GreenWorks was a program the Pennsylvania Department of Environmental Protection put together. In the late 90's they decided they needed a strong logo to represent their website to promote green education. This program was way ahead of the current trend to become more green.
In an effort to create a clean, environmentally friendly design we used blue to represnt the clean sky and green representing the grass and/or environment. We create the swoosh to show movement and recycling.
While this part of the organization was active this logo helped brand GreenWorks. Sadly, this project is no longer active as it was in the '90's and early '00's.
