Nguyen Van Phuoc, its deputy director, said the department is planning to switch off street lights, decorative lights and advertising lights at major points in District 1, hold an exchange with the Earth Hour goodwill ambassador of Vietnam, and screen films about this event.
This year the campaign is expected to attract more than one billion people in 1,000 cities around the world. Communities, businesses, and governments have been exhorted to switch off all lights to show they care for the planet.
Earth Hour seeks to heighten awareness about climate change and inspire consumers and businesses to take practical action to reduce their own carbon footprints.
