The emissions of CO2 gas caused by transport in urban areas are increasingly serious, and the public transport sector plays a vital role in society, especially when considering the increased demands for mobility. New energy technologies in urban mobility are being introduced, as evidenced by the electric vehicle. We evaluated the positive environmental effects in terms of CO2 emissions that would be produced by the replacement of conventional urban transport bus fleets by electric buses. The simulation of an electric urban bus conceptual model is presented as a case study. The model is validated using the speed and height profiles of the most representative route within the city of Madrid—the C1 line. We assumed that the vehicle fleet is charged using the electric grid at night, when energy demand is low, the cost of energy is low, and energy is produced with a large provision of renewable energy, principally wind power. For the results, we considered the percentage of fleet replacement and the Spanish electricity mix. The analysis shows that by gradually replacing the current fleet of buses by electric buses over 10 years (2020 to 2030), CO2 emissions would be reduced by up to 92.6% compared to 2018 levels.

In order to electrify the transport sector, scores of charging stations are needed to incentivize people to buy electric vehicles. In urban areas with a high charging demand and little space, decision-makers are in need of planning tools that enable them to efficiently allocate financial and organizational resources to the promotion of electromobility. As with many other city planning tasks, simulations foster successful decision-making. This article presents a novel agent-based simulation framework for urban electromobility aimed at the analysis of charging station utilization and user behavior. The approach presented here employs a novel co-evolutionary learning model for adaptive charging behavior. The simulation framework is tested and verified by means of a case study conducted in the city of Munich. The case study shows that the presented approach realistically reproduces charging behavior and spatio-temporal charger utilization.

Production Of Hydrogen

Achieving the CO2 reduction targets for 2050 requires extensive measures being undertaken in all sectors. In contrast to energy generation, the transport sector has not yet been able to achieve a substantive reduction in CO2 emissions. Measures for the ever more pressing reduction in CO2 emissions from transportation include the increased use of electric vehicles powered by batteries or fuel cells. The use of fuel cells requires the production of hydrogen and the establishment of a corresponding hydrogen production system and associated infrastructure. Synthetic fuels made using carbon dioxide and sustainably-produced hydrogen can be used in the existing infrastructure and will reach the extant vehicle fleet in the medium term. All three options require a major expansion of the generation capacities for renewable electricity. Moreover, various options for road freight transport with light duty vehicles (LDVs) and heavy duty vehicles (HDVs) are analyzed and compared. In addition to efficiency throughout the entire value chain, well-to-wheel efficiency and also other aspects play an important role in this comparison. These include: (a) the possibility of large-scale energy storage in the sense of so-called ‘sector coupling’, which is offered only by hydrogen and synthetic energy sources; (b) the use of the existing fueling station infrastructure and the applicability of the new technology on the existing fleet; (c) fulfilling the power and range requirements of the long-distance road transport.

This article empirically applies Knut Laaser’s integrated conceptual framework, combining Sayer’s moral economy (ME) theory with labour process theory (LPT), to examine how two rival Irish unions engaged with an uneven moral economy and consciously sought to build collective worker solidarity during a dispute over competitive tendering and marketization. Using qualitative data from a case study of BusCo in Ireland’s public transport sector, the article enriches sociological understanding of trade union solidarity, and how it is engendered, contested and experienced.

Carbon Dioxide Co2

In this paper, we use the Logarithmic Mean Divisia Index (LMDI) to apply decomposition analysis on Carbon Dioxide (CO2) emissions from transport systems in seven Eastern European countries over the period between 2005 and 2015. The results show that “economic activity” is the main factor responsible for CO2 emissions in all the countries in our sample. The second factor causing increase in CO2 emissions is the “fuel mix” by type and mode of transport. Modal share and energy intensity affect the growth of CO2 emissions but in a less significant way. Finally, only the “population” and “emission coefficient” variables slowed the growth of these emissions in all the countries, except for Slovenia, where the population variable was found to be responsible for the increase in CO2 emissions. These results not only contribute to advancing the existing literature but also provide important policy recommendations.

BACKGROUND The NHS cannot keep up with the demand for operations and procedures. Preoperative assessments, which can last 30 minutes to 2 hours, could be conducted online to save patient and clinician time, reducing wait times for operations. MyPreOp is a cloud-based platform where patients can set up an account and complete their preoperative questionnaires. This data is reviewed by a nurse, who determines if they need a subsequent face-to-face appointment. OBJECTIVE The primary objective was to describe the potential impact of MyPreOp® (Ultramed Ltd, Penryn, UK) the number of face-to-face appointments. Secondary objectives were to examine the time spent on preoperative assessments completed using MyPreOp in everyday use in NHS Trusts and user ratings of usability and acceptability. METHODS A case study service evaluation of data collected by the MyPreOp system from two NHS Trusts (Guy’s and St Thomas’ and Royal United Hospitals Bath) and the private BMI Bath Clinic during the four-month period of September to December 2020. MyPreOp is delivered by the hospital conducting the preoperative assessment but is typically completed at home at the patients’ convenience. Participants were adults of any age and health status at the participating hospitals who used MyPreOp to complete a preoperative assessment before a scheduled surgery. The primary outcome was the number of face-to-face appointments avoided by patients who used MyPreOp. Secondary outcomes were the length of time spent by nurses completing preoperative assessments, associated travel-related CO2 emissions, and quantitative user feedback. RESULTS Data from 2,500 participants was included. Half of the patients assessed did not need a further face-to-face appointment and required a median of only 5.3 minutes of nurses’ time. The reduction in appointments was associated with a small saving of CO2e emissions (9.05 tonnes). Patient feedback was generally positive: 80% of respondents rated MyPreOp as easy or very easy to use and 85% thought the overall experience was good or very good. CONCLUSIONS This evaluation demonstrated potential benefits of MyPreOp. However, further research using rigorous scientific methodology and a larger sample of NHS Trusts and users is needed to provide strong evidence of MyPreOp’s efficacy, usability, and cost-effectiveness.
