Well, an easy idea would be to get folks to sign up for a group on Mission Zero as a company, then you could create Missions of your own (your challenges). It's a great way to highlight what your company is doing and keep people motivated about sustainability initiatives. I know - kind of an obvious one . . .

Here are a few things that might seem hard at first, but ended up being really fun and having real results. One office that we work with - who was trying to drive awareness of waste in their office - in a fun way - took away everyones personal trash bins and put in centralized bins in key places in the office -tiny step, but it made everyone aware of what they waste and actually decreased the amount of paper and other waste in their office (they measured at the beginning with all waste cans - and after a few weeks with the centralized one. Also, I know lots of offices who are measuring their employee's carbon footprint with easy online calculators and seeing who can decrease their footprint the most by awarding things like Ipods and digital cameras.

We have a can crusher in the office and it certainly is fun to use. Try this: http://www.google.com/products?q=can+crusher

Not really a competition, but I know a lot of offices post a car pool sign up lists where people who are interested in carpooling during the week can post their name and general area that they live in. People are always looking to save gas money, regardless of how eco-conscious they are...

I just read this on the Ethical Performance website and wanted to pass it along - the talk about how Kelloggs hired actors to come and educate their employees. The cereal manufacturer Kelloggs has taken the unusual step of using undercover actors to convey waste-cutting messages to employees.The two female thespians, from the CragRats theatre company, were sent into Kelloggs’ UK headquarters in Manchester as cleaners. As they worked through the four floors, emptying bins and tidying up, they confronted unsuspecting staff with lighthearted comments about their wasteful habits and inattention to recycling. Kelloggs’s community and social responsibility manager Bruce Learner, who commissioned the stunt, said it was meant to ‘stir up’the 550 employees, and had caused a degree of consternation. However, the exercise proved to be a successful way of reinforcing ‘reduce, reuse and recycle’ messages. WHAT A GREAT IDEA

Good call, Erin: Surprisingly enough, hiding the trash can at work, and using the main office trash bin has been motivating to throw away less, and keep my desk cleaner. -- Overall, when the more sustainable option is actually simpler or *easier* than a wasteful option, it tends to see a better adoption rate. : )
