Indonesia’s national oil and gas company is planning to issue its maiden green bonds within a year as it moves to secure funds to hit a 10GW renewables target, with geothermal developments high on its agenda.

Pertamina finance director Emma Sri Martini said the bonds would help expand the group's green energy business to contribute between 10% and 15% of its total revenue within five years, compared to the current figure of less than 5%.
