While world leaders gather in the Brazilian Amazon for Cop30, it is vital to evaluate how we are faring together in reducing global greenhouse gas emissions.

In spite of 30 years of UN climate summits, approximately half of the CO2 built up in the atmosphere since the Industrial Revolution has been emitted since 1990. Coincidentally, 1990 marked the publication of the initial scientific evaluation by the Intergovernmental Panel on Climate Change, which verified the danger of anthropogenic climate change. While researchers prepare the upcoming IPCC report, they do so aware that scientific findings remains overshadowed by political agendas. Despite well-intentioned efforts, the planet is still dangerously off track to prevent dangerous global warming.

Record-Breaking CO₂ Levels and Carbon-Based Fuel Dependency

Recent data show that CO₂ concentrations reached a record high of 423.9 parts per million in 2024, with the growth rate from the previous year surging by the largest yearly increase since record-keeping started in the late 1950s. Based on the international carbon monitoring initiative, 90% of worldwide carbon dioxide output in 2024 originated from burning fossil fuels, while the other tenth resulted from land-use changes such as forest clearance and forest fires.

Although the rise in carbon emissions from fuels in 2024 was propelled by higher use of gas and oil—representing over half of worldwide discharges—the use of coal also reached a historic peak, making up 41%. In spite of the previous climate summit's evaluation urging nations to transition away from fossil fuels, collective plans still aim to extract over twice the quantity of fossil fuels in the year 2030 than is consistent with limiting global warming to 1.5 degrees Celsius, with ongoing drilling of natural gas rationalized as a lower emission bridge fuel.

The Illusion of Eco-Friendly Measures

Rather than concentrating on economic incentives to accelerate the phase-out of carbon fuels, environmental strategies are overly dependent on feelgood eco-positive approaches that aim to neutralize CO2 output by planting trees rather than cutting industrial emissions. Although protecting, expanding, and rehabilitating natural carbon sinks like forests and marshes is inherently good, studies has demonstrated that there is insufficient territory to achieve the global goal of net zero emissions using ecological methods alone.

Roughly one billion hectares—an area larger than the USA—is required to fulfill carbon neutrality commitments. Over 40% of this land would need to be transformed from current applications like agriculture to carbon capture initiatives by 2060 at an never-before-seen pace.

Even if this ideal restoration could be realized, forests require years to grow and can burn down, so they cannot be considered as a quick or permanent CO2 retention method, particularly in a fast-changing climate. While severe temperatures and dryness engulf more of the planet, these well-intentioned efforts could actually be destroyed by fire.

The Diminishing of Planetary Absorbers

Scientific evidence indicates that about 50% of the carbon dioxide released annually remains in the atmosphere, while the remainder is taken up by oceans and land ecosystems. As the planet warms, these natural carbon sinks are becoming less effective at capturing CO₂, which means that additional CO2 builds up in the air, intensifying climate change. Shifting the mitigation burden onto the agricultural and forest sectors effectively excuses the fossil fuel industry from the pressure to cut pollution in the near future.

The Carbon Debt and Coming Populations

Achieving carbon neutrality by mid-century demands carbon dioxide removal (CDR), which currently depends largely on terrestrial methods to absorb excess carbon from the atmosphere. Polluters can easily purchase offsets to compensate for their emissions and proceed with normal operations. Meanwhile, the planetary heat imbalance resulting from the combustion of hydrocarbons keeps on further destabilise the Earth’s climate. Essentially, we are adding more carbon debt to our global account, leaving future generations with an unpayable liability.

To limit the scale and length of overshoot the global warming targets, the world eventually needs to surpass the balancing impact of net zero and begin to drawdown cumulative historical emissions to achieve net negative emissions.

The Policy Misrepresentation of Carbon Neutrality

According to the latest numbers from the Global Carbon Project, plant-based carbon removal is presently capturing the equal of about five percent of annual fossil carbon dioxide emissions, while technology-based CDR represents only about one-millionth of the CO2 emitted from fossil fuels. More generous sector projections suggest around 0.1% of total global emissions. Without meaning to be controversial, the policy twisting of net zero is an insidious loophole that takes focus away from the scientific imperative to eliminate the main source of our warming world—fossil fuels.

The Urgent Need for Concrete Action

While this research-backed truth should lead discussions at the climate summit, past events suggests that gradual, cautious steps and deference to politics will win out. Ambiguous promises of future ambition will continue to postpone the urgent need for definite short-term measures. Unless policymakers have the courage to put a price on carbon to terminate the age of hydrocarbons, we are releasing more and more carbon to the air, compounding the environmental disaster currently happening all around us.

The challenge we face is simple: genuinely respond to the scientific reality of our predicament or endure the consequences of this deep ethical lapse for generations ahead.
