According to a recent survey by the Pew Research Center, the general public is not much interested in global warning or the environment. The importance of energy policy has also slipped as a matter of public concern. This would suggest that policy initiatives that involve using taxes as a strategy to move consumption away from fossil fuels will face an uphill struggle.
In part this report suggests that:
“Dealing with global warming ranks at the bottom of the public’s list of priorities; just 28% consider this a top priority, the lowest measure for any issue tested in the survey. Since 2007, when the item was first included on the priorities list, dealing with global warming has consistently ranked at or near the bottom. Even so, the percentage that now says addressing global warming should be a top priority has fallen 10 points from 2007, when 38% considered it a top priority. …
Protecting the environment fares somewhat better than dealing with global warming on the public’s list of priorities, though it still falls on the lower half of the list overall.”
