This is all about politics and not about fairness or the environment.
Taxing CO2 is crazy. The world needs CO2 to survive and present levels of CO2 in the environment compared with historic levels are difficult to quantify. Some say there are extremely high and others say that are very low causing a degree of starvation for the vegetation that requires CO2 and converts it to O2 for us to breath.
There is no way we can consider Carbon Dioxide a pollutant. It is colourless, odorless and essential for life. Nature around us is very efficient at dealing with CO2, including the oceans removing excess amounts and converting it to massive amounts of limestone and other carbonate rocks, and plants doing their magic of photosynthesis.
Its also been found that plant life flourishes in the areas around CO2 sources like coal-fueled power stations which use scrubbers to remove particulate matter and other nasties from the chimneys to allow sunlight and carbon dioxide to work the miracle of photosynthesis. Similarly for CO2 sources like volcanoes.
“The fundamental reason why carbon dioxide in the atmosphere is critically important to biology is that there is so little of it. A field of corn growing in full sunlight in the middle of the day uses up all of the carbon dioxide within a metre of the ground in about five minutes.”

There may well be environmental problems are associated with other carbon derivatives, such as CO (carbon monoxide) and the many fluorocarbons etc. But I do not believe spending money to reduce CO2 is the right approach to the stewardship responsibilities we have to look after the Earth on which we live.

So my perspective: Yes we need to be good stewards of the environment we have. But CO2 is not a pollutant nor a problem and placing a tax cost on CO2 is just a grab for tax revenue and votes at the next election. The tax, nor any subsequent reduction in CO2 emissions will have any positive impact on protecting our environment.
