Indonesia is the world’s top coal exporter. However, limitations in the supervision of its extraction may be placing the country at risk of massive financial losses and environmental damage. That’s  the conclusion of  an investigation, recently carried out by the country’s Supreme Audit Agency. The audit claims that  more than 1,000 mining companies across the country have failed to comply with environment-related requirements.
Among London-listed companies involved in coal projects in Indonesia are BHP Billiton and Churchill Mining.
