The Association for the Study of Peak Oil and Gas, or ASPO, is a network of scientists, affiliated with a wide array of global institutions and universities, whose goal is to attempt to determine the date and impact of the peak and decline of the world’s production of oil and gas, due to resource constraints.

ASPO was founded by Colin Campbell

Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is...

. Campbell's critics, like Michael C. Lynch, argue that his research data is sloppy. They point to the date of the coming peak, which was initially projected to occur by the year 1997, but the date was pushed back to 2000, then 2010, moved up to 2006 (in 2004) and later (2005) back to 2010. Campbell explains this with the fact that he has got better data from industry and more reliable estimates. However, Campbell and his supporters insist that when the peak occurs is not as important as the realization that the peak is coming.

Mission

1. To evaluate the world’s endowment and definition of oil and gas;

2. To study depletion, taking due account of economics, demand, technology and politics;

3. To raise awareness of the serious consequences for humankind.
