Air quality inside buildings can be many times worse than outdoor air. Poor ventilation is partly to blame. But what you choose to furnish and clean your offices with has a huge impact. You might be shocked to learn about toxic chemicals in fabrics, formadehyde in cabinets, etc. Don't even get me started on the standard white board pens. Many of these chemicals accumulate in our bodies.
I dare you to google 'body burden.'
This research shows that these indoor pollutants aren't only bad for your employees (or students). It reduces their productivity. If you take this into account, you might be able to justify paying a little more for the greener interior products.
