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: 3^{rd}-largest global exporter; 15\% GDP; 12{-}30\% world output.
  • Water use: 2{,}500 L per cotton T-shirt.
  • Waste: offcuts, discarded garments; landfill life >200 yr → methane.
  • GHG: 4{-}5 kg \text{CO}_2 per 250 g polyester T-shirt.
  • Case evidence: Hue (pollution, later wastewater upgrades); Red River Delta (80\% untreated effluent).
  • Policy: Vietnam Green Growth Strategy → GHG ↓ 15\% by 2030, 30\% by 2050; 100\% wastewater treatment by 2030; renewables 15{-}20\% of energy by 2030.
  • 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+ deaths 2020.
    • Kalimantan/Sumatra, Indonesia (coal): forest loss, \text{CO}_2 rise.
  • Corporate conduct: some denial (Tungkum), partial responsibility (Kingsgate).
  • Regional / national action:
    • Thailand Minerals Act 2017; mine-closure & rehab rules.
    • ASEAN AMCAP 2021{-}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{-}2005: CH₄ + N₂O ↑ 17\%; projected 2030: N₂O ↑ 35{-}60\%, livestock CH₄ ↑ 60\%.
  • Rice sector impacts: up to 16\% yield loss; 2 Mt export drop; paddy price fall 30\% in 2025.
  • 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.
