Alexis Bateman: Where Next for Sustainable AWS Data Centres?

Amazon Web Services (AWS) has promoted Dr Alexis Bateman to Head of Global Sustainability, expanding her remit at a time when environmental performance is increasingly tied to the design and operation of hyperscale data centres.

Alexis joined AWS in 2021 as a Principal Product Manager before moving into the role of Head of Sustainability. Her new position widens that responsibility across AWS’s global operations as the company scales its cloud infrastructure while pursuing net zero carbon and water positivity targets.

The appointment signals how deeply sustainability considerations are now embedded in AWS’s infrastructure strategy. With millions of servers operating across regions, decisions around energy sourcing, cooling design and supply chain emissions have become board-level priorities.

Alexis brings a background that blends academic research with industrial delivery. She has studied and researched sustainability science at institutions – including MIT and the University of California – and previously held roles at Nike and Open Supply Hub. That combination of theory and practice is increasingly relevant as data centres move from efficiency gains to system-wide decarbonisation.

Sustainability as a data centre strategy

AWS is pursuing a series of public environmental commitments that directly affect its data centre portfolio. These include achieving net zero carbon across operations by 2040 and becoming water positive by 2030. As the cloud business continues to expand, meeting those targets depends on how facilities are designed, built and operated.

The company’s global data centre footprint makes energy efficiency and environmental impact unavoidable concerns. AWS infrastructure is reported to be up to 4.1 times more energy efficient than typical on-premises data centres, a figure that underpins its sustainability case to enterprise customers migrating workloads to the cloud.

For hyperscale operators, efficiency gains are no longer limited to server utilisation. They extend to power distribution, cooling systems, materials selection and site location. Sustainability leadership therefore plays a role not only in reporting but also in shaping capital investment and operational standards across regions.

Academic roots in supply chain sustainability

Before joining AWS, Alexis built a reputation in supply chain sustainability through her work at MIT, where she remains a visiting lecturer. As Director of MIT Sustainable Supply Chains, she developed programmes that reached hundreds of thousands of professionals globally through the MITx MicroMasters initiative.

Her research examined how organisations measure and act on sustainability goals, with a particular focus on transparency and accountability. She led the annual State of Supply Chain Sustainability Report at MIT, which found that nearly half of supply chain professionals were directly involved in sustainability decision-making.

That experience is relevant to data centres, where Scope 3 emissions linked to construction materials, equipment manufacturing and logistics can outweigh operational emissions. Addressing those impacts requires visibility across complex global supply chains rather than isolated efficiency projects.

Alexis has published research in outlets including the Harvard Business Review, the Wall Street Journal and Sloan Management Review and has contributed to the Handbook of Business and Climate Change. Her work consistently highlights transparency as a prerequisite for credible climate targets.

Operational focus for AWS data centres

In her expanded role, Alexis is expected to continue prioritising carbon accounting tools that translate sustainability goals into operational insight. AWS’s Customer Carbon Footprint Tool allows customers to track historical emissions and estimate avoided emissions by running workloads on AWS infrastructure.

For data centre users, this level of granularity supports compliance reporting and informs decisions about workload placement and architecture. It also places pressure on operators to provide accurate and timely environmental data at facility level.

Water stewardship is another key area. AWS has committed to returning more water to communities than it uses in direct operations by 2030 and has already improved water usage effectiveness by 40% since 2021. For data centres, this involves site-specific water strategies, alternative cooling approaches and engagement with local stakeholders.

Scope 3 emissions remain the largest component of AWS’s overall carbon footprint. Addressing them will require continued collaboration with equipment suppliers, construction partners and energy providers as AWS expands its global data centre estate.
