As global leaders convene in Brazil for the 30th UN Climate Change Conference, it is crucial to review our collective progress in reducing worldwide emissions of greenhouse gases.

Despite 30 years 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 marked the release of the First Assessment Report by the IPCC, which confirmed the danger of human-caused global warming. While researchers prepare the upcoming IPCC report, they do so knowing that their work remains eclipsed by political agendas. Regardless of well-intentioned efforts, the world is still dangerously off track to avert dangerous global warming.

Record-Breaking CO₂ Levels and Carbon-Based Fuel Dependency

Recent data show that CO₂ concentrations hit a record high of 423.9 parts per million in 2024, with the growth rate from 2023 to 2024 jumping by the largest yearly increase since modern measurements began in 1957. According to the international carbon monitoring initiative, 90% of worldwide carbon dioxide output in 2024 came from the combustion of carbon-based energy sources, 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 higher use of gas and oil—representing over half of worldwide discharges—the use of coal also attained a historic peak, constituting 41%. In spite of Cop28’s global stocktake urging nations to move beyond fossil fuels, collective plans still intend to produce more than double the quantity of hydrocarbons in 2030 than aligns with keeping global warming to 1.5C, with continued extraction of gas rationalized as a lower emission transition fuel.

The Mirage of Eco-Friendly Measures

Instead of concentrating on economic incentives to accelerate the elimination of carbon fuels, climate policies are overly dependent on feelgood nature positive approaches that seek to cancel out carbon emissions by afforestation rather than cutting factory discharges. Although protecting, enlarging, and rehabilitating 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 ecological methods alone.

Approximately 1 billion hectares—an area bigger than the USA—is required to fulfill net zero pledges. Over forty percent of this area would need to be converted from current applications like food production to carbon capture initiatives by the year 2060 at an never-before-seen pace.

Although this regenerative utopia could be realized, woodlands require years to grow and can burn down, so they should not be viewed as a quick or permanent CO2 retention method, especially in a rapidly shifting environment. While severe temperatures and aridity affect more of the planet, these well-intentioned efforts could literally go up in smoke.

The Weakening of Planetary Absorbers

Scientific evidence indicates that about half of the total CO₂ emitted each year stays in the air, while the rest is absorbed by seas and terrestrial systems. With global heating, these environmental absorbers are becoming less effective at capturing CO₂, meaning that more carbon builds up in the atmosphere, intensifying climate change. Transferring the reduction responsibility onto the land sector simply relieves the fossil fuel industry from the pressure to cut pollution in the near future.

The Climate Liability and Future Generations

Achieving net zero by 2050 requires carbon dioxide removal (CDR), which at present relies almost exclusively on terrestrial methods to absorb excess carbon from the air. Polluters can easily buy carbon credits to compensate for their discharges and continue with normal operations. Meanwhile, the planetary heat imbalance resulting from the combustion of hydrocarbons continues to further destabilise the global climate system. In effect, we are increasing our climate liability to our planetary credit card, passing on future generations with an insurmountable burden.

To limit the scale and length of overshoot the Paris Agreement temperature goals, the planet ultimately needs to go well beyond the balancing impact of carbon neutrality and begin to remove past carbon outputs to reach a carbon-negative state.

The Policy Misrepresentation of Net Zero

Based on the most recent data from the Global Carbon Project, vegetation-based CDR is presently absorbing the equal of about 5% of annual fossil carbon dioxide emissions, while engineered carbon extraction represents only about a tiny fraction of the CO2 emitted from fossil fuels. More generous 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 main source of our overheating planet—fossil fuels.

The Critical Requirement for Definite Steps

While this scientific reality should dominate discussions at the climate summit, history suggests that gradual, cautious steps and political kowtowing will prevail. Vague statements of future ambition will keep on postpone the urgent need for concrete immediate action. Until leaders are brave enough to put a price on carbon to terminate the age of hydrocarbons, we are releasing more and more carbon to the atmosphere, compounding the environmental disaster now unfolding across the globe.

The dilemma we confront is straightforward: genuinely respond to the scientific reality of our crisis or endure the consequences of this deep ethical lapse for generations ahead.
