A recent study has revealed a surprising connection between the UK government's 'Eat Out to Help Out' scheme and air pollution in London. The initiative, which aimed to boost the hospitality sector by subsidizing restaurant and pub meals, inadvertently contributed to increased air pollution during the summer of 2020, a time when the public was urged to minimize pollution to protect vulnerable individuals. The study, conducted by Dr. Ian Chen from Imperial College London, analyzed data from a research monitoring site in London's Marylebone Road and uncovered unusual air pollution peaks. These peaks occurred during the evenings of Monday to Wednesday, coinciding with the 'Eat Out to Help Out' scheme's operational days. The pollution contained fatty acids from cooking, but its timing and chemical composition suggested it was linked to commercial cooking rather than traffic changes. This finding is significant as commercial cooking has been identified as a source of air pollution in London and Manchester for over a decade, yet it is often overlooked in pollution control measures. The study highlights the need for regulators to treat commercial kitchens as a significant and manageable source of urban air pollution. Interestingly, the pollution pattern persisted even after the scheme ended, suggesting a lasting impact on consumer behavior and air pollution. The study also mentioned the detection of particle pollution from restaurants spreading into residential areas and even from airline catering at Gatwick Airport, underscoring the far-reaching impact of commercial cooking on air quality.
