While world leaders assemble in the Brazilian Amazon for Cop30, it is crucial to assess our collective progress in lowering global greenhouse gas emissions.

In spite of three decades of United Nations climate conferences, approximately half of the CO2 built up in the atmosphere after the dawn of industrialization has been emitted after the year 1990. Coincidentally, 1990 marked the publication 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 scientific findings remains eclipsed by political agendas. Despite sincere attempts, the world is remains dangerously off track to prevent dangerous global warming.

Unprecedented CO₂ Levels and Carbon-Based Fuel Dependency

Latest figures show that atmospheric carbon dioxide levels hit a record high of 423.9 parts per million in the year 2024, with the growth rate from 2023 to 2024 surging by the largest yearly increase since modern measurements began in the late 1950s. According to the Global Carbon Project, 90% of worldwide carbon dioxide output in 2024 originated from the combustion of carbon-based energy sources, while the other tenth resulted from land-use changes such as deforestation and forest fires.

Although the increase in fossil CO₂ emissions in 2024 was propelled by higher use of natural gas and petroleum—representing more than 50% of worldwide discharges—the use of coal also reached a historic peak, making up 41%. In spite of Cop28’s global stocktake calling for nations to move beyond fossil fuels, collective plans still aim to extract over twice the quantity of hydrocarbons in 2030 than is consistent with keeping global warming to 1.5C, with ongoing drilling of natural gas justified as a less polluting transition fuel.

The Illusion of Nature-Based Solutions

Instead of focusing on economic incentives to speed up the elimination of carbon fuels, climate policies are heavily reliant on feelgood nature positive approaches that aim to cancel out CO2 output by afforestation rather than cutting factory discharges. While protecting, enlarging, and restoring ecological absorbers like woodlands and wetlands is inherently good, research has shown that there is insufficient territory to achieve the worldwide target of carbon neutrality using nature-based solutions alone.

Approximately 1 billion hectares—an area larger than the United States of America—is needed to meet net zero pledges. More than forty percent of this area would need to be transformed from current applications like agriculture to carbon capture initiatives by 2060 at an unprecedented rate.

Although this ideal restoration could be achieved, woodlands require years to grow and can burn down, so they should not be viewed as a fast or lasting carbon storage solution, particularly in a fast-changing environment. As severe temperatures and aridity affect larger regions, these well-intentioned efforts could actually be destroyed by fire.

The Weakening of Natural Carbon Sinks

Scientific evidence tells us that about 50% of the carbon dioxide released annually stays in the air, while the rest is absorbed by oceans and land ecosystems. With global heating, these natural carbon sinks are losing efficiency at capturing CO₂, meaning that more carbon builds up in the air, further exacerbating climate change. Shifting the reduction responsibility onto the agricultural and forest sectors effectively excuses the fossil fuel industry from the pressure to reduce emissions in the near future.

The Climate Liability and Coming Populations

Reaching net zero by 2050 requires CO2 extraction (CDR), which at present relies almost exclusively on terrestrial methods to soak up surplus CO2 from the air. Polluters can simply buy carbon credits to counterbalance their discharges and continue with business as usual. Meanwhile, the planetary heat imbalance resulting from the burning of fossil fuels keeps on further destabilise the Earth’s climate. Essentially, we are adding more carbon debt to our global account, passing on future generations with an unpayable liability.

To limit the scale and duration of exceeding the global warming targets, the planet ultimately needs to surpass the neutralising effect of carbon neutrality and start to drawdown past carbon outputs to reach a carbon-negative state.

The Policy Misrepresentation of Net Zero

According to the most recent data from the international carbon research group, plant-based carbon removal is currently capturing the equal of about 5% of annual fossil carbon dioxide emissions, while technology-based CDR represents only about a tiny fraction of the carbon released from carbon sources. Optimistic sector projections suggest around zero point one percent of worldwide CO2 output. Without meaning to be controversial, the policy twisting of carbon neutrality is a deceptive gap that distracts from the research-based necessity to eliminate the primary cause of our warming world—carbon-based energy.

The Critical Requirement for Concrete Action

Although this research-backed truth should dominate discussions at Cop30, history indicates that polite incrementalism and political kowtowing will prevail. Vague statements of long-term goals will continue to delay the pressing requirement for concrete immediate action. Unless leaders are brave enough to put a price on carbon to terminate the age of hydrocarbons, we are adding more and more carbon to the atmosphere, worsening the physical catastrophe now unfolding across the globe.

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