While world leaders convene in the Brazilian Amazon for Cop30, it is vital to assess how we are faring together in cutting worldwide emissions of greenhouse gases.

In spite of 30 years of United Nations climate conferences, nearly 50% of the CO2 built up in the atmosphere after the dawn of industrialization has been released after the year 1990. Coincidentally, 1990 was the publication of the First Assessment Report by the Intergovernmental Panel on Climate Change, which confirmed the danger of anthropogenic climate change. While researchers prepare the upcoming IPCC report, they do so knowing that their work remains overshadowed by political agendas. Despite sincere attempts, the planet is remains far from the path to avert dangerous global warming.

Record-Breaking CO₂ Levels and Fossil Fuel Dependency

Latest figures indicate that atmospheric carbon dioxide levels hit a new peak of 423.9 parts per million in the year 2024, with the growth rate from 2023 to 2024 jumping by the largest yearly increase 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 remaining 10% was due to alterations in land use such as deforestation and forest fires.

While the increase in fossil CO₂ emissions in recent times was propelled by increased use of gas and oil—representing more than 50% of global emissions—the use of coal also reached a record high, making up 41%. Despite the previous climate summit's evaluation urging nations to move beyond carbon fuels, collective plans still intend to extract over twice the quantity of fossil fuels in 2030 than is consistent with keeping global warming to 1.5C, with continued extraction of gas justified as a lower emission bridge fuel.

The Illusion of Nature-Based Solutions

Rather than focusing on financial motivators to accelerate the elimination of carbon fuels, climate policies are overly dependent on feelgood eco-positive solutions that seek to neutralize carbon emissions by afforestation instead of cutting factory discharges. While conserving, enlarging, and rehabilitating natural carbon sinks like forests and marshes is inherently good, research has demonstrated that there is insufficient territory to achieve the worldwide target of net zero emissions using nature-based solutions by themselves.

Approximately one billion hectares—an area larger than the USA—is needed to fulfill carbon neutrality commitments. Over 40% of this area would need to be transformed from current applications like agriculture to carbon capture initiatives by the year 2060 at an never-before-seen pace.

Even if this regenerative utopia 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 dryness affect larger regions, these well-intentioned efforts could literally be destroyed by fire.

The Weakening of Planetary Absorbers

Research data tells us that about half of the carbon dioxide released each year stays in the air, while the rest is taken up by seas and terrestrial systems. As the planet warms, these environmental absorbers are becoming less effective at capturing CO₂, meaning that additional CO2 accumulates in the air, further exacerbating global warming. Transferring the reduction responsibility onto the land sector simply relieves the oil and gas sector from the urgency to cut pollution in the near future.

The Climate Liability and Coming Populations

Achieving carbon neutrality by mid-century demands carbon dioxide removal (CDR), which currently depends largely on land-based measures to soak up surplus CO2 from the air. Polluters can simply purchase offsets to compensate for their emissions and continue with business as usual. At the same time, the planetary heat imbalance caused by the burning of fossil fuels continues to further disrupt the Earth’s climate. In effect, we are increasing our climate liability to our global account, passing on future generations with an insurmountable burden.

To limit the magnitude and length of exceeding the global warming targets, the planet ultimately needs to go well beyond the balancing impact of carbon neutrality and begin to drawdown cumulative historical emissions to achieve a carbon-negative state.

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 equivalent of about five percent of annual fossil carbon dioxide emissions, while engineered carbon extraction accounts for only about a tiny fraction of the CO2 emitted from fossil fuels. More generous industry estimates suggest around zero point one percent of total global emissions. Without meaning to be controversial, the policy twisting of carbon neutrality is an insidious loophole that distracts from the scientific imperative to eliminate the primary cause of our overheating planet—fossil fuels.

The Urgent Need for Definite Steps

Although this research-backed truth should dominate discussions at the climate summit, past events indicates that gradual, cautious steps and deference to politics will prevail. Vague statements of future ambition will continue to postpone the pressing requirement for definite short-term measures. Unless leaders have the courage to put a price on carbon to terminate the age of hydrocarbons, we are adding increasing amounts of CO2 to the air, compounding the physical catastrophe currently happening across the globe.

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