Since the ETS introduction, average energy prices for families increased by more than 200%.

Omissions

• The claim does not cite any specific data source, making independent verification difficult.
• Eurostat household electricity price data is only available from 2007 onwards, not from the 2005 ETS introduction, so the exact baseline comparison period is not covered by official statistics.
• The claim refers to 'average energy for families,' which is ambiguous — it could encompass electricity, natural gas, heating oil, and other fuels, each with different price trajectories. No single EU-wide index covering all these energy sources from 2005 exists in readily accessible Eurostat data.
• Eurostat data for H2 2025 shows average household electricity prices at €28.96 per 100 kWh. Even taking the earliest available Eurostat data (2007), the increase to 2025 is far below 200%, suggesting the claim is likely overstated, but the exact 2005 baseline remains unavailable for a definitive comparison.
• Two independent sources or one primary source confirming the claim could not be found.
