The World Health Organization has pointed to climate change as the most significant issue in the 21st century as a result of greenhouse gas emissions and environmental pollution. Organizations are leaning toward corporate social responsibility (CSR) and environmental management systems (EMS) to reverse the current trend; however, these efforts are often ineffective or pooly implemented. The purpose of this quantitative study was to determine the extent to which employees' proenvironmental behavior relates to their protection motivation and organizational identification, as well as their perception and knowledge of the organization's CSR and EMS, respectively. Using social identity as the theoretical framework, this research addressed how organizational and intrapersonal factors influence employees' proenvironmental behavior. One hundred-twenty employees from American-based organizations completed an online survey measuring self-assessed proenvironmental behaviors, among other variables. The results from a Pearson correlation analysis indicated that all of the independent variables had a significant positive relationship with employee proenvironmental behaviors. Multiple regression analysis showed that while each variable was a significant predictor of proenvironmental behaviors, only the economic dimension of CSR (β = .300, p = .014) and the self-efficacy dimension of protection motivation (β = .269, p = .037) significantly contributed to the model. Leaders' use of the findings may lead to positive social change through improved environmental performance in the form of decreased pollution, a more efficient use of natural resources, and reduced greenhouse gas emissions, all toward a more sustainable future.

The food choices we make every day have a great impact on our environment. Particularly meat consumption significantly contributes to global climate change. Although the current situation calls for a change towards more sustainable diet, meat consumption is still rising. Previous research show that dynamic social norms, i.e. information about ongoing collective behavioral change, can promote pro- environmental behavior, even in the context of meat consumption. Through two pre- registered online experimental studies conducted on a sample of university students (Study 1, N = 227) and on a sample of adult Czech population (Study 2, N = 462), this thesis examines whether dynamic norm message regarding the changing trends in meat consumption can influence intentions to consume less meat. We did not find any direct or total effect of dynamic norms on the preference for meatless meals. Mediation analysis only revealed rather weak indirect effect of dynamic norms on the preference for meatless meals mediated by perceived dynamic norms. In Study 2, we further examined whether the effect of dynamic norm message is conditioned by strength of the dynamic norms (effect of stronger vs weaker dynamic norm) and whether the provision of dynamic norm information triggers self-defense mechanisms which rationalize...

[ES] El Sistema agroalimentario es uno de los principales causantes del complejo entramado de problemáticas que conforman la actual crisis ecosocial, desde el cambio climático a la pérdida de biodiversidad, pasando por la disrupción de los ciclos biogeoquímicos, los cambios de uso del suelo, la contaminación o la sobre-explotación de los recursos hídricos. En el origen de estos graves desequilibrios ambientales subyacen unos estilos de vida alta y crecientemente demandantes de materiales y energía, completamente ajenos a los límites finitos del planeta en que habitamos. Hasta ahora, en el ámbito de la alimentación, el desarrollo de estrategias para minimizar la contrapartida ambiental al consumismo de una parte del mundo se ha centrado mayoritariamente en soluciones tecnológicas (por ejemplo, la reducción de la intensidad de las emisiones de la producción mediante diferentes manejos agronómicos). Sin embargo, son escasas las probabilidades de que este tipo de medidas sea suficiente para cubrir las necesidades mínimas de la población global sin poner en riesgo el equilibrio de los ecosistemas y la vida en el planeta Tierra. La adopción de hábitos alimentarios sostenibles es una medida potencialmente al alcance de todas las personas, no solamente asociada a la reducción de la presión ambiental, sino también a una mejor salud humana. No obstante, pese a la creciente toma de conciencia social sobre las implicaciones de la alimentación sobre la salud humana y planetaria, las intenciones personales de mejorar los hábitos alimentarios se ven frustradas por la existencia de múltiples barreras de muy diversa índole. Por ello, y dada la urgencia de la situación en que nos encontramos, resulta necesaria la implementación de intervenciones que impulsen cambios a gran escala. Esta Tesis Doctoral pretende contribuir a mejorar el conocimiento sobre cómo los hábitos alimentarios sostenibles - focalizando en dietas ricas en productos vegetales y productos ecológicos, locales y de temporada - pueden ser impulsados y facilitados. Para ello, se emplea un enfoque transdisciplinar, explorando tres estrategias diferentes. En un primer lugar se analiza el potencial mitigador del cambio climático de los huertos urbanos, mediante su función de catalización de hábitos alimentarios sostenibles y la reducción de la huella de carbono de las personas que interactúan en este tipo de espacios. En segundo lugar, se realiza una segmentación de audiencias respecto a varios criterios de sostenibilidad ambiental y determinantes psico-sociales del consumo alimentario correspondientes a varios niveles cognitivos. Por último, se describe el proceso de diseño de una aplicación móvil para facilitar la adopción de hábitos alimentarios sostenibles y saludables, en la que se han integrado conocimientos de las ciencias sociales y naturales. La Tesis se presenta en formato de compendio de artículos. El primero de los capítulos corresponde a un artículo publicado en una revista de alto impacto (D1). Por otro lado, esta Tesis se ha desarrollado en el marco del programa de Doctorados Industriales de la Agencia Española de Investigación, con referencia DIN2018-009975. El desarrollo experimental ha sido realizado en la empresa ICATALIST, S.L., y corresponde al diseño de la aplicación móvil descrita en el capítulo 4. / [CA] El Sistema agroalimentari és un dels principals causants del complex entramat de problemàtiques que conformen l'actual crisi ecosocial, des del canvi climàtic a la pèrdua de biodiversitat, passant per la disrupció dels cicles biogeoquímics, els canvis d'ús del sòl, la contaminació o la sobre-explotació dels recursos hídrics. En l'origen d'estos greus desequilibris ambientals subjauen uns estils de vida alta i creixentment demandants de materials i energia, completament aliens als límits finits del planeta en què habitem. Fins ara, en l'àmbit de l'alimentació, el desenvolupament d'estratègies per a minimitzar la contrapartida ambiental al consumisme d'una part del món s'ha centrat majoritàriament en solucions tecnològiques (per exemple, la reducció de la intensitat de les emissions de la producció mitjançant diferents manejos agronòmics). No obstant això, són escasses les probabilitats que este tipus de mesures siga suficient per a cobrir les necessitats mínimes de la població global sense posar en risc l'equilibri dels ecosistemes i la vida en el planeta Terra. L'adopció d'hàbits alimentaris sostenibles és una mesura potencialment a l'abast de totes les persones, no solament associada a la reducció de la pressió ambiental, sinó també a una millor salut humana. No obstant això, malgrat la creixent presa de consciència social sobre les implicacions de l'alimentació sobre la salut humana i planetària, les intencions personals de millorar els hàbits alimentaris es veuen frustrades per l'existència de múltiples barreres de molt diversa índole. Per això, i donada la urgència de la situació en què ens trobem, resulta necessària la implementació d'intervencions que impulsen canvis a gran escala. Esta Tesi Doctoral pretén contribuir a millorar el coneixement sobre com els hàbits alimentaris sostenibles - focalitzant en dietes riques en productes vegetals i productes ecològics, locals i de temporada - poden ser impulsats i facilitats. Per a això, s'empra un enfocament transdisciplinar, explorant tres estratègies diferents. En un primer lloc s'analitza el potencial mitigador del canvi climàtic dels horts urbans, mitjançant la seua funció de *catalización d'hàbits alimentaris sostenibles i la reducció de la petjada de carboni de les persones que interactuen en esta mena d'espais. En segon lloc, es realitza una segmentació d'audiències respecte a diversos criteris de sostenibilitat ambiental i determinants psicosocials del consum alimentari corresponents a diversos nivells cognitius. Finalment, es descriu el procés de disseny d'una aplicació mòbil per a facilitar l'adopció d'hàbits alimentaris sostenibles i saludables, en la qual s'han integrat coneixements de les ciències socials i naturals. La Tesi es presenta en format de compendi d'articles. El primer dels capítols correspon a un article publicat en una revista d'alt impacte (D1). D'altra banda, esta Tesi s'ha desenvolupat en el marc del programa de Doctorats Industrials de l'Agència Espanyola d'Investigació, amb referència DIN2018-009975. El desenvolupament experimental ha sigut realitzat en l'empresa *ICATALIST, S.L., i correspon al disseny de l'aplicació mòbil descrita en el capítol 4. / [EN] The agri-food system is one of the main causes of the complex and tangling problems that make up the current eco-social crisis, from climate change to biodiversity decline, including the disruption of biogeochemical cycles, changes in land use, pollution or the over-exploitation of water resources. At the origin of these serious environmental disturbances lie the expansion of lifestyles that are highly and increasingly demanding of materials and energy, completely unconnected to the finite limits of the planet we inhabit. Until now, in the food domain, the development of strategies to minimize the environmental repercussions of consumerism in one part of the world has mainly focused on technological solutions (for example, the intensity reduction of production emissions through different agronomic management techniques). However, the chances that these types of measures will be sufficient to cover the minimum needs of the global population without putting at risk ecosystems' balance and life on planet Earth are low. The adoption of sustainable eating habits is a measure potentially within the reach of all people, not only associated with the reduction of environmental pressure but also with better human health. However, despite the growing social awareness of the implications of diet on human and planetary health, personal intentions to improve eating habits can be frustrated by the existence of multiple barriers of very diverse kinds. For this reason, and given the urgency of mitigating current environmental problems, the implementation of interventions that promote large-scale changes is necessary. This Doctoral Thesis aims to increase existing knowledge about how the adoption of sustainable eating habits - focusing on plant-rich diets based on organic, local, and seasonal products - can be promoted and eased. To do this, a transdisciplinary approach is used, exploring three different methodologies. First, the climate change mitigating potential of urban gardens is analysed, through the catalysing of sustainable eating habits and reducing the carbon footprint of the people who interact in these types. Secondly, a segmentation of audiences is carried out with a multi-criteria sustainability scope and psychosocial determinants of food consumption corresponding to various cognitive levels. Finally, the design process of a mobile application to facilitate the adoption of sustainable and healthy eating habits is described, in which knowledge from social and natural sciences has been integrated. The Thesis is presented in the format of a compendium of articles. The first chapter corresponds to an article published in a high-impact journal (D1). On the other hand, this Thesis has been developed within the framework of the Industrial Doctorate program of the Spanish Research Agency, with reference DIN2018-009975. The experimental development has been carried out in the company ICATALIST, S.L., and corresponds to the design of the mobile application described in Chapter 4. / This thesis has been developed within the framework of the Industrial Doctorate program of the Spanish Research Agency, with reference DIN2018-009975. / Puigdueta Bartolomé, I.

所謂都市服務設施係指「提供社會、文化、經濟、政治與宗教等服務機能之都市設施」。但由於都市服務設施的種類與使用性質的不同，對都市環境或生活品質也產生不同的影響，有些對環境有正面的「迎毗」效果，有些卻會產生負面的「鄰避」效果，而有些則是迎毗效果與鄰避效果同時存在。 　　以往有關鄰避效果的研究，無論是國內外多只是就個案或是某類設施進行探討，在界定迎毗效果與鄰避效果時也過於主觀，因而對具有鄰避效果之設施的探討未盡完整。因此本研究運用環境行為的研究方法，以台北地方生活圈為研究範圍，自居民的接受意願與鄰避指數來界定鄰避效果，並尋求都市居民為何會對都市服務設施產生鄰避的心理或行為，以及影響鄰避的因素，最後驗證本研究所建立的都市服務設施鄰避效果之概念模式。 　　根據研究成果所獲得的結論與建議如下： 　　一、本研究所建立的「都市服務設施鄰避效果」概念模式有資訊、動機、環境態度、經驗、個人屬性、與都市階層等六個概念因子，而中介因子為接受意願。 　　二、根據都市居民的接受意願可以將都市服務設施劃分為「不願意接受」、「接受意願態度混雜」、與「願意接受」三個層級；而以鄰避指數度量鄰避效果，則可發現都市服務設施的鄰避效果依輕重程度可以劃分為四個等級：「不具鄰避效果」、「輕度鄰避效果」、「中度鄰避效果」、與「高度鄰避效果」。 　　三、大多數的環境認知與態度不會因受訪者所在的都市階層不同而受影響。而將環境認知與態度經因子分析操作後，各都市階層抽出的因子結構不甚相同，經調整後可得出四個影響都市服務設施接受意願的因子，分別是資訊、環境態度、動機、與經驗。此外，檢驗概念模式中的概念因子與接受意願的互動關係，發現除了經驗與都市階層二個因子與研究假設一致，其餘三個都與假設有所差異。 　　四、策略建議方面：建議從法規面、規劃者角色定位、土地使用規劃、及都市服務設施管理方面考慮改善鄰避效果之策略。 / Urban service facilities are those that provide "social, cultural, economic, political, and religious functions." Due to different types and functions, these facilities will have varied impacts on environment. Some are positive, and hence "YIMBY" (Yes-ln-My-Back-Yard) facilities; some are negative, and hence "NIMBY" (Not-ln-My-Back-Yard) facilities; some have both effects. 　　Previous studies dealing with NIMBY effects were mostly case studies or studies that focused on certain types of facilities. In addition, most previous studies were based on subjective concepts to define NIMBY effects. Therefore, this thesis adopts Environment-Behavior research method to study NIMBY effects of urban service facilities in Taipei area. Using the "willingness-to-accept" concept and the "NIMBY indicator," this thesis defines NIMBY effects of urban service facilities. This thesis also seeks to explore why citizens demonstrate NIMBY syndrome, and what factors affect NIMBY syndrome. The conceptual model of NIMBY effects is verified as well. 　　The conclusion and suggests are as follows: 　　1. The conceptual model of "NIMBY effects urban service facilities" consists of information, motivation, environmental attitudes, experience, personal attributes, and urban hierarchy. The intervening factor is the willingness to accept. 　　2. According to the willingness to accept, urban service facilities can be categorized as "not-willing-to-accept," "mixed attitudes," and "willing-to-accept." Using the NIMBY indicator concept to measure NIMBY effects, NIMBY effects can be classified as "no NIMBY effects," "small NIMBY effects," "moderate NIMBY effects," and "serious NIMBY effects." 　　3. Most environmental attitudes will not vary in different urban hierarchies. The results of factor structures of environmental attitudes are varied in different urban hierarchies. After adjustment, four factors influencing the willingness to accept urban service facilities can be extracted: information, environmental attitudes, motivation, and experience. In addition, in examining the relationships between the conceptual model and the willingness to accept, only experience and hierarchies are consistent with our hypotheses. 　　4. This thesis suggests four possible directions to mitigate NIMBY effects and the NIMBY syndrome: regulations, planners' roles, land use planning, and urban facility management.
