The discourse on cloud sustainability has been dominated by operational carbon—the emissions associated with electricity consumption during workload execution. This focus, while important, obscures a critical and growing dimension of cloud environmental impact: embodied carbon, the emissions released during the manufacturing, transportation, and disposal of the physical infrastructure that underpins cloud services. As renewable energy adoption accelerates and data center power usage effectiveness (PUE) approaches theoretical limits, embodied carbon is emerging as the dominant and most intractable component of cloud carbon footprints. This paper presents a lifecycle-aware framework for cloud-native infrastructure engineering that treats embodied carbon as a first-class constraint alongside performance, cost, and reliability. The proposed framework integrates: (1) a carbon depreciation model that incentivizes extended hardware lifetimes by allocating embodied carbon costs to newly provisioned servers; (2) a carbon-aware infrastructure-as-code (IaC) analysis engine that estimates embodied carbon impacts during the design phase; (3) a heterogeneous compute scheduling layer that matches workload characteristics to hardware generations with different embodied carbon profiles; and (4) a carbon-aware CI/CD integration that incorporates embodied carbon thresholds into deployment decisions. Drawing on empirical evidence from hyperscale deployments and lifecycle assessment studies, the framework demonstrates that extending server lifetimes from three to five years can reduce net cloud emissions by 28–57%, while GreenSKU-style hardware reuse strategies can achieve 8% net emissions reductions in production environments. The paper establishes that embodied carbon must be treated not as an externality but as a fundamental architectural constraint, and that doing so requires rethinking foundational assumptions about hardware refresh cycles, performance homogeneity, and the very meaning of “efficiency” in cloud operations.
