As global leaders assemble in Brazil for the 30th UN Climate Change Conference, it is vital to review how we are faring together in cutting global greenhouse gas emissions.

In spite of three decades of United Nations climate conferences, nearly 50% of the CO2 built up in the atmosphere since the Industrial Revolution has been emitted after the year 1990. Coincidentally, 1990 was the publication of the initial scientific evaluation by the Intergovernmental Panel on Climate Change, which confirmed the danger of anthropogenic climate change. While researchers work on the upcoming IPCC report, they do so knowing that scientific findings remains overshadowed by political agendas. Despite sincere attempts, the world is remains dangerously off track to prevent catastrophic climate change.

Unprecedented CO₂ Levels and Carbon-Based Fuel Dependency

Latest figures show that atmospheric carbon dioxide levels reached a new peak of 423.9 ppm in 2024, with the growth rate from the previous year jumping by the biggest annual rise since modern measurements began in 1957. Based on the Global Carbon Project, 90% of worldwide carbon dioxide output in 2024 originated from burning fossil fuels, while the remaining 10% resulted from land-use changes such as deforestation and wildfires.

While the rise in carbon emissions from fuels in recent times was driven by increased use of natural gas and petroleum—accounting for more than 50% of global emissions—coal burning also attained a historic peak, making up 41%. In spite of Cop28’s global stocktake calling for nations to transition away from fossil fuels, global strategies still intend to produce more than double the quantity of hydrocarbons in the year 2030 than aligns with limiting planet heating to 1.5C, with continued extraction of natural gas rationalized as a less polluting bridge fuel.

The Mirage of Nature-Based Solutions

Instead of focusing on economic incentives to speed up the phase-out of carbon fuels, environmental strategies are heavily reliant on feel-good nature positive solutions that seek to cancel out CO2 output by planting trees instead of reducing industrial emissions. Although protecting, enlarging, and restoring ecological absorbers like woodlands and wetlands is inherently good, studies has demonstrated that there is not enough land to reach the worldwide target of carbon neutrality using nature-based solutions by themselves.

Roughly 1 billion hectares—a territory larger than the USA—is required to meet net zero pledges. Over forty percent of this area would need to be transformed from current applications like agriculture to carbon sequestration projects by the year 2060 at an unprecedented rate.

Although this ideal restoration could be realized, woodlands require years to grow and can burn down, so they should not be viewed as a quick or lasting carbon storage solution, particularly in a rapidly shifting climate. While extreme heat and dryness affect more of the planet, these well-intentioned efforts could actually go up in smoke.

The Weakening of Planetary Absorbers

Scientific evidence indicates that about half of the carbon dioxide released each year remains in the atmosphere, while the remainder is taken up by seas and terrestrial systems. As the planet warms, these natural carbon sinks are losing efficiency at soaking up CO₂, meaning that additional CO2 builds up in the air, intensifying climate change. Transferring the mitigation burden onto the agricultural and forest sectors effectively excuses the oil and gas sector from the urgency to cut pollution in the near future.

The Climate Liability and Coming Populations

Achieving carbon neutrality by mid-century requires carbon dioxide removal (CDR), which currently depends largely on land-based measures to soak up excess carbon from the air. Polluters can simply purchase offsets to counterbalance their emissions and continue with business as usual. Meanwhile, the planetary heat imbalance resulting from the combustion of hydrocarbons keeps on further destabilise the global climate system. In effect, we are adding more carbon debt to our global account, passing on future generations with an unpayable liability.

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

The Political Distortion of Carbon Neutrality

Based on the most recent data from the international carbon research group, vegetation-based CDR is presently absorbing the equivalent of about 5% of annual fossil carbon dioxide emissions, while engineered carbon extraction represents only about a tiny fraction of the CO2 emitted from fossil fuels. More generous sector projections place it at around 0.1% of worldwide CO2 output. At the risk of sounding like a heretic, the political distortion of net zero is a deceptive gap that takes focus away from the scientific imperative to eliminate the main source of our warming world—fossil fuels.

The Critical Requirement for Definite Steps

While this scientific reality should lead discussions at Cop30, history suggests that gradual, cautious steps and political kowtowing will win out. Ambiguous promises of future ambition will continue to postpone the pressing requirement for definite short-term measures. Until policymakers are brave enough to implement carbon pricing to terminate the age of hydrocarbons, we are adding increasing amounts of CO2 to the air, compounding the physical catastrophe currently happening across the globe.

The dilemma we face is simple: take real action to the scientific reality of our predicament or endure the consequences of this profound moral failure for centuries to come.
