Malacañang on Saturday encouraged Filipinos to "switch off the lights" and take part in the annual Earth Hour to show the country's "commitment to fight climate change."
"Switch off the lights for an hour at exactly 8:30 p.m. and show to the world that the Philippines is an Earth Hour country," presidential spokesperson Ernesto Abella said in a statement.
Earth Hour is an opportunity to stand along other countries in pursuing economic development programs as they aspire for "sustainable, climate change-resilient living," Abella said.
This year marks the 10th anniversary of Earth Hour, which aims to raise awareness on global warming.
Since it was first held in 2007, in Sydney alone, great strides have been made in highlighting the dire state of the planet, according to the conservation group WWF, which organises the event.
