Why Emission Reporting Matters for Aviation in 2026?

The aviation industry, a crucial driver of global connectivity and economic growth, faces increasing pressure to address its environmental impact. From passenger concerns about “flight shame” to ambitious regulatory targets, the spotlight is firmly on how airlines are managing and communicating their emissions. This is where robust emission reporting becomes not just a compliance requirement, but a vital tool for transparency, accountability, and ultimately, a more sustainable future for air travel.

Emission reporting serves multiple critical functions for the aviation sector:

• Transparency and Accountability: It informs the public and policymakers about airlines’ sustainability achievements in a comprehensive way. This is particularly important given the industry’s significant contribution to CO2 and non-CO2 emissions. Without clear reporting, it’s difficult for stakeholders to assess genuine progress towards climate goals.
• Regulatory Compliance: European airlines operate under evolving regulatory frameworks like the EU Emissions Trading System (EU ETS), Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), and the Corporate Sustainability Reporting Directive (CSRD). These mandates require strict monitoring, reporting, and verification of emissions. Non-compliance can lead to penalties and undermine investor trust.
• Stakeholder Engagement and Reputation: Investors, corporate clients, and daily travellers are increasingly climate-informed and prefer to be associated with airlines perceived as green. Comprehensive and transparent reporting can enhance an airline’s reputation, attract investment, and even provide a competitive advantage.
• Strategic Decision-Making: For airlines, understanding their emissions profile is essential for developing effective decarbonization strategies. This includes identifying major sources of carbon emissions, prioritizing solutions, and tracking the impact of initiatives like fuel efficiency improvements or the adoption of Sustainable Aviation Fuels (SAF).
• Addressing Greenwashing and Greenhushing: Consistent and standardized reporting helps to counteract practices like “greenwashing” (selectively reporting favourable data) and “greenhushing” (under-communicating genuine sustainability achievements).

The international standard for reporting firm emissions is the GHG Protocol Corporate Standard, which categorizes emissions into three scopes:

• Scope 1 Emissions: These are direct emissions from owned or controlled sources, primarily the burning of jet fuel in aircraft. This is the most consistently reported KPI by the aviation industry.
  • Calculation: The CO2 emissions for a flight are typically calculated by multiplying the total fuel consumed by an emission factor (e.g., 3.16 kg CO2/kg fuel).
• Scope 2 Emissions: These are indirect emissions from the generation of purchased energy, such as electricity used for ground operations at airports or offices.
• Scope 3 Emissions: These are all other indirect emissions that occur in the value chain of the reporting company, both upstream and downstream, and are not included in Scope 2. This can include emissions from the production of purchased goods and services, capital goods, fuel- and energy-related activities (e.g., fuel extraction and refining), and even employee commuting.

While most airlines consistently report Scope 1 emissions, there are persistent gaps in reporting Scope 2 and particularly Scope 3 emissions. Studies show that Scope 3 emissions can be significant, potentially amounting to one-third of Scope 1 emissions. The lack of standardized definitions and methodologies for these categories makes comprehensive comparison challenging.

Moving Forward

The aviation industry is on a path towards decarbonization, and accurate, comprehensive emission reporting is paramount. As regulatory frameworks evolve and stakeholder expectations grow, airlines are encouraged to:

• Adopt unified technical standards for all mandatory Key Performance Indicators (KPIs), especially for Scope 2 and 3 emissions and SAF lifecycle calculations.
• Develop voluntary common standards for non-mandatory KPIs to improve comparability.
• Invest in digital open-access reporting platforms to reduce administrative burden and improve data consistency.

By embracing transparent and standardized emission reporting, the aviation industry can build trust, demonstrate genuine progress, and effectively navigate its journey towards a sustainable future.
