As global leaders convene in the Brazilian Amazon for Cop30, it is essential to review how we are faring together in lowering worldwide emissions of greenhouse gases.

Despite three decades of UN climate summits, nearly 50% of the CO2 built up in the atmosphere after the dawn of industrialization has been emitted since 1990. Incidentally, 1990 was the release of the First Assessment Report by the IPCC, which verified the threat of anthropogenic climate change. As scientists work on the Seventh Assessment Report, they do so knowing that scientific findings remains overshadowed by political influences. Despite well-intentioned efforts, the planet is remains far from the path to avert catastrophic climate change.

Unprecedented CO₂ Levels and Fossil Fuel Dependency

Recent data show that atmospheric carbon dioxide levels reached a new peak of 423.9 ppm in 2024, with the growth rate from 2023 to 2024 surging by the largest yearly increase since modern measurements began in the late 1950s. Based on the international carbon monitoring initiative, 90% of worldwide carbon dioxide output in 2024 originated from the combustion of carbon-based energy sources, while the other tenth resulted from land-use changes such as forest clearance and forest fires.

While the increase in fossil CO₂ emissions in 2024 was driven by higher use of gas and oil—representing more than 50% of worldwide discharges—the use of coal also attained a historic peak, making up forty-one percent. Despite Cop28’s global stocktake calling for nations to move beyond fossil fuels, collective plans still aim to extract over twice the quantity of fossil fuels in 2030 than aligns with limiting planet heating to 1.5 degrees Celsius, with continued extraction of gas justified as a less polluting transition fuel.

The Illusion of Eco-Friendly Measures

Instead of concentrating on financial motivators to accelerate the elimination of carbon fuels, environmental strategies are heavily reliant on feelgood nature positive approaches that aim to cancel out CO2 output by afforestation instead of cutting industrial emissions. Although conserving, enlarging, and restoring ecological absorbers like woodlands and wetlands is inherently good, studies has demonstrated that there is insufficient territory to reach the global goal of net zero emissions using ecological methods alone.

Roughly 1 billion hectares—a territory larger than the USA—is required to meet carbon neutrality commitments. Over forty percent of this land would need to be transformed from current applications like food production to carbon sequestration projects by 2060 at an never-before-seen pace.

Although this regenerative utopia could be realized, woodlands require years to grow and are susceptible to fires, so they should not be viewed as a fast or lasting carbon storage solution, especially in a rapidly shifting environment. As severe temperatures and dryness engulf larger regions, these sincere attempts could actually go up in smoke.

The Diminishing of Planetary Absorbers

Research data indicates that about half of the total CO₂ emitted each year remains in the atmosphere, while the remainder is absorbed by oceans and land ecosystems. As the planet warms, these environmental absorbers are losing efficiency at capturing CO₂, which means that additional CO2 builds up in the atmosphere, intensifying climate change. Transferring the mitigation burden onto the land sector effectively excuses the fossil fuel industry from the urgency to reduce emissions any time soon.

The Climate Liability and Coming Populations

Achieving net zero by 2050 requires CO2 extraction (CDR), which currently relies almost exclusively on terrestrial methods to absorb excess carbon from the air. Polluters can easily buy carbon credits to compensate for their emissions and proceed with business as usual. At the same time, the planetary heat imbalance resulting from the combustion of hydrocarbons continues to further disrupt the global climate system. Essentially, we are adding more carbon debt to our global account, leaving future generations with an unpayable liability.

To limit the magnitude and length of exceeding the Paris Agreement temperature goals, the planet ultimately needs to surpass the balancing impact of carbon neutrality and begin to remove past carbon outputs to reach net negative emissions.

The Political Distortion of Net Zero

Based on the latest numbers from the international carbon research group, plant-based carbon removal is currently capturing the equivalent of about five percent of annual fossil carbon dioxide emissions, while engineered carbon extraction represents only about a tiny fraction of the carbon released from fossil fuels. Optimistic industry estimates place it at around zero point one percent of total global emissions. At the risk of sounding like a heretic, the political distortion of carbon neutrality is an insidious loophole that takes focus away from the scientific imperative to eliminate the primary cause of our overheating planet—fossil fuels.

The Urgent Need for Concrete Action

Although this research-backed truth should dominate talks at the climate summit, history suggests that polite incrementalism and deference to politics will prevail. Vague statements of long-term goals will continue to postpone the urgent need for definite short-term measures. Unless leaders are brave enough to implement carbon pricing to bring the era of fossil fuels to a definitive end, we are adding more and more carbon to the air, worsening the environmental disaster currently happening across the globe.

The dilemma we confront is straightforward: genuinely respond to the evidence-based situation of our predicament or endure the consequences of this deep ethical lapse for centuries to come.
