While world leaders assemble in the Brazilian Amazon for Cop30, it is vital to evaluate how we are faring together in lowering worldwide emissions of greenhouse gases.
In spite of 30 years of United Nations climate conferences, nearly 50% of the carbon dioxide accumulated in the atmosphere after the dawn of industrialization has been released after the year 1990. Incidentally, 1990 was the publication of the First Assessment Report by the IPCC, which confirmed the threat of human-caused global warming. As scientists prepare the upcoming IPCC report, they do so aware that scientific findings remains overshadowed by political influences. Regardless of well-intentioned efforts, the planet is still dangerously off track to prevent catastrophic climate change.
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 jumping by the biggest annual rise since record-keeping started in 1957. According to the international carbon monitoring initiative, 90% of total global CO2 emissions in last year originated from the combustion of carbon-based energy sources, while the other tenth resulted from land-use changes such as deforestation and wildfires.
While the increase in fossil CO2 emissions in 2024 was propelled by increased use of gas and oil—accounting for over half of global emissions—coal burning also reached a historic peak, making up forty-one percent. In spite of Cop28’s global stocktake urging nations to move beyond fossil fuels, collective plans still intend to extract over twice the quantity of fossil fuels in the year 2030 than is consistent with keeping planet heating to 1.5 degrees Celsius, with continued extraction of gas rationalized as a lower emission bridge fuel.
Rather than focusing on financial motivators to speed up the phase-out of fossil fuels, climate policies are overly dependent on feel-good nature positive approaches that seek to cancel out CO2 output by planting trees instead of reducing factory discharges. While conserving, expanding, and rehabilitating ecological absorbers like forests and marshes is inherently good, studies has demonstrated that there is not enough land to reach the global goal of carbon neutrality using nature-based solutions by themselves.
Roughly 1 billion hectares—a territory larger than the USA—is needed to meet carbon neutrality commitments. Over 40% of this area would need to be transformed from existing uses like food production to carbon sequestration projects by 2060 at an never-before-seen pace.
Even if this ideal restoration could be realized, forests require years to grow and are susceptible to fires, so they should not be viewed as a fast or permanent carbon storage solution, especially in a fast-changing environment. While severe temperatures and aridity affect larger regions, these sincere attempts could actually go up in smoke.
Scientific evidence indicates that about half of the carbon dioxide released each year stays in the air, while the remainder is taken up by oceans and terrestrial systems. With global heating, these environmental absorbers are becoming less effective at capturing CO2, meaning that additional CO2 builds up in the atmosphere, intensifying global warming. Shifting the reduction responsibility onto the agricultural and forest sectors simply relieves the oil and gas sector from the pressure to cut pollution any time soon.
Reaching carbon neutrality by mid-century demands carbon dioxide removal (CDR), which currently relies almost exclusively on terrestrial methods to absorb excess carbon from the atmosphere. Polluters can simply buy carbon credits to counterbalance their emissions and continue with normal operations. Meanwhile, the planetary heat imbalance caused by the combustion of hydrocarbons keeps on further destabilise the Earth’s climate. In effect, we are increasing our climate liability to our planetary credit card, passing on future generations with an insurmountable burden.
To limit the scale and length of overshoot the Paris Agreement temperature goals, the planet ultimately needs to go well beyond the balancing impact of net zero and start to drawdown cumulative historical emissions to reach a carbon-negative state.
According to the most recent data from the international carbon research group, vegetation-based CDR is currently capturing the equivalent of about five percent of annual fossil carbon dioxide emissions, while engineered carbon extraction accounts for only about a tiny fraction of the CO2 emitted from carbon sources. Optimistic sector projections place it at around 0.1% of total global emissions. At the risk of sounding like a heretic, the policy twisting of net zero is a deceptive gap that takes focus away from the scientific imperative to eradicate the main source of our overheating planet—carbon-based energy.
While this research-backed truth should lead discussions at Cop30, past events indicates that gradual, cautious steps and political kowtowing will win out. Ambiguous promises of long-term goals will keep on delay the urgent need for definite short-term measures. Until policymakers are brave enough to implement carbon pricing to bring the era of fossil fuels to a definitive end, we are releasing increasing amounts of CO2 to the air, compounding the environmental disaster now unfolding all around us.
The dilemma we face is simple: genuinely respond to the scientific reality of our predicament or suffer the consequences of this deep ethical lapse for generations ahead.
