[1] The ISPO describes itself as "a growing association of citizens world-wide who aim to use their votes in a new, co-ordinated and effective way to drive all nations to co-operate in solving our planetary crisis".

With more and more parliamentary seats and even entire elections increasingly being won or lost on very small margins, a relatively small number of Simpol adopters have the opportunity, ISPO claims, to make it in the strong interests of all politicians and parties to pledge to implement Simpol's policy package while also making it potentially disastrous for them if they fail to do so.

Simultaneous initiatives are seen as a way to avoid Prisoner's dilemma type problems, wherein there is a strong reward for defecting, and a risk for going along with a proposed plan if there is even one defector.

[5] The Simultaneous Policy presently has campaigns running in twenty seven countries:[6] Australia, Austria, Bangladesh, Belgium, Brazil, Cameroon, Canada, Denmark, East Africa region, Germany, Hungary, Iceland, India, Ireland, Italy, Luxembourg, Mali, Malta, Nepal, New Zealand, Nigeria, Pakistan, Spain, Sweden, Switzerland, United Kingdom and Uruguay As the United Kingdom was first to campaign it has more politicians who have signed the pledge.

These politicians come from across the political spectrum: Individuals who have signed but are no longer MPs are: Conservative Party: Sir Richard Body; Labour: Celia Barlow, Tony Benn; Liberal Democrat: Lembit Öpik, John Hemming[7] In addition, there exists a growing number of Simpol partner organisations that support the democratic aims and principles of the Simultaneous Policy.
