Top 10 Airlines in Europe with Highest Emissions Under Fire in Report Advocating for Revision of Carbon Market
Supercharge Climate Legislation: Curb Aviation Emissions and Generate Billions for Green Transition
Ready to take a look at the polluting culprits in the European skies? Here's your lowdown on the top offenders and the most carbon-guzzling flight routes. But first, let's discuss why it's crucial to hold airlines accountable for their emissions!
In 2024, 8.4 million flights departed from European airports, spewing out an eye-watering 187.6 million tonnes of CO2[1]. That's a whopping 96% of the pre-pandemic flight numbers and a staggering 98% of emissions[1].
So, who's responsible for this environmental madness? Ten airlines alone accounted for 40% of the European aviation emissions, with Ryanair leading the pack with a staggering 9% share[1][5]. Lufthansa and British Airways followed closely, each contributing around 6% and 3%, respectively[1][5].
However, it's not all doom and gloom. Campaign group Transport & Environment (T&E) claims that Europe can turn the tables and revamp its aviation sector, all while generating billions for the green transition[1][2]. The secret? Properly pricing aviation's pollution and expanding the scope of key legislation to cover all departing flights.
Admittedly, the current European Union (EU) carbon market rules are "riddled with exemptions," leaving airlines free to dodge the true cost of their pollution[1]. In 2024, according to T&E's analysis, the sector avoided paying for 70% of the emissions it caused[1]. The consequences? A mockery of airlines' pledges to transition to greener practices after COVID-19[1].
An upcoming review of EU carbon markets next year presents the perfect opportunity to correct this loophole, says Krisztina Hencz, aviation policy manager at T&E[1]. Ensuring airlines fully account for their pollution will not only drive down emissions but also generate revenue, fueling the development of sustainable aviation fuels (SAFs) and eco-friendly aircraft[1].
Now, let's dive into the most polluting flight routes from Europe. Airlines currently only pay for emissions for flights within the European Economic Area (EEA), the UK, and Switzerland. However, it's long-haul journeys that are the real culprits.
The highest-emitting routes departing Europe in 2024 were all intercontinental. TheLondon-New Yorkroute emerged as the most polluting, with over 1.4 million tonnes of CO2 released for departing flights[1]. London to Dubai (1.2Mt CO2) and London to Singapore (1.1Mt CO2) came in second and third, respectively[1].
Surprisingly, the first EU-originating flight to appear in the ranking was the Frankfurt-Shanghai route in 5th place, releasing 0.8 million tonnes of CO2 for departing flights[1]. This means that no airline had to pay for emissions on the most polluting routes departing from Europe[1]. T&E believes this is a "fundamental flaw" and a missed opportunity[1].
Extending the scope of Europe's carbon markets to all departing flights would deliver significant climate benefits and generate revenues, according to T&E[1]. An extension of the EU and UK ETS in 2024 could have generated an additional €7.5 billion, supporting the development of eco-friendly technologies like SAFs and electric and hydrogen aircraft[1].
