This paper explores the link between innovation and sustainability in the context of higher education, with the purpose of investigating the fundamental barriers for innovation and sustainable development in universities around the world. The method used involves both a quantitative and a qualitative approach, gathering the views of 301 experts from 172 universities across all continents. The results show that there are similar barriers across different geographical regions that require greater support from university administrations and management. In particular, the willingness of leaders, policy makers and decision-makers to envisage a sustainable future inside universities is often missing. Yet, without the support of senior management within a university, bottom-up sustainable initiatives seem destined to fail in the longer term due to a lack of investment and administrative support. This study also identifies that in order to yield the anticipated benefits, barriers need to be tackled in an integrated way, and that closer cooperation between sustainability researchers, university administrations and students is needed.

A review of the literature reveals the scant research on sustainable procurement in the public sector, and in particular higher education institutions. In this context, this paper aims to contribute to an emerging stream of research on drivers and challenges higher education institutions face in endorsing sustainable procurement practices. Crucially, the study seeks to shed light on critical barriers affecting the implementation of sustainable procurement at universities. Policy recommendations are presented and approaches on how to overcome barriers to sustainable procurement are set forth.

Purpose Sustainability has become a global concern to deal with complex and unprecedent survival, social, political and peace issues. Higher education institutions play a key role in this transformation. This paper aims to conduct a comparative analysis by continents of innovation and sustainability barriers in universities. The document also offers opportunities and potential actions for universities to create initiatives to minimize barriers and move towards a sustainable future. Design/methodology/approach To carry out the study, 25 closed questions, composed of a five-point Likert scale, were applied to 283 university representatives (rectors, managers or specialists in the area of innovation and sustainability), to check the degree of application of the questionnaire. Findings From an exploratory statistical analysis, it was found that the main barriers were lacking of planning and focus, lacking of environmental committee, lacking of applicability and continuity of actions and resistance to changes. Among continents, Africa and Oceania presented the best innovation and sustainability indicators in universities. The main approach of this exploratory study on barriers in universities is as an international research, whose findings showed that several barriers currently prevent universities from getting involved in sustainable development efforts. However, as we debate sustainable development, which is gaining momentum, universities are supposed to move forward to overcome barriers for the sake of implementing goals and initiatives. In addition, universities must seize opportunities to contribute through innovation in teaching, research and initiatives to achieve the 17 sustainable development goals. Research limitations/implications This study has two main limitations: first, online research has involved professionals working in the field of sustainable development in higher education. Second, there were no interviews conducted to gather personal information with students and servers. However, the broad scope of the study and its strong international base provide important results that enable the design of an adequate profile of sustainability and innovation challenges that are currently found in universities. Practical implications The study showed that there is lack of knowledge management to connect science, technology, innovation and sustainability, to improve management conditions, innovate, make decisions, support initiatives, create incentives and control mechanisms. Trends suggest that future professional activities involve skills in dealing with complex problems, sometimes in careers and jobs yet to be created. Traditional teaching methods are generally only prepared for routine tasks and for existing jobs, thus requiring the creation of new approaches capable of stimulating creativity and autonomy, which are essential for the present and future demands of innovation and sustainability. Social implications The exploratory study on barriers in universities brings international research as main approach, which made it possible to check that several barriers currently prevent universities from getting involved in sustainable development efforts. However, as we debate sustainable development, which is gaining momentum, it is important that universities should move forward to overcome the barriers to implementation of goals and initiatives. In addition, universities should take advantage of opportunities to contribute through innovation in teaching, research and action to achieve the 17 sustainable development goals. Originality/value Developed countries are leaders in promoting sustainability, while developing or underdeveloped countries are laggards. In this approach, the study sought to verify the differences through a comparative analysis across continents. As for originality and innovation, this paper presents an international study in the view of specialists who respond based on the experience of their university.

The apparel industry, which includes the clothing/garment sector, encompasses the supply chain of clothing and garments, starting with the textile and fashion industry, all the way to fashion retailers and the trade with second-hand clothes and textile recycling. This sector is characterized by substantial wastes, which may be minimized by means of textile recycling. This paper reports on the results of an international study on sustainable clothing consumption. This paper identifies and analyzes attitudes and behaviors regarding the clothing industry in a sample of 203 individuals. The results suggest a number of trends. Firstly, they show the complexity of purchase habits. The reasons why individuals dispose of their old or not used clothes are manifold, and include objective and subjective factors. Also, the paper illustrates the existence of disparities in respect of clothing use and disposal behavior. Finally, the results suggest that there is a need for more awareness-raising initiatives, in order to make consumers more conscious about the options available and the need for a more sustainable use of clothing.
