A recent study has examined the potential consequences of France abandoning the GMT+1 time zone, recommending sectoral adaptations to mitigate disruptions. The research, conducted by a team of chronobiologists and economists, highlights that a shift to GMT (UTC+0) could affect various sectors differently, including health, energy, and transportation.
According to the study, the health sector may benefit from better alignment with natural daylight, potentially improving sleep patterns and reducing circadian rhythm disorders. However, the energy sector could face increased electricity demand during winter mornings, requiring adjustments in grid management. The transportation sector might need revised schedules to maintain efficiency.
The report emphasizes that any transition should be gradual and accompanied by public awareness campaigns. It also notes that neighboring countries in the European Union would need to coordinate to avoid cross-border complications. As of April 2026, no official decision has been made by the French government regarding a time zone change.
