The Disclosure Project is an organization started by Greer in 1993 that alleges the existence of a US government cover-up of information relating to unidentified flying objects (UFOs). The Project has adopted Greer's contention that UFOs are spacecraft piloted by intelligent extraterrestrial life, and that the United States government is keeping this secret. Greer also uses the project to disseminate his beliefs that the government has concealed advanced energy technologies obtained from the extraterrestrials by suppressing and hiding them in top secret "black projects" in order not to upset the global geo-political power and energy-sector financial status-quo and its oil industry "special interests".
Greer and the Disclosure Project call for congressional hearings of all data regarding UFOs, including the large amount of information they claim is being hidden, and for release of the technology they claim is being suppressed, particularly free energy sources. He uses written statements and accounts from military personnel and defense industry employees as evidence for the various claims associated with the Disclosure Project.
The Disclosure Project has been well-received by UFO enthusiasts, with speeches from Greer and various other witnesses being presented at various UFO-themed conferences. Greer has held press conferences and embarked on a continuing series of lectures and television appearances trying to raise popular support. Mainstream media coverage of the group mostly centered around a 2001 conference at the National Press Club which was described by an attending BBC reporter as the strangest he had ever seen. Greer convened the conference with more than 100 other contactees offering testimony and arguing for investigations into a UFO conspiracy theory. Such arguments were met with by derision by skeptics and spokespeople for the U. S. Airforce who claim that there is no convincing evidence for the speculation that UFOs are alien spacecraft
