How Brussels Airport's Digital Twin is Accelerating Net-Zero Emissions by 2030

Brussels Airport is pioneering a major step toward aviation sustainability.

The airport has partnered with Integrated Environmental Solutions (IES) to create a comprehensive digital twin of its most energy-intensive infrastructure. This advanced virtual replica is a core tool in the airport's ambitious plan. The goal is to achieve net-zero emissions by 2030 for all emissions under its control (Scope 1 and 2). This timeline is a significant acceleration of the airport's initial 2050 target. It is also two decades ahead of the industry-wide 2050 deadline set by the International Air Transport Association (IATA).

Digital Twin Technology for Decarbonisation

The Brussels Airport digital twin project is a flagship initiative. It is part of the major EU-funded Stargate initiative. The Stargate program received a €24.8 million grant from the European Green Deal.

Simulating Net-Zero Scenarios

IES created a digital replica of 40 of the airport's most energy-intensive buildings. This model uses physics-based simulation and real-time data. It allows the airport to test various sustainable aviation technologies before physical deployment.

The process is a first-of-its-kind, full-scale deployment for decarbonisation modelling at an airport.

• The model simulates the impact of installing PV solar panels.
• It tests the integration of new electric vehicle (EV) chargers.
• It models the electrification of heat by replacing gas boilers with heat pumps.

This IES decarbonisation modelling verified the airport's pathway. The simulations confirmed the potential for up to 63% CO2 savings against a 2019 baseline. This data provides the confidence needed for large-scale capital investments.

Broader Sustainability Roadmap

The net-zero emissions 2030 target covers the airport operator's own activities. This includes all Scope 1 and 2 emissions. Brussels Airport has been CO2-neutral since 2018 through offsetting. The new goal focuses on absolute emissions reduction.

Key Infrastructure Investments

Beyond the digital twin, Brussels Airport is making major infrastructure changes. The central heating plant is being replaced with a net-zero carbon system. This single project is projected to cut 70% of CO2 emissions.

The airport is also expanding its renewable energy production. A 65,000 m² solar panel installation is underway in the cargo zone. This will double the airport's total solar energy supply.

Industry Impact and Collaboration

This aggressive timeline positions Brussels Airport as a leader. It has achieved Level 4+ Transition of the Airport Carbon Accreditation programme. This makes it the highest accredited airport in Belgium.

This project demonstrates the authority of digital twin technology. It allows complex entities like airports to de-risk large sustainability investments. The technology helps create a clear Aviation sustainability roadmap. This model can be replicated by other airports globally. Other Stargate consortium members, including Athens and Budapest airports, are also using IES for digital twin development. This collaboration is crucial for accelerating greener aviation across Europe.
