Gaia South was the first Filipino consultancy firm to conduct a programmatic Environmental Impact Assessment (EIA) in 1994 for the Philippine National Oil Corporation-Petrochemical Development Corporation (PPDC) Petrochemical Industrial Estate located in the Municipalities of Limay and Mariveles, Province of Bataan. The Environmental Compliance Certificate (ECC) was issued and PPDC thereafter sought the assistance of Gaia South for its environmental and monitoring activities.

The preparation of the Environmental Impact Statement (EIS) Report for the Masbate Gold Operations Project (the reopening of the Atlas Masbate Operations) in Masbate Province, Philippines, with respect to which an ECC was issued in June 1998, is one of the fastest ever for a mining operation. Gaia South has prepared EIS and Environmental Risk Assessment (ERA) reports in critical areas such as Palawan Province, Philippines for two (2) nickel mining projects—Rio Tuba Nickel Mining Corporation in the Municipality of Bataraza (1996) and Long Point Nickel Mining in the Municipality of Quezon (1997)—as well as for a cement plant/limestone quarrying project of Fenway Resources Ltd. (Canada) (1997). Gaia South likewise helped obtain ECCs for two (2) mineral processing plants adjacent to the Rio Tuba Nickel Mining Project—Japanese-owned Coral Bay Nickel Corporation (2001 and 2007) and Malaysian-owned Unichamp Mineral Philippines, Inc. (2012).

Gaia South also conducted the social acceptability and perception surveys, community organizing, and ERA for the Philnico Nickel Mining Project in Nonoc, Surigao del Sur, Philippines. Similarly, Gaia South was a consultant of Climax Arimco Mining Corporation in promoting social acceptability of its Didipio Gold/Copper Project in the Nueva Vizcaya, Philippines (1999); and the social acceptability requirement for TREE, Inc., a tree plantation in Bataan, Philippines.

Following issuance of DENR Memorandum Order No. 2016-01 dated 8 July 2016 directing the audit of all operating mines in the Philippines, Gaia South conducted third party audit for several mining companies, which allowed a set of fresh, non-biased eyes to assess their environmental performance and helped close gaps ahead of government audit.

In 1998, the company conducted an EIA for the proposed 120-km oil pipeline project from Limay, Bataan to Pulilan, Bulacan, Philippines. The company also provided technical assistance to UEM-MARA and the Public Estates Authority to comply with the additional information required by the DENR for the C-5 Link Expressway by formulating a Relocation and Compensation Plan.

Gaia South has done a significant number of power projects including the PNOC Northern Negros Geothermal Exploration and Development Project in Negros Occidental, Philippines (1993); the CEMECO Power Project in Cebu, Philippines (1994); the Sabah Shipyard Naphtha Power Plant Project in Manila, Philippines (1994); the Tiwi Geothermal Project in Albay, Philippines (2001); the Sem-Calaca Coal-fired Power Project in Batangas, Philippines (2011); the DMCI Power Corp. Coal-fired Power Project in Mobo, Masbate (2008 and 2014); and the Montelago Geothermal Exploration Project in Oriental Mindoro, Philippines (2014). In 2015 and 2016, Gaia South was engaged by renewable energy company Alternergy to conduct EIA over its run-of-river power plant projects in the Provinces of Ifugao and Nueva Ecija, Philippines.

Gaia South has been involved in many real estate projects in the Philippines, including the Tagaytay Highlands project of Belle Corporation, as well as the development projects of DMCI Homes, Saratoga Plantation, and G&W Architect, Engineers, Project Development Consultants.

Gaia South has worked with Sinclair Knight Merz (SKM) in implementing the Metro Manila Air Quality Improvement Sector Development Program. This is an Asian Development Bank-funded project aimed at assisting industries, commercial establishments, and public transport companies in making the investments necessary for monitoring and reducing air emissions.

In 2016, Gaia South was engaged to prepare a Resettlement Action Plan for the Japan International Cooperation Agency (JICA)-funded North South Commuter Railway Project connecting Tutuban, Manila and Malolos, Bulacan, Philippines.

history of gaia south

Gaia South was organized on 7 August 1992 by a group of erstwhile officials of the Philippine Department of Environment and Natural Resources (DENR) led by former DENR Secretary Fulgencio S. Factoran, Jr., coming off an immensely successful five-year stint at the helm of the DENR. Under his leadership, the DENR underwent a massive transformation that saw significant policy reforms, highlighted by the Philippine Strategy for Sustainable Development (PSSD), which sought to reverse the decimation of the country’s forests and other natural resources and integrated natural resource utilization with environmental protection.

The principals of Gaia South were involved in the formulation of the PSSD, which was adopted by the Philippine government prior to the United Nations Conference on Environment and Development in 1992. They have spearheaded efforts to establish policy and legislative reforms to strengthen local environmental conservation and sustainable development programs.

Today, Gaia South is at the forefront of efforts to balance economic development with environmental protection and social equity in the Philippines. Gaia South’s reputation for thoroughness and professionalism, and its uncompromising commitment to ecologically sustainable practices have helped the company develop the trust of its clients and government regulators. This has paved the way for its success, as evidenced by consistent government approvals on its clients’ applications for ECC and other government permits and licenses.

Encouraged by its success and driven by its vision, Gaia South now looks at sharing its valuable experience in other developing economies, especially in neighboring Southeast Asia. Certainly, issues on sustainable development transcend national boundaries, and are best addressed through cooperation and concerted efforts among nations.
