In a world increasingly focused on reducing greenhouse gas (GHG) emissions, the European Union (EU) is leading the charge with expanded climate regulations that go beyond carbon dioxide (CO2) emissions alone. The 2024 amendments to Implementing Regulation (EU) 2018/2066 will require airlines to track and report not only CO2 but also non-CO2 emissions, including nitrogen oxides (NOx) and the formation of contrails. Although often overlooked, these non-CO2 effects have a substantial impact on global warming. The EU’s latest regulatory framework is designed to hold airlines accountable for their complete environmental footprint. 

For airlines operating within the European Economic Area (EEA), this means adapting to a more comprehensive scope of emissions reporting. The new rules, which take effect in 2025, will require changes to how emissions are monitored, reported, and managed. In this article, we’ll explore the key elements of the new regulations, how they’ll affect airlines, and how VURDHAAN can guide your organization through these changes with tailored sustainability solutions. 

Why Non-CO2 Emissions Matter 

While CO2 emissions from burning jet fuel are widely recognized as a major contributor to climate change, non-CO2 emissions—such as NOx, water vapor, and contrails—also play a significant role. NOx emissions contribute to the formation of ozone, a powerful greenhouse gas, and contrails can trap heat in the Earth’s atmosphere, amplifying global warming. 

Recent research suggests that the warming potential of non-CO2 emissions may match or even surpass CO2 emissions alone, making it essential for the aviation sector to address these effects. The EU’s new regulations reflect this understanding by requiring airlines to account for both CO2 and non-CO2 emissions in their environmental reporting. 

Key Changes in the EU’s 2024 Non-CO2 Regulations 

Several critical amendments in the 2024 EU regulations will reshape how airlines monitor and report emissions: 

1. CO2-Equivalent (CO2e) Reporting for Non-CO2 Effects 

Airlines will now be required to report non-CO2 emissions, such as NOx and contrails, in terms of CO2-equivalents (CO2e). This standardized metric converts the climate impact of non-CO2 emissions into an equivalent CO2 value, offering a more holistic assessment of an airline’s total environmental footprint. 

2. Global Warming Potential (GWP) Calculations 

The new regulations require airlines to calculate the Global Warming Potential (GWP) of their emissions over three different timeframes: 20 years, 50 years, and 100 years. This approach enhances understanding of the short-term and long-term climate impacts of both CO2 and non-CO2 emissions and encourages airlines to minimize their long-term environmental effects. 

3. Non-CO2 Aviation Effects Tracking System (NEATS) 

The EU is also introducing the Non-CO2 Aviation Effects Tracking System (NEATS), an advanced tool that simplifies data collection for airlines. NEATS automates the process of monitoring emissions, flight paths, and fuel consumption, reducing the administrative burden while ensuring compliance with the new regulations. 

How These Changes Will Impact Airlines 

The EU’s expanded focus on non-CO2 emissions represents a transformative shift in environmental responsibility for airlines. Here’s how these regulations will affect your airline: 

1. Expanded Emissions Reporting 

Airlines will need to adopt more sophisticated emissions tracking systems to cover both CO2 and non-CO2 emissions. This comprehensive report will provide a clearer picture of the airline’s overall climate impact. 

2. Heightened Accountability 

With the inclusion of non-CO2 emissions in the regulatory framework, airlines are now accountable for their entire environmental footprint. This will likely prompt a reassessment of sustainability strategies and the adoption of technologies or operational adjustments to reduce non-CO2 emissions. 

3. Operational Adjustments to Minimize Non-CO2 Effects 

Airlines may need to optimize flight paths and operational procedures to reduce NOx emissions and avoid altitudes that promote contrail formation. These adjustments will help minimize the overall climate impact of their operations. 

4. Driving Innovation in Fuel and Technology 

The EU’s non-CO2 regulations are expected to stimulate innovation in sustainable aviation fuels (SAFs) and advanced aircraft technology. Airlines that invest in SAFs, which generate fewer NOx emissions, will be in a stronger position to meet regulatory standards while enhancing sustainability.

The aviation industry is rapidly advancing its efforts to reduce its environmental impact, but new challenges are emerging in the race toward a sustainable future. One such challenge, highlighted at the 2024 Congress of the International Council of the Aeronautical Sciences by Axel Krein, executive director of the European Union’s Clean Aviation public-private partnership, is the need for more in-depth research on non-CO2 emissions. These emissions, including contrails, nitrogen oxides (NOx), and other particles released at high altitudes, could have a significant climate impact—and policies regulating them are already on the horizon.

Non-CO2 Emissions and the EU Emissions Trading Scheme

Krein’s call for urgency comes ahead of the upcoming changes to the EU Emissions Trading Scheme (ETS), which is set to introduce monitoring, reporting, and verification (MRV) for non-CO2 emissions starting in 2025. The goal is to inform a decision by 2027 on whether non-CO2 emissions should be incorporated into the ETS. While there is high confidence that CO2 contributes significantly to climate change, the role of other emissions like NOx and contrails is less understood.

These uncertainties pose a dilemma for the industry, as strategies to reduce CO2 emissions can sometimes exacerbate non-CO2 impacts, and vice versa. For example, avoiding contrail formation by rerouting flights may lead to increased CO2 emissions due to longer distances flown. The trade-offs between reducing contrails or NOx and cutting CO2 emissions are not yet clear, making it difficult to craft effective policies.

The Need for Comprehensive Research

Krein’s message is clear: the aviation community needs to intensify its research into the climate impacts of non-CO2 emissions to reduce uncertainty. This research is not only crucial for identifying the right technologies and operational strategies for reducing aviation’s climate impact, but it is also essential for the development of accurate and fair regulations.
