Currently, Pakistan is in a stage of urbanization and industrialization, raising its energy demand and supply and carbon dioxide emissions (CO2Es) due to the excessive use of fossil fuels. In meeting future demand and supply predictions, much emphasis should be given to both energy consumption and the level of inter-factor and inter-fuel substitution possibilities. Specifically, future outcomes for energy demand are more valid when production models contemplate substitution elasticity occurring during the period. To analyze the potential for little reliance on fossil fuels and diminish CO2Es, the present research has examined the potential for the substitution of energy and non-energy factors (i.e., natural gas, electricity, petroleum, labor, and capital) by using translog productions function over the period between 1986–2019. The ridge regression method is applied to evade the multicollinearity issue in the data. The model analyzes the output elasticity, substitution elasticity, technical progress, and carbon emission scenarios. The results show that the output elasticities are growing, presenting that the contribution of all factors adds to economic growth. The inputs between capital-petroleum, capital-electricity, labor-electricity, capital-natural gas, and natural gas-electricity are extreme substitutes. These substitutes are increasing capital growth and production sizes. The relative difference in technical progress shows a small positive change between 3–7% with convergence evident. Lastly, the investment scenarios under 5% and 10% investment in petroleum reduction are evidence that the CO2Es would reduce by 7.5 Mt and 10.43 Mt under scenario 1 and 7.0 Mt and 10.9 Mt under scenario 2. The results have broader suggestions for energy-conserving policies, particularly under the China–Pakistan Economic Corridor. [ABSTRACT FROM AUTHOR]

Digital development is critical for achieving coordinated regional economic growth, energy conservation, and emissions reduction, which makes it a viable method for achieving carbon neutrality and peaks. This study investigates the impact of the digital economy on urban total factor productivity and carbon emissions, as well as its mechanism, from 2011 to 2019 by developing a digital economy evaluation index system. We find that the growth of the digital economy can increase urban total factor productivity while lowering carbon emissions and also has a significant spatial spillover effect on regional economic growth, energy conservation, and emissions reduction. The main influencing mechanism is that the digital economy accelerates marketization by encouraging industrial structure upgrades and technological progress, which results in higher total factor productivity and lower energy consumption. In terms of the spatial distribution, the digital economy promotes total factor productivity more in the central and western regions and large cities and promotes carbon emission reduction less in the eastern regions and smaller cities. The findings extend the benefits of the digital economy beyond economic and social welfare benefits and serve as a model for achieving a win–win situation in terms of both economic growth and carbon emissions reduction.

Renewable energy attracts attentions by removing the harmful effects of fossil fuels and protecting the environment. The focus of this study is to investigate GDP per capita, carbon dioxide emissions per capita, technological innovation and trade as the determinants of renewable energy production for the selected Latin American countries during the 1991–2014 period. Technological innovation factor is rarely investigated as one of the determinants of renewable energy. The country group includes Argentina, Brazil, Mexico, Colombia, Chile and Guatemala. Empirical results are obtained by applying panel estimation methods. Cointegration relationship among the analyzed variables is confirmed by Pedroni and Westerlund panel cointegration tests. According to the empirical analysis, GDP per capita, technological innovation and trade have positive and statistically significant impact on renewable energy production per capita. On the other hand, it is found that carbon dioxide emissions and renewable energy production are negatively associated. In addition, the elasticity estimates with respect to technological innovation and trade are found as close to each other. The policy implications of the empirical findings are argued as well. [Display omitted] • The drivers of renewable energy generation are analyzed by panel data techniques. • A 1% rise in output is found to increase renewable energy production by 0.26%. • The effects of technological innovation and trade are estimated as very close. • The elasticity estimate with respect to CO2 emission is found as −0.196.

Bangladesh has traditionally relied on fossil fuels for meeting its energy demand whereby this major South Asian economy has not been able to safeguard its environment from greenhouse gas emission-related adversities. Moreover, by ratifying several international environmental agreements, especially the Paris Accord and the Sustainable Development Goals, the government of Bangladesh has expressed its solidarity in abating greenhouse gas emissions through the deployment of relevant environmental policies. Hence, this study assesses the impacts of petroleum consumption, economic growth, and technological innovation on carbon emissions in Bangladesh using quarterly frequency data from 1972Q1 to 2020Q4. Overall, apart from confirming the cointegrating relationships among the variables, the regression findings reveal that higher petroleum consumption and economic growth stimulate environmental degradation by boosting carbon dioxide emissions while technological innovation reinstates environmental well-being by curbing the Bangladesh's emission figures. Additionally, technological innovation is seen to moderate the relationship between petroleum consumption and carbon emissions by jointly reducing the emissions with petroleum consumption. Lastly, the causality analysis shows that petroleum consumption, economic growth, and technological innovation causally influence carbon emissions. Based on these key findings, it is recommended that Bangladesh mitigates its petroleum dependency, blends environmental objectives into its economic growth policies, and develops its technological stock. • Determinants of environmental well-being in Bangladesh are analyzed. • Petroleum consumption and economic growth boost carbon emissions. • Technological innovation reduce carbon emissions. • Technological innovation moderates the petroleum consumption-carbon emissions nexus. • Petroleum consumption and technological innovation jointly reduce carbon emissions.

Energy and green innovation are important to a country's economic progress, but the externalities of increased pollution as a result of a rise in energy used and economic growth must not be overlooked. Within the Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) framework, this study aims to check empirically the effect of environment-related technologies (ERT), coal consumption (CC), economic growth (EG), and population density (PD) on the consumption-based CO 2 emissions (CCO 2e) in the BRICS (i.e., Brazil, Russia, India, China, & South Africa), as with fast economic progress BRICS is facing problems of CO 2 emission. The econometric techniques of the cross-sectional dependence test, slope heterogeneity test, and second-generation panel unit root test were used to check the nature of the data. The available balance data over the period 1985–2018 were analyzed via Driscoll and Kraay and a dynamic common correlated effect mean group (DCCEMG). Long-term empirical findings show that ERT has a negative impact on the CCO 2e , while per capita GDP and CC have a positive impact on CCO 2e. Empirical evidence recommends that ERT is important for BRICS countries' long-term sustainability. It is suggested that policymakers should encourage ERT that help in curbing their CO 2 emanations.

In achieving the "double carbon" target, the emission trading system (ETS), as a key market-based emission reduction mechanism, assumes the responsibility of addressing climate change and implementing reform. Most studies focus only on the emission reduction effects of green policy, but weighing the relationship between emission reduction and development is a practical dilemma to be faced. Taking China's pilot ETS as an example, this problem was analyzed using the synthetic control method, and the specific impact channels are discussed. It was found that: (1) Carbon emissions and carbon emission intensity in the pilot ETS areas of Tianjin, Hubei and Chongqing decreased significantly, and economic growth has progressed to a certain extent. Robustness tests basically verified the effectiveness of the policy implementation. (2) The pilot ETS mainly has an impact through the transformation and upgrading, and technological innovation channels, promoting significant improvements in energy structure, industrial structure, energy efficiency and the number of patent applications. This study releases a positive signal for the compatibility of emission reduction and economic development goals at the national level for China's pilot ETS. • The pilot ETS significantly reduced carbon emissions and carbon emission intensity. • The pilot ETS promoted economic growth to some extent. • Transformation and upgrading, and technological innovation are the influencing channel. • The SCM method can synthesize the "ideal" control unit to evaluate the policy effects.
