Alberta's Tar Sands

I really like the idea of using a scale, 1-5, to rank people's support concerning issues such as the Alberta Oil Sands.

In regards to questions about environmental policy decision making, the wording of who has the greater influence or who people think would be most effective of initiating policies regarding sustainable actions are quite different. What are we wanting to measure? 1)Who people think would be most effective in formulating and ensuring environmental policies are sustainable? OR 2)Which actors people think have the strongest influence in ensuring that environmental policies are sustainable?

or both?
