ASPO (The Association for the Study of Peak Oil and Gas) is a network of non-profit, independent organisations based in many countries with the following shared aims:

• To evaluate the world’s endowment of oil and natural gas;
• To determine the probable date and impact of the peak and decline of the world’s production of oil and gas;
• To pursue the release of reliable and transparent data on the world’s oil and gas reserves/production rates in order to provide a firm basis for policy-making;
• To raise international public awareness and promote better understanding of oil and gas depletion and its consequences;
• To urge governments to adopt strategies to mitigate the effects of oil and gas depletion with new policies aimed to cut waste, improve energy efficiency, and bring in alternative energies;
• To promote the adoption of an Oil Depletion Protocol, whereby consumption is reduced to match a declining supply;
• To warn of the consequences of delay.
