The Earth Hour is an initiative launched by the World Wildlife Fund (WWF) and is the largest social event globally. So far it has been observed in 7,000 cities and towns across 172 countries and territories globally.

Vietnam first joined the Earth Hour campaign in 2009. In 2022, the country saved 309,000 kWh of electricity, equivalent to VND 576.1 million (more than USD 24,000).

The Earth Hour campaign in Vietnam is hosted by the Ministry of Industry and Trade and receives the support of many businesses, especially Vietnam Electricity (EVN) which serves as the primary sponsor of the campaign.

The campaign is one of several actions being taken by the Vietnamese Government and people, demonstrating their strong commitment to uniting with the world in the fight against climate change.
