Indonesia’s wildfire haze blankets Southeast Asia

Nature & Climate Perspective

**Catastrophic wildfire outbreaks across Indonesian peatlands and tropical forests severely undermine regional terrestrial carbon sinks and present acute permanence and reversal risks. **

• Combustion of mega-biodiverse peat-swamp ecosystems destroys irreplaceable habitats for endangered flora and fauna, fracturing tropical wildlife corridors.
• The burning of subterranean, carbon-dense peat deposits triggers massive pulses of unmitigated greenhouse gases, turning historic LULUCF sinks into net-emissive carbon sources.
• Persistent transboundary haze and severe thermal degradation damage topsoil microbiology, impeding long-term vegetative regeneration and hydrologic stability.

Market & Policy Outlook

**Transboundary wildfire events directly threaten registry buffer pool solvency under ICVCM Core Carbon Principles and introduce severe delivery risk for Article 6 compliance mechanisms. **

• National regulators are expected to tighten fire-management policies, potentially restricting international authorization of ITMOs under Article 6.2 and 6.4 due to unquantified non-permanence liabilities.
• Credits from regional nature-based REDD+ projects risk failing ICVCM CCP permanence assessments, resulting in tier-split market pricing, widened bid-ask spreads, and potential buffer pool depletions.
• Multinational buyers targeting voluntary beyond-value-chain mitigation face elevated greenwashing and integrity scrutiny under SBTi when holding Southeast Asian forest offsets subject to unhedged reversal risks.
