Official name: EU Emissions Trading System
Citation: Directive 2003/87/EC of the European Parliament and of the Council (as amended) establishing a system for greenhouse gas emission allowance trading
Year / status: In force. Legal spine: Directive 2003/87/EC as amended.
What it does
Creates a Union-wide market in emission allowances for covered installations and aviation (and, under later reforms, further sectors as amended). The cap falls over time; operators surrender allowances against verified emissions. Links and neighbouring systems are policy choices around the Directive, not automatic global coverage.
Where it applies / status
In force across the EU (and linked arrangements where agreed). Legal spine: Directive 2003/87/EC as amended; Commission “What is the EU ETS” hub summarises current design. Use EUR-Lex consolidated text for citation hygiene when amending packages land.
Documented benefits or intended effects
Intended: put a price on covered GHG emissions and cut them under a falling cap. Documented system outcomes belong in EEA/Commission ETS reports: cite those for tonne figures; do not invent.
Caveats
Coverage is sector-limited; free allocation, carbon leakage rules, and price volatility are design features under debate. EU ETS is not the Paris Agreement and not a household fuel duty. Do not merge with EUDR or Nature Restoration on one card.
