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

Despite three decades of UN climate summits, approximately half of the carbon dioxide accumulated in the atmosphere after the dawn of industrialization has been released since 1990. Incidentally, 1990 was the release 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 influences. Despite well-intentioned efforts, the planet is still far from the path to prevent catastrophic climate change.

Record-Breaking CO₂ Levels and Carbon-Based Fuel Dependency

Recent data indicate that atmospheric carbon dioxide levels hit a record high of 423.9 ppm in 2024, with the growth rate from 2023 to 2024 jumping by the biggest annual rise since modern measurements began in 1957. Based on the Global Carbon Project, ninety percent of total global CO₂ emissions in last year came from burning fossil fuels, while the remaining 10% was due to land-use changes such as forest clearance and wildfires.

While the increase in fossil CO₂ emissions in 2024 was propelled by increased use of natural gas and petroleum—representing over half of worldwide discharges—coal burning also attained a historic peak, making up 41%. In spite of Cop28’s global stocktake urging nations to transition away from fossil fuels, global strategies still aim to produce more than double the amount of hydrocarbons in 2030 than aligns with keeping global warming to 1.5 degrees Celsius, with ongoing drilling of gas justified as a less polluting transition fuel.

The Mirage of Nature-Based Solutions

Instead of focusing on financial motivators to speed up the elimination of carbon fuels, environmental strategies are heavily reliant on feel-good eco-positive approaches that aim to neutralize carbon emissions by planting trees rather than cutting industrial emissions. Although protecting, expanding, and restoring ecological absorbers like forests and wetlands is inherently good, research has demonstrated that there is not enough land to reach the worldwide target of net zero emissions using ecological methods alone.

Approximately one billion hectares—a territory larger than the USA—is required to meet net zero pledges. Over 40% of this land would need to be converted from existing uses like agriculture to carbon sequestration projects by the year 2060 at an unprecedented rate.

Although this ideal restoration could be realized, woodlands take time to mature and can burn down, so they should not be viewed as a fast or lasting carbon storage solution, particularly in a rapidly shifting climate. While extreme heat and aridity affect larger regions, these sincere attempts could literally go up in smoke.

The Diminishing of Natural Carbon Sinks

Research data tells us that about 50% of the total CO₂ emitted annually remains in the atmosphere, while the rest is taken up by seas and land ecosystems. With global heating, these natural carbon sinks are becoming less effective at soaking up CO₂, meaning that more carbon accumulates in the air, further exacerbating climate change. Shifting the mitigation burden onto the land sector effectively excuses the oil and gas sector from the urgency to cut pollution in the near future.

The Carbon Debt and Coming Populations

Reaching net zero by 2050 requires carbon dioxide removal (CDR), which currently relies almost exclusively on terrestrial methods to soak up surplus CO2 from the air. Emitting companies can simply purchase offsets to compensate for their emissions and proceed with normal operations. At the same time, the planetary heat imbalance caused by the burning of fossil fuels keeps on further destabilise the Earth’s climate. In effect, we are adding more carbon debt to our global account, passing on our descendants with an insurmountable burden.

To curb the magnitude and duration of exceeding the global warming targets, the planet eventually needs to go well beyond the balancing impact of carbon neutrality and start to drawdown past carbon outputs to reach a carbon-negative state.

The Policy Misrepresentation of Carbon Neutrality

According to the most recent data from the Global Carbon Project, plant-based carbon removal is currently capturing the equivalent of about five percent of annual fossil carbon dioxide emissions, while technology-based CDR accounts for only about one-millionth of the CO2 emitted from carbon sources. More generous industry estimates suggest around zero point one percent of worldwide CO2 output. Without meaning to be controversial, the political distortion of carbon neutrality is an insidious loophole that takes focus away from the research-based necessity to eliminate the primary cause of our overheating planet—carbon-based energy.

The Urgent Need for Concrete Action

While this research-backed truth should dominate talks at Cop30, past events suggests that polite incrementalism and political kowtowing will prevail. Vague statements of future ambition will keep on delay the pressing requirement for concrete immediate action. Until policymakers are brave enough to implement carbon pricing to terminate the age of hydrocarbons, we are releasing more and more carbon to the atmosphere, compounding the physical catastrophe now unfolding all around us.

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