Enormous swathes of pristine forest are being cut down across Indonesia to supply the rapidly rising international demand for biomass material seen as critical to many countries’ transitions to cleaner forms of energy. Nearly all of the biomass from forests destroyed for wood pellet production since 2021 has been shipped to South Korea and Japan, The Associated Press found in an examination of satellite images, company records and Indonesian export data. Both countries have provided millions of dollars to support the development of biomass production and use in Indonesia. Indonesia’s state-run utility also has plans to dramatically increase the amount of biomass it burns to make electricity.
