“…CO 2 emissions are a significant source of worry across the world. However, the impact on people’s quality of life and the environment varies by area and donates around 70% of total GHG emissions [ 24 , 25 ]. Developed economies traditionally lead global CO 2 emissions, and emerging economies’ rapidly increasing energy consumption put their aggregate emissions above the developed countries.…”

“…In 2005, industrialized economies accounted for over 40% of global CO 2 emissions, developing nations for around 56%, and aviation and maritime transport for the remaining 4% [ 54 ]. Africa economically lacks growth, wherein 21st-century electrification is still a problem and sticks to traditional biomass [ 25 ]. Although economic growth is an ultimate focus, under the existing interregional trade policy, growing recent economic activity in most African republics will result in considerable growth in FDI, energy usage, GEX, and CO 2 emissions by 2030 [ 55 ].…”

“…Firstly, even though several studies on Africa in the area of EG-EQ have been conducted [ 24 , 25 , 26 , 27 , 28 ] these researches have paid less attention to the GEX’s involvement in these outcomes hence, the magnitude of GEX in maintaining environmental quality as countries pursue economic growth have yet not to be established in NASA economies. Thus, this study is the first to use GEX, which adds to the current literature on the growth–environment quality model in NASA economies.…”

Environmental expenditures (EX) are made by the government and industries which are either long-term or short-term investments. The principal target of EX is to eliminate environmental hazards, promote sustainable natural resources, and improve environmental quality (EQ). Thus, this study looks at the impact of economic growth (EG), and government finance expenditure (GEX) on EQ in Northern Africa and Southern Africa (NASA) republics from 2000–2016. The panel quantile regression (PQR) and panel vector autoregressive (PVAR) model in a generalized method of moment framework (GMM) were employed as a framework. The PQR results show that; (i) In Northern republics, GEX had a significant positive effect on EQ at 25%, 50%, and 75% quantiles levels. (ii) In the Southern republics, GEX had a significant negative impact on EQ at 25%. Moreover, the PVAR through the GMM established that EG and GEX are significantly positive while the parameter for CO2 is insignificant and negative in the North. However, in the South, GEX and CO2 were statistically significant, while EG positively impacts EQ. Lastly, the granger causality report in North indicates uni-directional causation running from LNGEX → LNGDPpc, LNCO2 → LNGDPpc, LNFF → LNGEX, and LNFDI → LNGEX. Similarly, there is uni-directional causation in South republics from LNGEX → LNGDPpc, LNCO2 → LNGEX, and LNFDI → LNGEX.

“…There are two types of spatial weight matrices. One is geographical distance weight matrix, the other is economic distance weight matrix [52][53][54]. Since the economic distance weight matrix may cause endogeneity problems, this study uses the geographic distance weight matrix, which is set as shown in Equation ( 2).…”

The Impact of Environmental Regulation on Green Energy Technology Innovation—Evidence from China

2022

View full text Add to dashboard Cite

Green energy technology innovation (GETI) is a crucial path to achieve sustainable development. However, few studies have examined the determinants of GETI, especially from the perspective of environmental regulation. To fill this gap, this study investigates the impact of environmental regulation on GETI using the panel data of 30 provinces in Mainland China from 2001 to 2018. We first measure GETI by the latest IPC codes and patent data, and then adopt a dynamic spatial Durbin model (DSDM) to examine the relationship between environmental regulation and GETI. The main conclusions are summarized as follows: (1) There is a significant inverted U-shaped relationship between environmental regulation and GETI; (2) heterogeneity analysis shows that the inverted U-shaped correlation not only exists between environmental regulations and different types of GETI, but also exists between environmental regulations and GETI in different regions. Moreover, the results also show that the spatial spillover effect and path-dependent effect exist in all cases. The findings can provide reference for policymakers to formulate more precise environmental policies. That is, environmental policies in a province should be formulated based on its position on the inverted U-shaped curve. More specifically, when it is on the left side of the inflection point, it is reasonable to strengthen environmental policies, and when it is on the right side of the inflection point, appropriate relaxation of environmental policies should be considered.

“…According to the World Health Organization (WHO), it is estimated that seven million deaths a year are the product of environmental pollution arising from GHGs [ 5 ], and it is predicted that these deaths may amount to up to nine million in 2060 if the growing trend in CO 2 and GHG emissions continues [ 6 ]. The United Nations Development Program (UNDP) reveals that 91% of geophysical disasters are caused by climate change, and according to The Economist Intelligence Unit of the United States, it is estimated that, if adequate measures are not taken to combat this problem, climate effects can cost the world 7.9 trillion dollars and cause the world economy to lose 3% of gross domestic product (GDP) by 2050 [ 7 ].…”

Trends on CO2 Capture with Microalgae: A Bibliometric Analysis

et al. 2022

View full text Add to dashboard Cite

The alarming levels of carbon dioxide (CO2) are an environmental problem that affects the economic growth of the world. CO2 emissions represent penalties and restrictions due to the high carbon footprint. Therefore, sustainable strategies are required to reduce the negative impact that occurs. Among the potential systems for CO2 capture are microalgae. These are defined as photosynthetic microorganisms that use CO2 and sunlight to obtain oxygen (O2) and generate value-added products such as biofuels, among others. Despite the advantages that microalgae may present, there are still technical–economic challenges that limit industrial-scale commercialization and the use of biomass in the production of added-value compounds. Therefore, this study reviews the current state of research on CO2 capture with microalgae, for which bibliometric analysis was used to establish the trends of the subject in terms of scientometric parameters. Technological advances in the use of microalgal biomass were also identified. Additionally, it was possible to establish the different cooperation networks between countries, which showed interactions in the search to reduce CO2 concentrations through microalgae.
