What Green Economy? First you have to define it, then create it. Most posts on here are extremely generalistic, with no real substance.
To foster a GREEN ECONOMY, you should be publicizing truly green innovation in business and commerce. But first, clearly define what you mean by "green"?
There are tremendous number of ways one could think about going "green". Using less energy, driving less, buying local, substituting dangerous chemicals for safer ones in products, developing more sustainable manufacturing processes and feedstocks, increasing recycling, using renewable energy, and on and on.
I suggest you first become focused on a single issue, whatever that may be, and work on that issue, and then expand to other issues as you gain insight and knowledge. Partner with the UC and other scientific think tanks to develop web content relevant to the public as a whole. Start small and expand in the future, as you get experience.
Publicizing truly innovative and truly "green" new technologies and products would be a great place to start. Many municipalities have, and are hungry for more, environmentally preferable purchasing programs that focus on procuring "green" products. Consumers also seem to have interest in such information. Expand resources available to these entities (list green products for example) to foster green purchasing, which in turn can drive markets and create the green economy you desire.
