Countries differ in their energy infrastructures, economic structures, and socioeconomic contexts, resulting in uneven vulnerability to the energy transition. Advancing a just global transition requires that the most vulnerable are not left behind and that all countries make measurable progress. To support this effort, we introduce the Energy Transition Vulnerability Index (ETVI), a global metric assessing national-level vulnerability. The framework draws on the Vulnerability Scoping Diagram and evaluates vulnerability across three dimensions-exposure, sensitivity, and adaptive capacity-in accordance with the Intergovernmental Panel on Climate Change (IPCC) definition. The dataset provides ETVI scores and sub-indices for 142 countries and regions from 2000 to 2023. Developed using a consistent methodology, the spatiotemporal dataset supports both cross-country comparison and within-country tracking over time, and serves as a foundation for further research. Insights derived from such research can inform the design of inclusive energy transition strategies and support international policy coordination.

The COP28 agreement signals “beginning of the end” of the fossil fuel era, calling on countries to contribute to global efforts to transition away from fossil fuels in energy systems in a just, orderly and equitable manner. While a quantitative assessment of country's vulnerability in energy transition is a prerequisite for national and international policy makers to ensure a just and inclusive transition, it is notably absent in the existing research. Here, we develop a conceptual framework based on the vulnerability scoping diagram (VSD) method to assess differences in energy transition vulnerability across countries, with a specific focus on the challenges associated with transitioning away from fossil fuels. The resulting energy transition vulnerability index (ETVI) scores reveal that countries in the Global South generally exhibit higher vulnerability in their energy transition compared to those in the Global North, and this gap has widened over the past decade. Moreover, the COVID-19 pandemic has disrupted the decade-long trend of continuous decline in global energy transition vulnerability. This study also provides two important applications of ETVI scores, aligning them with major global sustainable development agenda. Firstly, we identify substantial differences in the dynamics of transition vulnerability across seven major party groups in the international climate change negotiations and distinguish four energy transition statuses in relation to achieving global climate goals: Stressful, Leapfrog, Potential Challenges, and Less Painful. Secondly, we demonstrate crucial synergies between energy transition resilience and the 2030 United Nations Sustainable Development Goals (SDGs).

Increasing household energy consumption, mainly due to consumption upgrading, will create tough challenges for China if that country is to achieve peak carbon emissions in 2030 and carbon neutrality in 2060. However, this critical issue has not been explored comprehensively in the literature. Using China Family Panel Studies data and the distribution dynamics approach, this article is the first study to examine the relationship between quality of life (QOL) (proxied by consumption upgrading) and relative household energy consumption (RHEC). The results show that convergence clubs exist in all QOL groups for the RHEC, but they are more evident in the groups with lower middle and low QOL. This is encouraging because they suggest that an improvement in QOL does not necessarily lead to a higher level of energy consumption. The dataset was then divided into rural‐urban and regional subgroups to further explore the impacts of these different characteristics on energy consumption. Significant disparities are found among the same QOL groups between urban and rural households and among different regions. The results derived from this study lead to pragmatic policy suggestions in areas including energy saving, emissions reduction, and particularly alleviation of inequality.
