Cross-sectoral correction factor
Under the EU Emissions Trading System (EU ETS), a uniform cut to free allocation, used when installations' free allocation would exceed the maximum amount available. For each year from 2026 to 2030, it is 100%, so it cuts nothing.
- Who it applies to
- Incumbent installations that receive free allocation: their final yearly amount is their preliminary amount multiplied by the factor. The factor also enters the free allocation adjustment under the Carbon Border Adjustment Mechanism (CBAM), which adjusts the number of CBAM certificates to be surrendered.
- Example
- An installation's only sub-installation is the heat benchmark sub-installation from our "Benchmark – EU ETS" entry: 1,000 terajoules (TJ) of measurable heat a year at 31.2 allowances per TJ, serving a sector deemed at risk of carbon leakage and producing no goods covered by CBAM. Its preliminary amount is 31,200 allowances a year, and at 100% the factor leaves it at 31,200 for each year from 2026 to 2030.
- Also known as
- CSCF, uniform cross-sectoral correction factor, correction factor
The ETS Directive (Directive 2003/87/EC) keeps
Once EU countries have notified their installations' preliminary amounts, the Commission determines the factor by comparing their sum with the amount available. Each incumbent installation's final yearly amount is its preliminary amount, the sum of its
Implementing Decision (EU) 2026/1862 sets the uniform cross-sectoral correction factor at 100% for each year from 2026 to 2030. Its reason: part of the additional amount of up to 3% is used to raise the maximum for 2021 to 2030, so no cut is needed.
Under the Carbon Border Adjustment Mechanism (CBAM), the free allocation adjustment to the number of CBAM certificates uses the cross-sectoral correction factor that the Commission determines under Article 14(6) of the Free Allocation Regulation.
