While world leaders convene in the Brazilian Amazon for Cop30, it is vital to assess our collective progress in lowering worldwide emissions of greenhouse gases.

In spite of 30 years of UN climate summits, nearly 50% of the CO2 built up in the atmosphere since the Industrial Revolution has been emitted 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 human-caused global warming. While researchers prepare the Seventh Assessment Report, they do so knowing that scientific findings remains overshadowed by political agendas. Despite sincere attempts, the world is still far from the path to avert dangerous global warming.

Unprecedented CO₂ Levels and Carbon-Based Fuel Dependency

Latest figures indicate that CO₂ concentrations reached a record high of 423.9 ppm in 2024, with the growth rate from 2023 to 2024 jumping by the largest yearly increase since record-keeping started in 1957. Based on the Global Carbon Project, 90% of worldwide carbon dioxide output in last year came from burning fossil fuels, while the remaining 10% was due to alterations in land use such as deforestation and forest fires.

Although the increase in carbon emissions from fuels in recent times was driven by increased use of natural gas and petroleum—representing more than 50% of global emissions—coal burning also reached a record high, constituting 41%. Despite the previous climate summit's evaluation urging nations to move beyond carbon fuels, collective plans still intend to extract over twice the amount of fossil fuels in 2030 than aligns with keeping global warming to 1.5C, with ongoing drilling of natural gas justified as a lower emission transition fuel.

The Mirage of Eco-Friendly Measures

Rather than concentrating on economic incentives to speed up the phase-out of fossil fuels, climate policies are heavily reliant on feel-good nature positive approaches that aim to neutralize carbon emissions by afforestation rather than cutting factory discharges. While protecting, expanding, and rehabilitating natural carbon sinks like forests and wetlands is inherently good, research has demonstrated that there is insufficient territory to achieve the worldwide target of net zero emissions using nature-based solutions alone.

Approximately one billion hectares—an area larger than the United States of America—is needed to meet net zero pledges. More than forty percent of this land would need to be converted from current applications like food production to carbon sequestration projects by the year 2060 at an never-before-seen pace.

Although this ideal restoration could be achieved, forests require years to grow and are susceptible to fires, so they should not be viewed as a quick or lasting CO2 retention method, especially in a fast-changing environment. While severe temperatures and aridity affect more of the planet, these sincere attempts could actually go up in smoke.

The Diminishing of Planetary Absorbers

Research data tells us that about 50% of the carbon dioxide released annually stays in the air, while the rest is taken up by oceans and terrestrial systems. As the planet warms, these natural carbon sinks are losing efficiency at capturing CO₂, which means that more carbon builds up in the air, intensifying climate change. Shifting the mitigation burden onto the agricultural and forest sectors simply relieves the oil and gas sector from the urgency to cut pollution in the near future.

The Climate Liability and Future Generations

Reaching carbon neutrality by mid-century demands carbon dioxide removal (CDR), which at present depends largely on land-based measures to soak up surplus CO2 from the atmosphere. Polluters can easily purchase offsets to compensate for their discharges and continue with normal operations. At the same time, the planetary heat imbalance resulting from the burning of fossil fuels continues to further disrupt the Earth’s climate. Essentially, we are increasing our climate liability to our planetary credit card, leaving future generations with an insurmountable burden.

To curb the scale and duration of exceeding the global warming targets, the world ultimately needs to go well beyond the balancing impact of net zero and begin to drawdown past carbon outputs to reach a carbon-negative state.

The Policy Misrepresentation of Carbon Neutrality

According to the latest numbers from the international carbon research group, vegetation-based CDR is presently capturing the equal of about five percent of yearly CO2 from fuels, while technology-based CDR represents only about one-millionth of the CO2 emitted from carbon sources. Optimistic industry estimates place it at around zero point one percent of total global emissions. Without meaning to be controversial, the policy twisting of net zero is a deceptive gap that takes focus away from the scientific imperative to eliminate the primary cause of our warming world—carbon-based energy.

The Critical Requirement for Definite Steps

While this scientific reality should dominate talks at the climate summit, history suggests that polite incrementalism and political kowtowing will prevail. Vague statements of future ambition will continue to postpone the pressing requirement for concrete immediate action. Until policymakers are brave enough to put a price on carbon to terminate the age of hydrocarbons, we are releasing increasing amounts of CO2 to the atmosphere, worsening the environmental disaster currently happening all around us.

The dilemma we face is straightforward: genuinely respond to the scientific reality of our crisis or endure the consequences of this deep ethical lapse for centuries to come.
