While world leaders assemble in the Brazilian Amazon for the 30th UN Climate Change Conference, it is essential to evaluate how we are faring together in lowering worldwide emissions of greenhouse gases.

Despite three decades of UN climate summits, nearly 50% of the carbon dioxide accumulated in the atmosphere since the Industrial Revolution has been emitted since 1990. Incidentally, 1990 marked the publication of the First Assessment Report by the IPCC, which confirmed the danger of anthropogenic climate change. While researchers work on the Seventh Assessment Report, they do so aware that their work remains eclipsed by political agendas. Regardless of sincere attempts, the planet is still far from the path to prevent dangerous global warming.

Record-Breaking CO₂ Levels and Carbon-Based Fuel Dependency

Recent data show that CO₂ concentrations hit a record high of 423.9 ppm in the year 2024, with the growth rate from the previous year surging by the largest yearly increase since modern measurements began in 1957. According to the Global Carbon Project, 90% of worldwide carbon dioxide output in last year came from the combustion of carbon-based energy sources, while the remaining 10% resulted from land-use changes such as forest clearance and forest fires.

Although the increase in carbon emissions from fuels in 2024 was driven by higher use of natural gas and petroleum—representing more than 50% of global emissions—coal burning also reached a historic peak, constituting forty-one percent. In spite of the previous climate summit's evaluation calling for nations to transition away from fossil fuels, collective plans still aim to extract over twice the amount of hydrocarbons in the year 2030 than aligns with keeping global warming to 1.5C, with continued extraction of natural gas rationalized as a less polluting transition fuel.

The Illusion of Nature-Based Solutions

Rather than concentrating on economic incentives to speed up the elimination of fossil fuels, environmental strategies are heavily reliant on feel-good eco-positive approaches that aim to cancel out carbon emissions by afforestation rather than reducing factory discharges. While protecting, enlarging, and rehabilitating natural carbon sinks like forests and wetlands is inherently good, studies has shown that there is insufficient territory to reach the worldwide target of net zero emissions using ecological methods by themselves.

Roughly one billion hectares—an area bigger than the USA—is required to fulfill carbon neutrality commitments. More than 40% of this area would need to be converted from existing uses like agriculture to carbon capture initiatives by the year 2060 at an unprecedented rate.

Even if this regenerative utopia could be realized, woodlands require years to grow and are susceptible to fires, so they should not be viewed as a quick or lasting carbon storage solution, especially in a fast-changing environment. As severe temperatures and dryness affect larger regions, these sincere attempts could literally go up in smoke.

The Weakening of Natural Carbon Sinks

Research data indicates that about 50% of the carbon dioxide released annually stays in the air, while the remainder is absorbed by oceans and land ecosystems. As the planet warms, these environmental absorbers are becoming less effective at soaking up CO₂, meaning that additional CO2 builds up in the air, intensifying global warming. Shifting the reduction responsibility onto the land sector effectively excuses the fossil fuel industry from the urgency to cut pollution in the near future.

The Climate Liability and Future Generations

Reaching carbon neutrality by mid-century requires CO2 extraction (CDR), which currently depends largely on land-based measures to soak up excess carbon from the atmosphere. Polluters can easily buy carbon credits to counterbalance their discharges and proceed with normal operations. Meanwhile, the energy imbalance caused by the combustion of hydrocarbons continues to further destabilise the Earth’s climate. In effect, we are increasing our climate liability to our global account, passing on our descendants with an unpayable liability.

To curb the magnitude and length of exceeding the Paris Agreement temperature goals, the planet ultimately needs to go well beyond 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, vegetation-based CDR is currently capturing the equal of about five percent of annual fossil carbon dioxide emissions, while engineered carbon extraction accounts for only about one-millionth of the CO2 emitted from carbon sources. 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 carbon neutrality is an insidious loophole that takes focus away from the research-based necessity to eradicate the primary cause of our warming world—fossil fuels.

The Urgent Need for Definite Steps

While this scientific reality should dominate discussions at the climate summit, history indicates that gradual, cautious steps and deference to politics will prevail. Ambiguous promises of long-term goals will continue to postpone the pressing requirement for definite short-term measures. Until policymakers have the courage to put a price on carbon to terminate the age of hydrocarbons, we are releasing increasing amounts of CO2 to the atmosphere, worsening the physical catastrophe currently happening all around us.

The challenge we confront is simple: take real action to the evidence-based situation of our predicament or endure the results of this deep ethical lapse for centuries to come.
