Introducing a new measure of energy transition: Green quality of energy mix and its impact on CO2 emissions
为OECD国家构建了能源结构绿色质量指标，并基于1970-2021年面板数据发现该指标与二氧化碳排放负相关，而人均收入、制度质量和技术则增加排放。
This paper introduces a novel measure of the energy transition, i.e., the green quality of energy mix (GREENQ) across the Organisation for Economic Co-operation and Development (OECD) countries. Then, the paper examines the impact of the GREENQ on CO2 emissions in the panel dataset of 36 OECD countries from 1970 to 2021. The explanatory variables include per capita income, institutional quality and technology. Long-run panel data estimations indicate that per capita income, institutional quality and technology increase CO2 emissions. The novel evidence is that the GREENQ is negatively related to the level of CO2 emissions. These findings are robust to employ different panel data estimation techniques. Potential policy implications are also discussed.
