While world leaders assemble in Brazil for the 30th UN Climate Change Conference, it is vital to evaluate how we are faring together in cutting global greenhouse gas emissions.

In spite of three decades of UN climate summits, nearly 50% of the carbon dioxide accumulated in the atmosphere since the Industrial Revolution has been emitted after the year 1990. Coincidentally, 1990 marked the release of the First Assessment Report by the Intergovernmental Panel on Climate Change, which confirmed the danger of human-caused global warming. As scientists prepare the Seventh Assessment Report, they do so aware that their work remains eclipsed by political agendas. Regardless of well-intentioned efforts, the planet is still far from the path to avert dangerous global warming.

Unprecedented CO₂ Levels and Carbon-Based Fuel Dependency

Latest figures indicate that atmospheric carbon dioxide levels reached a new peak of 423.9 ppm in the year 2024, with the growth rate from the previous year jumping by the biggest annual rise since modern measurements began in 1957. According to the international carbon monitoring initiative, ninety percent of worldwide carbon dioxide output in 2024 originated from the combustion of carbon-based energy sources, while the remaining 10% resulted from alterations in land use such as deforestation and forest fires.

Although the rise in carbon emissions from fuels in recent times was propelled by increased use of gas and oil—accounting for more than 50% of worldwide discharges—coal burning also attained a historic peak, constituting forty-one percent. In spite of Cop28’s global stocktake calling for nations to transition away from carbon fuels, collective plans still intend to extract over twice the amount of hydrocarbons in the year 2030 than aligns with keeping planet heating to 1.5 degrees Celsius, with continued extraction of natural gas rationalized as a lower emission bridge fuel.

The Illusion of Nature-Based Solutions

Rather than concentrating on economic incentives to speed up the elimination of carbon fuels, climate policies are heavily reliant on feel-good nature positive solutions that aim to cancel out carbon emissions by planting trees rather than cutting industrial emissions. While protecting, enlarging, and restoring ecological absorbers like forests and marshes is beneficial in itself, studies has demonstrated that there is insufficient territory to reach the worldwide target of net zero emissions using nature-based solutions alone.

Approximately one billion hectares—a territory larger than the USA—is needed to fulfill carbon neutrality commitments. Over 40% of this land would need to be converted from existing uses like agriculture to carbon sequestration projects by 2060 at an never-before-seen pace.

Even if this regenerative utopia could be realized, woodlands take time to mature and can burn down, so they should not be viewed as a quick or permanent CO2 retention method, particularly in a fast-changing climate. As severe temperatures and aridity engulf more of the planet, these well-intentioned efforts could literally be destroyed by fire.

The Diminishing of Planetary Absorbers

Scientific evidence indicates that about 50% of the carbon dioxide released each year remains in the atmosphere, while the remainder is taken up by oceans and land ecosystems. As the planet warms, these natural carbon sinks are losing efficiency at capturing CO₂, meaning that additional CO2 builds up in the air, intensifying global warming. Shifting the mitigation burden onto the land sector effectively excuses the fossil fuel industry from the urgency to cut pollution any time soon.

The Carbon Debt and Future Generations

Achieving net zero by 2050 demands CO2 extraction (CDR), which currently relies almost exclusively on land-based measures to absorb excess carbon from the atmosphere. Emitting companies can easily buy carbon credits to counterbalance their emissions and continue with normal operations. At the same time, the energy imbalance resulting from the combustion of hydrocarbons keeps on further disrupt the Earth’s climate. In effect, we are adding more carbon debt to our global account, leaving future generations with an insurmountable burden.

To limit the magnitude and duration of exceeding the global warming targets, the world ultimately needs to surpass the neutralising effect of net zero and start to remove cumulative historical emissions to achieve a carbon-negative state.

The Policy Misrepresentation of Carbon Neutrality

According to the most recent data from the international carbon research group, plant-based carbon removal is currently capturing the equal of about 5% of annual fossil carbon dioxide emissions, while engineered carbon extraction accounts for only about one-millionth of the CO2 emitted from carbon sources. Optimistic industry estimates place it at around zero point one percent of worldwide CO2 output. At the risk of sounding like a heretic, the political distortion of carbon neutrality is an insidious loophole 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 Definite Steps

While this research-backed truth should dominate discussions at Cop30, past events suggests that gradual, cautious steps and deference to politics will win out. Vague statements of future ambition will keep on delay the urgent need for definite short-term measures. Until policymakers are brave enough to put a price on carbon to terminate the age of hydrocarbons, we are releasing more and more carbon to the air, worsening the environmental disaster currently happening all around us.

The dilemma we face is straightforward: take real action to the scientific reality of our predicament or suffer the consequences of this deep ethical lapse for generations ahead.
