Siemens and
Airbus have signed a new strategic contract aimed at accelerating the decarbonisation of Airbus’ major industrial sites in Broughton, Filton and Stevenage, as well as one site in the USA. The agreement marks a significant milestone in Airbus’ broader programme to reduce its operational environmental footprint, with a focus on cutting CO
2 emissions and energy consumption.
Under the framework agreement, Siemens will deploy its scalable decarbonisation solutions tailored to each site, with the goal of abating 80,000 tonnes of CO
2 equivalent annually from 2030. The project will be led by Siemens’ Smart Infrastructure Buildings business and supported by
Capgemini, combining expertise in sustainability and digitalisation.
Siemens UK & Ireland’s CEO Carl Ennis said: “Decarbonising industry cannot be done alone. It demands the right partnerships, the right technology, and the resolve to act. Our work with Airbus shows how industry leaders can unlock meaningful emissions reductions through digitalisation, smart infrastructure, and low-carbon energy systems. As one of the world’s most advanced engineering economies, the UK has both the opportunity and the capability to lead the way to ‘net zero’ — and we are proud to be helping deliver that transformation with Airbus.”
Siemens will begin by evaluating each site and developing a comprehensive decarbonisation masterplan. This will include the use of Energy System Twins to simulate and determine the most effective roadmaps for reducing energy demand and emissions. Key technologies will include heat pumps for low-carbon heat production, energy efficiency upgrades, smart metering systems, on-site renewable energy integration, and smart energy management systems to monitor and optimise energy use. The measures are designed to help Airbus meet its targets of a 20% reduction in energy consumption and an 85% reduction in Scope 1 and 2 ‘greenhouse’ gas emissions by 2030, when compared to 2015 levels.
Capgemini has been appointed by Siemens to carry out initial consulting activities, define governance structures, and support project management and planning. The company will also contribute its expertise in digitalising and automating energy monitoring and measurement systems.
The first phase of the initiative began in the summer of 2025 with the development of decarbonisation roadmaps for each site. Engineering studies will guide the implementation, with infrastructure rollout scheduled to begin in 2026. Siemens will also be responsible for operating and maintaining the new infrastructure to ensure long-term efficiency and resilience.
Siemens and Airbus have worked together for more than 50 years, with previous collaborations spanning factory automation, industrial software, safety and security, and building automation. This latest agreement builds on that legacy, supporting Airbus’ sustainability ambitions and its commitment to reducing its environmental impact.
