    Marketing hype, butane has replaced Freon as a propellent in many
    aerosol spray cans, this is where the "ozone friendly" BS comes from

    Nope propane (C8H8) is a petroleum processing product as is butane,
    this is from the NPGA site 

          "Approximately 90 percent of the United States' propane supply
          is produced domestically, while 70 percent of the remaining
          supply is imported from Canada and Mexico. Approximately equal
          amounts of propane come from the refining of crude oil and from
          natural gas processing." 

    Natural gas is mostly methane CH4. 

    Methyl acetylene and propadiene (MAPP) is also a manufactured fuel
    gas. 

    If you are burning hydrocarbons you are affecting the environment.
    There is no environmentally safe or neutral torch fuel with the
    possible exception of hydrogen (hydrogen production is not a "green"
    process).
