Who made the claim?
To get to the source of this we have to introduce two organizations: Skattebetalarnas Förening and a related project Slöseriombundsmannen. Both links are in Swedish. I could not find authoritative information in English but Skattebetalarnas Förening has a page on Wikipedia, with the English name Swedish Taxpayers' Association where we can read that it is…
…an association and taxpayers union in Sweden which advocates low taxes and efficiency in the public sector. The association was first founded in 1921…
In 2010 they started up a new project, Slöseriombudsmannen, where Slöseri can be loosely translated to waste. Wikipedia has this to say in English:
The association has a member working as Waste Mediator (“slöseriombudsmannen”) who has the responsibility to review the public funds used by the politicians and officials.
What is the claim?
Every year Slöseriombudsmannen holds a contest where the members can vote for what they believe has been the most wasteful use of taxpayer's money. I think the result is published here but I could not find a detailed summary about all the choices and specific questions. Here is some of the relevant information in that link:
- Over 18,000 people voted.
- The "winner" got 30% of the votes.
It also contains the motivation and background. It's not so much that it's bad to spend money on the environment, it's more that the money is spent on the wrong things and that it can be shown that what has been spent so far has not helped, but maybe even made it worse. They list a few specific projects like tax deductions for electric vehicles.
Do Swedes believe climate change spending to be the biggest waste of taxpayer money in 2019?
30% of 18,000 tax-critical Swedes believe that the specific spending were the biggest waste of taxpayer money. I will leave this up to a statistician to decide if this can be applied to the whole population.
