M. Tech. Marketing / The focus of this study is on the determinants of positive green-product purchase behaviour of Tshwane youth. Environmental knowledge, environmental concern, social pressure and green-product purchase intentions were identified as determinants of positive green-product purchase behaviour and investigated among a sample of Tshwane youth alongside their green-product purchase behaviour. The differences between the various demographic groups with regard to their positive green-product purchase behaviour were also investigated.

Thesis (MBA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Greenwashing is a growing concern globally. The increase in the number of green-marketed products has resulted in an increase in greenwashing. Some companies market their products as green, while they are not. They then respond with greenwashing to neutralise condemnations from environmental laws and government or to gain competitive advantage. Investigations into the existence of greenwashing in developed countries have shown high percentages. This study was therefore aimed at investigating the magnitude of greenwashing in South African products and determining whether there is a similar trend to other investigated countries. This research study was conducted among six South African magazines, which have different target markets and therefore advertise different product categories. The results indicated that 94 percent of green-advertised products in South Africa were greenwashing. Baby products and cosmetic products had the highest percentage of green-advertised products and greenwashing products. Amongst the sins of greenwashing, which were used to analyse the greenness of the products, the sins of ‘vagueness’ and ‘no proof’ had the highest percentages and were evident in all product categories. The study also determined which target market was most susceptible to greenwashing. The results show that new mothers were more likely to buy green products, followed by women in general. The green claims that showed evidence of highest presence in South African products were BPA-free, Natural, Organic and Pure.

M. Tech. (Department of Logistics Management, Faculty of Management Sciences), Vaal University of Technology. / In South Africa, the beverage industry is perceived to be a major contributor to the economy. Internal and external stakeholders in this industry are engaged in environmental collaboration with each other to achieve better environmental and supply chain performance. The aim of this study was to investigate the influence of green supply chain management practices on environmental performance and supply chain performance in the beverage industry of South Africa. It considers four of these practices, namely, internal environment management, investment recovery, eco-design and green purchasing. A quantitative approach was adopted, with the use of a survey questionnaire to collect information from 373 supply chain management professionals from beverage companies in South Africa. The study used a probability simple random sampling method. The data gathered was analysed using the Statistical Package for the Social Sciences (SPSS) version 25.0 and Analysis of a Moment Structures (AMOS) version 25.0. A Confirmatory Factor Analysis (CFA) was used to validate the measurement scales while Structural Equation Modelling (SEM) was applied to test the relations between constructs. The results revealed that internal environment management, investment recovery, eco-design and green purchasing positively and significantly influence environmental performance. Moreover, the results also revealed that environmental performance exerted a strong, significant and positive influence on supply chain performance. Recommendations and implications for further research were made based on these results. The study presents supply chain management professionals, internal and external stakeholders within the beverage industry with useful insights on key factors that ought to be addressed in order to improve their organisational strategies. Therefore, the study is essential to internal and external stakeholders in the beverage industry who wish to improve environmental and supply chain performance.
