“…This large reduction is the result of the implementation of more stringent emission standards and scrappage of older diesel vehicles. 28 Generally, the average BC concentrations during the 2020 nonholiday campaign (7.7 μg m −3 ) were higher than in the 2020 holiday campaign (4.4 μg m −3 ) by 43%. This is due to the fact that a large number of HDDVs were not operating during the holidays.…”

The relative contribution (BCsfb/BCtr ratio) of black carbon (BC) from traffic and solid fuel burning were evaluated in different microenvironments. We used a mobile platform to measure concentrations of BC and Delta-C (DC) in four microenvironments (diesel plume, urban freeway, urban street, and rural freeway). A total of 38,661 measurements of BC and DC concentrations each averaged over 5 s (in winter 2018 and fall 2020) were used to evaluate the BCsfb/BCtr ratio. Measurements were divided into three sampling campaigns (2018 nonholiday, 2020 nonholiday, and 2020 holiday) to evaluate holiday and ambient temperature impacts on the BCsfb/BCtr ratio. There was a large reduction of BC but not DC concentrations during holidays. We found elevated BCsfb/BCtr ratios in winter 2018 and fall 2020 that can be related to residential heating and cooking, respectively. A strong linear relationship (R 2 = 0.89, p < 0.05) between DC/BC ratios and BCsfb/BCtr ratios in the four microenvironments is shown as evidence that the DC/BC ratio is an indicator for solid fuel burning emissions and is independent of sampling technique and location. The relationship between DC/BC and BCsfb/BCtr ratios can be further used to quantitatively discern BC contributions from traffic and solid fuel burning emissions regardless of the type of microenvironments.

The study intends to assess the role of financial decentralization on carbon taxation and carbon emission to recommend the way forwards for economic recovery. To estimate the nexus, study applied the cointegration analysis technique, CGE estimation model, long-run analysis using t-CGE model, and robustness analysis technique on Chinese data. Research findings declare that financial decentralization has significant role on extending the carbon taxation in China and financial decentralization supported 14.92% to expand carbon taxation throughout the Chinese industries. In such industries, pollution emission industries are the top of the list including transportation industry and other manufacturing companies. Overall, manufacturing industries size is about 78% and 11% size of transportation industry is included. Correspondingly, the findings also revealed that financial decentralization supports climate change mitigation with 29% and carbon taxation limits carbon emission with 44% in Chinese industries. Study directs to the stakeholders to enhance carbon taxation schemes in all sectors of the all the industries of China and come up with the viable policy action so that the desired sustainable development goals may achieve effectively. Hence, stakeholders need to consider recommendations of preceding research to enhance green economic recovery.

“…Reducing emissions of BC is particularly important where SLCPs are concerned, but international law does not yet provide clear answers as to how such emissions are to be regulated. For BC, a recent study [ 61 ] showed that the major benefits in reducing BC emissions from China result from more stringent emission standards and the accelerated retirement of older heavy-duty diesel vehicles. The shorter atmospheric lifetime of BC compared to CO 2 implies that the mitigation of BC emissions would offer an important opportunity to alleviate global warming in the short term.…”

Airborne particulate matter (PM) is a pollutant of concern not only because of its adverse effects on human health but also on visibility and the radiative budget of the atmosphere. PM can be considered as a sum of solid/liquid species covering a wide range of particle sizes with diverse chemical composition. Organic aerosols may be emitted (primary organic aerosols, POA), or formed in the atmosphere following reaction of volatile organic compounds (secondary organic aerosols, SOA), but some of these compounds may partition between the gas and aerosol phases depending upon ambient conditions. This review focuses on carbonaceous PM and gaseous precursors emitted by road traffic, including ultrafine particles (UFP) and polycyclic aromatic hydrocarbons (PAHs) that are clearly linked to the evolution and formation of carbonaceous species. Clearly, the solid fraction of PM has been reduced during the last two decades, with the implementation of after-treatment systems abating approximately 99% of primary solid particle mass concentrations. However, the role of brown carbon and its radiative effect on climate and the generation of ultrafine particles by nucleation of organic vapour during the dilution of the exhaust remain unclear phenomena and will need further investigation. The increasing role of gasoline vehicles on carbonaceous particle emissions and formation is also highlighted, particularly through the chemical and thermodynamic evolution of organic gases and their propensity to produce particles. The remaining carbon-containing particles from brakes, tyres and road wear will still be a problem even in a future of full electrification of the vehicle fleet. Some key conclusions and recommendations are also proposed to support the decision makers in view of the next regulations on vehicle emissions worldwide.
