Did you know, for example, that six ships create as much pollution as all the world’s traffic? That three bitcoins generate as much energy as a million credit card transactions? Or that the last time CO₂ levels were as high as they are today, wooly mammoths were roaming the Earth?

In January 2017, Robeco decided to collect these amazing facts in a new series called SI’s Stunning Statistics. Every month we found an interesting new number from the world of sustainable investing, and added our own investment angle to it. Using the same format for each one, we asked three questions: What has happened? Why is it important? What does it mean for investors?

The best articles from this series are now available in a stunning little booklet.
