Scientists have warned that countries may exploit natural carbon sinks, such as forests and oceans, to falsely claim they’ve achieved net zero emissions while continuing to contribute to Global warming. This comes from a recent study published in Nature, led by the University of Oxford, which states that these natural absorbers, vital in mitigating historic Pollution, should not be accounted for in meeting the current net zero targets originally defined in 2009.

Annually, Earth’s natural ecosystems absorb approximately half of all human carbon emissions, playing a crucial role under the Paris Agreement to keep global heating below 2 degrees Celsius. However, the researchers behind the net zero concept have expressed concerns that these natural processes are being counted towards the Paris targets, allowing countries to appear as though they have neutralized their carbon footprint without actually reducing fossil fuel emissions.
The term “geological net zero” was emphasized in the study, suggesting that any new emissions must be offset by permanent removal methods, not just through existing ecosystems. The upcoming COP29 in Azerbaijan was highlighted as a critical moment for governments to redefine what achieving net zero truly means, to avoid catastrophic climate outcomes.
The study also sheds light on the discrepancies in how carbon removals are calculated within national contributions to the Paris Agreement. Managed lands, like sections of the Amazon and Russian taiga, are included in national targets, whereas emissions from unmanaged lands, such as recent wildfires in Canada, are excluded. This selective accounting leads to significant gaps in true carbon budgets, potentially overstating progress towards climate goals.
Prof. Myles Allen from Oxford, and Dr. Glen Peters from the Cicero Center for International Climate Research, cautioned against the misuse of natural carbon removal credits, particularly those from uncontrolled, naturally occurring events. They stressed the necessity for immediate, substantive changes to industrial practices over reliance on carbon sinks.
This critical analysis from Zero Carbon Analytics reveals that nature’s role in national climate plans is a glaring oversight, calling for a more realistic and rigorous approach to environmental accounting and a reevaluation of land use classifications in climate commitments.
