Strato are Europe’s second largest hosting company and Strato are also carbon neutral! Amazingly they achieved this without buying any offsets. How did they do it?

If I heard you correctly you are now the largest hosting company in Europe? – 02:28

You guys are a bit like RackSpace in the sense that you don’t do co-location, you rent space on your servers, id that right? – 02:38

You mentioned that you decided to re-architect the setup in Strato and reduce your carbon footprint, was this for environmental reasons or business reasons? – 03:34
