One Meralco Foundation, Meralco's corporate social responsibility arm, partnered with water concessionaire Maynilad Water Services Inc. to reinforce and strengthen reforestation initiatives for the Angat-Ipo watershed, a primary source of raw water in Manila.

Through its environmental sustainability program One For Trees, OMF provided a grant to support the reforestation of the watershed home to some 10,000 native trees. This initiative also involves nurturing and maintaining the 25-hectare area in the watershed.

OMF has been implementing the One for Trees program since 2019 as part of its efforts to emphasize the need for multi-dimensional sustainable solutions for the reforestation and protection of forests in the Philippines by enabling economic and social development for people and communities.

The program, through the help of OMF's community partners, now covers 2.1 million trees in San Miguel and Norzagaray, Bulacan; Siniloan, Laguna; Kalibo and Ibajay, Aklan; Province of Bohol; Butuan; Agusan del Norte; and Pangantucan, Bukidnon. It also covers Meralco PowerGen's reforestation programs in power plant areas in Cebu and Iloilo.
