Indonesia's anti-graft agency says government agencies have agreed on a plan to combat corruption in the forestry industry that costs the state billions of dollars in lost revenue and is behind fires that pollute Southeast Asia's air.

The attempt to address a longstanding crisis in the management and conservation of Indonesia's prized tropical forests comes after a study by the anti-corruption commission estimated the commercial value of undeclared logging was $60.7 billion to $81.4 billion between 2003 and 2014.

The study released in October estimated the government's loss of revenue from royalties at $6.5 billion to $9 billion over those years.

Dian Patria, head of corruption prevention for natural resources at the Corruption Eradication Commission, says Monday that top officials from other ministries and agencies are supporting the plan.
