The Claim
“Refused to release modelling to support the claim that their climate policy can achieve the targets they say it will.”
Original Sources Provided
✅ FACTUAL VERIFICATION
The claim that the Coalition initially refused to release climate modelling is factually accurate. When Prime Minister Scott Morrison announced the 2050 net-zero target on 26 October 2021, he stated modelling would be released "eventually" but refused to provide it at the time of announcement [1]. The government resisted a Senate order on 21 October 2021 requiring Energy Minister Angus Taylor to table the modelling, with the deadline passing without release [2]. However, this refusal was not permanent—the Coalition subsequently released detailed economic modelling on 12 November 2021, approximately two weeks later [3].
The initial modelling that was kept secret included breakdowns of emissions reductions by sector, economic impact projections, and assumptions about technology breakthroughs [1]. The government stated modelling would be released after concluding negotiations with the Nationals and finalising policy details [2].
Missing Context
Timeline and Resolution:
The claim is misleading without acknowledging that modelling was eventually released. This was not a permanent refusal but a delay during the negotiation phase with the Nationals. The two-week delay occurred as the government finalized concessions to the Nationals in exchange for their support of the net-zero target [2]. The Treasury subsequently released "Australia's Net Zero Transformation: Treasury Modelling and Analysis" which examined economic impacts and pathways [3].
Reasons for Initial Delay:
The government's stated reason for the delay was that negotiations with the Nationals were ongoing, and releasing detailed modelling before finalizing those negotiations could have undermined the negotiating position. Deputy PM Barnaby Joyce had issued warnings that "it will be ugly" if Morrison committed to net-zero without Nationals backing [2]. The government indicated modelling would be released before the Prime Minister attended COP26 talks [2].
Legislative Context:
The Coalition had resisted calls to enshrine the 2050 target in legislation, arguing their "technology not taxes" approach did not require new laws [1]. This philosophical difference with Labor meant the timing of policy details was treated as an election campaign matter rather than an urgent legislative requirement.
Source Credibility Assessment
The original source provided is The Guardian Australia, which is a mainstream news organization with a center-left editorial position [4]. The Guardian's reporting on this issue included documented facts (the Senate order, the missed deadline) but used language reflecting skepticism about the Coalition's approach ("committed to secrecy," "refusal to disclose"). The reporting was factually accurate but included interpretive framing that emphasized the Coalition's lack of transparency rather than the temporary nature of the delay.
Secondary sources cited (Renew Economy, AFR, SMH) represent the full political spectrum. Renew Economy is pro-renewable energy advocacy journalism. The AFR and SMH are mainstream outlets that reported both the initial refusal and subsequent release [3].
Labor Comparison
Did Labor do something similar?
Search conducted: "Labor climate policy modelling transparency 2030 target"
Labor also faced criticism for insufficient modelling and transparency on climate policy. After the 2019 election where Labor's 45% 2030 emissions reduction target was defeated, the party abandoned the target and did not announce a new climate policy until after COP26 [5]. By contrast, Morrison announced his target before COP26, even if initially without modelling [1].
When Labor eventually announced its 43% emissions reduction target in 2022, the party removed detailed modelling from its website according to energy experts, with criticism that Labor would "fail to meet key targets" from its own energy policy [6]. This suggests Labor also engaged in selective presentation of climate policy information.
Labor's 2022 climate policy also faced criticism from the IMF, which suggested the 43% target could equate to a $255 carbon price or $4,500 per household costs by 2030—costs Labor had not fully transparently modelled at the time of announcement [7].
Key difference: The Coalition delayed modelling release by two weeks during negotiations; Labor appeared to remove modelling from public view entirely and did not release a climate plan until after a major international summit.
Balanced Perspective
The Case for "Refused to Release":
Critics were justified in calling out the initial refusal, as governments making major policy commitments should provide transparency immediately. The Senate order to release modelling (which passed cross-party) reflected legitimate democratic accountability concerns [2]. Labor, Greens, and environmental groups correctly identified that 2050 targets of limited immediate value without detailed implementation pathways and mid-century trajectory projections [1].
Morrison's own statement that 15% of the abatement task relied on "technology breakthroughs" that hadn't yet been invented was legitimately concerning to critics [1]. Technology optimism assumptions can inflate claimed policy outcomes.
The Coalition's Justification:
The government argued that releasing partial modelling during Nationals negotiations would have undermined their negotiating position. Political negotiations with coalition partners often require staged disclosure of policy details [2]. The two-week delay was operationally necessary to finalize policy specifics.
The released modelling projected that net-zero would leave Australians nearly $2,000 better off by 2050, with gross national income 1.6% higher than a no-action scenario [1][3]. These positive economic projections could have been released earlier, but the government sequenced the announcement with the Nationals deal.
Comparative Analysis:
This appears to be a normal political practice across parties. Labor also timed major policy announcements (delaying their climate plan until after COP26) and later faced criticism for not providing adequate modelling for its own target [5][6]. The key difference is that the Coalition's delay was measurable and temporary (14 days), while Labor's approach was more sustained.
Morrison's "technology not taxes" philosophy also explained why detailed day-one modelling wasn't available—the government's model assumed technological cost reductions that would be realized through market competition rather than mandated policies, making mid-century assumptions inherently uncertain.
Key context: The refusal to release modelling immediately was not unique to the Coalition. However, Morrison was correct that "no one could predict advances over the next 30 years," which is why technology-heavy 2050 targets inherently have substantial uncertain components [1].
PARTIALLY TRUE
6.0
out of 10
The claim is factually accurate that the Coalition initially refused to release modelling when the net-zero target was announced on 26 October 2021. However, the claim is incomplete and misleading because:
- The refusal was temporary (14 days), not permanent [1][2][3]
- Detailed Treasury modelling was released on 12 November 2021 [3]
- The delay occurred during coalition partner negotiations, which is standard political practice [2]
- Labor similarly delayed climate policy announcements and has faced criticism for removing modelling from public view [5][6]
The more accurate statement would be: "The Coalition delayed releasing detailed modelling for two weeks after announcing the 2050 net-zero target, citing ongoing negotiations with the Nationals, but ultimately released comprehensive Treasury analysis before attending COP26 talks."
