A New Phase in Global Aviation Climate Strategy The International Civil Aviation Organization (ICAO) has released the 6th edition of its CORSIA States for Chapter 3 State Pairs list, confirming that 130 countries will participate in the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) starting 1 January 2026. […]

Seventh Edition Introduces New Methodologies and Emission Factors The International Civil Aviation Organization (ICAO) has published the seventh edition of its regulatory guidance on default life cycle emissions values under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). This update, approved in June 2025, introduces a series of

6th Edition Introduces Expanded GHG Reduction Framework In June 2025, the International Civil Aviation Organization (ICAO) released the 6th edition of the CORSIA Methodology for Calculating Actual Life Cycle Emissions Values, marking a significant evolution in its approach to aviation fuel emissions accounting. This latest update strengthens the Carbon Offsetting

Introduction of Fourth Edition Standards In June 2025, the International Civil Aviation Organization (ICAO) released the fourth edition of its CORSIA Sustainability Criteria for CORSIA Eligible Fuels, refining the regulatory framework to align with evolving climate and sustainability goals. The updated document plays a critical role in supporting Annex 16,

Introduction to the Update In June 2025, the International Civil Aviation Organization (ICAO) released the 4th edition of its Eligibility Framework and Requirements for Sustainability Certification Schemes (SCS) under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). The revised document introduces stricter oversight mechanisms to enhance credibility, transparency,

A Strategic Step Toward Integrated Climate Action Background: Strengthening Market-Based Climate Solutions Since the launch of the EU Emissions Trading System (EU ETS), the European Union has led the global push for carbon pricing as a key tool to combat greenhouse gas emissions. The UK, after establishing its own ETS

A Defining Moment in European Climate Ambition The European Commission has unveiled a bold and forward-looking climate objective: a legally binding 90 percent reduction in net greenhouse gas emissions by 2040 compared to 1990 levels. This proposal is not just another legislative milestone. It is a layered strategic blueprint for

A New Era for Clean Skies Aviation has long been cast as a high-flier in carbon emissions, with few viable alternatives to fossil-based jet fuel. Yet, a new UK legislative initiative—the Sustainable Aviation Fuel Bill 2024-25—is setting a course toward change. Introduced in May 2025, this bill offers more than

A Quiet Revolution in Carbon Monitoring In an era where climate consciousness is reshaping every sector, the aviation industry is navigating one of its most intricate transitions yet. While headlines often spotlight technology and alternative fuels, a more subtle but equally transformative change is unfolding—harmonization of emissions monitoring through international

Reframing the Role of Refineries Far from being relics of the fossil fuel age, modern refineries are rapidly positioning themselves as catalysts for a lower-carbon future. According to the International Air Transport Association (IATA), the energy transition is not merely about shifting inputs but reimagining the refinery itself—as a versatile

Introduction to ReFuelEU Aviation Compliance ReFuelEU Aviation, a key regulation under the EU’s Fit for 55 climate framework, aims to accelerate the uptake of sustainable aviation fuels (SAFs). For the 2025 reporting cycle, a new list identifies aviation fuel suppliers falling within the regulation’s scope, bringing greater clarity to compliance

Driving Precision in Climate Impact Assessment In May 2025, the European Commission published a critical document aimed at enhancing the monitoring, reporting, and verification (MRV) of aviation’s non-CO₂ effects. As climate science advances, the aviation sector is under growing pressure to measure its full environmental footprint—not just carbon dioxide. These

Overview of the Update The European Commission has released an updated directory of competent authorities designated by each Member State to enforce Regulation (EU) 2023/2405, widely known as ReFuelEU Aviation. This legislation is central to the EU’s broader decarbonisation agenda, promoting a structured uptake of Sustainable Aviation Fuels (SAF) across

A Turning Point in Climate and Trade Strategy In a defining moment for European climate diplomacy, the UK and the EU have agreed to link their Emissions Trading Schemes (ETS). Announced at the UK-EU Reset Summit on 19 May, the agreement promises substantial financial savings, simplified compliance, and strategic alignment
