The Digital Decoupling Paradox: When More Bits Mean Fewer Emissions—Until They Don’t

Haller et al. (2023) suggest digitalization correlates with declining GHG in Europe, but their analysis flags measurement gaps. This project addresses those gaps by building a new digitalization dataset distinguishing productivity-enhancing digitization (ERP adoption, e-invoicing, robotic process automation) from compute intensity (data center capacity, AI workload proxies), and then interacting both with local energy mixes and renewable penetration (Ahmed & Elfaki, 2023). The theory is that digitization improves energy and material efficiency (lowering emissions), but rising compute intensity raises electricity demand that curbs or reverses gains when powered by fossil-heavy grids—a nonlinearity hidden in coarse indicators. Identification leverages quasi-experiments: openings of hyperscale data centers, submarine cable landings, and cloud-region rollouts; the empirical strategy uses CS-ARDL and Dumitrescu–Hurlin tests to capture heterogeneous long-run dynamics, echoing Haller et al.’s methods but with richer measures. The novelty is to turn “digitalization” from a monolith into two interacting forces with a policy-relevant threshold: green gains accrue only if compute growth is sequenced with renewable deployment. This reframes digital policy as a complement to, not a substitute for, energy transition.
