As global leaders assemble in Brazil for Cop30, it is crucial to evaluate how we are faring together in reducing worldwide emissions of greenhouse gases.

Despite 30 years of UN climate summits, approximately half of the CO2 built up in the atmosphere after the dawn of industrialization has been released after the year 1990. Incidentally, 1990 was the release of the initial scientific evaluation by the IPCC, which confirmed the danger of anthropogenic climate change. While researchers prepare the Seventh Assessment Report, they do so aware that scientific findings remains overshadowed by political influences. Regardless of sincere attempts, the planet is remains dangerously off track 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 ppm in 2024, with the increase rate from 2023 to 2024 jumping 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 came from burning fossil fuels, while the remaining 10% resulted from land-use changes such as deforestation and forest fires.

While the rise in carbon emissions from fuels in recent times was propelled by increased use of gas and oil—accounting for over half of global emissions—the use of coal also reached a record high, constituting 41%. In spite of the previous climate summit's evaluation calling for nations to transition away from fossil fuels, collective plans still aim to produce more than double the amount of hydrocarbons in the year 2030 than is consistent with keeping planet heating to 1.5C, with continued extraction of gas rationalized as a lower emission bridge fuel.

The Mirage of Nature-Based Solutions

Instead of focusing on financial motivators to speed up the elimination of fossil fuels, environmental strategies are heavily reliant on feel-good nature positive solutions that seek to neutralize CO2 output by planting trees rather than reducing factory discharges. Although protecting, expanding, and rehabilitating natural carbon sinks like forests and wetlands is inherently good, research has demonstrated that there is not enough land to reach the worldwide target of carbon neutrality using ecological methods by themselves.

Approximately 1 billion hectares—an area larger than the United States of America—is needed to meet carbon neutrality commitments. More than 40% of this land would need to be transformed from existing uses like agriculture to carbon capture initiatives by 2060 at an never-before-seen pace.

Although this ideal restoration could be realized, woodlands require years to grow and can burn down, so they cannot be considered as a quick or permanent carbon storage solution, particularly in a fast-changing climate. While extreme heat and dryness engulf larger regions, these well-intentioned efforts could actually be destroyed by fire.

The Weakening of Natural Carbon Sinks

Research data tells us that about 50% of the total CO₂ emitted annually stays in the air, while the remainder is taken up by seas and terrestrial systems. As the planet warms, these environmental absorbers are becoming less effective at capturing CO₂, meaning that more carbon builds up 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 reduce emissions 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 soak up excess carbon from the atmosphere. Polluters can easily buy carbon credits to counterbalance their emissions and proceed with business as usual. At the same time, the energy imbalance caused by the combustion of hydrocarbons keeps on further destabilise the Earth’s climate. In effect, we are increasing our climate liability to our planetary credit card, passing on our descendants with an insurmountable burden.

To curb the scale and length of overshoot the Paris Agreement temperature goals, the world eventually needs to surpass the balancing impact of net zero and start to drawdown cumulative historical emissions to reach a carbon-negative state.

The Policy Misrepresentation of Carbon Neutrality

Based on the latest numbers from the Global Carbon Project, vegetation-based CDR is currently capturing the equivalent of about 5% of annual fossil carbon dioxide emissions, while technology-based CDR represents only about a tiny fraction of the carbon released from carbon sources. Optimistic sector projections place it at 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 eradicate the main source of our warming world—fossil fuels.

The Critical Requirement for Concrete Action

Although this scientific reality should dominate talks at the climate summit, history suggests that gradual, cautious steps and political kowtowing will prevail. Ambiguous promises of future ambition will continue to postpone the urgent need for concrete immediate action. Unless policymakers are brave enough to put a price on carbon to terminate the age of hydrocarbons, we are releasing more and more carbon to the air, compounding the physical catastrophe currently happening all around us.

The challenge we face is straightforward: take real action to the scientific reality of our crisis or suffer the consequences of this profound moral failure for centuries to come.
