The Hirsch report, the commonly referred to name for the report Peaking of World Oil Production: Impacts, Mitigation, and Risk Management, was created by request for the US Department of Energy and published in February 2005. It examined the time frame for the occurrence of peak oil, the necessary mitigating actions, and the likely impacts based on the timeliness of those actions.

The Lead Author, Robert Hirsch, published a brief summary of this report in October 2005 for the Atlantic Council.

"The peaking of world oil production presents the U.S. and the world with an unprecedented risk management problem. As peaking is approached, liquid fuel prices and price volatility will increase dramatically, and, without timely mitigation, the economic, social, and political costs will be unprecedented. Viable mitigation options exist on both the supply and demand sides, but to have substantial impact, they must be initiated more than a decade in advance of peaking."

A number of industry petroleum geologists, scientists, and economists were listed with their global peak production projection. Later, in 2010, Hirsch developed a projection that global oil production would begin to decline by 2015.
