8.2 Motivation for Sustainable Investments
While positive contribution towards sustainable development may be seen as a benefit of investments itself, impact investing still remains a niche. Typically, investors adopt sustainable investing practices with financial performance in mind to optimize the risk-return profile, while not necessarily accepting lower returns in exchange for impact. Stocks with good ESG ratings may perform just as well as or even better than their peers in the market, often with less volatility, but recent years have also shown underperformance. In general, this is also a question of time-horizon, where sustainability investors adopt a more long-term perspective. A global study of institutional investors shows a certain mismatch between investors and companies; while 78% of investors stated that they would make business-relevant ESG investments even if this reduced their profits in the short term, only 55% of companies were willing to do so. This is probably due to the perceived pressure from short-term-oriented investors and sell-side analysts in the context of quarterly reporting. This perspective is particularly prevalent in North America, especially in the US. At the same time, many investors are concerned about companies cherry-picking and only disclosing ESG information very selectively. In the opinion of 80% of the investors surveyed, many companies are unable to convincingly explain the reasons for a long-term investment in sustainability, with the available ESG disclosures only being of limited assistance in decision-making.3
The “Big Three” asset managers and proxy advisors see financial importance of ESG
In their proxy voting guidelines, BlackRock, Vanguard, and State Street Global Advisors have in recent years defined clear requirements related to climate action, the transition to a net-zero economy, board and workforce diversity, and human capital management.4 Proxy advisors such as ISS and Glass Lewis have also introduced similar standards. While 2025 proxy voting guidelines still focus on sustainability-related financial risks and opportunities, BlackRock CEO Larry Fink omitted explicit mentioning of ESG and related terms in his latest 2025 Annual Chairman’s Letter to Investors5 — indicating a shift in framing ESG amid growing political pressure, especially in the US.
Investors continue to pay attention to the issue of climate change, one of the most urgent challenges of our time, and they analyze their portfolios’ exposure to physical and transition risks. This also includes seizing opportunities, applying robust climate scenario analyses, and aligning with net-zero targets through ambitious decarbonization strategies. Health and safety, security, diversity and inclusion, human rights, and labor issues are just as much a part of a balanced ESG debate as energy and emissions, water, and biodiversity.
