What is PTBAE? Indonesia's emission cap approval for compliance companies, PTBAE-PU allowances traded on IDXCarbon, and how they relate to offsets.
PTBAE (Persetujuan Teknis Batas Atas Emisi, technical approval of the emission cap) is the emission limit Indonesia’s government sets for a regulated business over a compliance period. The tradable form for businesses, PTBAE-PU (for pelaku usaha), is the emission allowance that compliance companies receive and can trade on IDXCarbon.
Why it matters
PTBAE is the core of Indonesia’s emissions trading system. It creates a cap-and-trade market: companies emitting below their cap can sell surplus allowances, and those above it must buy allowances or use offsets. That demand is a potential source of buyers for SPE-GRK, including from forestry, depending on rules on offset use.
How it works
- The ministry sets an emission cap for a sector and allocates PTBAE-PU to each compliance company for the period.
- Companies monitor and report actual emissions.
- Surplus allowances can be sold; deficits are covered by buying PTBAE-PU or using SPE-GRK offsets within limits.
- PTBAE-PU is traded on IDXCarbon and recorded in the national registry.
- Surrender to the ministry for compliance happens outside the exchange.

Indonesia and Southeast Asia angle
The system started with coal-fired power plants connected to the PLN grid and is expected to widen to other sectors over time. Its scale and the share of offsets it allows will shape domestic demand for forestry units. For land-based project developers, PTBAE matters less as a unit to hold and more as a driver of potential buyers. Check current ministerial rules for which sectors are covered and offset limits.
Allowance prices and the volume of trading depend on how tight the caps are. Loose caps mean surplus allowances and low prices; tighter caps over time would raise demand for both allowances and offsets.
Common mistakes
- Treating PTBAE-PU as an offset; it is an allowance.
- Assuming forestry companies receive PTBAE.
- Assuming unlimited offset use against allowances.

Frequently asked questions
Who receives PTBAE-PU?
Companies classified as compliance companies, starting with coal-fired power generation, receive PTBAE-PU allocations from the relevant ministry.
Can PTBAE-PU be surrendered through IDXCarbon?
No. Surrender of PTBAE-PU to the ministry for compliance is not done through IDXCarbon. Retirement of SPE-GRK for offset claims can be.
