SHANGHAI’S greenery authorities issued a guideline on landscape illuminations yesterday to improve energy efficiency and combat light pollution.

The city’s landscape lights are mainly in downtown areas, and mostly located in three belts — along the banks of Huangpu River, between Yan’an Elevated Road and Century Avenue, and along Suzhou Creek. They can also be found on business streets, at key traffic, culture and sports facilities, on arterial roads and at public venues, according to the guideline.

Shanghai is renowned for its landscape lighting and enchanting night scenes.
