“…In other words, as the percentage of the urban population increases, environmental pollution in the transport sector also increases. Therefore, the current situations of economic growth and urbanization in the country are not yet in a situation where economic growth and increased urban population reduce emissions of environmental pollutants, especially carbon dioxide as achieved in developed countries (See Adams et al, 2020;Hashmi et al, 2021).…”

Transport is an essential infrastructure for development. With its high share of gross domestic product (GDP), it makes a significant contribution to total CO2 emissions in Malaysia. It is therefore important to pay greater attention to reducing CO2 emissions and sustainable development in this sector. Therefore, this study aims at estimating the relationship between transport CO2 emissions and its key drivers using the Autoregressive Distributed Lag (ARDL) technique. The time period covered by the study extends from 1978 to 2018. It further investigates the response of CO2 emissions to shocks in the value of other variables by employing the generalized impulse response approach. The results suggest that urbanization is the major contributor to the increase in CO2 emissions followed by the carbon intensity of energy in the long-run. Carbon intensity of energy, GDP per transport worker and urbanization contribute significantly to increases in transport CO2 emissions in the short- and long-run. Testing the Environmental Kuznets Curve (EKC) hypothesis recommends that Malaysia continue to be on track to reach the highest level of income and welfare to give pay more attention to the environment. Therefore, the country maintains its CO2 emissions level in the future because of economic development. Therefore, these findings show that energy and environmental policymakers need to pay more attention to improving energy efficiency and the use of low-carbon technologies and electrification in the transport sector and the use of high-quality public transport, particularly in urban areas, for sustainable urban development.

“…The conclusion obtained was that urbanization was one of the variables that have the greatest influence [46]. However, in other cases, the opposite conclusion was reached [47]; or that the influence was shaped similar to an inverted U-shape [48]. In addition, the influence of urbanization on airport emissions at the city level was studied, reaching the conclusion that it exerts a strong positive correlation [49] Unlike what happens with energy consumption, the density variable was used in more research.…”

More than 50% of the world’s population lives in cities. Its buildings consume more than a third of the energy and generate 40% of the emissions. This makes cities in general and their buildings in particular priority points of attention for policymakers and utilities. This paper uses population density as a variable to know its influence on energy consumption and emissions produced in buildings. Furthermore, to show its effect more clearly, the influence of the climate was eliminated. The usual energy consumption in buildings is thermal and electrical. The study was carried out at the city level, both per inhabitant and per household. The area actually occupied by the city was considered. The proposed method was applied to the case of Spanish cities with more than 50,000 inhabitants. The results show that the higher the population density, the higher the energy consumption per inhabitant and household in buildings. The consumption of thermal energy is elastic, while that of electrical energy is inelastic, varying more than 100% between extreme groups. Regarding CO2 emissions, the higher the population density, the higher the emissions. Emissions of electrical origin barely vary by 2% and are greater than those of thermal origin. In addition, the proportion of emissions of electrical origin, with respect to the total, decreases with increasing population density from 74% to 55%. This research aims to help policymakers and utilities to take the appropriate measures that favor the use of renewable energies and reduce CO2 emissions.

“…Salahuddin et al ( 2019 ), using data from 44 sub-Saharan African countries from 1984 to 2016, found that urbanization was positively associated with CO 2 emissions in the long run whereas negatively in the short run. Hashmi et al ( 2021 ) examined the relationship between urbanization paths and CO 2 emissions in East Asian countries for the period 1971–2014 and found that urbanization improves environmental health in the long run, while energy intensity and economic growth reduce environmental performances. Using quantile regression, Lee et al ( 2022 ) explored the relationship between urbanization and greenhouse gas emissions for the selected 48 Belt and Road Initiative (BRI) countries from 1984 to 2017 and found that urbanization reduced environmental health.…”

“…Developing Asia is experiencing rapid economic growth, industrialization, and economic transformation and is considered a significant emitter of GHG emissions (Hanif et al 2019 ; Hashmi et al 2021 ; Lu et al 2017; Mohsin et al 2021 ). Rapid growth and economic transformation through increased consumption of non-renewable energy, less efficient technology, exploitation of natural resources, and limited investment in environmental protection and restoration (Ahmed et al 2022 ; Lee et al 2022 ) has significantly worsened the environmental degradation process.…”

Climate change resulting from a rapid increase in greenhouse gas (GHG) emissions is adversely affecting humanity. If the GHG emission continues to rise at the current pace, humanity will face severe consequences and reverse all the progress made. This paper, therefore, uses relevant data from 14 developing countries in Asia from 1990 to 2018 to examine the potential impact of environmental innovation on CO2 emissions by controlling globalization, urbanization, and economic growth. The number of environmental-related technology patents is used as a measure of environmental innovation. We employed a panel long-run regression model — FMOLS, PCSE, and FGLS to estimate the elasticity of CO2 emissions. For causal association among variables, we used Dumitrescu-Hurlin Granger causality tests. Our results show that renewable energy consumption and globalization have a significant impact in reducing CO2 emissions, while environmental technology innovations play a meager role in reducing emissions and only when economic growth support those type of investment. Furthermore, we found urbanization, oil consumption, and economic growth is detrimental to the environment, which is also evident in past studies. Therefore, countries should invest in renewable energy and environmental innovation aligned with the growth to reduce GHG emissions.
