SM Supermalls and SM Cares participated in the Global Lights Switch Off for Earth Hour 2023 last March 25 in support of the annual campaign by the World Wildlife Fund (WWF), with 82 malls and various properties nationwide joining millions in more than 190 countries all over the world to raise awareness about the climate crisis.

This year marks the company's 15th year of continued support for Earth Hour, where mall signages and lighting in key areas were turned off or reduced to 50 percent working capacity. Tenants were enjoined to participate by dimming or turning off signages and select lights within their stores.
