ZUG, Switzerland, Oct 31, 2025 – Siemens and Airbus signed a contract to reduce emissions at Airbus industrial sites in the U.S. and U.K. The program targets lower CO2 and energy use across operations.
Siemens will deploy decarbonization solutions to to help abate 80 kt of CO2e per year starting in 2030. Siemens’ Buildings unit will lead delivery, with Capgemini supporting sustainability and digital systems.
Decarbonization at Scale: Scalable Solutions for Measurable Impact
Siemens will assess each site and develop a decarbonization master plan. The plan will guide implementation of measures to reduce energy demand and carbon emissions. Energy system twins will simulate site operations to help select the actions and sequence the roadmap. Key measures include heat-pump deployment, energy-efficiency upgrades, smart metering, on-site integration of renewable energy, and smart energy management systems for monitoring and control. These measures are designed help Airbus reduce energy consumption by 20% and scope 1 and 2 greenhouse-gas emissions by 85% by 2030, compared with 2015 levels.
Capgemini, appointed by Siemens, will complete first-phase consulting, define governance, and support project management and planning. It will also support digitalization and automation of energy monitoring and measurement systems.
“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. 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,” said Susanne Seitz, CEO of buildings at Siemens Smart Infrastructure.
“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 U.K. and the U.S. combined with Siemens’ technical know-how will keep us on the path toward meeting our energy use and emission reduction targets,” said Florent Massou dit Labaquere, EVP operations of Airbus commercial aircraft.
Roadmap to 2030
The initial phase began in summer 2025 with the development of decarbonization roadmaps for each site. Engineering studies will guide the implementation, with infrastructure rollout starting in 2026.
