As global leaders convene in the Brazilian Amazon for Cop30, it is vital to evaluate how we are faring together in cutting global greenhouse gas emissions.

In spite of 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 marked the publication of the initial scientific evaluation by the IPCC, which confirmed the threat of anthropogenic climate change. While researchers work on the Seventh Assessment Report, they do so knowing that scientific findings remains eclipsed by political influences. Despite well-intentioned efforts, the world is remains dangerously off track to prevent dangerous global warming.

Record-Breaking CO₂ Levels and Carbon-Based Fuel Dependency

Latest figures indicate that atmospheric carbon dioxide levels reached a record high of 423.9 ppm in the year 2024, with the increase rate from 2023 to 2024 surging by the biggest annual rise since record-keeping started in 1957. According to the international carbon monitoring initiative, 90% of total global CO₂ emissions 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 increase in fossil CO₂ emissions in recent times was driven by higher use of natural gas and petroleum—accounting for more than 50% of global emissions—the use of coal also reached a record high, making up forty-one percent. Despite the previous climate summit's evaluation calling for nations to move beyond carbon fuels, collective plans still aim to extract over twice the quantity of hydrocarbons in the year 2030 than aligns with limiting global warming to 1.5 degrees Celsius, with continued extraction of natural gas justified as a lower emission bridge fuel.

The Mirage of Nature-Based Solutions

Instead of concentrating on financial motivators to accelerate the elimination of fossil fuels, environmental strategies are overly dependent on feelgood nature positive solutions that seek to cancel out carbon emissions by afforestation rather than cutting factory discharges. While conserving, enlarging, and rehabilitating natural carbon sinks like forests and marshes is inherently good, research has shown that there is insufficient territory to reach the worldwide target of carbon neutrality using ecological methods alone.

Roughly 1 billion hectares—a territory larger than the USA—is required to fulfill net zero pledges. Over forty percent of this land would need to be transformed from existing uses like food production to carbon sequestration projects by the year 2060 at an unprecedented rate.

Although this regenerative utopia could be realized, forests take time to mature and are susceptible to fires, so they should not be viewed as a fast or permanent carbon storage solution, particularly in a fast-changing environment. As severe temperatures and aridity engulf larger regions, these sincere attempts could actually go up in smoke.

The Diminishing of Natural Carbon Sinks

Scientific evidence indicates that about half of the total CO₂ emitted annually remains in the atmosphere, while the rest is taken up by seas and land ecosystems. With global heating, these natural carbon sinks are becoming less effective at soaking up CO₂, meaning that more carbon accumulates in the air, further exacerbating 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 Climate Liability and Coming Populations

Achieving net zero by 2050 demands CO2 extraction (CDR), which at present relies almost exclusively on terrestrial methods to soak up excess carbon from the air. Polluters can simply buy carbon credits to compensate for their discharges and continue with business as usual. Meanwhile, the planetary heat imbalance resulting from the combustion of hydrocarbons keeps on further destabilise the global climate system. In effect, we are adding more carbon debt to our planetary credit card, leaving future generations with an unpayable liability.

To limit the magnitude and duration of overshoot the global warming targets, the world eventually needs to surpass the neutralising effect of net zero and start to drawdown cumulative historical emissions to reach a carbon-negative state.

The Political Distortion of Net Zero

According to the latest numbers from the international carbon research group, plant-based carbon removal is currently absorbing the equal of about 5% of yearly CO2 from fuels, while engineered carbon extraction represents only about one-millionth of the CO2 emitted from fossil fuels. More generous sector projections place it at around 0.1% of total global emissions. At the risk of sounding like a heretic, the political distortion of net zero is a deceptive gap that distracts from the scientific imperative to eliminate the primary cause of our overheating planet—carbon-based energy.

The Urgent Need for Concrete Action

While this research-backed truth should dominate talks at Cop30, past events suggests that gradual, cautious steps and deference to politics will prevail. Ambiguous promises of future ambition will keep on delay the pressing requirement for definite short-term measures. Until leaders have the courage to put a price on carbon to terminate the age of hydrocarbons, we are releasing more and more carbon to the air, worsening the physical catastrophe currently happening across the globe.

The dilemma we confront is simple: take real action to the scientific reality of our crisis or suffer the consequences of this profound moral failure for generations ahead.
