About ASPO

A brief background

Colin J. Campbell:
"It was in Germany that ASPO had its origin. On December 7th in the year 2000, I was privileged to give a talk on oil depletion at the ancient university of Clausthal in the Harz Mountains. The idea of forming an institution, or network of scientists concerned about the subject, developed. Next day, I took the idea to Professor Wellmer, the head of the BGR in Hannover, who gave it his support. The Norwegians were the next to join, followed by the Swedes. Today, ASPO is represented in almost all European countries.

The next step forward came when Professor Aleklett organised the first International Workshop on Oil Depletion in Uppsala in May of 2002, to be followed by workshops in Paris and Berlin.



ASPO is an informal network working with a very small budget, yet its voice is being heard, thanks in part to the Uppsala website. Perhaps its informal structure is its strength. It means that it can tell the truth freed of all the political, legalistic and commercial constraints that most organisations face. By all means, the subject of depletion is a sensitive one, being perhaps the most important single issue facing the modern world".

ASPO is a network of scientists, affiliated with institutions and universities, having an interest in determining the date and impact of the peak and decline of the world's production of oil and gas, due to resource constraints.


ASPO's mission is to:

  1. Define and evaluate the world's endowment of oil and gas;
  2. Model depletion, taking due account of demand, economics, technology and politics;
  3. Raise awareness of the serious consequences for Mankind.
