A recent study from Imperial College London has found that the UK government's 'eat out to help out' scheme, which aimed to support the hospitality sector during the pandemic, also contributed to increased air pollution in London. The analysis revealed unusual peaks in air pollution that coincided with the scheme's operation in August 2020. Researchers noted that the pollution was linked to commercial cooking, with emissions peaking on evenings when the scheme was active. This pattern continued even after the scheme ended, suggesting a lasting impact on consumer behavior. The study emphasizes the need for regulators to address commercial kitchens as a significant source of urban air pollution, which has often been overlooked despite its known contribution to particle pollution.
