Record-breaking wildfires in Canada

Nature & Climate Perspective

**Record-breaking Canadian wildfires represent a catastrophic ecological reversal, transitioning vast boreal carbon sinks into net emissions sources and threatening circumpolar biodiversity. **

• Severe burn severity and crown fires have incinerated old-growth boreal habitats, destabilizing keystone wildlife corridors and jeopardizing fragile sub-Arctic biodiversity.
• The combustion of dense peat layers and biomass releases gigatons of stored carbon, directly destabilizing long-standing LULUCF flux baselines and reversing decadal sequestration gains.
• Post-fire reduction in forest canopy albedo and loss of organic ground insulation accelerate discontinuous permafrost thaw, triggering compounding environmental degradation and sustained methane emissions.

Market & Policy Outlook

**The scale of physical reversals directly challenges ICVCM Core Carbon Principles regarding permanence, threatening the liquidity of nature-based credits and forcing structural changes under SBTi guidance. **

• Sovereign LULUCF accounting deficits could restrict host country willingness to issue Corresponding Adjustments under Article 6.2 and Article 6.4, constraining the supply of cross-border ITMOs.
• Massive draws on multi-registry pooled buffer reserves to cover catastrophic reversals breach ICVCM CCP permanence thresholds, driving a severe pricing divergence between afforestation/reforestation credits and durable technical removals.
• Corporates navigating SBTi validation face heightened scrutiny over the durability of forest-carbon compensations, accelerating capital reallocation toward direct Scope 3 emissions reductions rather than off-chain offsets.
