The High-Stakes Gamble of Carbon Markets: Will the ETS Survive?
Carbon pricing is often presented as the “silver bullet” for achieving net-zero goals. By putting a price on pollution, governments aim to make it more expensive to emit greenhouse gases than to invest in green technology. However, the mechanism behind this—the Emissions Trading Scheme (ETS)—is currently facing a critical crossroads.
Recent warnings from the Climate Change Commission suggest that without significant reform, the scheme is on track to fail. The core of the issue isn’t just about the environment; it’s about economic stability and the ability of businesses to plan for a low-carbon future.
The Volatility Trap: Why Stability Matters
For a carbon market to drive real change, it needs predictability. Businesses don’t invest in multi-million dollar decarbonization projects based on a whim; they require to know what the cost of carbon will be five or ten years down the line.
The Climate Change Commission has warned that the current trajectory leads toward “huge future volatility.” If the market becomes too unstable, the incentive to innovate vanishes, replaced by a desperate scramble to manage short-term costs.
To combat this, the commission has advised the government to maintain current auction unit pricing, and volumes. The goal is simple: prevent price instability before it triggers a market panic.
The Risk of “Economic Harm”
One of the most pressing concerns is the potential for a unit shortfall. Jo Hendy, chief executive of the Climate Change Commission, has highlighted that a shortfall as early as 2028 could lead to severe price spikes.
When the price of carbon units skyrockets unexpectedly, the result isn’t always a shift toward green energy. Instead, it can lead to “significant economic harm,” including the possibility of factory closures. In such a scenario, companies may simply stop operating rather than finding the capital to invest in expensive decarbonization technology.
The Confidence Gap and Agricultural Emissions
A market is only as strong as the confidence of its participants. Currently, that confidence is wavering. Scott Burnett, a climate spokesperson for Forest and Bird, has expressed fears that the scheme is becoming “unfit for purpose.”
The erosion of trust isn’t just about price swings; it’s about policy consistency. Recent government decisions—specifically the rolling back of action on agricultural emissions—have sent mixed signals to the market. When policy pivots sharply, investors lose the certainty they need to commit to long-term sustainable transitions.
For the ETS to function, there must be a clear, unwavering signal that the cost of polluting will continue to rise, regardless of the political climate. Without this stability, the “market” becomes a gamble rather than a strategic tool.
The Path to Reform: What Happens Next?
The solution to a failing scheme isn’t to scrap it, but to refine it. The Climate Change Commission suggests that the government can get ahead of potential shortfalls by engaging in public consultation on options to address the unit supply.
Climate Minister Simon Watts has stated that the government welcomes the commission’s advice and will consider it while developing latest proposals for ETS auction and unit settings. The focus now shifts to whether these proposals will be aggressive enough to prevent the predicted failure by the 2030s.

Frequently Asked Questions
What is an Emissions Trading Scheme (ETS)?
An ETS is a market-based approach to controlling pollution. The government sets a limit (cap) on emissions and issues permits (units). Companies that emit less can sell their extra units to companies that emit more, creating a financial incentive to reduce pollution.
Why is the ETS described as being “on track to fail”?
The Climate Change Commission warns that without reform, the scheme faces extreme volatility and potential unit shortfalls, which could lead to economic instability and a failure to meet climate goals by the 2030s.
How does a unit shortfall affect businesses?
If there are not enough units available, prices can spike. This can cause financial distress for companies, potentially leading to factory closures instead of the intended investment in green technology.
What role do agricultural emissions play in this?
Changes in how agricultural emissions are handled can impact market confidence. Critics argue that rolling back actions in this sector creates instability and makes the ETS less effective.
