Claim: Environment Minister Greg Hunt the Coalition's emissions reduction fund, at $13.95 per tonne of carbon, is around 1 per cent of the cost of reducing carbon under the former Labor government's carbon pricing scheme, which he cost $1,300 a tonne.

Passage: The system aims at achieving the environmental outcome of reducing greenhouse gas emissions, the idea being that capping emissions creates a price for carbon and the ability to trade ensures that emissions are reduced at the lowest possible price (Department of Climate Change, 2008, 12).

Passage: There will be a price cap on emissions, that will start at AUD 40 per tonne of carbon dioxide equivalent.

Passage: The Australian government's Emissions Reduction Fund provides for purchasing carbon offsets from Australian carbon emissions reduction projects.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The tax that was to be implemented would be 2,400 yen ($20.85 in 2005 dollars) per tonne of carbon dioxide emitted from fuels.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The proposal would have set an emissions price of NZ$15 per tonne of CO2-equivalent.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: On 1 July 2012, the Australian Federal government introduced a carbon price of AUD$23 per tonne of emitted CO2-e on selected fossil fuels consumed by major industrial emitters and government bodies such as councils.

Passage: A carbon price — the method widely agreed to be the most efficient way for nations to reduce global warming emissions — is a cost applied to carbon pollution to encourage polluters to reduce the amount of greenhouse gases they emit into the atmosphere: it usually takes the form either of a carbon tax or a requirement to purchase permits to emit, generally known as carbon emissions trading, but also called "allowances".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: 1.0% lower and nine months after the introduction of the pricing scheme, Australia's carbon dioxide emissions from electricity generation had fallen to a 10-year low, with coal generation down 11% from 2008 to 2009.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Suppose a $30 carbon price is imposed on the (roughly) 5 billion tonnes of the U.S. emits each year, and suppose that causes emissions to drop 20% (in the long run) to 4 billion tonnes.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Australian Government said in July 2013 that the carbon tax was a factor in reducing the emissions intensity in the National Electricity Market from 0.92 t of CO2 per MWh to 0.87 in the 11 months following its introduction.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A carbon pricing scheme in Australia, commonly dubbed by its critics as a "carbon tax", was introduced by the Gillard Labor Government in 2011 as the "Clean Energy Act 2011" which came into effect on 1 July 2012.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The carbon price was set at AUD$23 per tonne of emitted CO-e on selected fossil fuels consumed by major industrial emitters and government bodies such as councils.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Carbon Pollution Reduction Scheme (or CPRS) was a cap-and-trade emissions trading scheme for anthropogenic greenhouse gases proposed by the Rudd government, as part of its climate change policy, which had been due to commence in Australia in 2010.
