As global leaders convene in the Brazilian Amazon for Cop30, it is vital to evaluate our collective progress in reducing worldwide emissions of greenhouse gases.

In spite of three decades of United Nations climate conferences, approximately half of the CO2 built up in the atmosphere after the dawn of industrialization has been emitted since 1990. Incidentally, 1990 was the release of the initial scientific evaluation by the Intergovernmental Panel on Climate Change, which verified the danger of anthropogenic climate change. While researchers work on the Seventh Assessment Report, they do so knowing that their work remains eclipsed by political influences. Regardless of well-intentioned efforts, the world is still dangerously off track to avert catastrophic climate change.

Unprecedented CO₂ Levels and Carbon-Based Fuel Dependency

Recent data show that CO₂ concentrations reached a record high of 423.9 ppm in 2024, with the increase rate from the previous year surging by the biggest annual rise since modern measurements began in the late 1950s. Based on the international carbon monitoring initiative, ninety percent of worldwide carbon dioxide output in 2024 came from burning fossil fuels, while the other tenth resulted from alterations in land use such as deforestation and forest fires.

Although the increase in carbon emissions from fuels in recent times was propelled by increased use of natural gas and petroleum—accounting for over half of global emissions—the use of coal also attained a historic peak, constituting 41%. In spite of Cop28’s global stocktake urging nations to transition away from fossil fuels, collective plans still intend to produce more than double the amount of fossil fuels in 2030 than aligns with keeping planet heating to 1.5 degrees Celsius, with ongoing drilling of natural gas justified as a less polluting bridge fuel.

The Illusion of Eco-Friendly Measures

Instead of concentrating on financial motivators to speed up the elimination of fossil fuels, climate policies are heavily reliant on feelgood eco-positive solutions that seek to neutralize CO2 output by planting trees rather than cutting industrial emissions. While protecting, enlarging, and restoring ecological absorbers like forests and wetlands is beneficial in itself, research has shown that there is insufficient territory to achieve the worldwide target of carbon neutrality using nature-based solutions by themselves.

Roughly one billion hectares—an area bigger than the USA—is required to fulfill carbon neutrality commitments. Over 40% of this land would need to be transformed from existing uses like food production to carbon sequestration projects by 2060 at an unprecedented rate.

Even if this ideal restoration could be realized, forests require years to grow and can burn down, so they cannot be considered as a fast or permanent carbon storage solution, especially in a rapidly shifting climate. As extreme heat and aridity engulf larger regions, these sincere attempts could literally go up in smoke.

The Diminishing of Planetary Absorbers

Scientific evidence tells us that about 50% of the carbon dioxide released each year stays in the air, while the rest is absorbed by seas and land ecosystems. As the planet warms, these natural carbon sinks are becoming less effective at capturing CO₂, which means that more carbon builds up in the air, further exacerbating global warming. Transferring the mitigation burden onto the agricultural and forest sectors effectively excuses the oil and gas sector from the urgency to reduce emissions in the near future.

The Climate Liability and Future Generations

Reaching carbon neutrality by mid-century requires CO2 extraction (CDR), which currently relies almost exclusively on terrestrial methods to soak up excess carbon from the atmosphere. Emitting companies can simply purchase offsets to counterbalance their emissions and continue with business as usual. At the same time, the energy imbalance caused by the burning of fossil fuels keeps on further disrupt the Earth’s climate. Essentially, we are adding more carbon debt to our planetary credit card, passing on our descendants with an unpayable liability.

To curb the magnitude and length of overshoot the Paris Agreement temperature goals, the world eventually needs to go well beyond the neutralising effect of net zero and begin to drawdown cumulative historical emissions to reach net negative emissions.

The Policy Misrepresentation of Net Zero

According to the most recent data from the international carbon research group, plant-based carbon removal is presently absorbing the equivalent of about 5% of yearly CO2 from fuels, while technology-based CDR represents only about a tiny fraction of the carbon released from carbon sources. More generous industry estimates place it at around 0.1% of total global emissions. Without meaning to be controversial, the political distortion of net zero is an insidious loophole that takes focus away from the research-based necessity to eliminate the main source of our overheating planet—fossil fuels.

The Urgent Need for Concrete Action

While this research-backed truth should dominate talks at Cop30, history indicates that gradual, cautious steps and political kowtowing will prevail. Vague statements of long-term goals will keep on delay the urgent need for concrete immediate action. Unless policymakers have the courage to implement carbon pricing to bring the era of fossil fuels to a definitive end, we are adding increasing amounts of CO2 to the air, worsening the physical catastrophe currently happening across the globe.

The challenge we confront is straightforward: genuinely respond to the evidence-based situation of our predicament or endure the consequences of this deep ethical lapse for centuries to come.
