Transformation of Data Centers: Meta's Switch from Steel to Mass Timber for Eco-Friendly Operations
Meta Embraces Mass Timber for Sustainable Data Center Construction
Meta, the tech giant formerly known as Facebook, is making significant strides in reducing carbon emissions and promoting sustainability by incorporating mass timber into its data center construction projects.
Lower Embodied Carbon and Construction Emissions
By opting for mass timber, a wood-based engineered product that stores carbon captured by trees during growth, Meta is significantly cutting the carbon footprint of its construction materials. Compared to traditional concrete and steel, mass timber reduces embodied carbon by about 41% [1][2][3][4][5].
The prefabrication of mass timber components off-site also minimizes steel welding and concrete pouring on-site, reducing emissions generated during construction and shortening project timelines by several weeks [1][2][3][5].
Less Concrete and Greater Strength
Because mass timber is lighter than steel, data centers require substantially smaller concrete foundations—up to half the volume in some cases—further reducing carbon emissions and costs associated with concrete pouring [1][3][5]. Engineered mass timber products have a higher strength-to-weight ratio than steel and develop a protective char layer when exposed to fire, making them reliable, safe substitutes in data center settings where structural integrity and fire safety are critical [1][3][4][5].
Supporting Sustainability Targets
Incorporating mass timber helps companies like Meta aim for net zero carbon emissions across their entire value chain by 2030. By cutting embodied carbon and reducing construction emissions, mass timber contributes primarily to lowering Scope 3 emissions related to materials and construction activities [1][4][5].
Biophilic Design Benefits and Scalability
Exposed mass timber in workspaces connects occupants to nature, which can reduce stress, improve morale, increase productivity, and foster wellness for staff working in these facilities [1][3]. Initial pilot projects with administrative buildings are expanding to other structures including warehouses and critical data halls, indicating mass timber’s feasibility for larger-scale data center infrastructure [3][4].
Circularity in Data Center Hardware
Meta is also embedding circularity into its data center hardware lifecycle. For instance, the company is using lithium-ion battery backup units (BBUs) instead of older lead-acid versions [6].
Ongoing Projects and Partnerships
Meta has multiple ongoing mass timber projects in Cheyenne, Wyoming, and Montgomery, Alabama [7]. The company has also partnered with BTG Pactual Timberland Investment Group in Brazil for a major reforestation effort, delivering up to 3.9 million carbon removal credits through 2038 [8].
Meta's first mass timber office building was completed in Aiken, South Carolina [9]. In 2023, Meta started using mass timber at its data center campuses [10].
In conclusion, the adoption of mass timber offers a promising, sustainable alternative to steel and concrete in data center construction. By reducing carbon emissions significantly, accelerating construction, and promoting occupant well-being, mass timber supports ambitious corporate sustainability and net zero goals [1][3][4][5].
