Toward Net-Zero Aviation: How renewable energy procurement offers airports immediate, practical solutions for cleaner air travel

Across Europe, airports and aviation authorities are setting bold net-zero targets to reduce their environmental footprint and improve air quality in surrounding communities. Electrifying ground operations and sourcing sustainable energy for terminals and support infrastructure are emerging as practical, immediate steps toward decarbonising the aviation sector.

While airlines face longer timelines to decarbonise flight operations, airports can act now. From electric ground vehicles to energy-efficient terminals, the shift to renewable energy is key to meaningful emissions reductions. But to unlock these benefits, airports must secure a reliable and cost-effective supply of clean energy.

Power-Purchase Agreements: A runway to sustainability

Power-purchase agreements (PPAs) are gaining traction as a preferred mechanism for airports to source renewable energy. These long-term contracts allow operators to lock in stable electricity prices while directly supporting new wind and solar projects. PPAs not only reduce operational emissions—they also shield airports from energy market volatility and contribute to Europe’s broader energy transition.

Several aviation hubs are already putting PPAs into action:

• Amsterdam Schiphol Airport signed a multi-year solar PPA to power its terminals and electric ground fleet, helping it progress toward its goal of becoming zero-emission by 2030.
• Frankfurt Airport partnered with a regional wind energy provider for a 100 GWh PPA, enabling it to electrify baggage handling systems and reduce Scope 2 emissions.
• Brussels Airport recently announced a solar PPA covering 60% of its terminal energy needs, supporting its ambition to become climate-neutral by 2035.

Beyond Terminals: PPAs Powering Aviation Infrastructure

Renewable energy procurement isn’t limited to airport operations. PPAs are increasingly being used to power large-scale aviation infrastructure projects—from new terminals to maintenance hangars and logistics hubs.

For example:

• The construction of Paris Charles de Gaulle’s Terminal 4 includes a 30 GWh solar PPA to power cranes, lighting, and temporary facilities.
• Heathrow Airport’s cargo expansion zone is being built with renewable electricity sourced through a wind PPA, reducing embodied carbon in construction.

These examples show how PPAs are helping aviation stakeholders meet climate goals while managing costs and improving resilience.

As PPAs become central to aviation’s sustainability strategy, energy buyers from airports and airlines are joining RE-Source 2025 in Amsterdam—Europe’s leading event for corporate renewable energy sourcing.

From expert-led sessions on accessing PPAs and understanding the Greenhouse Gas Protocol, to networking with energy providers and peers, RE-Source 2025 offers a comprehensive program tailored to the sector’s needs.

A special Energy Buyers Day on 3 November provides new participants with hands-on guidance and connections. Registration is open, and first-time buyers can join for free.
