From a paper by Heru Wahyudi, Sabila Ramadani, and Ukhti Ciptawaty:
“Human welfare can decrease as a result of a polluted environment. This study aims to examine the relevance of the Environmental Kuznets Curve (EKC) theory in OPEC member countries; besides that, this study also wants to see the effect of GDP per capita and fossil energy consumption on carbon dioxide gas emissions in OPEC countries. Method: this research is included in the descriptive quantitative method using the panel data regression method. The data used in the 2005-2020 period comes from the World Bank and Our World. Namely the GDP per capita variable, the carbon dioxide emission variable and fossil energy consumption. The results obtained from this study are that the hypothesis in EKC theory is relevant or occurs in OPEC member countries. In addition, per capita GDP and fossil energy consumption also positively affected OPEC member countries for the 2005-2020 period. It means that an increase in the economy will cause environmental damage by increasing the concentration of carbon dioxide gas emissions due to the use of fossil energy. However, at some point, a high economy will reduce environmental damage due to an economic orientation that focuses on the environment so that it uses environmentally friendly energy.”

From a paper by Charlotte Liotta and Jeroen van den Bergh:
“The long-standing growth-versus-environment debate has centered on national and global scales, devoting little attention to cities despite steadily increasing urban concentrations of population, activities and emissions. This Perspective clarifies how this debate plays out for cities by relating four urban growth dimensions—economic, population, spatial and environmental—to the narratives of green growth, degrowth and post-growth. To this end, we review theoretical and empirical insights about links between growth dimensions. Specific issues addressed include horizontal spillovers among cities, vertical policy integration and local experiments. Thus we connect the abstract growth-versus-environment debate to evidence regarding urban environmental policy.”

From a paper by Boyang Lia, Runze Chena, and Yuqin Dua:
“The power generation mix in China heavily relies on fossil energy sources, impeding
the advancement of clean power generation and emission reduction efforts. This paper
presents a macroeconomic model incorporating Emissions Trading Systems (ETS),
clean energy subsidies, and intertemporal learning behavior. It examines how carbon
pricing and clean subsidy policies influence the power generation sector and emission
reduction goals. The findings indicate that (1) pricing strategies based on total
emissions effectively drive emission reductions but may not adequately incentivize
cleaner energy transitions. (2) Increasing clean energy subsidies encourages a shift
towards cleaner technologies, although the impact on emission reductions is moderate.
(3) Combining both policies proves to be more effective than implementing either one
alone. (4) There exists a gap in understanding the clean power generation industry, with
both policies contributing to knowledge accumulation in this sector. The insights from
this study are valuable for countries employing ETS mechanisms.”

From a paper by Muhammad Ibrahim Shah, Matteo Foglia, Umer Shahzad, and Zeeshan Fareed:
“This paper investigates how oil price, COVID-19, and global energy innovation can affect carbon emissions under time- and frequency-varying perspectives. We contribute to the literature by being the first research to document the relationship between these variables in the short and long run (dynamically) at different frequencies in a multivariate context, thus providing a more detailed picture of the forces driving CO2 emissions. For this purpose, we use a novel methodology, i.e., the wavelet local multiple correlation (WLMC) recently developed by Polanco-Martínez et al. (2020). The results provide fresh evidence of long-run asymmetric dynamic correlations, highlighting how the oil price plays a key role in the dynamics of CO2 emissions. Moreover, we find that, during the long period, there is a strong negative co-movement between CO2 and the global energy innovation index, i.e., more investment in clean energy induces less emission. Supported by our findings, this research suggests crucial policy implications and insights for the governments worldwide in their efforts to revive their economies amidst the pandemic and environmental uncertainties.”

From a paper by Roy Cerqueti, Raffaele Mattera, and Saverio Storani:
“This paper develops a class of complex network-based models whose interconnected nodes are commodities. We assume that the considered commodities are linked on the ground of the similarities of risk profiles and correlations of their returns. In this framework, we explore the resilience of the networks — i.e., their ability to absorb exogenous microscopic shocks. To this aim, we assume that high levels of resilience are associated with small variations of the community structure of the network when an exogenous shock occurs — hence, assuming that the stability of the networked commodities is measured through the maintenance of their connection levels. Shocks are conceptualized as impulsive modifications of the links among the considered commodities. The employed methodological instrument is the clustering coefficient, which is a nodal centrality measure describing the way the adjacent of the nodes are mutually connected. The theoretical proposal is empirically tested over a large set of commodities of different nature.”
