First of all, a green fund as proposed can be looked upon for his contributors as an investment vehicle with the benefit of having a ROI and changing the world into a better place. This is a very important differentiation to associations like Greenpeace or WWF where people give donations and get a tax discount.
 
I propose a fund that has the following aims:
•    forcing companies and industries to a more efficient use of natural resources
•    keeping the interests of the society on a global scale on its agenda
and
•    offering its investors a reasonable rate of return.
 
6 steps towards sustainability:
 
1.    Diligence - search a target company
2.    Buy major stake of the target  
3.    Appoint CSO (Chief Sustainability Officer)
4.    Reformulate strategy, mission, vision, values etc.
5.    Rebuild business processes / use of ressources
6.    Monitor company
 
Influencing the Sustainability of Companies Business Processes  using AGFs and CSOs
One long-term goal is the establishing of an image of the fund that gets companies and whole industries thinking about their practices by infusing fear or at least respect for the funds activities. Through liquidating some real nasty-working companies, it should be possible to tip off a multiplication effect: „Hey, there are some guys acting in the best interests of society and environment. And they are not pretty nice to companies exploiting people and nature. Maybe we should rethink our identity and strategy.“
