Companies would be better investing in encouraging people to behave better on compus if they were serious, and I mean by actually investing to make using eco friendly things pleasent, not using brown paper to give printouts to clients or having some guy who shouts about the wrong paper going in the wrong bin all the time.
Companies should buy things that people want that produce less waste (yes this then drives cost up and profits down), consolidating physical services (it, printing, office space etc.) and using recycled products by preference (again good recycled paper is not brown toilet paper and can even be given to clients). And when companies start doing this rather than individuals it has a knock on effect on the market and affordability.
And finally, I'm sorry, I fail to understand why anyone needs to pay to be told this.
