At a convention in Seattle Mayor Bloomberg advocated for a national carbon tax to incentivise the reduction of carbon emissions. He called a “cap & trade” method more politically feasible, but he went on to say that a carbon tax is the much better structure, as it puts a clear price on polluting.
He would balance out a pollution tax with a corresponding tax cut, so it would be revenue neutral. On an individual scale, it would encourage people and companies to watch where they release their carbon.
