In order to achieve the goal of carbon neutrality and explore the impact of COVID-19 on urban road carbon emission, this study applied and improved a near real-time road carbon emission estimation method for typical Chinese urban agglomeration to improve the rapid evaluation of sustainable development. As a result, we recorded the daily road carbon emission for 12 cities in the Beijing–Tianjin–Hebei (JJJ) region under the impact of the epidemic, exploring the road carbon reduction effect caused by COVID-19. Singular value decomposition method was used to analyze the temporal and spatial characteristics of road carbon emission changes among cities and to explore the urban resilience oriented to public events. The results show: (1) In the JJJ region, the carbon reduction effect caused by COVID-19 is significant, but it lasted for a short time. In the three periods—before the epidemic, strict lockdown period, and post-lockdown period for prevention and control—the total daily road carbon emissions in the 12 cities were 170,000–190,000 tons, 90,000–110,000 tons, and 160,000–180,000 tons, respectively. (2) Cities in the JJJ region showed different road carbon reduction potential under short-term administrative control. During the “strict lockdown period” (23 January–25 February 2020), the average change rate of road carbon emissions in Beijing was −78.72%, which had great potential for reduction. However, the average change rates of Xingtai and Zhangjiakou were only −7.53% and −8.66%, respectively. (3) There are spatiotemporal differences in carbon emissions of urban roads in the JJJ region under the impact of the epidemic. During the gradual reduction of COVID-19 restrictions, great differences between cities on weekends and holidays arise, showing the road carbon emissions in Beijing on weekends and holidays are far lower than that in other cities. (4) In the face of public emergencies, the larger the city is and the more complex the function of the city is, the more difficult for the city is to maintain a steady state. This study not only provides an idea for the dynamic monitoring of urban carbon emissions to improve the rapid evaluation of urban sustainable development in post- and pre-lockdown but also fills the gap in the research on the differences in the response of cities to sudden security incidents from the perspective of road carbon emissions.

This article addresses the need for the United States to reduce emissions from the transportation sector. In order to concisely evaluate the political discussion of promoting renewable energy use and discouraging reliance on fossil fuels, this article focuses on the adoption of electric and hybrid vehicles as a means of illustrating the larger policy challenge of how to maximize policy effectiveness at reducing emissions while minimizing economic disruption. The article estimates the magnitude of electric and gas-powered vehicles purchases in response to either a subsidy or a tax and discusses the positive and negative outcomes of each policy approach. The article finds that while a tax on carbon emissions may be most effective in removing gas-powered vehicles from the road, it will disproportionately affect lower-income households. Implementing substantial subsidies for electric vehicles, funded through a smaller tax on carbon emissions, is suggested as a solution to reduce the regressive impacts of a standalone carbon tax.

buy this issue Climatologist James Hansen's 2018 "Climate Change in a Nutshell: The Gathering Storm," known as the Nutshell document, is the single most important analysis currently available for general readers seeking to stay abreast of the science and politics of global warming. Nevertheless, denial of the extent of the conflict between capitalism and the climate remains pervasive. Such views were subjected to a strong refutation by Enno Schröder and Servaas Storm in a November 2018 paper entitled "Economic Growth and Carbon Emissions: The Road to 'Hothouse Earth' Is Paved With Good Intentions."

The transportation industry is the second largest industry of carbon emissions in the world, and the road transportation industry accounts for a large proportion of this in the global transportation industry. The carbon emissions of the road transportation industry in six Asia-Pacific countries (Australia, Canada, China, India, Russia, and the United States) accounts for more than 50% of this in the global transportation industry. Therefore, it is of great significance to study driving factors of carbon emissions of the road transportation industry in six Asia-Pacific countries for controlling global carbon emissions. In this paper, the Logarithmic Mean Divisia Index (LMDI) decomposition method is adopted to analyze driving factors on carbon emissions of the road transportation industry in six Asia-Pacific countries from 1990 to 2016. The results show that carbon emissions of the road transportation industry in these six Asia-Pacific countries was 2961.37 million tons in 2016, with an increase of 84.43% compared with those in 1990. The economic output effect and the population size effect have positive driving influences on carbon emissions of the road transportation industry, in which the economic output effect is still the most important driving factor. The energy intensity effect and the transportation intensity effect have different influences on driving carbon emissions of the road transportation industry for these six Asia-Pacific Countries. Furthermore, the carbon emissions coefficient effect has a relatively small influence. Hence, in order to effectively control carbon emissions of the road transportation industry in these six Asia-Pacific countries, it is necessary to control the impact of economic developments on the environment, to reduce energy intensity by promoting the conversion of road transportation to rail and water transportation, and to lower the carbon emissions coefficient by continuously improving vehicle emission standards and fuel quality.

The paper aimed at establishing the relationship between age, engine capacity, fuel type and fuel efficiency and carbon emissions. The relationship was obtained using panel data on newly imported registered vehicle stock obtained from Uganda Revenue Authority. This involved collecting data on imported vehicle inventory into Uganda for the period from 2013 to 2017 which was later analysed using the stata software. The findings indicated a positive relationship between a vehicles age, engine capacity, vehicle category (Light Duty Vehicles, Medium Duty Vehicles and Heavy Duty Vehicles) and fuel efficiency and carbon emissions. A comparison with the global fuel efficiency targets indicated that more fuel was being consumed in Uganda compared to non-OECD countries. A reduction in fuel consumption and emissions was observed in petrol vehicles while diesel vehicles had increased carbon emissions and fuel consumptions due to an increase in engine capacities. The findings imply that government should develop policy options that promote vehicle fuel efficiency, transport system operators may undergo training in fuel efficiency issues that will result in an attitudinal change while academicians need to carry out more research comparing the effect of transport systems operators ages, level education and income on carbon emissions and fuel efficiency. The majority of research on fuel efficiency and carbon emissions uses survey data rather than panel data. Further, previous research is focused on vehicles that are already on the road rather than focusing on the effect of age, engine capacity, fuel type on fuel efficiency and carbon emissions.

The road and marine transportation sectors have attracted a great deal of attention as one of the main sources of carbon emissions. In this study, a LEAP (long-range energy alternatives planning system) model is used to predict the energy demand and carbon emissions of the road and marine transportation sectors in Guangdong Province from 2016 to 2030. Based on the model results, if Guangdong Province does not adopt new control measures, in 2030, the energy demand and CO2 (carbon dioxide) emissions from the road and marine transportation sectors will have increased by 117 and 116%, respectively, compared to the levels in 2015. Conversely, under a low-carbon scenario, carbon emissions will peak by 2027 in Guangdong Province. Motor vehicle control measures generate the strongest reduction in energy consumption and CO2 emissions for the road and marine transportation sectors in Guangdong Province. Furthermore, the reduction of emissions resulting from these measures would increase over time. Public transportation development and the promotion of clean energy measures also play significant roles in reducing carbon emissions long-term. The contribution of road passenger transport to emission reduction is the largest, followed by marine freight transport and road freight transport. While the energy demand and carbon emissions peak at a similar time in the model, the peak time for CO2 occurs slightly earlier.

Despite the considerable advances in molecular biology over the past several decades, the nature of the physical–chemical process by which inanimate matter become transformed into simplest life remains elusive. In this review, we describe recent advances in a relatively new area of chemistry, systems chemistry, which attempts to uncover the physical–chemical principles underlying that remarkable transformation. A significant development has been the discovery that within the space of chemical potentiality there exists a largely unexplored kinetic domain which could be termed dynamic kinetic chemistry. Our analysis suggests that all biological systems and associated sub-systems belong to this distinct domain, thereby facilitating the placement of biological systems within a coherent physical/chemical framework. That discovery offers new insights into the origin of life process, as well as opening the door toward the preparation of active materials able to self-heal, adapt to environmental changes, even communicate, mimicking what transpires routinely in the biological world. The road to simplest proto-life appears to be opening up.
