Measures for Earth Hour

17 Mar 2025 / Singapore

The Maritime and Port Authority of Singapore (MPA) is encouraging the maritime community to participate in this year’s Earth Hour from 8:30pm to 9:30pm on 22 March.

In its Port Marine Notice No.22 of 2025, the MPA states that it will support Earth Hour on Saturday 22 Mar 2025, from 8:30pm to 9:30pm by switching off non-essential lightings in our facilities and MPA’s operated vessels. The navigational lanterns at the lighthouses will remain operational during this period while non-essential lightings will be switched off.

For vessels:
Masters and crews of vessels at anchor in port are encouraged to observe Earth Hour by switching off non-essential lights of these vessels while ensuring compliance with the provisions of the Convention on the International Regulations for Preventing Collisions at Sea, 1972 (COLREGS) and the applicable Safe Management Systems under the International Safety Management (ISM) Code.

For port terminals:
At operational areas in PSA’s and Jurong Port’s terminals, only essential lightings should be maintained to allow for safe operations.

For passenger terminals:
Passenger terminals that are not providing ferry and cruise services during Earth Hour should switch off all non-essential lightings from 8.30pm to 9.30pm.
