A designer's role

A visual communication designer can have different roles:

1) A VC designer can manipulate words, create images and specify materials.
Green design it is a matter of finding and using better materials like nontoxic ink, tree-free paper, ...

2) A designer can help clients to strategize about how to build a strong brand and craft communications that resonate with their target audiences.
Gree design can craft and deliver messages that have a positive impact on the world or build strong brands for values-based companies who educate their costumers about social and environmental issues.

3) A VC designer can effect change and help clients to change the way people think and/or the way they act. (change actions of audience, clients and peers)
Green design is force for positive change (people who are touched by our work)

For my master's thesis I want to focus on the role of the designer as agent of change. But the other two roles will always be part of an convincing arguement for sustainability and green design. (Green Graphic Design)
