Definition

Distributional impact refers to how the effects of a policy or measure are spread across different groups in society — typically analysed by income decile, region, gender or vulnerability. Distributional impact assessment, as used in the EU's budgetary and European Semester processes, quantifies effects of policy measures on household incomes, including for the most vulnerable, using tools such as the EUROMOD microsimulation model, and is recommended for green, digital and demographic transition policies.

Overview

What it means

Asking not only whether a policy works, but who pays and who benefits — the equity dimension of sustainability transitions.

How it is used

Carbon-pricing, energy-subsidy reform and climate packages are routinely assessed for distributional impacts; results shape compensation design (e. g. lump-sum rebates).

Why it matters

Regressive policy design can make climate action politically unsustainable; distributional analysis is the technical foundation of a just transition.
