The focus is on the technical, operational, and strategic steps taken to reach this milestone, the verification process, and the potential impact on global airport sustainability efforts. The analysis also considers the limitations and future directions of Finavia’s climate program.
Methodology
The review draws on official statements from Finavia, technical documentation from the Airport Carbon Accreditation (ACA) program, and public announcements from key partners such as Neste. Data is presented in a structured format, with visual descriptions to aid understanding. Comparisons are made with industry trends and other airports’ progress toward net-zero emissions. Evidence-based conclusions are provided, and the analysis highlights both achievements and ongoing challenges.
Key Findings
- Helsinki Airport became the fifth Finavia airport to achieve net-zero carbon emissions, certified at Level 5 by the ACA program as of June 9, 2025.
- The airport reduced its direct (Scope 1 and 2) emissions by over 90% and neutralized the remainder through certified carbon removal projects.
- All energy used at the airport, including electricity, heating, and fuel for vehicles, now comes from renewable or CO₂-free sources.
- The achievement sets a benchmark for the aviation industry, with only about twenty airports worldwide reaching this level of certification.
- Finavia’s climate strategy is ahead of both national and European targets, aiming for net-zero across all its airports by the end of 2025.
Data Presentation and Visual Descriptions
To help readers visualize the process, imagine Helsinki Airport as a complex system with multiple sources of emissions. These include:
- Lighting: Runways and aprons require powerful lights, traditionally powered by fossil fuels.
- Heating and Ventilation: Large terminal buildings need constant heating and air circulation, often using district heating systems.
- Vehicles and Equipment: Maintenance vehicles, snowplows, and emergency generators have historically run on diesel.
Visual Description: Picture a flowchart where each emission source is connected to a solution:
– Lighting → Switched to renewable electricity (wind and solar)
– Heating → Transitioned to renewable district heating
– Vehicles → Converted to run on Neste MY Renewable Diesel, made from waste materials
Each solution feeds into a central goal: reducing emissions as close to zero as possible. Any remaining emissions are offset by projects that remove carbon from the atmosphere, such as tree planting.
Comparisons, Trends, and Patterns
Industry Context
Globally, airports are significant sources of carbon emissions, mainly due to energy use in buildings and ground operations. The ACA program, managed by Airports Council International, provides a framework for airports to measure, reduce, and offset emissions. Level 5 certification, achieved by Helsinki Airport, is the highest standard, requiring:
- At least 90% reduction in direct emissions (Scope 1 and 2)
- Neutralization of residual emissions through approved carbon removal projects
- Commitment to net-zero Scope 3 emissions (indirect emissions, such as those from suppliers and passengers) by 2050
- Independent third-party verification
Trend: While many airports have set net-zero targets for 2030 or 2050, only a handful have achieved full certification. Finavia’s progress is notable, as five of its airports have already reached this milestone.
Pattern: The use of renewable energy and fuels is becoming standard practice among leading airports. However, the transition is often slow due to technical, financial, and regulatory challenges.
Evidence-Based Conclusions
Technical Implementation
Finavia’s approach at Helsinki Airport involved several coordinated actions:
- Switching to Renewable Electricity
- The airport uses only certified wind power.
- On-site solar power plants, expanded since 2017, provide additional clean energy.
- LED lighting and automation systems reduce overall energy consumption.
- Transitioning to Renewable Heating
- District heating, which warms the airport’s buildings, is now sourced from renewable energy.
- This move eliminated a major source of fossil fuel emissions.
- Decarbonizing Vehicles and Equipment
- All field vehicles and maintenance equipment run on Neste MY Renewable Diesel.
- This fuel is made from waste and leftover materials, cutting greenhouse gas emissions by about 90% compared to fossil diesel.
- The switch is especially important for heavy machinery that cannot easily be electrified.
- Offsetting Residual Emissions
- For emissions that cannot be eliminated (about 2%), Finavia invests in carbon removal projects.
- These include tree-planting initiatives that meet international standards.
- Verification and Certification
- All results are independently verified as part of the ACA Level 5 certification process.
- This ensures transparency and credibility.

Broader Impact and Stakeholder Perspectives
Finavia’s Leadership
Kirsi Pitkäranta, Vice President of Sustainability at Finavia, stated, “Reaching net zero carbon emissions is an ambitious climate goal. Only about twenty airports globally have achieved net zero status under Airport Carbon Accreditation, and five of them are Finavia airports.” This highlights Finavia’s leadership in the field.
Industry Partnerships
Joni Pihlström from Neste emphasized the importance of collaboration: “This achievement by Helsinki Airport is a testament to what is possible when ambitious climate goals are paired with practical and immediate solutions.”
National and Regional Alignment
Finavia’s targets are more ambitious than Finland’s national goal of carbon neutrality by 2035 and the Helsinki-Uusimaa region’s goal for the same year. The city of Vantaa, where Helsinki Airport is located, aims for carbon neutrality by 2030.
European Context
Finavia is part of a European commitment to have 100 carbon-neutral airports by 2030. As of 2019, Finland 🇫🇮 had already reached 20% of this target, with Finavia airports making up a significant share.
Limitations and Challenges
Scope of Certification
The net-zero status applies only to emissions under the airport’s direct control (Scope 1 and 2). This does not include aircraft emissions or those from suppliers and passengers (Scope 3). While Finavia has committed to addressing Scope 3 emissions by 2050, these remain a significant challenge for the industry.
Technical and Economic Barriers
– Some airport machinery cannot yet be fully electrified.
– Renewable fuels are more expensive than fossil fuels.
– Carbon removal projects must meet strict criteria to be recognized under the ACA program.
