The UK is making strides toward decarbonizing the aviation sector with the ongoing consultation on the implementation of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). This consultation addresses two critical aspects: drafting secondary legislation for CORSIA’s offsetting requirements and its interaction with the UK Emissions Trading Scheme (UK ETS). With its global reach and innovative approach, CORSIA represents a vital step in the fight against climate change.
This article explores the consultation’s key proposals, implications for the aviation sector, and how this aligns with the broader decarbonization goals for the UK and beyond.
Understanding CORSIA
CORSIA, developed by the International Civil Aviation Organization (ICAO), is the first global market-based mechanism targeting carbon neutrality in international aviation. It operates in three phases, with the UK actively participating in the pilot phase in 2021.
The scheme aims to achieve ICAO’s climate goal of carbon-neutral growth from 2020 onward by requiring operators to offset emissions above a baseline level. Operators achieve this by purchasing CORSIA Eligible Emissions Units (CEUs) or using sustainable aviation fuels (SAFs) that meet ICAO’s sustainability criteria.
Key Aspects of the Consultation
Draft Legislation for CORSIA Offsetting
The consultation proposes secondary legislation to incorporate CORSIA’s offsetting requirements into UK law. This includes:
- Calculating CO2 offsetting obligations for aeroplane operators annually, using sectoral and individual growth factors.
- Provisions for cancelling emissions units to meet offsetting obligations.
- Penalties for non-compliance, including financial penalties tied to inflation-adjusted metrics.
These measures ensure alignment with ICAO’s Standards and Recommended Practices (SARPs), maintaining consistency with international norms.
Interaction Between CORSIA and UK ETS
One of the most critical elements of the consultation involves addressing the overlap between CORSIA and the UK ETS for flights departing the UK and arriving in the European Economic Area (EEA) or Switzerland. Without a clear strategy, operators face the risk of double compliance costs.
The consultation outlines two policy options:
- UK ETS Only: CORSIA offsetting would not apply to flights covered by the UK ETS.
- Price-Based Hybrid: Both schemes would apply, with compensation mechanisms to offset additional compliance costs for operators.
The government seeks to balance its international obligations under CORSIA with the integrity of the UK ETS, ensuring operators are not penalized unfairly while maintaining robust emissions reduction incentives.
The Role of Sustainable Aviation Fuels
CORSIA highlights the potential of SAFs to reduce offsetting obligations. By using fuels with lower lifecycle emissions, operators can significantly reduce their carbon footprint. SAFs represent a cornerstone of the UK’s aviation decarbonization strategy, complementing market-based mechanisms like CORSIA and the UK ETS.
Implications for the Aviation Sector
Compliance and Financial Considerations
The proposed legislation introduces a clear framework for monitoring, reporting, and offsetting emissions. While the consultation provides flexibility in certain areas, such as penalties for calculation errors, operators must prioritize compliance to avoid financial repercussions.
The interaction between CORSIA and the UK ETS poses significant financial and administrative challenges. Operators must navigate the complexities of both schemes while ensuring they meet emissions reduction targets.
Opportunities for Innovation
The consultation’s emphasis on SAFs and other low-carbon technologies presents an opportunity for operators to invest in innovative solutions. By adopting cleaner fuels and improving operational efficiency, airlines can reduce compliance costs and enhance their sustainability credentials.

Aligning with Global Climate Goals
The UK’s implementation of CORSIA and the UK ETS reflects its commitment to international climate action and net-zero ambitions. By incorporating lessons from the EU ETS and other global initiatives, the UK can set a benchmark for effective aviation decarbonization.
Collaboration between governments, regulators, and industry stakeholders will be essential to addressing challenges and maximizing the benefits of these schemes.
Conclusion
The consultation on CORSIA implementation marks a significant step in the UK’s journey toward sustainable aviation. By integrating global standards with domestic policies, the UK aims to create a cohesive framework that balances environmental integrity with economic competitiveness.
As operators prepare to adapt to these changes, they must prioritize compliance, invest in innovation, and embrace sustainable practices. Together, these efforts will ensure that aviation contributes to a cleaner, greener future.
