Coalition’s Net Zero U-Turn: Debunking the Claims

The Liberal and National parties’ recent abandonment of support for Australia’s 2050 net zero emissions target has been accompanied by a series of bold claims about costs, electricity prices, and alternative solutions. However, many of these assertions don’t stand up to scrutiny from experts and academic research.

The $9 Trillion Misrepresentation

Nationals leader David Littleproud has repeatedly claimed that reaching net zero would cost Australian taxpayers $9 trillion, mentioning this figure 15 times in a single interview on Thursday. This claim allegedly comes from research by Net Zero Australia, a partnership between academics at the universities of Melbourne, Queensland, and Princeton University.

However, Net Zero Australia has issued a statement clarifying that their findings have been misrepresented. The actual additional cost of building an energy system to reach net zero emissions by 2050 would be approximately $300 billion – dramatically less than the Coalition’s figure.

The $9 trillion figure refers to potential capital investment through to 2060 for both domestic energy developments and export-oriented projects. Crucially, Net Zero Australia specified that the “large majority” of this investment would be underwritten by overseas customers rather than Australian taxpayers. Far from being a burden, this investment would create significant new industries and jobs across the country.

Multiple studies have consistently found that the cost of climate inaction would vastly exceed the cost of transitioning to clean energy.

Electricity Price Increases: Not a Renewable Energy Problem

Liberal leader Sussan Ley claimed that power bills have increased by about 40% since Labor’s election, suggesting this rise stems from renewable energy investments made to meet emissions reduction targets.

Energy industry experts firmly reject this connection. Tony Wood, senior fellow at the Grattan Institute and former Origin Energy executive, states the price increase had “almost nothing to do with renewable energy.”

The real culprits behind the approximately 20% spike in 2022-23 were Russia’s invasion of Ukraine driving up global gas prices, coal price jumps after flooding at east coast mines, and reduced generation capacity due to outages at aging coal plants. The post-pandemic economic rebound and inflation also contributed to higher prices.

When asked for evidence that renewable energy was driving up electricity costs, Shadow Minister for Energy Dan Tehan offered only the circular reasoning that “people are seeing it every single day in their electricity bills.”

In fact, research from Griffith University’s Centre for Applied Energy Economics suggests the opposite – electricity generation costs could be up to 50% higher had Australia relied solely on fossil fuels instead of pursuing renewable energy development.

According to Dylan McConnell from the University of New South Wales, while rebuilding the power grid will inevitably be costly, analyses consistently show that renewable energy plus firming support remains the most cost-effective pathway for Australia’s future electricity system.

Paris Agreement Compliance: Technically In, Practically Out

The Coalition maintains Australia could abandon emissions targets while remaining in the Paris Agreement. Technically this is true – Australia wouldn’t be forcibly removed. However, such a move would clearly violate the agreement’s core principles.

Article 4.3 of the Paris Agreement explicitly requires successive commitments to “represent a progression” and “reflect its highest possible ambition.” Backsliding is not permitted under the agreement, which aims to limit global warming to well below 2°C while pursuing efforts to limit it to 1.5°C.

The Intergovernmental Panel on Climate Change has determined that meeting the 1.5°C goal requires a 45% global emissions cut between 2010 and 2030, and reaching net zero “around 2050.” The Coalition’s new position directly contradicts these requirements while claiming to remain committed to the agreement.

Coalition’s Emissions Reduction Record: Nature Did the Heavy Lifting

While emissions did fall approximately 21% between 2013 and 2022 during the Coalition’s time in office, the majority of this reduction had little to do with federal policy.

Most of the decrease came from increased carbon dioxide absorption by forests and land. Experts attribute this to state government restrictions on land clearing and native forest logging, plus the end of a major drought – not federal initiatives.

Excluding these natural factors, climate pollution decreased by just 3% over those nine years, mostly due to renewable energy investments driven by a 2020 target that was established under Labor and that then-Prime Minister Tony Abbott attempted to dismantle in 2014.

Transportation emissions also dropped sharply during COVID-19 lockdowns as mobility decreased, but emissions from transport, heavy industry, manufacturing, and mining otherwise increased during the Coalition’s tenure.

Carbon Capture and Storage: Not a Quick Fix

Despite Shadow Energy Minister Dan Tehan’s claim that carbon capture and storage (CCS) could “provide immediate relief” for emissions reduction, the evidence suggests otherwise.

Despite decades of government funding totaling billions of dollars, CCS projects have delivered minimal results. According to the Global CCS Institute, 77 operational projects worldwide capture up to 64 million tonnes of CO₂ annually – representing just 0.17% of global emissions.

Moreover, nearly half of these projects are used for “enhanced oil recovery,” where captured carbon is used to extract more fossil fuels, undermining their climate benefit.

As Australia reconsiders its climate commitments, the gap between political claims and factual evidence continues to widen, with experts consistently pointing to renewable energy as the most cost-effective and practical path to emissions reduction.
