The French Environment Ministry has announced that a new law will come into effect in July that requires non-residential buildings to turn off interior and window display lights each night. Under the new legislation lights in shop windows will need to be turned off at 1am and lights in office and other commercial buildings switched off an hour after the last employee leaves. The new law is planned to save around 250,000 tonnes of carbon dioxide emissions each year as well as enough energy to power 750,000 French households. The ministry believes the law will change attitudes and help the country become a pioneer in reducing light pollution and energy use.
