During my internship at 15rock, I focused on researching sustainable investments, with a particular emphasis on pension funds. This area is critical as pension funds manage long-term assets that directly impact the financial security of millions of retirees. Incorporating sustainability into these investments not only mitigates risks associated with environmental, social, and governance (ESG) factors but also enhances long-term value creation. Understanding how sustainable investment strategies can align financial performance with positive societal impact is essential for building resilient pension portfolios in an evolving regulatory and market landscape.
