Southern China braces for more torrential rain after Typhoon Saudel triggers flooding

Nature & Climate Perspective

**Recurrent severe storms and flooding in Southern China severely compromise regional carbon stocks and elevate non-permanence risks across terrestrial and coastal ecosystems. **

• Inundation and severe soil runoff trigger physical degradation in regional river basins, disrupting local biodiversity corridors and destabilizing fragile riparian habitats.
• Extreme hydrologic stress and biomass loss across southern forestry regions threaten ongoing carbon sequestration and jeopardize coastal Blue Carbon project viability.
• Cumulative storm impacts undermine ecological baseline resilience, posing severe challenges to maintaining long-term carbon storage integrity under ICVCM Permanence criteria.

Market & Policy Outlook

**Escalating physical climate risks in Southern China's economic centers place upward pressure on credit buffer pools and jeopardize corporate Scope 3 decarbonization timelines. **

• Heightened natural disaster frequency demands stricter regulatory stress-testing within national carbon accounting frameworks and Article 6.2/6.4 bilateral transfer mechanisms.
• Voluntary carbon market (VCM) mechanisms face liquidity constraints and rising risk premiums as credit rating agencies reassess reversal risks for LULUCF assets lacking ICVCM-compliant buffer contributions.
• Widespread industrial and agricultural interruptions across the Guangdong and Hainan corridors threaten corporate Scope 3 emissions targets aligned with SBTi standards due to supply chain reconfiguration.
