Agents with the EPA and Secret Service began investigating Gunselman and his company Absolute Fuels, LLC in late 2011 after an employee made claims he was selling fraudulent carbon credits.
A KAMC investigation uncovered Gunselman's scheme to sell phone carbon credits to companies required by law to buy them, netting him nearly $50 million dollars.
Gunselman has since pleaded guilty to dozens of counts of fraud.
Court documents show Gunselman spent millions on a lavish lifestyle.
The forfeiture order signed Friday includes $12 million in cash, nine pieces of property--including at least 300 acres of farmland, nine cars--including a Bently and a Shelby Cobra--and unusual items like a private jet, demilitarized tank and a flamethrower.
Former friends and employees of Gunselman have said he also spent lavishly on trips, often taken employees on last-minute trips to Las Vegas, and renting a suite at San Antonio Spurs games.
Gunselman is scheduled to be sentenced next week.
