Southeast Asia

Climate & Economic Context in Southeast Asia

  • Rapid growth + high climate vulnerability.
  • Key emitting sectors: manufacturing, textiles, mining, agriculture.

Vietnam Textile Sector: Impacts & Responses

  • Scale: 3rd3^{rd}-largest global exporter; 15%15\% GDP; 12−30%12{-}30\% world output.
  • Water use: 2,5002{,}500 L per cotton T-shirt.
  • Waste: offcuts, discarded garments; landfill life >200>200 yr → methane.
  • GHG: 4−54{-}5 kg CO2\text{CO}_2 per 250250 g polyester T-shirt.
  • Case evidence: Hue (pollution, later wastewater upgrades); Red River Delta (80%80\% untreated effluent).
  • Policy: Vietnam Green Growth Strategy → GHG ↓ 15%15\% by 20302030, 30%30\% by 20502050; 100%100\% wastewater treatment by 20302030; renewables 15−20%15{-}20\% of energy by 20302030.
  • Corporate best practice (e.g.
    H&M): ZDHC compliance, recycled fibers, solar roofs, supplier scorecards.
  • Persistent barriers: high tech costs, skill gaps, weak enforcement.

Mining Sector in Southeast Asia: Impacts & Corporate/Economic Responses

  • Resources: nickel, rare earths, tin, coal.
  • Climate & environmental risks: deforestation, landslides, flooding, heat stress, water pollution.
  • Business risks: schedule disruption, infrastructure damage, ESG finance loss.
  • Economics: climate-linked disasters ↓ GDP; productivity drops from heat.
  • Cases:
    • Loei, Thailand (gold): cyanide, arsenic; mine closed after protests.
    • Hpakant, Myanmar (jade): deforestation → landslides; 170+170+ deaths 20202020.
    • Kalimantan/Sumatra, Indonesia (coal): forest loss, CO2\text{CO}_2 rise.
  • Corporate conduct: some denial (Tungkum), partial responsibility (Kingsgate).
  • Regional / national action:
    • Thailand Minerals Act 20172017; mine-closure & rehab rules.
    • ASEAN AMCAP 2021−20252021{-}2025: responsible mining, tech sharing.
    • Enforcement remains domestic → variable effectiveness.

Thailand Agriculture & Climate Interaction

  • Agriculture = major income source & highly climate-sensitive.
  • Main GHGs: methane (rice, livestock) & nitrous oxide (fertilizers, manure).
  • Emission trends 1990−20051990{-}2005: CH₄ + N₂O ↑ 17%17\%; projected 20302030: N₂O ↑ 35−60%35{-}60\%, livestock CH₄ ↑ 60%60\%.
  • Rice sector impacts: up to 16%16\% yield loss; 22 Mt export drop; paddy price fall 30%30\% in 20252025.
  • Adaptations:
    • Community irrigation management.
    • Crop diversification & alternative livelihoods.
    • Farmer training (fertilizer efficiency, low-emission rice).
    • Local early-warning systems.
  • Government support: R&D, finance, extension, stronger climate policy.
  • Key hurdles: low awareness, finance gaps, limited skills, weak crop-insurance uptake.
