“Sustainable investing” explained

Updated in September 2025

Can investments actually generate a positive impact for society and the world, and if yes, how? In what way do different types of investments differ, what are the risks? How can you invest – and how can you get out if you need the money?

Sustainability and Investing actually have a lot in common. At first glance, both seem easy: Do recycle but don’t drive a car. Put some money in shares when they are low and sell them when they are high. But once you look a little deeper, behold! Complexity! A car with five passengers can be more ecological than a near-empty train. How do you determine when a share is “low” and when it is “high”?

The first green investment hype of the early 2020s has ebbed. “ESG investing”, meaning investments which consider Ecological, Social and Governance factors, has come unter increased scrutiny. Was it all just a fad? Or has the industry learned how to achieve sustainable growth and to transition to a green financial system?

This section will address these questions and more. You’ll find the available types of investments categorised in two ways:
Traditional investments, such as shares, funds or bonds are well established and often available through your bank.
Alternative investments focus on newish, niche opportunities. The nature of these investments often permits a more direct social and environmental impact.
