“…As described in the previous sections, in addition to coal combustion, automobile emissions play a significant role in air pollution in cities (Davy et al, 2011;Amgalan et al, 2016). For the last ten years, the number of vehicles has increased in Ulaanbaatar by a factor of 4.5 and has reached ~540,000 (Bayasgalan and Matsumoto, 2017;NSOM, 2021). Approximately 72% of all vehicles were aged more than 10 years, and most of them were second-hand (Bayasgalan and Matsumoto, 2017).…”

Approximately 72% of all vehicles were aged more than 10 years, and most of them were second-hand (Bayasgalan and Matsumoto, 2017). In connection with automobile emissions, NO2 concentrations detected at roadside sites of NAMEM were in the range of 41-65 µg m -3 and exceeded national air quality guidelines for 97% of all measured days in 2014 (Bayasgalan and Matsumoto, 2017).…”

For the last decades, Mongolia has seen an extensive escalation in population growth, urbanization, and industrialization, together with great increase in mining and usage of vehicles. As a result, a substantial increase has taken place in the types and number of emission sources of air pollutants, especially in urban areas. During the cold season, air pollution level in Ulaanbaatar, the capital of Mongolia, is frequently ranked as the highest in the world. However, due to the lack of air quality management, the country is suffering from a deterioration of air quality.Despite the worse air pollution situation, due to insufficient research capacity of the country, to date, research works on characteristics of air pollution have mainly been based on current capability and/or collaboration with foreign institutes. The research gap in this area necessitates numerous investigations, which could have great importance in developing mitigating strategies and minimizing the adverse impact of air pollution on local and regional scales. This paper reviews previously available studies and reports in international scientific journals on air quality in Mongolia. Based on the existing research works, future needs of studies on ambient air pollution in Mongolia are suggested.

“…Therefore, applying strict policy standards for vehicle emissions could reduce these levels (Huo et al, 2012). Converting to the Euro standard for all vehicles, including those over ten years old, the CO, NO x , HC, and PM emissions will be significantly decreased (Batjargal, 2017). The change from Euro 2 to Euro 4 is considered an essential solution for decreasing air pollutants.…”

Jakarta had a congestion level of 53% in 2019, ranking 10th among the most traffic jams globally. Therefore, the transportation sector is the largest contributor to air pollution in the special area of the capital city Jakarta (DKI Jakarta). In this study, a vehicle age cohort was analyzed using dynamic models. Several factors, such as emission standards, vehicle speed, as well as fuel quality and type, were included to drive the models. The emission inventory for air pollutants, such as carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NO x ), and particulate matter (PM 10 ) can be calculated using this model. The results showed that motorbikes were the major contributor to the increase in the four pollutants in DKI Jakarta from 2007 to 2018 and will still be a significant contributor until 2040. In 2018, the major contributors to CO, HC, NO, and PM 10 were motorbikes (52.7%), motorbikes (79.6%), buses (63.9%), and motorbikes (74.7%), respectively. It is predicted that in 2040, using the business-as-usual (BAU) scenario, motorbikes will also be the primary contributors of air pollutants (CO, HC, and PM) 70.2%, 91.4%, and 82.9%, respectively. Diesel passenger cars will become a lesser contributor to air pollutants than all vehicles from 2018 to 2040 in DKI Jakarta.

“…Sources and literature show that the previous researches mainly emphasized on the air pollution caused by vehicle emission and fuel releasing impacts (Byambaa, B., 2019, Guttikunda, S.K., et al 2013, Bayasgalan, B. et al 2017 Environmental influences of auto repair service have not been studied yet, therefore a measurement of toxic substances and pollution intensity is considered as a priority of this study. The main purpose of this study was first, to assess the concentration of heavy metals in surface soil samples near some auto repair centers of Ulaanbaatar city, Mongolia.…”

Despite extensive political funding programs, the energy consumption in Germany for space heating and hot water stagnated on a high level of 870 TWh over the past few years and even exceeded the level of 2010. To reduce consumption and meeting the energy-efficiency goals set by the German federal government, an option for private homeowners is to participate in community energy systems (CES). However, homeowners' reluctance to join CES constitutes a major issue. Recent research has not provided deeper insights into reasons for this hesitation. Focusing primarily on local district heating systems, we use two theoretical approaches, motivation and attribution theory, to shed light on drivers and barriers in the decision-making process of homeowners. To gain insights, an explorative research design was chosen, and 22 problem-centered interviews were conducted with homeowners as well as experts.Our results show that subjectively perceived energy autonomy can be a barrier for private homeowners to participate in CES. Furthermore, we find a discrepancy between objective energy autonomy, as defined from a technical perspective, and homeowners' perception. Regarding this, the two major aspects shaping homeowners' perception of energy autonomy are (1) perceived independence from third parties as well as other external influences, and (2) a sense of control over the home energy system and its costs. Our study provides new insights into the decision-making process of homeowners to participate in CES. Additionally, we identified several implications in how far practitioners can address subjectively perceived energy autonomy issues to reduce inertia to join CES.
