“…Government expenditure changes may end up either from an expansionary (EFP) or from a contractionary (CFP) fiscal policy. To boost industrial production, EFP also causes less eco-friendly technology to use more fossil fuels and CO2e [1][2][3]. Moreover, tax incentives in the FP have positive and a considerable outcome on CO2e [4,5].…”

Governments use fiscal and monetary policies to direct the economy toward economic expansion. However, both policies could have impacts on the environment. The study investigates the effects of fiscal and monetary policy, energy consumption and economic growth on carbon dioxide emissions for the Turkish economy from 1978 to 2021 with novel nonlinear bootstrapping NBARDL and nonlinear NBVARDL for nonlinear causality testing. The methods are robust to degenerate cointegration. By differentiating between expansionary and contractionary fiscal and monetary policies, the results determined the presence of long-run cointegrated relationships between the analyzed variables and emissions. The positive effects of both economic policies on emissions cannot be rejected, which become particularly pronounced for expansionary policies in addition to emission enhancing effects of energy consumption and growth. The effects of contractionary monetary policy are also positive in contrast to a set from the literature. Nonlinear causality tests favor one-way causality from energy consumption and from growth to emissions. The one-way causality from energy consumption and economic growth to emissions suggest non-existent feedback effects, leading to concerns for the environment. Expansionary and recessionary fiscal policies have one-way causal impacts on energy, leading to further environmental degradation. The findings highlight the severity of environmental problems caused by economic policies. Important policy recommendations are generated.

“…2 However, conventional hydrogen production is often accompanied by large amounts of CO 2 emissions that contribute to global climate change. 3 Therefore, it is crucial to reduce the negative environmental impacts caused by the CO 2 in the conventional hydrogen production industry. Thus, the strategic goals of carbon peaking and carbon neutrality in China can be achieved and sustainable energy production can be realized.…”

The addition of sorbent to capture CO2 in steam methane reforming has become a method to reduce CO2 emissions in conventional hydrogen production. The aim of this paper is to propose a fast method for predicting the capture performance of sorbents by applying the eXtreme Gradient Boosting (XGBoost) method. First, the effects of inlet temperature, velocity, CO2 mass fraction, and initial material inventory height on the sorbent CaO capture efficiency and resulting flow regime are systematically analyzed, while an extensive database is constructed. Second, a comparative assessment is conducted to determine the relative significance of the four parameters in influencing the capture efficiency. Finally, the XGBoost model is trained and deployed to enhance the computational accuracy of capture efficiency predictions. The results emphasize that temperature has the most significant effect on capture efficiency. Increasing the temperature and decreasing the gas velocity helped to increase the capture efficiency. The initial material inventory height of 0.3 m proved to be favorable for CO2 capture compared to 0.1 and 0.2 m, especially under gas velocity conditions of 0.3 m/s. In addition, the XGBoost model can be used to quickly predict the CO2 capture efficiency of fluidized beds by using less training data and obtaining the prediction result with a high accuracy of R2 = 0.9699 in 2 s. This model has potential applications for the prediction of the sorbent capture efficiency.

“…The chemical industry is essential to modern economies; it consumes a significant amount of raw material and energy and is responsible for significant carbon dioxide (CO 2 ) emissions (Durán‐Romero et al, 2020). The chemical industry uses a substantial quantity of non‐renewable energy, including natural gas, petroleum products, and coal, considered the main sources of CO 2 (Xin et al, 2022). Among industrial consumers, the chemical sector consumes the most energy and is the third industrial subsector in terms of direct CO 2 emissions.…”

This study describes the relationships between climate change and the concept of a circular economy, outlining the need for synergies within a company's context. It reports on a bibliometric analysis of the relations between climate change and circular economy, and it provides evidence and assessments based on a sample of 11 large companies in the chemical industry. The results show that there is a concern in the academic literature to discuss circular economy efforts to combat climate change, reduce carbon emissions, strengthen the supply chain, assess the life cycle of products, their environmental impact, and waste management, and identify barriers to implementing the circular economy. In addition, there is a close association between the CE concept and tackling climate change in how organisations report their practices to the stakeholders, in considering concepts of recycling, reusing, adopting renewable energy, seeking resource efficiency, and rethinking strategies. The study concludes by providing some suggestions that may assist companies in intensifying their efforts to reduce their carbon footprint, combining them with more circular business models. Efforts from interested stakeholders must focus on defining CE in a more detailed manner, as well as its implementation at the different stages of production and consumption, especially in operations for which no uniform approach or common practice can be established. In this context, implications for positive social and environmental impacts by promoting a faster and more proactive climate transition in the chemical sector are presented. The novelty of this paper relies on the fact that it advances knowledge on matters related to the circular economy under a climate change context, identifying current trends and suggesting some measures which may optimise current business practices of the chemical sector.
