Transportation Sustainability on Economic and Environmental Aspects in the United States: Statistical and Quantitative Approaches

Choi, Jaesung January 2015 (has links)
The dissertation consists of three essays: 1) Productivity growth in the transportation industries in the United States: An application of the DEA Malmquist productivity index; 2) how does a carbon dioxide emissions change affect transportation productivity? A case study of the U.S. transportation sector from 2002 to 2011; and 3) forecast of CO2 emissions from the U.S. transportation sector: Estimation from a double exponential smoothing model. The first essay reviews productivity growth in the five major transportation industries in the United States (airline, truck, rail, pipeline, and water) and the pooled transportation industry from 2004 to 2011. The major findings are that the U.S. transportation industry shows strong and positive productivity growth except in the years of the global financial crisis in 2007, 2008, and 2010, and among the five transportation industries, the rail and water sectors show the highest productivity growth in 2011. The second essay examines the effects of a carbon dioxide (CO2) emissions change on actual productivity in the U.S. transportation sector. This study finds that a CO2 emissions increase from 2002 to 2007 had a negative effect on actual productivity in the U.S. transportation sector, but the CO2 emissions reduction for 2008–2011 increases actual productivity. States mainly showing sustainable growth patterns (decrease in CO2 emissions concurrent with increasing actual productivity) experience higher technological innovation increase than an efficiency decrease. This finding suggests that fuel-efficient and carbon reduction technologies as well as alternative transportation energy sources may be essential factors to both grow transportation and slow global warming. The third essay reviews whether the decreasing trend in U.S. CO2 emissions from the transportation sector since the end of the 2000s is consistent across all states in the nation for 2012‒2021. A double exponential smoothing model is used to forecast CO2 emissions for the transportation sector in the 50 states and the U.S., and its findings are supported by pseudo out-of-sample forecasts validity testing. This study concludes that the decreasing trend in transportation CO2 emissions in the U.S. will continue in most states in the future. / Mountain Plains Consortium (MPC) / U.S. Department of Transportation (USDOT)

Creating a 'Green University'.

Singh, Nisha. January 2010 (has links)
Evaluating the environmental performance of a university is important in order to identify more sustainable options for reducing the environmental footprints. The study was conducted at the University of KwaZulu-Natal (UKZN). The aim of the study was to assess the current greening status at UKZN, and then evaluate staff support to facilitate greening. The objectives of this study were to determine the current greening initiatives by staff and the university, staff support for greening and whether there were demographic differences in attitudes towards greening. The questionnaire was designed to obtain demographic information about the respondents, whether or not they contributed to greening, the nature of their contributions, reasons for apathy and suggestions to facilitate greening. Staff were also asked about current and possible future modes of transportation to the workplace, and about extending the computer replacement period. Seeing as no previous greening studies were conducted at UKZN, it was decided to obtain information from as many staff members as possible, through a web-based survey using the on-line software programme QuestionPro. Greening was considered to be important by the majority (97%) of the survey respondents, but only 67% of them actually contributed towards greening UKZN. In this respect, switching off lights was most practised (14.7%), followed by switching off computers after work (12.9%) and writing notes of scrap pieces on paper (12.3%). Other greening practices in order of popularity included the collection of used paper for re-cycling, the reporting of leaking taps, printing on both sides of the paper, and returning printer cartridges. Least selected greening practises were printing of the final copy only, indigenous gardening and animal care. There were numerous suggestions which covered mechanisms to save electricity, paper, and water, to facilitate greening at UKZN. The pursuit of management support and an established strategic environmental plan to steer and guide greening at UKZN, was considered urgent. The importance of awareness campaigns, better communication and facilitated recycling were emphasized. The vast majority of the staff (79.2%) travelled to work by means of their own transportation. Sharing of transport occurred in 11.6% of the sample. Public transportation, walking and cycling were used less frequently. Overall, the staff regarded intensified re-cycling, awareness and teaching programmes and the election of a dedicated team to manage greening projects as priority. / Thesis (MBA)-University of KwaZulu-Natal, Westville, 2010.

Les déterminants de l'intention environnementale des dirigeants des PME : Cas de l'industrie du textile-habillement tunisienne / Determinants of environmental intention of SMEs : The case of tunisian textile-clothing industries

Gribaa, Fafani 10 January 2013 (has links)
Devant l'accroissement des problèmes environnementaux menaçant la vie humaine, la question de l'implication de toute l'humanité dans la protection de l'environnement est aujourd'hui fortement mise en avant. Sur le plan managérial, les recherches académiques insistent, ces dernières années, sur la nécessité du changement des visions, des valeurs, des attitudes, des intentions et des comportements menant vers une organisation écologique. En positionnant notre recherche dans le champ de la psychologie du développement durable, l'objet de cette thèse est de développer un modèle expliquant les antécédents de l'intention environnementale des dirigeants des PME industrielles. Ainsi, en se basant sur la théorie du comportement planifiée et sur l'orientation entrepreneuriale, nous proposons un modèle conceptuel présentant l'influence des variables contextuelles (politiques, socioculturels et économiques) et individuelles (caractéristiques personnelles) sur la formation de l'intention environnementale des dirigeants des PME. La démarche empirique s'apparente à une démarche de triangulation méthodologique. Elle consiste en une étude qualitative exploratoire au prés de vingt dirigeants de PME, suivie d'une deuxième étude qualitative au prés de dix experts en développement durable et en RSE. Enfin, une étude quantitative au prés de 226 dirigeants est destinée à valider le modèle de recherche. Les résultats obtenus sont très intéressants et originaux. Ils montrent que les intentions environnementales des dirigeants ne résultent pas des pressions des parties prenantes. Par contre, l'intention est le résultat des perceptions de la disponibilité des ressources financières et de l'accompagnement, des résultats espérés du comportement souhaité vis-à-vis du pouvoir public et des institutions financières et aussi des caractéristiques personnelles du dirigeant (son degré d'innovation et de prise de risque). / In front of the increasing environmental problems that threaten human life, the question of the involvement of all mankind in the protection of the environment is strongly emphasized. At the managerial level and in the recent years, academic researchers have emphasized the need to change perceptions, values, attitudes, intentions and behavior leading to an environmental organization.By placing our research in the field of psychology of sustainable development, the subject of this thesis is to develop a model explaining the history of environmental leadership for industrial SMEs. Thus, based on the theory of planned behavior and entrepreneurial orientation, we propose a conceptual model showing the impact of contextual (political, cultural and economic) and individual variables (personal characteristics) on the formation of the environmental intention of SMEs managers.The empirical approach is similar to a process of methodological triangulation. It consists in a qualitative exploratory study nearly twenty SME, followed by a second qualitative study almost ten experts in sustainable development and CSR. Finally, a quantitative study in nearly 226 leaders is used to validate the research model. The results are very interesting and original. They show that environmental intentions of leaders are not the result of pressure from stakeholders. By contrast, the intention is the result of perceptions of the availability of financial resources and support, the expected results of the desired behavior concerning the public and financial institutions as well as personal characteristics of the leader (his degree of innovation and risk-taking).
