My hon. Friend is right. She speaks passionately on behalf of her constituents in Twickenham, who I know are blighted by these issues just as much as my constituents in Richmond Park. She is right about the health impacts of long-term exposure to nocturnal aircraft noise, which is strongly linked to sleep disorders and broader health impacts. For each additional 10 dB of night-time aircraft noise that communities are exposed to, there is an increase of between 14% and 69% in residents’ risk of high blood pressure, increasing the risk of strokes and heart attacks. Other researchers have found links between long-term exposure to aircraft noise and an increased risk of obesity, depression and cardiovascular issues. The human cost of these flights is substantial, but when I have raised this issue in the House, Ministers have fallen back on a study by York Aviation that argued that night flights add billions to our economy. That study has been repeatedly challenged on both its outcomes and methodology, and I urge the Minister to instruct his officials to examine the wider body of evidence. Researchers at the transport research service and consultancy CE Delft found that a ban on night flights would harm the national economy only if the passengers who currently arrive on scheduled flights before 6 am were not transferred to other flights. In addition, the Heathrow Association for the Control of Aircraft Noise has pointed out that estimates of the value of night flights often massage definitions of night-time jobs, which inflate key figures. In the light of that, I urge the Government to commit to commissioning a full independent analysis on the impact of night flights on our economy, residents’ physical health and local people’s mental wellbeing, to inform a potential ban on night flights at Heathrow. While night flights are a constant concern to my residents, the spectre of the third runway continues to hang over south-west London. Hansard shows that the third runway has been mentioned no fewer than 115 times in this House, and has been the topic of three debates, two early-day motions and countless open letters. Despite the efforts of dozens of MPs, the last Government resolutely refused to abandon the project. They said that we should ignore the 210 million tonnes of carbon dioxide that it would generate every year, the £100 billion it would cost to clean up the damage that the runway would do to our environment, and the impact it would have on air quality in our communities.
