I can share the process any business goes through. In every community, the NGO would create a milestone process of some kind. It starts with establishing some kind of a green team, or a group of employees who are responsible for the environmental performance or impact of the company. Then you go about getting an inventory of some kind of what the current baseline impact is. Then engage a consultant and use the tools and supports to create an action plan. Then understand from a management point of view which items of a payback period are acceptable in that action plan. Then set a target.
To the question about specific programs or projects for each company, that would be in that action plan. Of course it would differ so much between a VeriForm versus an Ernst and Young, or a hospital versus a utility. Typically it's some mix of looking at their fleet and seeing what efficiencies can be found, and looking at energy and starting with conservation. Those of course are the cheapest. They can then move to energy efficiency, then into renewables next and identifying for that particular firm which are the obvious ones, or the low-hanging fruit they ought to look at first, and then prioritizing later ones once they have some money flowing in from those initial projects.
