The Effort Sharing Regulation is mandatory for all EU Member States.
Mandatory Requirements:
Annual compliance with national emission ceilings.
Submission of annual greenhouse gas inventories and progress reports.
Use of approved monitoring and verification systems.
Implementation of domestic policies to achieve reductions.
Exceptions and Flexibility:
Member States can bank, borrow, or trade emission allocations between themselves.
Limited use of LULUCF credits (up to 280 million tonnes CO₂ equivalent EU-wide) is permitted to meet targets.
Temporary exemptions apply for extraordinary circumstances, such as economic shocks or major energy disruptions, subject to Commission approval.
Deep dive
What’s Required
The Effort Sharing Regulation (ESR), Regulation (EU) 2023/857, sets binding national greenhouse gas (GHG) emission reduction targets for EU Member States in sectors not covered by the EU Emissions Trading System (ETS). These include transport, buildings, agriculture, small industries, and waste management, which together account for nearly 60% of the EU’s total emissions.
The updated ESR aligns national targets with the EU’s Fit for 55 Package and the European Climate Law, increasing the overall EU reduction goal to 40% below 2005 levels by 2030 (up from 30% under the previous ESR).
Member States must:
Ensure annual GHG emissions remain within binding national limits (2021–2030).
Monitor, report, and verify emissions annually using EU mechanisms.
Use limited flexibility mechanisms such as trading emission allocations between Member States or using credits from the LULUCF Regulation.
Important Deadlines
10 May 2023: Regulation adopted by the European Parliament and Council.
1 July 2023: Entry into force.
2025: First compliance review covering emissions from 2021–2024.
2030: Achievement of all national reduction targets.
By 2032: Final compliance assessment for the 2021–2030 period.
Current Status
The Effort Sharing Regulation (2023/857) is in force and forms a key component of the EU’s Fit for 55 legislative package. It ensures that all Member States contribute fairly to achieving the EU’s 2030 climate goal and climate neutrality by 2050.
Each country’s reduction target ranges from 10% to 50% below 2005 levels, depending on GDP per capita, with wealthier countries facing higher obligations (e.g., Germany−50%, Denmark−50%, Sweden−50%) and lower-income countries having smaller targets.
The European Environment Agency (EEA) and the European Commission (DG CLIMA) oversee compliance through annual emissions monitoring and progress reports.
Penalties for Non-Compliance
If a Member State exceeds its annual emission allocation:
It must purchase allocations from other Member States or use limited LULUCF credits.
Any unfulfilled obligation is automatically carried forward with a penalty (×1.08 multiplier) to the following year’s allocation.
Continued non-compliance may trigger infringement proceedings by the European Commission under EU law.
Examples of Known Violations
As of 2025, compliance data for the 2021–2023 period is under review. Some Member States, including Ireland and Belgium, have signalled potential shortfalls in meeting interim limits, leading to internal policy adjustments and increased reliance on credit transfers.
