​​Revealing hidden links between deforestation and energy in Southeast Asia

Within the past two decades, the forest biomass industry — cutting forests to make wood pellets to be burned in power plants — has been booming as countries strive to meet global energy demands. This growth comes despite scientists’ warnings over the industry’s harm to the climate and its contribution to deforestation — increasingly in the tropics.

In 2024, Mongabay reported extensively about this practice, including in Indonesia’s Gorontalo province. There, Mongabay’s Indonesia-based news bureau’s investigative reporting on increased deforestation called attention to the existence of two palm oil companies that after their forest cutting permits were revoked, reapplied under the nation’s energy plantation forest scheme. In mid-August, Mongabay visited the area to ground truth satellite imagery indicating deforestation and documented firsthand the activities of the companies. By September, Mongabay Indonesia released another report (also adapted into English) detailing the opaque activities of the wood pellet processing company in Gorontalo that was sourcing raw materials from both companies.

Mongabay’s findings showed the alleged deforestation as likely violating sustainability principles and that some of the exported wood pellets were not recorded in the Ministry of Environment and Forestry’s system. Furthermore, the processing company’s transshipment activities are suspected to be in marine conservation areas, raising serious questions about the legality of its operations. The wood pellets being produced were destined for burning by biomass energy plants in East Asia, most likely Japan or South Korea. Collectively, the reportage raised alarms about environmental and regulatory violations, and additional international media coverage, including by the Associated Press, shortly followed. The investigation also prompted the company to send a letter of denial.

Impact

Soon after these publications, local authorities and industry groups convened to address the issues, when the Regional Leadership Coordination Forum (Forkopimda) and the Indonesian Biomass Energy Producers Association (APREBI) held a Forum Group Discussion. Indonesia’s Law Enforcement Agency (Balai Gakum) in Sulawesi also reportedly plans to investigate the alleged illegally sourced pellets revealed by Mongabay’s report, and several NGOs, including The Center of Economic and Law Studies (CELIOS), used the report in their research. The reports also sparked discussions in Jakarta hosted by NGOs including Forest Watch Indonesia, Trend Asia, and CELIOS.

The impact extended well beyond Indonesia. In late 2024, South Korea announced a sweeping change to its biomass subsidy policy. Beginning in January 2025, subsidies would no longer be granted for new biomass energy projects or for existing state-owned plants that burn biomass with coal (“co-firing”). In addition, existing government financial support for dedicated biomass plants using imported biomass would be reduced, while support for privately owned co-firing plants would be phased out entirely over the following decade. As a result, forest advocates hailed the biomass reform as a step in the right direction, potentially setting a new, environmentally sound precedent for the region’s forests.

This reform was documented in the report “Plan to Improve the Market Structure of Biomass Fuels and Energy” produced by Korea’s Ministry of Trade, Industry, and Energy, the Korea Forest Service, and its Ministry of Environment.

The lead author of the October 2024 report, “Unheeded Warnings: Forest Biomass Threats to Tropical Forests in Indonesia and Southeast Asia,” prepared by Earth Insight, Auriga Nusantara, Forest Watch Indonesia, Solutions for Our Climate, Trend Asia, and Mighty Earth, said that “Mongabay’s reporting – both English (Annelise Giseburt) and Bahasa – on wood bioenergy development in Indonesia helped to build global pressure at the moment South Korean activists were working with a legislator that resulted in policy to stop wood pellet imports from Indonesia’s forests. It’s always hard to draw a straight line, but I think it’s fair to say Mongabay’s coverage helped to build the crescendo. Annelise was fantastic and the local Bahasa journalists did in-depth investigations at the pellet mill.”

This case illustrates how deeply reported, independent journalism can uncover obscure but critical links between local environmental harm and international policy, ultimately helping to protect threatened forests and support more sustainable energy decision-making.
