As global leaders gather in the Brazilian Amazon for Cop30, it is vital to assess our collective progress in reducing global greenhouse gas emissions.

Despite 30 years of United Nations climate conferences, approximately half of the carbon dioxide accumulated in the atmosphere after the dawn of industrialization has been emitted since 1990. Incidentally, 1990 was the release of the First Assessment Report by the Intergovernmental Panel on Climate Change, which confirmed the danger of anthropogenic climate change. While researchers prepare the Seventh Assessment Report, they do so aware that their work remains eclipsed by political influences. Regardless of sincere attempts, the world is remains dangerously off track to prevent catastrophic climate change.

Record-Breaking CO₂ Levels and Fossil Fuel Dependency

Recent data indicate that atmospheric carbon dioxide levels hit a record high of 423.9 parts per million in 2024, with the increase rate from 2023 to 2024 jumping by the largest yearly increase since record-keeping started in 1957. According to the international carbon monitoring initiative, 90% of worldwide carbon dioxide output in last year originated from burning fossil fuels, while the remaining 10% was due to land-use changes such as deforestation and forest fires.

Although the rise in carbon emissions from fuels in recent times was propelled by higher use of gas and oil—accounting for more than 50% of worldwide discharges—coal burning also reached a record high, constituting forty-one percent. In spite of Cop28’s global stocktake urging nations to transition away from fossil fuels, global strategies still aim to produce more than double the quantity of fossil fuels in the year 2030 than is consistent with limiting planet heating to 1.5C, with continued extraction of gas justified as a less polluting bridge fuel.

The Mirage of Eco-Friendly Measures

Rather than concentrating on economic incentives to accelerate the phase-out of fossil fuels, climate policies are overly dependent on feelgood nature positive approaches that aim to cancel out CO2 output by planting trees rather than cutting factory discharges. Although protecting, enlarging, and restoring natural carbon sinks like woodlands and wetlands is beneficial in itself, research has demonstrated that there is not enough land to achieve the global goal of net zero emissions using ecological methods by themselves.

Roughly one billion hectares—an area bigger than the United States of America—is required to meet net zero pledges. More than forty percent of this area would need to be transformed from existing uses like agriculture to carbon sequestration projects by the year 2060 at an unprecedented rate.

Even if this regenerative utopia could be realized, woodlands take time to mature and are susceptible to fires, so they cannot be considered as a quick or permanent carbon storage solution, especially in a rapidly shifting climate. While severe temperatures and aridity affect more of the planet, these sincere attempts could actually go up in smoke.

The Weakening of Natural Carbon Sinks

Research data indicates that about 50% of the carbon dioxide released annually stays in the air, while the rest is taken up by seas and terrestrial systems. As the planet warms, these natural carbon sinks are becoming less effective at soaking up CO₂, meaning that additional CO2 accumulates in the air, intensifying global warming. Transferring the reduction responsibility onto the agricultural and forest sectors effectively excuses the fossil fuel industry from the pressure to reduce emissions any time soon.

The Climate Liability and Future Generations

Reaching carbon neutrality by mid-century requires carbon dioxide removal (CDR), which currently depends largely on land-based measures to soak up excess carbon from the atmosphere. Emitting companies can easily buy carbon credits to counterbalance their emissions and proceed with business as usual. At the same time, the planetary heat imbalance resulting from the combustion of hydrocarbons continues to further disrupt the Earth’s climate. In effect, we are increasing our climate liability to our planetary credit card, leaving our descendants with an insurmountable burden.

To limit the scale and duration of exceeding the global warming targets, the world ultimately needs to surpass the balancing impact of carbon neutrality and begin to drawdown cumulative historical emissions to achieve net negative emissions.

The Political Distortion of Carbon Neutrality

According to the most recent data from the international carbon research group, vegetation-based CDR is currently absorbing the equal of about five percent of yearly CO2 from fuels, while technology-based CDR represents only about one-millionth of the carbon released from carbon sources. Optimistic industry estimates suggest around 0.1% of total global emissions. Without meaning to be controversial, the political distortion of net zero is an insidious loophole that distracts from the research-based necessity to eradicate the main source of our warming world—fossil fuels.

The Urgent Need for Concrete Action

While this research-backed truth should dominate talks at the climate summit, past events indicates that polite incrementalism and deference to politics will prevail. Vague statements of future ambition will keep on postpone the pressing requirement for concrete immediate action. Until policymakers are brave enough to implement carbon pricing to bring the era of fossil fuels to a definitive end, we are releasing more and more carbon to the atmosphere, worsening the physical catastrophe currently happening all around us.

The dilemma we confront is straightforward: genuinely respond to the scientific reality of our crisis or suffer the consequences of this profound moral failure for centuries to come.
