EU Emissions Trading System
Understanding the EU ETS, the world's largest carbon market and key tool for reducing European emissions.
Overview
The EU Emissions Trading System (EU ETS) is the world's first and largest carbon market. It is a cornerstone of EU climate policy, putting a price on carbon emissions and incentivizing reductions across sectors.
How EU ETS Works
Cap and Trade
- Cap: Declining limit on total emissions
- Allowances: Permits to emit (1 allowance = 1 tonne CO2)
- Trading: Buy/sell allowances
- Compliance: Surrender allowances for emissions
Phases
| Phase | Period | Key Features |
|---|---|---|
| Pilot | 2005-2007 | Learning phase |
| Phase 2 | 2008-2012 | Kyoto commitment period |
| Phase 3 | 2013-2020 | Single EU market, auctioning |
| Phase 4 | 2021-2030 | Stricter caps, MSR |
Scope
Sectors Covered
- Power generation: ~95% of EU power sector
- Industry: Steel, cement, chemicals, refineries
- Aviation: Flights within EEA
- Maritime: Shipping (from 2024)
Emissions Covered
- ~40% of EU GHG emissions
- ~8,000 installations
- ~1 billion tonnes CO2/year
Recent Reforms (Fit for 55)
Linear Reduction Factor
- Increased from 2.2% to 4.3% (2024-2027)
- Then 4.4% (2028-2030)
Market Stability Reserve (MSR)
- Addresses price volatility
- Withholds/becomes allowances based on surplus
Free Allocation
- Phased out for aviation (2024)
- CBAM addresses carbon leakage
Expansion
- Maritime: Shipping included (2024)
- Buildings/Road: New system (2027, if launched)
Carbon Border Adjustment Mechanism (CBAM)
Purpose
Prevent carbon leakage by pricing imports:
- Applies to: Steel, cement, aluminum, fertilizers, electricity, hydrogen
- Phased in: 2023-2026 (reporting), 2026-2034 (payments)
- Calculates embedded emissions vs EU ETS price
Business Implications
For Covered Companies
- Compliance: Monitor and report emissions
- Financial: Budget for allowance costs
- Strategic: Decarbonization investments
For Non-Covered Companies
- Supply chain: Expect carbon costs upstream
- Opportunity: Clean technology demand
- Risk: CBAM impacts on exports
Allowance Prices
Historical
- 2005-2007: €20-30
- 2008-2012: €10-15 (surplus)
- 2013-2018: €5-10 (oversupply)
- 2019-2021: €25-90
- 2022-2024: €80-100+
Price Drivers
- Energy prices
- Policy stringency
- Economic activity
- Market speculation
Key Takeaways
- EU ETS is world's largest carbon market
- Cap declines annually, driving emission reductions
- Recent reforms significantly increased ambition
- CBAM addresses carbon leakage
- Price signals drive decarbonization investment
- Covers ~40% of EU emissions
