I agree entirely with you, Mr Speaker, and observe that it is not only ironic, but totally counterproductive that a Member of Parliament who wished to ask Ministers about carbon is prevented from doing so by protesters purporting to care about carbon. I will do my best to answer my hon. Friend’s question, anticipating what he might have asked. I anticipate that he would have asked me, on behalf of his constituents in Windsor, about Heathrow expansion. He would have expanded on the carbon cost of a third runway, which is what is set out on the Order Paper. Of course, Heathrow expansion is a private sector project, which will need to meet strict criteria on air quality, noise and climate change. He is right to raise those questions. Clearly, the aviation sector has a big part to play in delivering the UK’s net zero commitment. Were he here, I would hope to be able to reassure him that we are continuing, through technology and aviation, to look for ways to reduce the carbon footprint of aviation, to ensure that we can transition to guilt-free flying. We will be setting out the final jet zero strategy early next year, which will show how we can support the benefits of air travel and the opportunities that aviation decarbonisation can bring to the UK. I say to the whole House and to everyone who is concerned about this issue that it is emissions, not flying, that is the problem.
