As global leaders convene in Brazil for Cop30, it is crucial to evaluate how we are faring together in lowering global greenhouse gas emissions.

In spite of 30 years of UN climate summits, approximately half of the CO2 built up in the atmosphere since the Industrial Revolution has been emitted since 1990. Incidentally, 1990 was 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 aware that scientific findings remains overshadowed by political influences. Despite sincere attempts, the world is still far from the path to avert catastrophic climate change.

Unprecedented CO₂ Levels and Carbon-Based Fuel Dependency

Recent data show that atmospheric carbon dioxide levels reached a record high of 423.9 ppm in the year 2024, with the growth rate from 2023 to 2024 surging by the biggest annual rise since record-keeping started in the late 1950s. According to the international carbon monitoring initiative, 90% of worldwide carbon dioxide output in last year came from the combustion of carbon-based energy sources, while the other tenth was due to land-use changes such as deforestation and forest fires.

Although the rise 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 historic peak, constituting 41%. In spite of Cop28’s global stocktake urging nations to move beyond carbon fuels, collective plans still intend to extract over twice the amount of hydrocarbons in the year 2030 than aligns with limiting global warming to 1.5 degrees Celsius, with ongoing drilling of gas justified as a lower emission transition fuel.

The Illusion of Nature-Based Solutions

Rather than concentrating on economic incentives to accelerate the phase-out of carbon fuels, climate policies are overly dependent on feelgood nature positive solutions that aim to neutralize carbon emissions by afforestation instead of cutting industrial emissions. Although protecting, enlarging, and restoring ecological absorbers like woodlands and marshes is inherently good, research has shown that there is insufficient territory to achieve the worldwide target of net zero emissions using ecological methods alone.

Roughly 1 billion hectares—an area larger than the United States of America—is needed to fulfill net zero pledges. More than 40% of this land would need to be converted from existing uses like food production to carbon capture initiatives by the year 2060 at an never-before-seen pace.

Even if this ideal restoration could be achieved, woodlands take time to mature and are susceptible to fires, so they should not be viewed as a quick or permanent CO2 retention method, especially in a fast-changing environment. As severe temperatures and dryness engulf more of the planet, these well-intentioned efforts could actually be destroyed by fire.

The Diminishing of Natural Carbon Sinks

Scientific evidence tells us that about 50% of the carbon dioxide released annually remains in the atmosphere, while the remainder is taken up by seas and terrestrial systems. With global heating, these natural carbon sinks are becoming less effective at capturing CO₂, which means that additional CO2 builds up in the air, intensifying climate change. 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 Future Generations

Reaching net zero by 2050 requires CO2 extraction (CDR), which currently relies almost exclusively on terrestrial methods to absorb surplus CO2 from the air. Polluters can simply purchase offsets to compensate for their discharges and continue with business as usual. At the same time, the energy imbalance caused by the combustion of hydrocarbons keeps on further disrupt the Earth’s climate. In effect, we are increasing our climate liability to our planetary credit card, leaving our descendants with an unpayable liability.

To limit the magnitude and length of overshoot the Paris Agreement temperature goals, the world ultimately needs to surpass the balancing impact of carbon neutrality and begin to drawdown past carbon outputs to achieve net negative emissions.

The Policy Misrepresentation of Net Zero

According to the latest numbers from the Global Carbon Project, plant-based carbon removal is presently absorbing the equal of about 5% of annual fossil carbon dioxide emissions, while technology-based CDR accounts for only about one-millionth of the carbon released from fossil fuels. Optimistic industry estimates place it at around 0.1% of worldwide CO2 output. Without meaning to be controversial, the policy twisting of carbon neutrality is a deceptive gap that takes focus away from the scientific imperative to eradicate the primary cause of our warming world—fossil fuels.

The Critical Requirement for Concrete Action

Although this research-backed truth should lead talks at Cop30, past events suggests that polite incrementalism and deference to politics will win out. Ambiguous promises of future ambition will keep on delay the urgent need for concrete immediate action. Until policymakers are brave enough to put a price on carbon to bring the era of fossil fuels to a definitive end, we are adding increasing amounts of CO2 to the air, compounding the environmental disaster currently happening all around us.

The challenge we confront is simple: genuinely respond to the evidence-based situation of our predicament or endure the consequences of this profound moral failure for centuries to come.
