This is the pre-registered protocol for a sole-author scoping review mapping empirical research on energy poverty published during the green transition era (2019–2025). The review follows the Arksey and O'Malley (2005) framework, refined by Levac et al. (2010), operationalized through JBI methodology (Peters et al., 2020), and reported per PRISMA-ScR (Tricco et al., 2018) standards. The review will map:- Energy poverty (EP) measurement metrics (10%-rule, LIHC, 2M, M/2, multidimensional indices, hidden EP)- Five categories of green transition variables: renewable energy, carbon pricing, transition policies, demand-side technology, and transition-linked price shocks- Policy response framings and their co-variation with measurement choices Three research questions guide the scoping review:- RQ1: Mapping the literature (measurement metrics, methodological approaches, geographic contexts, green transition variables)- RQ2: Identifying gaps (under-represented populations, regions, variables, or designs)- RQ3: Charting the conceptual landscape (policy response framing co-varying with measurement choices) Data sources: Scopus + Web of Science Core Collection. Time window: January 2019 – December 2025. Pilot search executed on 22 May 2026 yielded 1,803 (Scopus) + 2,911 (WoS) records, with approximately 2,967 estimated unique records after deduplication. This protocol is registered prior to study selection in compliance with PRISMA-ScR transparency standards. All search outputs, screening decisions, charting forms, and decision logs will be archived on this Zenodo deposit upon completion.
