“…Khan et al [19] found that fossil fuels reduced and renewable energy improved the environmental quality in Europe. Moreover, bulk literature has suggested that the concept of a circular economy and green business practices would serve to promote eco-environmental performance [20][21][22][23][24][25][26].…”

Expansionary monetary and fiscal policies are necessary for economic and environmental development. The present research studies the impact of monetary policy and fiscal policy on Territory-Based CO2 (TBC) and Consumption-Based CO2 (CBC) emissions in Gulf Cooperation Council (GCC) economies from 1990–2019. The cointegration is corroborated through various tests, and long-term relationships are found in both TBC and CBC models. Government expenditures have long-term positive effects on both TBC and CBC emissions and short-term positive effects on TBC emissions in the region. Money supply negatively affects the TBC and CBC emissions in the long run and positively affects TBC and CBC emissions in the short run. Hence, monetary policy needs a long time to have positive ecological effects in the GCC region. Moreover, fiscal policy in both the long and short run and monetary policy in the short run have scale effects in GCC economies. Therefore, we recommend reducing fiscal measures and encouraging monetary policy in the long run to have positive environmental outcomes in the region.

“…Notably, the Athletes' Village built for the sports events can be considered a typical case of circular economy. By operating the Athletes' Village, it is possible to explore and practice the application of circular economy in the community, which will provide technical support for the future large-scale promotion of cleaner and more environmentally friendly production and living systems, thus contributing to sustainable development of the hosts (Khan et al, 2021c). Therefore, this study believes that organizing comprehensive sports events can realize the green and low-carbon development of each city through green technology innovation.…”

Large-scale sports events can improve public environmental awareness, strengthen urban governance, and push green innovation. However, it may also increase the burden on infrastructure, cause energy consumption, and lead to some pollution. Using the panel data of 278 cities in China from 2006 to 2019, this study systematically discusses how comprehensive sports events affect the green and low-carbon development of Chinese cities. First, the green total factor productivity and carbon emission efficiency calculated by the SBM-DEA model are taken as proxy variables of green and low-carbon development. And then, the spatial difference-in-differences (SDID) model is used to undertake empirical analysis and further test the impact mechanism and heterogeneity. Four main results are derived from this study: 1) the hosting of comprehensive sports events can significantly enhance the green and low-carbon development of cities. This result is still valid after a whole string of robustness tests; 2) comprehensive sports events have a significant positive spatial spillover effect on the green and low-carbon development of adjacent cities; 3) the mechanism analysis shows that comprehensive sports events can encourage green development of cities through technological innovation, sports industry development, and foreign investment, but through foreign investment, sports events cannot significantly affect the green total factor productivity and carbon emission efficiency of host cities; and 4) heterogeneity exists between the city rank and the event level. The promotional effect of comprehensive sports events on cities’ green and low-carbon development is more significant in first-tier cities and for international events.

“…The continuous deterioration in the state of the climate has raised serious concerns about mitigating its harmful effects (Khan et al, 2021c). It has now become imperative to discuss the causes and the possible solutions for curtailing the current levels of environmental contamination, which otherwise may cause irreparable damage to the world's environment, resources, and population.…”

For decades, renewable energy consumption has been presented as the ultimate solution to reduce pollutant gas emissions. However, their production, marketing, and, above all, consumption are not entirely climate neutral, so society needs new practices, such as circular energy, to achieve a more efficient energy transition (Khan et al., 2021a; Khan et al., 2021d). This study aims at exploring the effects of energy intensity, renewable energy consumption and forestation on CO2 emissions for developed and developing countries. Owing to cross-country income disparity, the data were categorized into four distinct groups: lower, lower-middle, upper-middle, and high-income over the period of 1980–2018. The Pedroni and Fisher-Johnson estimators of pooled data are employed for determining the plausible presence of a long-run co-integrating relationship between model variables. For all four country groups, Pedroni cointegration testing results reveal a significant long-run association between CO2 emission and its determinants. However, the Fisher-Johansen estimator yield mixed results, with low- and lower-middle income country groups outperforming the other two groups. However, the magnitude of this long-run association is less substantial, particularly in case of renewable energy consumption and forestation. For all country groups, energy intensity turns out to be the most influential long-run determinant of CO2 emissions, holding a positive coefficient value ranging from 0.30 to 1.31. Renewable energy consumption is the second most important long-run determinant of CO2 emissions. In case of forestation, the series imparts (statistically) significant long-run effects only for lower-middle-income countries. The overall results back the idea of curtailing the existing levels of energy intensity and encouraging the exploration and the use of renewable energy sources as a policy tool against controlling the prevalent situation of carbon-based emissions in our subject group of countries.
