With more cities aiming to achieve climate neutrality, identifying the funding to support these plans is essential. The purpose of this paper is to exploit the present of a structured green bonds framework in Sweden to investigate the typology of abatement projects Swedish municipalities invested in and understand their effectiveness.

Marginal abatement cost curves of the green bond measures are constructed by using the financial and abatement data provided by municipalities on an annual basis.

The results highlight the economic competitiveness of clean energy production, measured in abatement potential per unit of currency, even when compared to other emerging technologies that have attracted the interest of policymakers. A comparison with previous studies on the cost efficiency of carbon capture storage reveals that clean energy projects, especially wind energy production, can contribute to the reduction of emissions in a more efficient way. The Swedish carbon tax is a good incentive tool for investments in clean energy projects.

The improvement concerning previous applications is twofold: the authors expand the financial considerations to include the whole life-cycle costs, and the authors consider all the greenhouse gases. This research constitutes a prime in using financial and environmental data produced by local governments to assess the effectiveness of their environmental measures.

The purpose of this study is to identify crucial sustainability assessment criteria in the context of international port sector.

Data collection was based on a questionnaire survey from 135 managers and supervisors at major international ports in Taiwan, including Keelung, Taichung and Kaohsiung. A confirmatory factor analysis was conducted to identify crucial sustainability assessment criteria at ports.

A total of 31 important sustainable assessment criteria were adapted from previous studies in terms of environmental, economic and social issues. Results revealed that social issues with respect to staff job security and safety were ranked as the most important sustainability assessment criteria, followed by environmental protection when handling cargo, facilitation of economic activities, port traffic accidents prevention and cargo handled safely and effectively. In contrary, respondents revealed their less importance in the criteria, namely, mitigating light influence on neighboring residents, considering the arrangement of vehicles when constructing port transportation system, avoiding using unpolluted land in port area and hiring minority groups and consulting interests groups when making port projects. Four sustainability assessment dimensions were identified, namely, environmental material, economic issue, environmental practices and social concerns.

The research findings indicated that economic issue was deemed as the most important dimension of sustainability assessment criteria from a port operator’s perspective, followed by environmental practices, social concerns and environmental material. Practical implications for port sustainability assessment were discussed in this research.

Although a majority of previous studies on sustainability assessment have been discussed, there is still a lack of investigation of sustainability assessment in the context of port sector. This study not only develops sustainability assessment attributes but also highlights the important criteria of sustainability assessment. Further, this study identified four crucial sustainability assessment factors, which provide helpful information for port corporations to identify important criteria and policy of sustainability assessment.

As of January 1, 2020, the upper limit of sulfur emissions outside emission control areas decreased from 3.5% to 0.5%. This paper aims to present some of the challenges associated with the implementation of the sulfur cap and investigates its possible side effects as regard the drive of the International Maritime Organization (IMO) to reduce carbon dioxide (CO₂) emissions. Even though it would appear that the two issues (desulfurization and decarbonization) are unrelated, it turns out that there are important cross-linkages between them, which have not been examined, at least by the regulators.

A literature review and a qualitative risk assessment of possible CO₂ contributors are presented first. A cost-benefit analysis is then conducted on a specific case study, so as to assess the financial, as well as the environmental impact of two main compliance choices, in terms of CO₂ and sulfur oxide.

From a financial perspective, the choice of a scrubber ranks better comparing to a marine gas oil (MGO) choice because of the price difference between MGO and heavy fuel oil. However, and under different price scenarios, the scrubber choice remains sustainable only for big vessels. It is noticed that small containerships cannot outweigh the capital cost of a scrubber investment and are more sensitive in different fuel price scenarios. From an environmental perspective, scrubber ranks better than MGO in the assessment of overall emissions.

Fuel price data in this paper was based on 2019 data. As this paper was being written, the COVID-19 pandemic created a significant upheaval in global trade flows, cargo demand and fuel prices. This made any attempt to perform even a rudimentary ex-post evaluation of the 2020 sulfur cap virtually impossible. Due to limited data, such an evaluation would be extremely difficult even under normal circumstances. This paper nevertheless made a brief analysis to investigate possible COVID-19 impacts.

The main implication is that the global sulfur cap will increase CO₂ emissions. In that sense, this should be factored in the IMO greenhouse gas discussion.

According to the knowledge of the authors, no analysis examining the impact of the 2020 sulfur cap on CO₂ emissions has yet been conducted in the scientific literature.

Prefabricated products are continually entering the building construction market; yet, the decision to use prefabricated products in a construction project is based mostly on personal preferences and the evaluation of direct costs. Researchers and practitioners have debated appropriate measurement systems for evaluating the impacts of prefabricated products and for comparing them with conventional on-site construction practices. The more advanced, cost–benefit approach to evaluating prefabricated products often inspires controversy because it may generate inaccurate results when converting non-monetary effects into costs. As prefabrication may affect multiple organisations and product subsystems, the method used to decide on production methods should consider multiple direct and indirect impacts, including nonmonetary ones. Thus, this study aims to develop a multi-criteria method to evaluate both the monetary and non-monetary impacts of prefabrication solutions to facilitate decision-making on whether to use prefabricated products.

Drawing upon a literature review, this research suggests a multi-criteria method that combines the choosing-by-advantage approach with a cost–benefit analysis. The method was presented for validation in focus group discussions and tested in a case involving a prefabricated bathroom.

The analysis indicates that the method helps a project’s stakeholders communicate about the relative merits of prefabrication and conventional construction while facilitating the final decision of whether to use prefabrication.

This research contributes a method of evaluating the monetary and non-monetary impacts of prefabricated products. The research underlines the need to evaluate the diverse benefits and sacrifices that stakeholder face when considering production methods in construction.

A boom in e-commerce in Korea has sparked off high daily-volume demand for small-sized home delivery services, which poses a great challenge to distribution networks, especially in urban areas where traffic congestion, accessibility, and pollution are serious problems. In addition, security issues for people who live in small townhouses and detached houses without security systems and guards have received increasing attention from the government and society. Thus, the introduction of a new alternative for home delivery services, unmanned parcel lockers, is urgent for residents living in these areas. This paper examines and compares potential socio-economic impacts in terms of costs and benefits when such lockers are installed at selected locations in residential areas. The results show that this policy is worthy of adoption, with several undeniable benefits to local communities. In addition, sensitivity analyses estimate the economic performance of this project at different social discount rates, and they check the sensitivity of economic performance based on variations in the variables. The value of travel time savings was identified as a critical and dominating factor directly affecting economic performance.

This study examined Taiwan's fiscal policy responses for sustainable post-COVID-19 recovery. The costs and benefits, aligned with Sustainable Development Goals (SDGs), of fiscal policy responses were identified and valued. Although it may be too early to conclude whether the benefits outweigh the costs, the performance and outcome of fiscal measures were evaluated.

The study relied on secondary data, including governmental official data, legislative reviews, audit reports and public opinion polls to understand objective and subjective benefits and costs in economic, social and environmental dimensions. However, while the costs were measured in monetary terms, some of the benefits (i.e. satisfaction) could not be monetized; therefore, this study focused on identifying and valuing benefits from fiscal measures but set aside the issues of monetizing and discounting.

With respect to the costs, a special budget of NT$840 billion was approved, of which 66.83% was allocated for economic development, 33.12% for social welfare and 0.05% for environmental protection. In terms of the benefits, the economic growth rate was forecasted to be 5.88% in 2021 and 3.69% in 2022, while the average economic growth rate was 2.77% during the period from 2012 to 2019. Social equity was emphasized as various and customized bailout packages were provided to impacted individuals and industries. Moreover, most citizens were confident in the government's efforts to combat the pandemic and stimulate recovery in Taiwan.

This paper comprehensively details Taiwan's experience of fiscal policy responses for sustainable post-COVID-19 recovery. The cost-benefit approach was conceptually adopted. Bearing the value of “build back better” and “rebuild better,” the benefits of fiscal measures are promising, although there are indebted costs of the special budget.

The geographic information systems (GIS) sector is witnessing significant growth in recent times at the global level and in the Kingdom of Saudi Arabia at the same pace. In this research, the authors aim to measure the GIS market employability in the Kingdom of Saudi Arabia, the required skills of those seeking GIS employees, existing knowledge and abilities of graduates of relevant academic programs and gaps, if any, between the graduates and the labor market requirements in terms of GIS. Research on GIS education and GIS employability from an information system perspective is scarce; thus, this study is needed.

In this study, a questionnaire was distributed manually and electronically to a specific group of GIS students, teachers and employees. The questionnaire was prepared in Arabic and English language. It was distributed manually to the attendees of the 12th GIS Symposium, organized by Imam Abdulrahman Bin Faisal University at Dammam city, Saudi Arabia in April of 2018. The event is a yearly one that gathers local GIS community and outside speakers and guests. An electronic version of the questionnaire was also available and distributed via personal contacts. Responses were received until the end of 2019.

The results of 107 respondents indicates good GIS foundation (for example in topology, geospatial data processing and cartography); however, programming and business skills (namely cost benefit analysis, organizational perspective and business understanding) are lacking from Saudi GIS graduates. About 67% of respondents acknowledge directly that it is difficult to find locally qualified GIS graduates. Moreover, 55% of respondents classify GIS job candidates as underqualified. This research identifies under qualification in business competencies and computer programming skills for GIS students and workers in Saudi Arabia. This research did not find a statistically significant different response between GIS teachers and GIS employees/employers; however, students’ response was significantly different from these two groups.

Research on GIS education and GIS employability from an Information System perspective is scarce; thus, this study is needed. Moreover, research about this topic in Saudi Arabia and the Arabian Gulf is almost nonexistent.
