Carbon Footprint — Operations: How does Wizz Air score?

Wizz Air reports Scope 1 (jet fuel combustion) under EU ETS and discloses monthly CO2 emissions in tonnes on its investor relations page. The FY2024 GHG Methodology document confirms operational control boundary and GHG Protocol methodology, with third-party verification by ClimatePartner. However, absolute Scope 1 figures are enormous — T&E estimated 3.7Mt in 2022 rising to approximately 5Mt by 2023, a 40% increase over pre-Covid levels. Jet fuel combustion accounts for 92% of total emissions.

Carbon Footprint — Supply Chain: How does Wizz Air score?

Wizz Air's FY2024 GHG Methodology document reports Scope 3 across multiple categories using hybrid methods including spend-based and consumption-based approaches. Categories 2 and 3 (fuel-related and aircraft expenditures) account for over 88% of Scope 3 emissions. Value chain mapping was described as 'in progress' for CSRD compliance from FY2025. However, actual total Scope 3 tonnage figures were not publicly accessible in search results, and aircraft manufacturing emissions were excluded as as

Emissions Trajectory: How does Wizz Air score?

Absolute emissions are demonstrably rising. T&E data shows Wizz Air's CO2 emissions grew 40% above pre-Covid 2019 levels by 2023, making it one of the fastest-growing polluters in European aviation. While carbon intensity per passenger-km fell to 52.2g (FY2025), the FY2025 sustainability report itself acknowledged intensity increased by 0.2g year-on-year due to operational challenges. The company's growth plan to reach 500 aircraft by 2030 will further increase absolute emissions. Intensity impr

Energy Source: How does Wizz Air score?

Wizz Air's energy consumption is overwhelmingly jet fuel (92% of total emissions from fuel combustion). There is no RE100 membership, no renewable energy PPA, and no disclosed renewable electricity strategy for office operations. SAF usage is negligible — trial flights only occurred in late 2024, and the 10% SAF blend target is for 2030. Presently, SAF constitutes only a minor fraction of fuel used. The company is a massive fossil fuel consumer with no meaningful renewable energy transition unde

Nature & Biodiversity Impact: How does Wizz Air score?

Wizz Air's 2024 CDP submission shows a preliminary biodiversity and nature risk assessment was conducted in preparation for CSRD, using the ENCORE database to map ecologically sensitive areas near base and destination airports. A heat map was prepared evaluating impacts on water resources, biodiversity, ecosystems, resource use, and pollution. However, there is no TNFD-aligned disclosure, no deforestation-free commitment, and no quantified nature footprint. The assessment is at awareness stage o

Resource Use & Waste: How does Wizz Air score?

Wizz Air uses recycled leather (ELeather) seats since 2011, contributing to 77% less landfill and 68% less water consumption compared to traditional leather production. The airline has implemented paperless flight decks saving approximately 6 million sheets of paper annually. On-board waste separation trials were underway. However, there are no measurable circular economy targets, no comprehensive waste reduction reporting, and the company acknowledges limited influence over plastics used in pro

Water Impact: How does Wizz Air score?

Wizz Air's environmental policy commits to monitoring and reducing energy and water usage within its premises. The CDP 2024 disclosure indicates the company is assessing key suppliers based on water stress levels using the Aqueduct Water Risk Atlas for 2030. However, no quantified water footprint, reduction targets, or water consumption data was found in public disclosures. Aviation's direct water impact is relatively low compared to manufacturing sectors, but no specific data is published.

Targets & Commitments: How does Wizz Air score?

Wizz Air's primary target is a 25% reduction in carbon intensity by 2030, with a net-zero by 2050 roadmap aligned with ICAO goals announced in March 2025. However, the SBTi commitment was removed — Wizz Air committed in 2021 but had its commitment removed for failing to submit validated targets. The 25% target is intensity-based, not absolute — while the company plans aggressive growth to 500 aircraft by 2030, absolute emissions will rise significantly. The intensity-only approach and SBTi remov

Transparency & Accountability: How does Wizz Air score?

Wizz Air publishes annual sustainability reports (FY2023, FY2024, FY2025) with third-party verification, discloses to CDP (achieving B score in 2023 with A/A- for Scope 1&2 disclosure), has a Sustainability and Culture Committee at Board level, and publishes monthly CO2 emissions data on its investor relations page. Sustainability-linked performance schemes for the CEO and management team are in place. The company discloses GHG methodology documents and is proactively aligning with CSRD ahead of

Controversies & Red Flags: How does Wizz Air score?

Starting at 8, multiple deductions apply: ASA banned Wizz Air's 'greenest choice in air travel' ad in November 2024 for misleading environmental claims (-2). Wizz Air was among 21 airlines that agreed to change environmental claims after EU CPC greenwashing investigation in November 2025 (-1). InfluenceMap gave Wizz Air a C- score — relatively positive for aviation, supporting EU ETS extension, but the company opposed UK Air Passenger Duty and EU kerosene tax (-1). The airline's CEO in 2021 call

Significant gapsPending Review

Wizz Air is a massive and rapidly growing polluter with rising absolute emissions despite marginal intensity improvements. The airline faces fundamental decoupling between growth plans and climate commitments, relies on intensity-only targets while expanding to 500 aircraft by 2030, and has been caught greenwashing. Transparency on methodology masks the core problem: emissions are accelerating.
