WASHINGTON — The Institute for Energy Research released today a study entitled Australia’s Carbon Tax: An Economic Evaluation. The study, conducted by Dr. Alex Robson, an economics professor at Griffith University in Brisbane, Australia, assesses the economic impacts of Australia’s carbon tax and draws lessons for U.S. policymakers who may be considering similar taxing schemes. The study is published as Australia prepares to hold a general election on Sept. 7 that many observers view as a referendum on the nation’s now 12-month old carbon tax.

As the study demonstrates, the real world results in Australia greatly undermine the claims made by U.S. proponents of a carbon tax, particularly for those who purport to represent a pro-growth, conservative agenda. In the end, every single claim made in the case for a carbon tax has the exact opposite effect in Australia, a lesson that should be instructive for U.S. policy formation.

“Poor policy processes tend to lead to poor policy outcomes. Australia’s carbon tax experience provides a number of important lessons in how not to go about implementing sensible climate change policy,” Robson states in the paper.

“Although a number of Government reports examined the possible costs of the carbon tax, none of them assessed the incremental net benefits of the policy. For a variety of reasons, it is unlikely that Australia’s carbon tax will achieve ‘abatement at least cost.’ The most significant complementary climate change policies have remained in place after the introduction of the tax, and a range of new, costly measures were introduced to accompany the policy. These factors have weakened—perhaps fatally—the economic case for Australia’s carbon tax.”

Some U.S. policymakers continue to offer a carbon tax as the way to simultaneously achieve environmental goals for global carbon emissions while reducing other tax burdens faced by small businesses and low- to middle-income families. IER commissioned the study of Australia’s experiment with carbon taxes to examine the real world effects that such policies have on energy markets, prices, and household budgets.

Among the study’s key findings:

  • In the year after Australia’s carbon tax was introduced, household electricity prices rose 15%, including the biggest quarterly increase on record.
  • Currently 19% of the typical household’s electricity bill is due to Australia’s carbon tax and other “green” programs such as a renewable energy mandate.
  • The job market had previously been stable, but after Australia’s carbon tax, the number of unemployed workers has risen by more than 10%.
  • Because Australia’s exports are relatively emissions intensive, the practical result of the Australian carbon tax serves as a tax on exports and import-competing industries.
  • Australia’s carbon tax was accompanied by income tax increases for 2.2 million taxpayers.
  • Due to fiscal gaps that exist between carbon tax revenues and increased government spending that accompanied the scheme, Australia’s budget bottom line will worsen as higher deficits and greater public debt increase.
  • Carbon dioxide emissions have actually increased, and will not fall below current levels until 2043, according to the Australian government.
