“…The study domain is a mixed bag of several urban and rural entities and has an agriculture-dominated economy; therefore, it boasts of a rich urban–rural transport network weaved around the agriculture- and agro-based industries. For the high-resolution transport sector emission and activity data estimation, a novel methodology developed in our previous study is used . The methodology uses travel data to simulate movements of vehicles in the study domain.…”

Health and livelihood impacts from ambient air pollution among populations in developing countries are disproportional. These disparities are often overlooked due to a lack of information on microlevel emission data, especially in smaller cities and rural areas. The current work in an Indian district, Saharanpur, proposes the use of novel data sets to estimate microlevel emissions from air-polluting infrastructure sectors in urban and rural areas for use in pollutant transport models. Health impacts estimated based on the surface PM 2.5 concentration suggest that the rate of premature deaths is 158 (95% CI: 122− 163) and 143 (95% CI: 65−151) deaths per 100 000 people in urban and rural areas, respectively. Sixty-eight percent of the 6372 (95% CI: 3321−6987) annual premature deaths occurs in rural areas. Depicting higher contribution-exposure disparities among socioeconomic groups, the study observed that compared to their contribution to air pollution, low socioeconomic status (SES) groups in the region experience 6,7, 7, and 26% more premature deaths from PM 2.5 exposure for industries, household cooking fuel burning, open waste burning, and transportation, respectively. The majority of disability-adjusted life years (DALYs) in the study domain are observed in economically weaker worker categories. Reduced income due to the loss of these life years will significantly impact these groups due to their dependence on daily wages for basic life necessities. Microlevel pollution mitigation policies with a focus on these inequalities are critical for promoting environmental equity and justice.

“…Specifically, we decrease the road transportation attributable exhaust and evaporative emissions by 30% while keeping the non-exhaust emissions the same as the baseline scenario. This is because non-exhaust emissions from EVs will be equal to or greater than those associated with internal combustion engine vehicles depending on the vehicle weight and technology improvements like regenerative braking systems [58][59][60][61]. The reason we did not increase the non-exhaust emissions in the EV scenarios is because the kerb weight associated with EV counterparts currently available in India across various vehicle categories is either similar to or lower than the internal combustion engine vehicle in the same category [21].…”

Ambient air pollution in India accounts for 870,000 deaths per year, including 43,000 from road transportation. Vehicle electrification could posit a sustainable solution. However, 3/4th of India's electric grid is powered by coal, emitting large amounts of PM2.5, SO2, and NOx. This leads to uncertainty regarding the health benefits and distributional consequences from vehicle electrification. Our results show that if electric vehicles made up 30% of vehicle kilometers traveled, there would be 1,000-2,000 additional deaths each year under present day conditions. Higher increases in pollution exposure are seen in scheduled castes/tribes, poor, and rural populations particularly in high coal production states. Switching to net zero-emitting electricity generation for charging would reduce air pollution attributable deaths by 6,000-7,000 annually and PM2.5 exposure across all groups of population.

The aim of the research is to identify places with deteriorated air quality in the selected city. After an analytical analysis of the data, it is possible to propose steps that can be used to actively contribute to the reduction of air pollution, especially due to road traffic. Places where deteriorated air quality was identified were identified on the basis of practical measurements. Given that the measurement route was designed in a built-up area of the city with a large number of pedestrians, the research was primarily focused on the identification of particulate matters (PM) and the concentration of carbon monoxide CO. The measurements were performed repeatedly on a pre-defined route. The measurements were carried out repeatedly during the morning rush hour when traffic was congested on the roads. Based on the processing and evaluation of the measurements, the sections where increased values of individual emissions were recorded were determined. In this way, it is possible to precisely identify places where air quality deteriorates. The research conclusions provide support for planning the optimization of air quality management policies towards the creation of sustainable cities. The research results present the possibilities of identifying problematic sections from the point of view of emissions production. Critical places with regard to the production of emissions can be connected to places where a permanently increased movement of vehicles is observed.
