicated answer in response. A number of changes must take place in greening and reducing our emissions, not least within our domestic environment. We need to move away from the gas in our homes and the hydrocarbons in our cars, and we need to do that in the short term. We need a new strategy which will address the culture. This is not just about what government can do; it has to be about what individual households can do, recognising the cost of each change. We have a strategy, which is available on our website.
