Several sources show that investors have an increased interest in sustainability, while others show the opposite and do not recommend moving favorable investments from companies with negative environmental impacts.Purpose: The purpose of this study is to increase the understanding of how much investment companies take sustainability into account when investing and how investment companies contribute to increasing sustainable work in their companies.Method: The essay uses a qualitative research method with three semi-structured interviews over the telephone.Conclusion: The results of the study show that all investment companies believe that sustainability plays a decisive role whether they want to invest in companies or not. The reason is that sustainability is a prerequisite for companies to survive in the long term and all investment companies want to find companies that can generate long-term value. All three investment companies have signed guidelines and frameworks that will help the companies to operate towards a sustainable environment and work climate and influence the companies to responsible investment. If any company owned by the investment companies violates the established guidelines, the investment companies may choose to terminate their ownership of the company.

Environmental, Social and Governance (ESG) data has been seen as a tool to implement Sustainability in investment companies. This non-financial data has brought along new type of information into the investment process, resulting in a profound transformation for companies. In order to adapt to the new realities of climate change and social challenges, companies must understand that changes in organization processes are essential to address the outcomes that ESG data will bring. Organizational changes are often caused by internal and external factors, allowing organizations to develop new processes and results that can influence the adoption of a new organizational culture approach. This study analyzes the essential organizational changes in terms of structure and culture. The authors used a multi-case study of two Asset management companies and an external group of experts to do so. The case analysis was conducted through a qualitative content analysis based on semi-structured interviews with nine employees and two external experts within the Asset Management industry. The study results show that ESG plays a vital role in organizational development, forcing structural changes and a new approach toward organizational culture in Asset Management companies.
