What are the facts that affect the green investment funds and green entrepreneurship?

Purpose Green investment funds are still imperative in clarifying the fundamental components of their relationship to sustainability. This study aims to investigate the impact of different factors, such as green product design and innovation, green product entry barriers and green environmental awareness, on the success of green investment funds projects to finance environmentally friendly products. The research also investigates how green investment funds facilitate these factors to encourage environmentally sustainable business. Design/methodology/approach This paper used a questionnaire to collect insights from 210 green entrepreneurs in Asia, Africa, Europe and America. The data were then investigated using statistical tools, such as quantitative analysis of green entrepreneur surveys collected from various industries. The relationship between green product design and innovation, barriers to entry, environmental awareness and green entrepreneurship performance was investigated using partial least squares structural equation modelling, with green investment funds as a mediator. Findings The results indicate that every construct/variable included in the study supported the success of the sustainable business. The observation was made that the development phase tends to diminish the positive relationship between the success of green investment funds and green product codesign strategies. Implementing green product design and innovation improves the success of a green firm. Also, the progress of such companies might be hindered by entry barriers, and corporate performance is improved by environmentalism. This study found the role of green investment funds in promoting product innovation and positive environmental outcomes while reducing barriers to entry. Significance of the study Given these results, this work provides a theoretical explanation. Also, it gives doable recommendations for more successful green investment funds of environmentally friendly goods. The analysis emphasises the need for green product innovation and investment funds to mitigate entry obstacles. Corporate entities, investors and lawmakers receive pragmatic guidance on sustainable business practices. Originality/value This research, unique because of its multidisciplinary methodology and theoretical advances, examines the relationship between business, finance and sustainability. It provides valuable insights for academics, professionals and decision-makers, enhancing the understanding of green investment and entrepreneurship and offering practical global sustainable economic growth strategies. This paper investigates the impact of green investment funds on product innovation, entry obstacles, environmental consciousness and the success of green entrepreneurs. To the best of the author’s knowledge, this study is one of the limited numbers that models these features, enhancing the precision of green project success information.
