The observance of Earth Hour, a global event calling attention to the need to tackle global warming by turning off power for an hour, in Vietnam will be centered in the central city of Hue.
A total of the country's 29 cities and provinces will participate this year's campaign to be held on March 26, according to a press release from the Vietnam office of the World Wildlife Fund.
Worldwide, millions are expected to participate in the event.
This year's message is: "Earth Hour, go beyond the hour." In keeping with this theme, the campaign in Vietnam will carry out many other activities for individuals, students, communities and businesses starting this month and continuing for the coming 12 months.
A website dedicated to the campaign will be launched to encourage people to think and take practical action for the environment throughout the year, Tran Minh Hien, Vietnam Country Director of WWF's Greater Mekong Program said in the statement.
Van Mai Huong, runner-up of Vietnam Idol 2010, has been named as the sole ambassador of the campaign, she added.
Vietnam first joined the global initiative in 2009 with the campaign centered in Hanoi. Last year, it was held in Ho Chi Minh City.
Earth Hour began in Sydney three years ago, when two million people switched off their lights.
The event has become the largest voluntary action ever recorded and now involves participants in 128 countries throughout the world.
