What’s behind the recent changes at Good magazine?

I just opened the new issue of Good magazine — the magazine with the best paper smell — and was surprised by the answer give to the first letter to the editor.

Our big focus is on doing more with less — which is why we’ve shifted from six issues a year to being a quarterly, as well as using a more strategic distribution system (fewer newsstands mean less waste) and seriously increasing the amount of content online.

Now, I appreciate Good magazine’s effort to reduce their impact on the environment, but I can’t help but thinking that the reason behind these changes is in fact economical. C’mon, “fewer newsstands mean less waste?” And how much money are you going to save by doing this?
