Burning Man 2011, Black Rock Desert, Nevada, United States

The Bureau of Land Management, which maintains the desert, has very strict requirements for the event. These stipulations include trash cleanup, removal of burn scars, dust abatement, and capture of fluid drippings from participant vehicles. For four weeks after the event has ended, the Black Rock City Department of Public Works (BRC – DPW) Playa Restoration Crew remains in the desert, cleaning up after the temporary city in an effort to make sure that no evidence of the event remains.
Burning Man and its effect on global warming
Burning Man's Carbon Dioxide footprint is primarily from transportation to the remote area. The CoolingMan organization has estimated that the 2006 Burning Man was responsible for the generation of 27,000 tons of carbon dioxide, with 87% being from transportation to and from the remote location. The Sierra Club has criticized Burning Man for the "hundreds of thousands" of plastic water bottles that end up in landfills, as well as ostentatious displays of flames and explosions.
In 2007 Burning Man's "Green Man" theme received criticism for Crude Awakening, the 99-foot oil derrick that consumed 900 gallons of jet fuel and 2,000 gallons of liquid propane to blast a mushroom cloud 300 feet high into the sky.
