Hanoi, Da Nang and Ho Chi Minh City will launch various activities on Sunday as warm-ups for the annual environmental event Earth Hour, set to be organized on March 28 around the world.
Lights will be turned off for one hour in the capital city, starting at 8:30 p.m., news website VnExpress reported.
Many other activities will also be held in Hanoi, including the one in which about 1,000 people will ride bicycles around parks and other public places to pick up trash.
Meanwhile, some 1,000 people will play music at the same time to call on the public to save power in HCMC, according to the report.
The lights-off event will then be observed in other cities and provinces across the country on the main day, it said.
Vietnam first joined Earth Hour two years after it began in Sydney in 2007.
The initiative, which is aimed to raise public awareness about climate change, has so far engaged more than 162 countries and territories.
