As global leaders assemble in the Brazilian Amazon for the 30th UN Climate Change Conference, it is essential to assess how we are faring together in cutting worldwide emissions of greenhouse gases.

Despite 30 years of United Nations climate conferences, nearly 50% of the carbon dioxide accumulated in the atmosphere since the Industrial Revolution has been emitted after the year 1990. Coincidentally, 1990 was the release of the First Assessment Report by the Intergovernmental Panel on Climate Change, which verified the danger of anthropogenic climate change. While researchers prepare the upcoming IPCC report, they do so aware that scientific findings remains eclipsed by political influences. Regardless of sincere attempts, the world is still far from the path to prevent catastrophic climate change.

Record-Breaking CO₂ Levels and Carbon-Based Fuel Dependency

Latest figures indicate that CO₂ concentrations hit a new peak of 423.9 parts per million in the year 2024, with the increase rate from the previous year surging by the largest yearly increase since modern measurements began in the late 1950s. Based on the international carbon monitoring initiative, 90% of worldwide carbon dioxide output in last year came from burning fossil fuels, while the remaining 10% resulted from alterations in land use such as deforestation and forest fires.

While the rise in carbon emissions from fuels in 2024 was propelled by increased use of natural gas and petroleum—accounting for over half of worldwide discharges—the use of coal also reached a record high, constituting forty-one percent. In spite of Cop28’s global stocktake calling for nations to transition away from carbon fuels, global strategies still aim to produce more than double the amount of hydrocarbons in 2030 than aligns with keeping global warming to 1.5 degrees Celsius, with continued extraction of gas justified as a lower emission transition fuel.

The Mirage of Eco-Friendly Measures

Rather than focusing on economic incentives to accelerate the elimination of carbon fuels, environmental strategies are heavily reliant on feel-good nature positive approaches that aim to cancel out CO2 output by afforestation rather than reducing factory discharges. While conserving, enlarging, and restoring ecological absorbers like woodlands and marshes is inherently good, studies has demonstrated that there is not enough land to reach the worldwide target of carbon neutrality using ecological methods by themselves.

Approximately 1 billion hectares—an area larger than the United States of America—is required to fulfill carbon neutrality commitments. More than forty percent of this land would need to be transformed from existing uses like food production to carbon sequestration projects by 2060 at an unprecedented rate.

Although this ideal restoration could be realized, woodlands take time to mature and can burn down, so they should not be viewed as a quick or lasting carbon storage solution, especially in a fast-changing climate. As extreme heat and aridity affect larger regions, these well-intentioned efforts could literally go up in smoke.

The Diminishing of Natural Carbon Sinks

Scientific evidence indicates that about 50% of the carbon dioxide released each year remains in the atmosphere, while the remainder is taken up by seas and terrestrial systems. As the planet warms, these natural carbon sinks are losing efficiency at soaking up CO₂, which means that more carbon accumulates in the air, further exacerbating global warming. Shifting the reduction responsibility onto the land sector simply relieves the fossil fuel industry from the pressure to cut pollution any time soon.

The Carbon Debt and Future Generations

Achieving carbon neutrality by mid-century demands carbon dioxide removal (CDR), which at present depends largely on land-based measures to absorb surplus CO2 from the air. Polluters can simply buy carbon credits to compensate for their emissions and proceed with normal operations. At the same time, the energy imbalance resulting from the combustion of hydrocarbons continues to further destabilise the Earth’s climate. In effect, we are adding more carbon debt to our planetary credit card, leaving future generations with an insurmountable burden.

To limit the scale and duration of exceeding the Paris Agreement temperature goals, the world ultimately needs to go well beyond the neutralising effect of carbon neutrality and start to drawdown past carbon outputs to reach net negative emissions.

The Political Distortion of Net Zero

Based on the most recent data from the Global Carbon Project, vegetation-based CDR is presently capturing the equivalent of about five percent of yearly CO2 from fuels, while engineered carbon extraction represents only about one-millionth of the carbon released from fossil fuels. Optimistic sector projections place it at around zero point one percent of total global emissions. At the risk of sounding like a heretic, the political distortion of carbon neutrality is a deceptive gap that takes focus away from the research-based necessity to eliminate the primary cause of our overheating planet—carbon-based energy.

The Urgent Need for Concrete Action

Although this scientific reality should dominate discussions at Cop30, past events indicates that polite incrementalism and deference to politics will prevail. Ambiguous promises of future ambition will continue to postpone the urgent need for definite short-term measures. Unless policymakers have the courage to put a price on carbon to terminate the age of hydrocarbons, we are adding increasing amounts of CO2 to the atmosphere, worsening the physical catastrophe currently happening all around us.

The dilemma we confront is simple: take real action to the evidence-based situation of our crisis or endure the consequences of this deep ethical lapse for centuries to come.
