EU CBAM (Carbon Border Adjustment Mechanism) เริ่ม full operation ปี 2026 — ผู้นำเข้าจาก non-EU ต้องประกาศ embedded carbon + ซื้อ certificate ตามราคา EU ETS · Thailand HVAC OEM (Daikin, Mitsubishi, Carrier, Trane, LG, Samsung) ที่ส่งออกไป EU ต้องเตรียม LCA documentation + emission reduction roadmap · บทความนี้อธิบายผลกระทบ + วิธีที่ induction brazing ลด CBAM cost
What is CBAM?
CBAM = Carbon Border Adjustment Mechanism · EU regulation จุดประสงค์:
- Prevent carbon leakage — บริษัท EU ย้ายไปประเทศที่ regulation อ่อนกว่า
- Level playing field — domestic EU vs imported product
- Drive global emission reduction — ผู้ส่งออกต้อง cleaner
Phase Timeline
- 2023-2025: Reporting only (transitional phase)
- 2026: Financial obligation begins — buy CBAM certificate
- 2026-2034: Phase-out free EU ETS allowance progressively
- 2034: Full CBAM application — no free allowance
Coverage — สินค้าที่ Affected
| Sector | Initial 2026 | HVAC Relevance |
|---|---|---|
| Cement | ✓ | Low (foundation only) |
| Iron & Steel | ✓ | HIGH — compressor housing, structure |
| Aluminium | ✓ | HIGH — heat exchanger, fin |
| Fertilizer | ✓ | None |
| Hydrogen | ✓ | None (yet) |
| Electricity | ✓ | Indirect |
| Organic Chemicals | 2030+ | Refrigerant |
| Finished Products | 2030+ likely | HIGH — full HVAC unit |
Thailand HVAC Export to EU — Stake
Thailand เป็น manufacturing hub สำหรับ AC unit + components ที่ส่งออกไป EU มูลค่าหลาย billion USD/ปี:
- Daikin Thailand — ASEAN HQ, ส่งออก VRV + R32 unit ไป EU
- Mitsubishi Electric — Rayong plant, EU export significant
- Carrier, Trane — global supply chain
- Tier-3 component makers — Cu tube, heat exchanger, compressor parts
CBAM cost ที่จ่ายเพิ่ม = competitive disadvantage vs จีน/Vietnam ที่ implement low-carbon process · Thailand ที่ act early = first-mover
CBAM Cost Calculation
Cost = (Embedded Carbon × EU ETS Price) - (Origin Country Carbon Price)
- EU ETS price 2026 expected EUR 80-100/tCO₂
- Thailand has no carbon price yet → full ETS apply
- Phase-in: pay 2.5% (2026), 25% (2030), 100% (2034)
Quick Math — 1 AC Unit
- Steel (compressor) ~15 kg × 2.0 kg CO₂/kg = 30 kg CO₂
- Aluminium (fin + heat ex) ~8 kg × 16 kg CO₂/kg = 128 kg CO₂
- Brazing torch: 50 joints × 65 g = 3.25 kg CO₂
- Brazing induction: 50 joints × 7 g = 0.35 kg CO₂
- Total Embedded: torch ~161 kg CO₂ vs induction ~158 kg CO₂
Brazing คิดเป็น ~2% ของ total embedded · BUT direct emission elimination = signal สำคัญต่อ CBAM verifier + brand
Induction Brazing CO₂ Reduction — Math
| Source | Torch (per joint)* | Induction (per joint)* |
|---|---|---|
| Direct combustion CO₂ | 50-80 g | 0 g |
| Indirect (electricity) | 0 g | 5-10 g (TH grid) |
| Filler embedded | 2-3 g | 2-3 g |
| Total per joint | 52-83 g | 7-13 g |
| Reduction | — | ~85% lower |
Renewable PPA + Solar Strategy
Combine induction กับ renewable energy procurement = near-zero brazing emission:
- On-site solar PV — install ที่ plant rooftop
- Off-site PPA (Power Purchase Agreement) — long-term contract กับ renewable developer
- REC (Renewable Energy Certificate) purchase — short-term cover
- Combined cost ใน Thailand 2026: 3-4 THB/kWh (renewable) vs 4-5 THB/kWh (grid)
Documentation Requirements
- Production process LCA (Life Cycle Assessment) ตาม ISO 14040/14044
- Energy consumption per unit (kWh/unit)
- Direct emission per unit (kg CO₂/unit)
- Material certificate (steel/Al supplier carbon)
- Renewable energy certificate ถ้ามี
- Process map + traceability (eQC log)
- Third-party verification by accredited body
- CBAM Quarterly Report bilingual EN+local
Thailand HVAC OEM Roadmap
Critical milestones สำหรับ EU export compliance
Financial Begin
per Joint
No Free Allowance
Competitive Position vs Chinese OEM
- China grid carbon factor ~0.6 kg CO₂/kWh (สูงกว่า Thailand ~0.4)
- จีนหลายโรงงาน yet to switch from torch
- Thailand HVAC ที่ implement induction + renewable = competitive advantage
- เริ่ม early ได้ EU customer preference
- เริ่มล่า paying CBAM penalty ลดมาร์จิ้น
