Australia is killing their carbon tax proposals and it's already a complete failure in Spain, where it's resulted in an 18.1 percent unemployment rate (more than double Europe's average) and they are losing 2.2 jobs per every one "green job" created.
I think The New York Times quote on the European Union's cap-and-trade program (that started in 2005) says it all: "Their plan unleashed a lobbying free-for-all that led politicians to dole out favors to various industries, undermining the environmental goals. Four years later, it is becoming clear that system has so far produced little noticeable benefit to the climate, but generated a multi-billion dollar windfall for some of the continent's biggest polluters."
