As Italy prepares for its seasonal time change, the debate over abolishing the practice and adopting permanent Daylight Saving Time (DST) has regained momentum. Proponents, led by the Italian Society of Environmental Medicine (SIMA), are urging the government to make DST year-round, citing substantial economic, environmental, and public health advantages.
A key argument centers on energy conservation. According to analyses by Italian electricity grid operator Terna, an extra hour of daylight in the afternoons significantly reduces electricity consumption for lighting. This translates into hundreds of millions of euros in savings on national energy bills and a considerable reduction in CO2 emissions. A proposal for permanent DST in Italy suggests it could lead to an annual saving of around 720 gigawatt-hours, which would also bolster the country's energy independence.
Beyond the economic case, advocates point to the potential health and environmental benefits of maximizing afternoon sunlight. Studies suggest that permanent DST could lead to improved public mood, reduced incidence of seasonal affective disorders, and more opportunities for outdoor social and physical activities. The semi-annual clock change has also been linked to disruptions in circadian rhythms, impacting sleep patterns and increasing health risks in the days following the switch.
The primary obstacle to Italy's proposal is not domestic but European. A 2000 EU directive currently mandates a coordinated, twice-yearly time change across the bloc to ensure the smooth functioning of the single market. In 2018, the European Commission proposed to scrap this rule after a public consultation showed overwhelming support for the idea. However, progress has since stalled as member states have failed to agree on a unified path forward. There is a significant divide, with northern countries like Finland and Denmark showing different preferences from southern nations, and no consensus has been reached on whether to adopt permanent summer or winter time. Until a coordinated decision is made, Italy and other member states are bound by the current system, leaving the debate on abolishing the seasonal time change in legislative limbo.
