E-commerce has grown continuously in recent years;in fact,e-commerce in Germany surged from 1.1 billion Euros in 1999 to 57.8 billion Euros in 2019.As a result,the packaging and shipment volume also increases by several billion per year.However,with this increase,the amount of waste has also grown;this packaging waste results in an accelerated burden to the environment.Companies are using CSR strategies to develop modern packaging that is both functional and environmentally friendly.Corporate social responsibility and sustainability are currently the popular terms in the corporate industry world where organizations are trying to fulfil their role towards society and the environment.Especially for e-commerce businesses,it is a significant step to shift their packaging to more sustainable packaging,which is reusable and also doesn’t have adverse effects on the environment.The focus on sustainability and packaging is often on reducing the used materials.However,this does not always have to be the ideal solution.Optimizing,as well as designing the packaging content and focusing on the right message with regard to the sustainability aspects of the company,can also lead to a good result.Many companies assume social,environmental and societal responsibility.More and more companies see sustainability as a differentiator to differentiate themselves from competitors in the market.In this way,companies save a lot of money and gain a competitive advantage.Some companies are publicly committed to sustainable issues and report on their social and environmental measures.More than ever,consumers want transparency in corporate social responsibility communication.This thesis aims to discuss the viability of using sustainable packaging by e-commerce organizations and how it can help in achieving the company’s social responsibility.Corporate responsibility for the environment and society is a very complex and multifaceted topic,which does not make it easy for companies to meet all stakeholders and requirements and to act economically successfully at the same time.Sustainability reports and CSR have become part of a successful corporate strategy today.The packaging also fulfills critical protective functions and ensures that products reach us safely.Today’s modern packaging has to perform many essential functions,survive long transport routes,and at the same time,it is the most crucial communicator between trade and client.The packaging is a vital decision criterion when buying a product.During the interview,the researcher tries to examine the companies’ understanding of the terms CSR,sustainability and circular economy will also be discussed.Furthermore,hurdles,advantages and possible solutions for companies are to be identified in order to integrate sustainability into package development.Ultimately,it should be examined whether companies succeed in incorporating sustainable design criteria into their circular economy of package development and whether there are differences between the approaches of sustainable packaging among our three target companies.The goal is to work out success factors for the integration of sustainability in package development and to find measures to reduce packaging waste.In order to achieve the research goals,this thesis will first analyse the literature and background information that can be gathered from secondary sources such as journals,books,websites etc.;the literature focuses on the topic of life cycle assessment,circular economy and the design of the packaging.Next,in chapters four and five will utilize the knowledge of the literature and the data to critically analyse the performance and adaptation of sustainable packaging by various organizations and consumers.Additionally,in Chapter 3,the thesis talks about the research methodology that is being used.The interviews with the three most prominent ecommerce organizations in Germany would be the base for the research.After utilizing this data,findings will be explored,and some methods to help lessen the loopholes will be presented.The present research is subject to qualitative research,which serves to depict reallife environments and in which the structural phenomena of social reality are determined.The focus and goal of this research are to do an in-depth case analysis of how these three ecommerce companies can achieve their CSR goals by incorporating sustainable packaging in their process.To answer this research question,we chose to make use of expert-interviews and case studies,which is based on small sample observations and a thorough analysis that can provide the researcher with necessary details to address the research questions.In chapter 4,this study will summarize,compare and list the findings from our interviews.These Interviews will help us answer our research question in how sustainable packaging and CSR are related to each other,and the potential benefits in following these practices will be shown.We will compare similarities and differences,and we will also focus on difficulties and other vital data that is being provided.Our interview helped us to understand how each firm defines and distinguishes the circular economy towards sustainable packaging.Furthermore,we could uncover the packaging design process of our three e-commerce giants and what decision they take into consideration in this endeavour.Chapter 5 is focusing on the analysis and discussion part of our findings;it also comes with recommendation on how further to improve the optimization of the packaging such as communication,creating an ecosystem and collaborating with NGOs and other government institutions and also implementing new technologies into the planning and construction of new kinds of packaging such as making more use of big data,machine learning and other technologies to make the packaging efforts smarter.Finally,we also share the limitations of our research and also give suggestion for further research and outlooks to improve the sustainability efforts of companies.
