While world leaders assemble in the Brazilian Amazon for Cop30, it is vital to review how we are faring together in reducing worldwide emissions of greenhouse gases.

Despite 30 years of United Nations climate conferences, nearly 50% of the CO2 built up in the atmosphere since the Industrial Revolution has been released after the year 1990. Incidentally, 1990 marked the release of the First Assessment Report by the Intergovernmental Panel on Climate Change, which confirmed the threat of anthropogenic climate change. While researchers work on the upcoming IPCC report, they do so aware that their work remains overshadowed by political agendas. Despite sincere attempts, the planet is still dangerously off track to avert catastrophic climate change.

Unprecedented CO₂ Levels and Carbon-Based Fuel Dependency

Recent data indicate that atmospheric carbon dioxide levels hit a new peak of 423.9 parts per million in the year 2024, with the increase rate from the previous year jumping by the largest yearly increase since record-keeping started in the late 1950s. According to the international carbon monitoring initiative, ninety percent of worldwide carbon dioxide output in last year came from the combustion of carbon-based energy sources, while the remaining 10% resulted from alterations in land use such as forest clearance and wildfires.

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—coal burning also reached a record high, making up 41%. In spite of Cop28’s global stocktake calling for nations to transition away from carbon fuels, collective plans still aim to extract over twice the quantity of fossil fuels in 2030 than is consistent with keeping planet heating to 1.5 degrees Celsius, with ongoing drilling of natural gas rationalized as a lower emission transition fuel.

The Mirage of Nature-Based Solutions

Rather than focusing on financial motivators to speed up the elimination of fossil fuels, environmental strategies are overly dependent on feel-good eco-positive approaches that aim to neutralize carbon emissions by afforestation instead of reducing factory discharges. While conserving, enlarging, and restoring natural carbon sinks like forests and marshes is inherently good, research has shown that there is insufficient territory to achieve the global goal of carbon neutrality using nature-based solutions by themselves.

Roughly 1 billion hectares—an area larger than the USA—is required to fulfill net zero pledges. Over forty percent of this land would need to be converted from current applications like agriculture to carbon capture initiatives by 2060 at an never-before-seen pace.

Although this regenerative utopia could be realized, forests require years to grow and can burn down, so they cannot be considered as a quick or lasting CO2 retention method, particularly in a rapidly shifting environment. As extreme heat and dryness affect larger regions, these sincere attempts could literally be destroyed by fire.

The Weakening of Natural Carbon Sinks

Research data indicates that about 50% of the total CO₂ emitted each year remains in the atmosphere, while the rest 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 accumulates in the atmosphere, further exacerbating global warming. Transferring the mitigation burden onto the land sector effectively excuses the oil and gas sector from the urgency to cut pollution any time soon.

The Carbon Debt and Future Generations

Achieving net zero by 2050 requires CO2 extraction (CDR), which at present depends largely on land-based measures to absorb excess carbon from the atmosphere. Emitting companies can simply buy carbon credits to compensate for their discharges and proceed with normal operations. At the same time, the planetary heat imbalance resulting from the combustion of hydrocarbons keeps on further destabilise the Earth’s climate. Essentially, we are increasing our climate liability to our global account, passing on our descendants with an insurmountable burden.

To limit the scale and duration of exceeding the Paris Agreement temperature goals, the planet eventually needs to go well beyond the balancing impact of carbon neutrality and start 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 presently absorbing the equivalent of about five percent 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 industry estimates place it at around 0.1% of worldwide CO2 output. At the risk of sounding like a heretic, the policy twisting of net zero is an insidious loophole that takes focus away from the scientific imperative to eradicate the main source of our overheating planet—fossil fuels.

The Critical Requirement for Concrete Action

While this research-backed truth should lead discussions at the climate summit, past events indicates that polite incrementalism and deference to politics will win out. Vague statements of future ambition will keep on delay the pressing requirement for concrete immediate action. Until policymakers have the courage to implement carbon pricing to terminate the age of hydrocarbons, we are adding increasing amounts of CO2 to the atmosphere, compounding the physical catastrophe now unfolding all around us.

The dilemma we face is straightforward: genuinely respond to the evidence-based situation of our crisis or endure the results of this profound moral failure for centuries to come.
