While world leaders convene in the Brazilian Amazon for Cop30, it is essential to assess our collective progress in reducing worldwide emissions of greenhouse gases.

In spite of 30 years of United Nations climate conferences, approximately half of the carbon dioxide accumulated in the atmosphere since the Industrial Revolution has been emitted after the year 1990. Incidentally, 1990 was the release of the initial scientific evaluation by the IPCC, which verified the danger of human-caused global warming. As scientists prepare the upcoming IPCC report, they do so knowing that scientific findings remains eclipsed by political agendas. Despite sincere attempts, the planet is still far from the path to avert catastrophic climate change.

Record-Breaking CO₂ Levels and Fossil Fuel Dependency

Latest figures indicate that CO₂ concentrations reached a record high of 423.9 parts per million in the year 2024, with the increase rate from the previous year surging by the biggest annual rise since record-keeping started in the late 1950s. Based on the international carbon monitoring initiative, 90% 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 wildfires.

Although the rise in fossil CO₂ emissions in recent times was propelled by higher use of gas and oil—representing over half of worldwide discharges—the use of coal also attained a record high, constituting 41%. In spite of the previous climate summit's evaluation urging nations to move beyond fossil fuels, collective plans still intend to produce more than double the amount of hydrocarbons in 2030 than is consistent with keeping planet heating to 1.5C, with continued extraction of natural gas justified as a less polluting bridge fuel.

The Mirage of Eco-Friendly Measures

Instead of focusing on financial motivators to accelerate the phase-out of fossil fuels, climate policies are heavily reliant on feel-good nature positive approaches that aim to neutralize carbon emissions by afforestation rather than reducing factory discharges. Although conserving, enlarging, and rehabilitating ecological absorbers like forests and wetlands is inherently good, research has demonstrated that there is not enough land to achieve the worldwide target of carbon neutrality using nature-based solutions by themselves.

Roughly 1 billion hectares—a territory larger than the United States of America—is needed to meet net zero pledges. More than forty percent of this land 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.

Even if this regenerative utopia could be achieved, woodlands require years to grow and can burn down, so they cannot be considered as a fast or lasting carbon storage solution, particularly in a rapidly shifting environment. As extreme heat and aridity engulf larger regions, these sincere attempts could actually be destroyed by fire.

The Diminishing of Planetary Absorbers

Research data indicates that about half of the total CO₂ emitted each year remains in the atmosphere, while the rest is taken up by seas and land ecosystems. With global heating, these natural carbon sinks are losing efficiency at capturing CO₂, which means that more carbon builds up in the air, intensifying global warming. Transferring the reduction responsibility onto the land sector simply relieves the oil and gas sector from the pressure to reduce emissions any time soon.

The Climate Liability and Future Generations

Reaching carbon neutrality by mid-century demands carbon dioxide removal (CDR), which currently relies almost exclusively on land-based measures to soak up surplus CO2 from the air. Polluters can easily purchase offsets to counterbalance their emissions and proceed with business as usual. At the same time, the planetary heat imbalance resulting from the combustion of hydrocarbons keeps on further destabilise the global climate system. Essentially, we are adding more carbon debt to our planetary credit card, leaving our descendants with an insurmountable burden.

To curb the magnitude and duration of exceeding the Paris Agreement temperature goals, the planet eventually needs to go well beyond the neutralising effect of net zero and start to drawdown past carbon outputs to reach a carbon-negative state.

The Political Distortion of Carbon Neutrality

Based on the most recent data from the international carbon research group, vegetation-based CDR is presently capturing the equivalent of about 5% of annual fossil carbon dioxide emissions, while engineered carbon extraction represents only about a tiny fraction of the carbon released from fossil fuels. More generous sector projections suggest around 0.1% of worldwide CO2 output. Without meaning to be controversial, the policy twisting of carbon neutrality is an insidious loophole that takes focus away from the research-based necessity to eliminate the main source of our warming world—carbon-based energy.

The Critical Requirement for Definite Steps

While this research-backed truth should lead talks at the climate summit, history suggests that polite incrementalism and political kowtowing will win out. Vague statements of long-term goals will continue to postpone the urgent need for definite short-term measures. Unless leaders are brave enough to put a price on carbon to bring the era of fossil fuels to a definitive end, we are adding more and more carbon to the atmosphere, worsening the physical catastrophe currently happening all around us.

The dilemma we confront is simple: genuinely respond to the scientific reality of our predicament or suffer the consequences of this profound moral failure for generations ahead.
