MANILA - Malacañang on Saturday urged the public to take part in the commemoration of Earth Hour as it emphasized government's commitment to address climate change.

In a statement, Presidential Spokesperson Harry Roque issued a nationwide call for Filipinos to take part in the annual hour-long observance, where lights are turned off from 8:30 p.m. to 9:30 p.m.

"We encourage the entire Filipino nation to take part in this collective human effort to save our planet from the ill effects of global warming. For one hour this evening, from 8:30 p.m. to 9:30 p.m. local time, let us all switch off our lights in our homes or in our workplaces to symbolize our commitment to saving Mother Earth," Roque said.

"One simple step we make, when taken all together, leads to a big stride for the entire human race. Let us join the entire world as it shines a light upon the importance of climate action by going dark," he said.

He cited how Earth Hour aims to raise awareness on the need for climate action and the promotion of sustainable energy sources.

"Our country has been identified as among the most vulnerable to the impact of climate change. The President has recognized this and has made the protection of the environment a priority during his State of the Nation Address," he said.

Earth Hour events are expected to be held across the country Saturday night, including the main commemoration at the Cultural Center of the Philippines, where it was first held in 1998.
