Get your neighbors to go green - reach out!

Create a "Green Team".
Create an in-house "Green Team" explicitly responsible for managing all environmental initiatives, and that meets at least quarterly.
Host
an in-office educational session.
These sessions will inform staff
of the company's participation in the Green Office Challenge, and can help them
"go green" in the office and at home.

Celebrate
Earth Day in the office, or designate a “Green Week.”
By celebrating Earth Day or having
a "Green Week" full of sustainably related activities are great ways
to engage employees.
Create
a Sustainability Policy.
Having a sustainability policy
informs management, employees, stakeholders, suppliers, public, etc of the
sustainability practices the company adheres too. Including a green purchasing
portion to the policy is key.
Encourage
fellow businesses in the central business district, or fellow tenants in
your building to join.
Refer others to join the Challenge.
Implement innovative green practices.
Perform innovative green practices
(conducting a waste audit, composting food, energy reduction competitions
within your office, recycle plastic bags, calculate the company’s carbon
footprint, the possibilities are endless).
