Summary: Household access to clean energy is essential for public health and environmental preservation in low- and middle-income countries. This study proposes a hierarchy of reduction potentials for household energy emissions, taking into account various implementation barriers such as distributional, technical, economic, and market factors. By applying this framework to India, the researchers found that implementing reduction programs within a certain distance from urban centers can achieve a significant portion of the theoretical reduction potential. Additionally, the study emphasizes the importance of considering the factors that affect transitions to clean energy solutions rather than solely quantifying baseline emissions in emission inventory development.

Summary: The paper provides a comprehensive analysis of vehicular fleet and mobile source emissions in Bahia Blanca, Argentina in 2018. Motorcycles were identified as the main source of CO, NMVOC, CO2 and CH4, while light commercial vehicles emitted the most amount of NOx. Despite the growth of the vehicular fleet, emissions in 2018 were lower than in 2013, attributed to the incorporation of more efficient emission control technology. However, this improvement resulted in increased GHGs emissions, presenting a continued challenge in the area.

Summary: Gaseous and particulate chlorine species play a crucial role in various aspects of the atmosphere, including oxidation capacity, aerosol water uptake, visibility degradation, and human health. A comprehensive global emission inventory reveals that HCl emissions are mainly from industries such as open waste burning and biomass combustion, while pCl emissions are mainly from biofuel and open biomass burning processes. The sectoral and spatial distributions of these emissions are heterogeneous, and the temporal trends are influenced by various factors.

Summary: The emission inventories for Vietnam Thermal Power Plants developed in 2010 and 2015 showed coal-fired power plants had the highest emissions and the largest uncertainty in NOx. The Red River Delta region had the largest emissions of CO2, N2O, SO2, NOx, PM10, PM2.5, BC, and OC from coal-fired TPPs, while the Southeast region had the largest sources of CO, NMVOC, and CH4 caused by gas-fired TPPs. The growths of NOx, CO, NMVOC, PM10, PM2.5, BC, OC, CO2, CH4, and N2O emissions increased significantly from 2010 to 2015, while there was a 19% reduction in SO2 emissions due to the decommissioning of oil-fired TPPs.

Summary: Emissions of organic compounds have significant impacts on the environment. Previous emission inventories focused on only a portion of these compounds, neglecting the contribution of semivolatile and intermediate volatile organic compounds to organic aerosol burden. This study developed a comprehensive emission inventory for China from 2005 to 2019, revealing changes in the sources and formation potential of organic aerosols. Findings indicate a decline in emissions of low/extremely low/ultralow VOC and SVOC after 2014, while emissions from volatile chemical products increased significantly and became the dominant source. These results highlight the importance of considering VCP, residential biomass burning, and diesel vehicles in future air pollution control policies.

Summary: This study evaluates for the first time the overlapping conditions and causal mechanisms of energy poverty and transport poverty in Ireland, finding a widespread presence of both and a lack of public knowledge on related factors and solutions. Moreover, self-reported data does not align with expected outcomes. Therefore, precise targeting of individuals and households for support measures is not optimal for decarbonization and alleviating energy and transport poverty conditions, and some relevant policy implications are suggested.

Summary: As an alternative to traditional and electric vehicles, e-cargo bikes have the potential to improve urban logistics sustainability, especially for last-mile deliveries. This study models e-cargo bike trips from a small business rental scheme and assesses the effects of trip length and rainfall conditions on the attractiveness of e-cargo bikes as a mode of goods delivery. A hybrid modelling framework is built and evaluated through a case study in Dublin, Ireland. The study shows that small businesses prefer e-cargo bikes for goods delivery over longer distances in warmer and drier weather conditions. There is a strong interaction effect between weather and distance, with temperature exacerbating the deterring effect of wet weather.

Summary: The impacts of climate change have led to government commitments to implement policies to limit rising temperatures. One strategy is to phase out internal combustion engines in favor of electric vehicles, which various transportation services, including FREE NOW, have adopted. This study analyzes the composition of FREE NOW's taxi fleet in Dublin in 2021 and examines the emissions reduction achievable by fully electrifying the fleet. Different scenarios involving different vehicle powertrain and fuel configurations were modeled using an emissions tool. Results show a 77% decrease in carbon dioxide emissions from complete electrification. Multi-criteria analysis was used to evaluate strengths and weaknesses of each scenario. The S5 scenario, consisting of electric vehicles only, scored highest on many criteria. S-5 was identified as the best option for the taxi fleet, followed closely by S-4 which involved upgrading to plug-in hybrid EVs. The study highlights the need for infrastructure improvements to achieve the all-EV target by 2030 in Dublin.

Summary: This research uses a Geographic Information System (GIS) based approach to identify suitable locations for community Electric Vehicle charging points. The charging infrastructure is categorized into three types - shared-residential, en-route, and destination charging - with selection criteria based on targeted end-users' characteristics. The study identifies 770 ideal locations in Dublin for initial charging infrastructure installation, and 3080 sites for later implementation to meet the charging requirements projected by the Dublin Local Authority for 2030. The population served by proposed residential charging points is determined based on convenience of accessibility within a five-minute walk or five-minute cycle. The study's findings can be valuable for practitioners deploying charging stations in the region, and the proposed methodology can be adapted globally in similar cities.
