World upside down, global south and north

In the last few decades environmental sustainability has been become a universal value- atleast in language even when not in action- and how this has taken shape in various parts of the globe. When development and economic growth and prosperity are the utmost goals globally it is not surprising that the global south's position on sustainable measures is also concerned with the limitations this would impose on their ability to develop based on exports of their resources- particularly when that is exactly part of how the global north has gotten to where it is. And yet the North is arguing that everyone must follow the same guidelines and principles and condemns the methods in which many of the nations in the global south live their basic life (ie use of forests to for fuel for cooking etc.). So where do we go in a world where no body will take responsability for anything and everyone just points fingers and where the trend is to talk solution but never action. Does it have to change and if so who and how....?
