How Will Siemens, Airbus & Capgemini Cut Aviation Emissions?

When three companies the size of Siemens, Airbus and Capgemini join forces, growth follows.

But not this time. The three are combining with a different aim – to hasten the decline of greenhouse gas emissions (which will, of course, drive business growth).

The strategic contract will be led by Siemens’ Buildings business and supported by Capgemini, combining the companies’ expertise in sustainability and digitalisation to ensure the success and timely delivery of the project.

Site-specific solutions

It is part of Airbus’ programme to reduce its operational environmental footprint.

The programme targets an energy consumption cut of 20% and a Scope 1 and 2 stationary emissions cut by 85% by 2030.

As part of the framework agreement, Siemens will deploy its scalable decarbonisation solutions, tailored to the selected sites, to support Airbus in reaching the target of 80 kt CO2e abated annually from 2030.

The replicable solutions include renewable energy integration, smart energy management and low-carbon heat systems, delivered in collaboration with Capgemini.

Scalable solutions for measurable impact

Siemens will evaluate the sites and create and implement an overall decarbonisation masterplan, including solutions to reduce energy demand and carbon emissions.

To accelerate the selection of the measures, energy system twins will simulate and help determine the best decarbonisation roadmaps for the sites.

The key elements include decarbonisation of heat production via:

• Heat pumps
• Energy efficiency upgrades
• Smart metering systems
• On-site smart integration of renewable energy
• Smart energy management systems to monitor, control and optimise usage across the sites.

Mutual trust and shared ambition

Capgemini has been appointed by Siemens to complete first phase consulting activities, governance definition and support for project management and planning.

It also brings its expertise in the digitalisation and automation of the energy monitoring and measurement systems.

Susanne Seitz, CEO of Buildings at Siemens Smart Infrastructure, says: “Our collaboration with Airbus is built on years of mutual trust and shared ambition.

“It highlights Siemens’ capability to deliver smart and scalable technologies and services to reduce the carbon footprint of Airbus.”

The path to aviation decarbonisation

Florent Massou dit Labaquere, EVP Operations of Airbus Commercial Aircraft, says the agreement will “keep Airbus on the right path”.

He adds: “We’re proud to be taking this important step toward making our operations more energy-efficient and future-ready.

“Collaborating with trusted partners is key in building a more resilient industrial footprint.

“The site-specific expertise from our Airbus colleagues in the UK and the US combined with Siemens’ technical know-how will keep us on the path toward meeting our energy use and emission reduction targets.”

Susanne adds: “At Siemens, we’re committed to making the energy transition not only sustainable, but also achievable and scalable, so that Airbus and other industrial leaders can confront climate challenges while boosting operational resilience and long-term competitiveness.”

Roadmap to 2030

The initial phase began in summer 2025 with the development of decarbonisation roadmaps for each site.

Engineering studies will guide the implementation, with infrastructure rollout starting in 2026.

Siemens can also operate and maintain the new infrastructure, ensuring long-term efficiency and resilience.

Siemens and Airbus have been working together for more than half a century.

Key initiatives have included factory automation, industrial software, safety and security, and building automation technology.
