This is the first carbon-neutral documentary. NativeEnergy, which works with individuals and organizations to help them compensate for their contributions to global warming, calculated the "carbon footprint" from producing the film, including all travel, office, and accommodations related emissions. The company then offset emissions through renewable energy credits or "green tags from new renewable energy projects. Paramount Classics and Participant will split the cost of these tags; the funds will go towards helping build new Native American, Alaskan Native Village, and farmer-owned renewable energy projects, creating sustainable economies for communities in need and diversifying our energy supply. As Participant founder
Jeff Skoll explains: "It would be ironic, not to mention wrong, if we added to the global warming that
Al Gore warns about in his film. Plus, these renewable energy projects offer options that will decrease our demand for fossil fuels and otherwise would likely not happen without these kinds of investments." Participant, NativeEnergy and Warner Bros. partnered in a similar way on
Stephen Gaghan's film,
Syriana (2005), where 100% of the carbon dioxide emissions generated by the production were translated into investments into renewable energy. This follows on from the first "carbon neutral" film
The Day After Tomorrow (2004), which director
Roland Emmerich paid for out of his own pocket.
