Meta’s Sustainable Design Strategy for Data Centres

Meta’s approach to sustainable design in data centres reflects a shift in how hyperscale infrastructure is conceived, built and operated. Rather than treating sustainability as a compliance layer, the company integrates it into hardware engineering, construction methods and supplier engagement.

At the core of this strategy is Meta’s “Design for Sustainability” framework, which sets out technical principles to reduce emissions across IT hardware lifecycles. This includes modular design, reuse of components, dematerialisation and the use of lower-carbon materials. These interventions target Scope 3 emissions, which remain the most complex challenge for data centre operators due to their link to manufacturing and supply chains.

In its 2025 engineering guidance, the company explained: “Sustainable hardware design requires collaboration between hardware designers, engineers and sustainability experts to meet performance requirements while limiting environmental impact”. 

This reflects a systems-level view, where efficiency gains are achieved not only through energy use but through material selection and lifecycle management.

Circular hardware and modular innovation

A defining feature of Meta’s sustainable design strategy is circularity. Modular rack architectures such as Open Rack v3 enable components to be replaced, upgraded or reused without discarding entire systems. This reduces both embodied carbon and electronic waste.

Retrofitting existing infrastructure is another key lever. By adapting racks for higher-density workloads, Meta reduces the need for new manufacturing while accelerating deployment timelines. The company reports that reuse strategies can lower costs, cut e-waste and improve operational efficiency.

Material choices further reinforce this approach. Meta now requires a minimum of 20% recycled steel in racks and mandates that heat sinks are made entirely from recycled aluminium or copper. These requirements directly reduce the energy intensity associated with raw material extraction and processing.

The company also works closely with suppliers through its net zero engagement programme. By 2024, this initiative had expanded to 183 suppliers, representing more than half of Meta’s supplier-related emissions, with 48% already setting science-aligned targets.

Low-carbon construction and materials

Sustainable design extends beyond hardware into the physical construction of data centres. Meta is piloting low-carbon concrete, using alternatives such as fly ash and slag to reduce embodied emissions. The company is also investing in AI-assisted methods to optimise concrete formulations, improving both performance and carbon outcomes.

In 2025, Meta introduced mass timber in data centre campus construction, starting with an administration building in South Carolina. This material substitution reduces reliance on emissions-intensive steel while maintaining structural performance.

Back-up power systems are also evolving. The adoption of hydrotreated vegetable oil (HVO) as a diesel alternative has expanded from its Clonee facility in Ireland to multiple North American sites, reducing operational emissions associated with standby generation.

These initiatives demonstrate how sustainable design principles are applied consistently across the full lifecycle of data centre assets, from groundworks to operations.

Energy efficiency and operational performance

Meta’s operational metrics reinforce its design-led approach. The company reports that 100% of its owned and operated data centres are matched with renewable energy, while all facilities achieve LEED Gold certification or higher.

Efficiency improvements are also evident in infrastructure design. Next-generation data centres are engineered to deliver equivalent compute capacity using less physical space, reducing both construction impact and resource consumption.

Cooling innovations play a role here. Liquid cooling technologies, for example, can be up to 17% more carbon-efficient than traditional air cooling in certain environments, supporting higher-density AI workloads while lowering emissions.

As Meta notes, “design improvements and site-specific operational solutions” are central to balancing performance demands with sustainability goals, particularly as AI-driven compute requirements grow.

Designing for net zero

Meta’s sustainable design strategy is aligned with its target to reach net zero emissions across its value chain by 2030. Achieving this requires continued focus on upstream emissions, particularly those embedded in hardware and construction.

Extending equipment lifecycles is a critical factor. By improving reliability and reusing components such as memory modules, Meta reduces the volume of new hardware required. This approach not only cuts emissions but also addresses supply chain pressures.

Dematerialisation further supports this goal by removing unnecessary components and consolidating infrastructure. Fewer materials translate directly into lower carbon footprints and reduced resource consumption.

The company summarises its direction clearly: “Integrating modularity, reuse, retrofitting and greener materials allows us to significantly reduce the carbon footprint of our data centre infrastructure”. This reflects a pragmatic, engineering-led pathway to sustainability, grounded in measurable design choices.
