MANILA, Philippines — Opposition to the United States-led Pax Silica initiative is gaining momentum in the Philippines, with a coalition representing at least 70 organizations calling for a reassessment of the proposed Economic Security Zone (ESZ) in New Clark City, Capas, Tarlac.
The Network Opposed to Pax Silica (NO to Pax Silica) was formally launched on Aug. 31 in Quezon City, bringing together Aeta and farming communities, environmental advocates, scientists, faith-based groups, students, youth organizations, peace advocates and other sectors.
The coalition says the proposed development raises serious questions over ancestral land, agriculture, water, electricity, environmental safeguards, transparency and national sovereignty.
The Manila Times reported that around 200 individuals representing at least 70 organizations participated in the coalition’s launch. Earlier reporting by the Philippine Daily Inquirer said more than 50 organizations had initially signed on, indicating that the opposition network has continued to expand.
Why Pax Silica is facing scrutiny
The Philippines joined the Pax Silica initiative in April 2026 as part of a U.S.-led effort aimed at strengthening supply chains for semiconductors, artificial intelligence, critical minerals and advanced manufacturing. Manila and Washington subsequently outlined plans for a roughly 4,000-acre industrial zone within the Luzon Economic Corridor in New Clark City.
The Philippine government has promoted the initiative as a potential major investment and industrialization opportunity.
The Bases Conversion and Development Authority (BCDA) has said the proposed development could attract between $40 billion and $70 billion in investments when fully developed and generate more than 130,000 high-quality jobs.
But critics argue that the promised economic gains must be weighed against the project’s potential environmental and social costs.
Water and power become major flashpoints
One of the biggest concerns is the amount of water and electricity that a large-scale technology and advanced-manufacturing hub could require.
The BCDA has previously estimated that facilities at the proposed site could eventually require around 65 million to 90 million liters of water per day. The agency has said it is examining surface-water harvesting, recycling and potentially desalination rather than relying on groundwater intended for residential and agricultural use.
Electricity requirements have also attracted attention.
BCDA President and CEO Joshua Bingcang previously said the hub could require as much as 3 gigawatts at full development, while the agency has said the project would seek dedicated power sources and would prioritize renewable energy.
For environmental groups, however, those figures raise a fundamental question: Can Central Luzon accommodate the project’s resource requirements without putting additional pressure on communities, farmers and other electricity and water consumers?
Environmental assessment has not yet been completed
The debate intensified after the Department of Environment and Natural Resources (DENR) said in August that no environmental impact assessment (EIA) application for the specific Pax Silica project had yet been processed.
DENR Secretary Juan Miguel Cuna told a House hearing that the agency also did not yet have a sufficiently clear project description or identified locators for the proposed hub at that stage.
The DENR explained that the existing environmental compliance coverage for New Clark City’s broader master plan does not automatically constitute an EIA for a specific Pax Silica development. A more detailed assessment would be required once specific projects and facilities are identified.
That distinction is important: the absence of a completed EIA does not mean the project has been declared environmentally harmful. It means the detailed environmental assessment for the specific development had not yet been completed.
Farmers and Indigenous communities at the center of the debate
Land rights have emerged as another major issue.
Aeta representatives from Capas have expressed fears that development could affect ancestral territories, livelihoods and community sites.
The government, however, has maintained that affected communities must receive appropriate safeguards and assistance.
In the latest development, the BCDA said it has begun validating the socioeconomic profile of families and Indigenous Peoples in and around Sitio Sapang Kawayan, an area within or near the proposed 1,619-hectare hub.
The census is being conducted with the National Commission on Indigenous Peoples (NCIP) as authorities work to determine the communities that could potentially be affected.
Meanwhile, the Department of Agrarian Reform said it had not received any application for land conversion connected to the Pax Silica hub as of Sept. 3.
DAR also said it would protect agrarian reform beneficiaries if their land were eventually affected by an expropriation process.
These developments suggest that the land and displacement questions remain unresolved rather than settled.
Government says Pax Silica remains an economic opportunity
Despite the criticism, economic officials continue to argue that Pax Silica could help the Philippines move beyond its traditional role as an exporter of raw materials and low-value goods.
The Department of Economy, Planning and Development has said the initiative could help diversify the Philippine economy by attracting investment in industrialization, advanced manufacturing and other higher-value activities.
Government officials have also stressed that investors will still be required to comply with Philippine laws and regulations.
The BCDA has rejected claims that the project would automatically result in massive displacement or uncontrolled environmental damage, saying the proposed site is located within designated buildable areas under New Clark City’s master development plan.
Senate and Congress demand greater transparency
The controversy has already reached both chambers of Congress.
Senate hearings have examined the project’s potential effects on water, electricity, land, Indigenous communities and environmental protection, with senators calling for greater transparency before major commitments are made.
The debate has also exposed uncertainty over exactly what facilities will ultimately be built.
Questions have been raised about whether large-scale data centers, semiconductor facilities, mineral-processing operations or other advanced-manufacturing activities will form part of the final development.
The government’s current position is that the project remains under development and that specific locators and facilities have not yet been fully established.
That distinction matters because the environmental footprint of a semiconductor plant, mineral-processing facility and hyperscale data center can be substantially different.
The bigger question: Development for whom?
For supporters, Pax Silica could give the Philippines an opportunity to attract billions of dollars, create highly skilled jobs and become a more important player in strategic technology supply chains.
For opponents, the project raises a different question: Who ultimately controls the land, resources, technology and economic benefits generated by the development?
The Network Opposed to Pax Silica says it plans to bring its campaign directly to affected communities in Capas and conduct public forums in schools, churches and communities.
The coalition is demanding greater transparency and a reassessment of the proposed Economic Security Zone before the project advances further.
The government, meanwhile, faces the challenge of proving that the promised economic benefits can coexist with environmental protection, Indigenous rights, food security and adequate water and power supplies.
For now, Pax Silica remains a proposal rather than a completed industrial project—and the fight over what it could mean for the Philippines is only beginning.
