Here is a number that should be in every ESG report but rarely is: 80% of a server’s carbon footprint is created before it is powered on.
Not during operation. Not from the electricity it consumes over its lifetime. Before it even reaches your data center.
Most sustainability reporting in the datacenter industry focuses on operational emissions. Energy efficiency ratios. Renewable energy sourcing. Cooling optimization. These matter. But they account for roughly 20% of the total carbon impact of your hardware.
The other 80% is embodied carbon. And almost nobody is measuring it.
What is embodied carbon?
Embodied carbon is the sum of all emissions generated during the manufacturing lifecycle of a piece of hardware. It includes:
Raw material extraction. Mining the metals, rare earths, and minerals that go into processors, memory modules, and circuit boards. Component fabrication. The energy-intensive processes of semiconductor manufacturing, PCB assembly, and system integration. Global shipping. Moving components and finished systems across continents, often multiple times before final assembly.
By the time a new server arrives at your loading dock, it carries a carbon debt that no amount of renewable energy can offset. The emissions already happened.
The circular alternative
Extending the lifecycle of existing hardware eliminates new embodied carbon entirely. No new mining. No new manufacturing. No new transcontinental shipping.
RackRenew is extending the life of hardware designed by hyperscalers to run under the demanding conditions of the busiest hyperscale datacenters. We certify all components to provide servers that you can expect to last as long as a new purchase from other vendors. And we stand behind this with our warranty
The result: equivalent compute performance with up to 80% less carbon impact per unit.
Origin Mark: proof, not promises
Sustainability claims without verification are just marketing. That is why RackRenew developed Origin Mark, a hardware traceability platform that gives every piece of remanufactured equipment a verifiable, audit-ready identity.
Origin Mark documents the full journey of each unit: where it was sourced, how it was tested, what certifications it carries, and what carbon reduction it represents compared to a new equivalent.
The regulatory reality
The EU Corporate Sustainability Reporting Directive (CSRD) is changing what companies are required to disclose about their environmental impact. Scope 3 emissions, which include the embodied carbon of purchased goods and services, are becoming mandatory reporting territory for large enterprises.
That means your data center hardware procurement decisions will show up in your sustainability reports. The question is whether they show up as a problem or a solution.
Remanufactured Open Compute Project (OCP) hardware, with full traceability through Origin Mark, turns your hardware refresh from a carbon liability into a documented sustainability win.
What this means for your infrastructure roadmap
If you are a sustainability officer, you need audit-ready proof of carbon reduction across your supply chain. If you are a CTO, you need hardware that performs at enterprise grade without the budget of buying new. If you are a CFO, you need both.
Remanufactured OCP hardware is the intersection where all three requirements meet.
👉🏼 We are heading to CloudFest 2026 to have this conversation in person. Visit us at our booth Z08 to see the hardware up close, walk through the benchmark data, and discuss how circular infrastructure fits your sustainability roadmap.
CloudFest 2026. March 23-26. Europa-Park, Germany.
