Lets be cautious
Strikes me that it makes sense to be slightly more frugal and careful with Earth's natural resources. The post 9/11 grounding of Jets resulted in significant changes in the Atmosphere. The oil will run out eventually regardless of who we invade.
However I'm dubious our lords and masters can be trusted, all that seems to have happened is that they have put tax up for individuals. That suggests to me the current solutions to GW are a con.
Tax on running old cars - Surely rather than encouraging people to scrap old cars and having to dispose of them, then make new ones which will wipe out any carbon or fuel savings, we should be developing better exhausts for retrofitting? Instead of taxing users to run them why not add significant tax to the price of inefficient new ones?
Rather than having a disposable society why not insist manufacturers provide a 5 - 10 year warranty on significant items - TV / Video / washing machines etc which would push the price & quality up encouraging longer use and fewer old goods to dispose of.
Tax on rubbish - Instead of taxing householders on rubbish, why not use more sensible disposal methods (converting into fuel etc) and tax companies who provide excessive non bio degradeable wrappers?
Rather than taxing per person flying why not tax per flight based on the efficiency of the airplane, that would encourage Airlines to fly fewer planes and make sure they are efficient & full?
Why put up fares on public transport? If it is that much more efficient we need more people to use it so make it cheap.
Why if we need to cut travelling don't we make homeworking easier and more tax efficient?
Why if we need to cut pollution why not charge carbon miles on foreign food & goods? Long term with population growth in distant countries we will need to become self sufficient.
May be a wise idea to rein in population growth, fewer consumers will mean a slower growth in pollution.
Why not stipulate maximum emissions of overseas suppliers and encourage suppliers such as China to stop building coal fuelled power stations. While we are at it we can stipulate minimum standards of employment stopping child labour and exploitation.
The efficiency of manufacturing & fitting Wind Turbines etc to individual houses is doubtful, we need big solutions with efficiencies of scale.
Basically the government haven't got the guts to do the right thing & upset the party donors, so its unlikely we will have a significant effect.
