The world economy continues to witness a steady rise in carbon emissions, which makes it challenging to fulfill the terms of the Paris agreement on reducing greenhouse gas emissions. In this context, countries worldwide enact environmental regulations to curtail environmental pollution to promote sustainable development. However, the importance of environmental regulations has not been fully validated in the previous literature. In addition, the concurrent roles of capital formation, green innovation, and renewability cannot be overlooked. Against this backdrop, this study selects data from G7 countries from 1994 to 2019 to explore the effect of environmental regulations, capital formation, green innovation, and renewable energy consumption on CO2 emissions. In order to achieve the above research objectives, we employ the Method of Moments Quantile Regression (MM-QR) for empirical analysis. The results reveal that capital formation significantly enhances environmental quality by reducing CO2 emissions across all quantiles (10th–90th). Environmental regulations show a significant and negative impact on CO2 emission mainly at the middle and higher emissions quantiles, while the effect is insignificant at lower quantiles (10th). Moreover, green innovation and renewable energy consumption mitigate CO2 emissions across all quantiles (10th–90th), while economic growth deteriorates environmental quality in G7 countries. The panel granger causality results indicate the unidirectional causality running from capital formation, environmental regulations, and renewable energy towards CO2 emissions, which implies that any policy related to these variables will Granger cause CO2 emissions but not the other way round. Based on the findings, important policy implications are proposed to promote sustainable development in G7 countries.

Based on a survey of the teaching staff in 20 Vocational College of Shandong Province, the present paper described the current research situation of vocational colleges in China with detailed figures and proposed strategies to strengthen the scientific research management of vocational colleges.

This study considers the dynamic pricing and green advertising incentive decisions in the O2O closed-loop supply chain. Through green advertising efforts, the manufacturer and the retailer push up the consumers’ environmental consciousness and the return rate of the end-of-use products. Based on the manufacture directing Stackelberg game theory, this research looks into three different green advertising decisions (noncooperative, unilateral cooperative, and bilateral cooperative) under wholesale price contract, revenue-sharing contract, and financial support contract in the O2O CLSC. The results show that the bilateral cooperative incentive strategy always makes both the manufacturer and the retailer invest more in green advertising efforts and increase profits. Without affecting sales, implementing the bilateral cooperative incentive mechanism under the financial support contract is the best strategy to mitigate channel conflict, promote Pareto improvement, and ultimately achieve sustainable development goals.
