Supporting evidence

Rising Tide UK, "The case against carbon trading", 2002 - "You can't trade in something unless you own it. When governments and companies "trade" in carbon, they establish de facto property rights over the atmosphere; a commonly held global commons. At no point have these atmospheric property rights been discussed or negotiated - their ownership is established by stealth with every carbon trade."
