Rooting for the future
Half a million. That isn’t about selling the cars rolling out of its Santa Rosa, Laguna assembly plant.
It’s all about the over 500,000 trees Toyota Motor Philippines (TMP) has planted, nurtured, and continuously cared for across the country, alongside local partners and peoples’ organizations.
Any way one counts it, this represents a huge environmental milestone for even a manufacturing giant like TMP, whose All Toyota Green Wave Project is pushing this endeavor forward. And what better environment to achieve this than in the country’s longest mountain range, the Sierra Madre.
Picture this. If you line up all these 500,000 trees planted in a single file, taking into account the space they require once they’re all fully grown (for example, a narra tree, which is part of what the Project plants, requires up to 3 meters of space for its canopy and roots to grow properly), then these trees would run the entire 500-km length of the Sierra Madre three times over, or the entire length of the Philippine archipelago, from Aparri to Jolo.
What’s even more amazing is that the Project is still only halfway done.
The milestone, which accounts for trees planted by the entire nationwide TMP network, was confirmed by TMP forester Michelle Castejon during the June 26, 2026 graduation ceremony of TMP’s 50-hectare National Greening Program (NGP)-adopted site in Siniloan, Laguna. The NGP, led by the Department of Environment and Natural Resources (DENR), is the country’s largest restoration program that aims to alleviate poverty. Nestled within the Sierra Madre mountain range, this TMP adopted site represents a critical piece of TMP’s commitment to plant 1 million trees by 2030—an overarching goal that consolidates the efforts of TMP, its suppliers, and its entire dealer network.
More than leading vehicle sales and production, where the global automotive giant perennially secures half of the Philippine market share, this reforestation effort marks a legacy achievement. Planting native and fruit-bearing trees on the tail-end of the Sierra Madre and nurturing them to maturity offsets carbon emissions. Volunteers actively protect a megadiverse ecosystem vital for typhoon protection and local livelihoods, making it a tangible way the automotive leader is driving progress toward an eco-friendly future.
Through strategic partnerships with the DENR and local people’s organizations (POs), Toyota has successfully adopted and reforested upland sites like the one in Siniloan.
TMP president Masando Hashimoto, who spearheaded the activity, noted that the event couldn’t have been better timed, aligning perfectly with the Philippine Arbor Day observance on June 25. The 2026 celebration sparked nationwide tree-planting and environmental initiatives. On June 25, a day ahead of Hashimoto and his team in Siniloan, other groups across the network observed National Arbor Day, including the team from Toyota Butuan City, who planted trees at Barangay Baan Km3.
Mark Marcelo, TMP environment engineer, recalled that the Toyota team began looking for a single strategic location in the Laguna area five years ago.
“This location was recommended by the Cenro (Community Environment and Natural Resources Office). We considered both accessibility and biodiversity, because being part of the Sierra Madre mountain range made this area ideal,” Marcelo said. “Crucially, there are local POs in the area to help us. If there are no community groups on the ground after we plant, nobody maintains the area, and the survival rate drops significantly. So those were the vital elements: Accessibility, community partnership, and support from the DENR, which handles the validation and audits the success of the tree-planting operations.”
In a separate announcement, the DENR issued a statement highlighting the long-term survival of the more than 4.2 million saplings distributed nationwide during the Philippine Arbor Day campaign. Environment Secretary Juan Miguel Cuna emphasized: “The true measure of Arbor Day goes beyond how many trees we plant today, but how many continue to grow years from now. A sapling survives only when people care for it. A forest thrives only when communities protect it.”
POs at the core
Marissa Cepeda, a representative of the PO of Siniloan assisting Toyota, underscored this sentiment: “As a PO, we have a major role in the growth of these trees. Alongside government programs, we take care of the saplings, the plants, and the entire forest. This also helps our local farmers by providing sustainable livelihoods.”
She added: “If there were no PO and no Toyota to adopt the area, these trees might not have reached maturity. There is a real possibility that parts of the forest here would have been left unmaintained.”
Castejon added that including the 5,500 trees planted by the team on June 26, the total number of trees sowed, nurtured, and grown at the adopted site over the five-year span has reached 36,000.
“We have completed the five-year adoption program in partnership with the DENR through the NGP. This year marks our official graduation ceremony here in Siniloan, Laguna.”
Carlo J. Tagle, representing the NGP of Cenro Santa Cruz, noted that the collaboration strengthens the bond between the private sector, the government, and most importantly, the locals.
“The end goal is long-term sustainability, even without constant government surveillance,” Tagle explained. “Even when we aren’t monitoring, the locals are there and know exactly what to do because of the capacity-building built into this project. When these trees grow large, they offer shelter for wildlife against the summer heat. During La Niña, when heavy rains and floods are common, they help absorb groundwater and stabilize the mountain soil.”
The last bastion for endangered species
The 50-hectare area adopted by Toyota sits beside the University of the Philippines Los Baños Land Grant Management Office (UPLB LGMO), which covers more than 5,000 hectares. Protecting biodiversity and accelerating reforestation remain two of the most urgent priorities for the Sierra Madre. The UPLB LGMO previously released a statement from its former manager, Dr. Virgilio Villancio, noting that “the majority of the remaining forest cover of the Sierra Madre is in the Laguna-Quezon Land Grant, making it the last bastion for many species that have become endangered in other parts of the Philippines.”
Our group spoke with UPLB Land Grant Management Office Director Reynaldo Lorida, who detailed why protecting this natural barrier is our ultimate line of defense against climate devastation—and why sustainable, multi-year rehabilitation is a necessary legacy.
Shield against typhoons
“The Sierra Madre is the backbone of Luzon, running parallel to the island, and it is our primary barrier against strong typhoons originating from the Pacific,” Lorida stated.
He added: “Its positioning is immensely critical. Studies show that nearly 50 percent of a typhoon’s energy is dissipated once it hits the Sierra Madre range. That means the storms we feel inland have already been weakened by half. Without the Sierra Madre, typhoons would cause unimaginable devastation, particularly across Central Luzon. There is virtually no other natural land barrier there, save for Mount Arayat. Historically speaking, urbanization in Luzon wouldn’t have flourished without the vital cover provided by the Sierra Madre. If this terrain were entirely flat, it is highly possible the region would have turned into a desert.”
My own journey tracking these efforts dates back to the mid-2000s, when I first participated in Toyota’s tree-planting initiatives. I vividly recall joining Toyota Motor Corp’s (TMC) planting and growing activities in Peñablanca, Cagayan Province. Launched in September 2007 as a joint project with the DENR, the Peñablanca Municipal Government, and Conservation International (CI), the initiative aimed to reforest 1,772 hectares of land over a three-year period.
TMC injected reforestation expertise and specialized planting techniques developed through its environmental projects in China and other regions. The goal was to create a self-sustaining ecosystem in the Philippines, where deforestation remains a critical issue, by combining local livelihood support with environmental rehabilitation. By establishing forests dedicated to fuelwood harvesting and encouraging residents to cultivate cash crops like mango and cocoa, the project was seen to address slash-and-burn agriculture and illegal logging, tackling the root causes of deforestation head-on.
