Meta Switching Traditional Materials for Wood in Data Centers to Lower Carbon Emissions
Meta and Microsoft are leading the charge in the data center industry by incorporating mass timber into their construction projects. This engineered wood product, known for its strength, durability, and lower embodied carbon, is being used to significantly reduce the carbon footprint associated with traditional building materials like steel and concrete.
Meta's pilot projects demonstrate that using mass timber can reduce embodied carbon emissions by up to 41% compared to conventional materials. The company sources wood for its mass timber projects from forests managed for long-term ecological and social health, as verified by third-party audits. This commitment to sustainability ensures a long-term, sustainable source of timber for mass timber and other timber markets.
The use of mass timber offers several key benefits in data center construction:
- Lower embodied carbon: Replacing steel and concrete with mass timber reduces emissions throughout a building material’s lifecycle.
- Carbon storage: Wood stores carbon absorbed during tree growth, providing a net carbon benefit.
- Prefabrication advantages: Mass timber is largely prefabricated, which accelerates construction schedules, reduces on-site emissions, and cuts logistics complexity.
- Foundation and material efficiency: The lighter weight of mass timber reduces foundation concrete requirements by as much as half.
- Strength and durability: Engineered mass timber has a high strength-to-weight ratio, suitable for industrial applications.
- Wellness benefits: Exposed mass timber fosters biophilic design elements in workspaces, improving staff well-being, reducing stress, and increasing productivity.
Meta has constructed its first mass timber administrative building at its Aiken, South Carolina data center and plans further mass timber buildings in Wyoming and Alabama. The company aims to expand this approach to warehouses and core data halls. Microsoft, too, has adopted cross-laminated timber (CLT) as part of a hybrid construction approach to lower emissions in its data centers.
This shift toward sustainable timber construction is part of Meta's broader efforts to address the challenges of reaching its net zero emissions target while building out infrastructure to accommodate the rapid growth of AI. The company's net zero program aims to support not only emissions reduction but also the thriving of communities, forests, and watersheds.
In addition, Meta prioritizes suppliers who practice climate smart forestry and uses reclaimed wood in its mass timber projects where it is structurally viable. This approach aligns with Meta's mission to support projects through its net zero efforts that benefit both people and nature.
The use of wood products in data center construction by companies like Meta and Microsoft is a response to addressing their carbon footprints. Steel manufacturing and cement production account for approximately 7% and 8%, respectively, of global carbon emissions, according to the World Economic Forum. By embracing mass timber, these tech giants are contributing to a broader trend in the industry that prioritizes sustainability and carbon reduction.
Exposure to wood elements in workspaces, as seen in mass timber buildings, can enhance occupants' well-being by connecting them to nature. This biophilic design element is not only beneficial for employees but also aligns with Meta's focus on creating workspaces that foster productivity and innovation.
