“…A similar investigation by Panoutsou et al [17] and Dias et al [18] reported that the replacement of petrol and diesel fuels with biofuels helps to improve engine performance, reduces nitrogen oxides (NOx) and particulate matter emissions, decarbonize the transport sector, and improved the efficiency of the vehicles. The fuel consumption and environmental assessment of biofuels in transport vehicles in Ethiopia reported that the use of bioethanol produced from sugarcane molasses saves 83 % fossil energy and reduces GHG emissions by 39 % while biodiesel generated from jatropha ensures 77 % energy savings and reduction of tailpipe GHG emissions by 79 % [19]. The application of biodiesel as an alternative fuel for vehicles in India [20], bioethanol in Poland and Brazil [21], biomethane in Sweden [22], and biohydrogen in the West Midlands region of England [23] reduces GHG emissions, contributes to air quality, and ensures return on investments.…”

Human beings naturally move from one location to another in search of basic necessities. Road transportation is a low-cost, versatile, and widely accessible mode of transportation worldwide. However, using fossil-based (FB) fuels in transportation vehicles is inefficient, generates hazardous gases, and worsens environmental degradation. The current work assesses the application of clean fuels such as biofuels, natural gas, electricity, propane, and other emerging fuels to replace FB fuels in transport vehicles. Unlike FB fuels, the use of biohydrogen, biomethane, biodiesel, and bioethanol in transport vehicles resulted in emission reduction by 70 %, 63 %, 41 %, and 54 %, respectively, while electric vehicles lower maintenance costs, ensuring better engine performance, and better engine efficiency. The adoption of natural gas and propane as alternative fuels for transport vehicles is cost-effective, and promotes environmental sustainability. There is a need for targeted financial, infrastructural, and technical investments to further promote the application of these clean fuels for road transport application. The outcome of the study provides updated information and sensitizes automobile engineers, environmentalists, transport fleet operators, governments, and other stakeholders on the benefits derivable in the adoption of clean fuels as alternatives to FB fuels as transport vehicles fuel.

“…Third, the feedback hypothesis is valid if there is a two-way causal link between renewable energy and TCO 2 e, which reveals that the deployment of renewables causes TCO 2 discharges and therefore TCO 2 emanations induce renewable energy. Finally, the neutrality hypothesis reveals that no causal link exists between renewable energy and TCO 2 e. In a such case, renewable energy consumption does not play a pivotal role in curbing TCO 2 e. The third strand of research applies a crosssection analysis based on country provinces or sectoral-based analysis (Singh et al, 2014;Dias et al, 2019;Desta et al, 2022a;Zeng et al, 2022). However, after an in-depth search of the literature on the renewable energy-TCO 2 e nexus, despite mixed results, one can claim that there are very limited empirical studies especially on biofuels and solar energy, which calls for a fresh look through a novel approach or intuitively appealing methodological innovation.…”

Given the unprecedented level of air pollution in urban areas, green transport systems has been a subject to an important debate in academic and policymaking circles. Despite the considerable outputs of the attendant literature, most of empirical studies to date have relied on conventional econometric models in which structural shocks are not controlled. This study, therefore, aims to offer a new perceptive of the dynamic connection between renewable energy, environment-related technological innovation, and transport-based CO2 emissions in Turkey during 1990Q1 to 2014Q1 by applying the Structural Vector Autoregressive approach (SVAR). Furthermore, to explore the co-movements and the lead-lag interrelations among the study variables, the wavelet coherence technique was used. The wavelet coherence technique circumvents the other traditional causality approaches by detecting the causal interrelation between the underlying series at different frequencies. The findings disclose that environment-related technological innovation has no reliable power to explain the variation in CO2 emissions from the transport sector. Solar energy is found to impact the CO2 emissions positively in the long run, while biofuels hold the same effect in short run. Moreover, per capita GDP and urbanization significantly impact the carbon emissions from the transport system in the long run with a negative sign. The wavelet analysis reveals that renewables and environmental-related technological innovation lead the transport-based CO2 emissions. The fourth and 16th periods are the most dominant frequencies. Accordingly, the study suggests that innovation in environment-related technologies is not enough to mitigate the pollution that stemming from the transport system in Turkey, it should be accompanied by strong and effective environmental measures. These policies might include environmental taxations, carbon pricing and trading schemes, which aim not only to prevent the pollution and over-extraction of resources, but also to promote the public revenues from different activities that related to environmental purposes and other applications such as energy product and vehicle fuels. In addition, it is suggested to strengthening the transportation system through the deployment of renewables and high-tech eco-friendly modes of transportation.
