European Union Emissions Trading System launch (2005)
January 2005What Happened
The European Union launched the world's first major cap-and-trade carbon market, covering roughly 11,000 power plants and industrial facilities across 25 member states. In its first phase, governments over-allocated free emission allowances based on industry self-reported data, crashing the price of carbon permits to near zero by 2007.
Outcome
Phase 1 carbon prices collapsed from over EUR 30 to under EUR 1 as the surplus of free allowances became apparent. Critics declared emissions trading a failed experiment.
The EU reformed the system repeatedly — tightening caps, auctioning permits, and introducing a Market Stability Reserve in 2019. By 2023, prices exceeded EUR 80 per tonne and EU emissions covered by the system had fallen roughly 47% from 2005 levels. The system became the global benchmark for carbon pricing.
Why It's Relevant Today
India's intensity-based design and concern about credit surpluses echo the EU's early over-allocation problems. The EU experience shows that a carbon market can fail on launch and still evolve into an effective decarbonization tool — but only with aggressive reforms and price stability mechanisms that India has not yet introduced.
