A study by The Conversation shows how the carbon tax has cost Australia millions.
The study has found that the cost to the country is $7,700 for every dollar spent on the tax.
The Coalition has not responded to questions about the study.
The report was commissioned by the ABC.
The Government has said it is not aware of any evidence to support the cost estimates, but it has been criticised by some climate campaigners and the Greens.
The research shows that over the last two years Australia has invested $1.3 trillion to tackle climate change.
The country has spent about $2.5 billion on the carbon emissions trading scheme, with more than half of that coming from fossil fuels.
The majority of this has come from renewable energy sources.
Australia’s share of the emissions trade scheme was $2 billion last year, according to the report.
The analysis also looked at the economic impact of the tax on the economy and on jobs.
The carbon tax would cost about $7.7 billion over the next five years if it was implemented in full, or about $9.2 billion if it were only implemented in part, according the study from the Centre for Economics and Business Research.
The Australian Bureau of Statistics estimates the cost of carbon emissions to the economy in the next decade to be about $3.4 trillion.
