According to Phys.org (emerging source), a study published in *Nature* by researcher Rosalie Arendt highlights systemic uncertainties in global net-zero climate plans. The article explains that vast amounts of carbon dioxide are being classified as "dealt with" in emissions accounting without verifiable evidence, a phenomenon Arendt terms "Schrödinger's carbon." This practice risks overestimating progress toward climate goals by assuming carbon removal technologies are effective before their outcomes are confirmed. The causal chain begins with the lack of rigorous verification in carbon accounting, which directly undermines the credibility of net-zero commitments. If unverified carbon removal claims are accepted as valid, policymakers may prioritize strategies reliant on unproven technologies, diverting resources from proven mitigation efforts. Short-term effects include eroded public trust in climate policies, while long-term impacts could delay meaningful emission reductions as stakeholders demand more transparent accountability mechanisms. This news event primarily affects the **environmental sustainability** domain, with secondary implications for **policy implementation** and **international cooperation**. The evidence type is a **research study** published in a peer-reviewed journal, lending moderate confidence to the findings. Uncertainties include whether current net-zero frameworks will adopt stricter verification protocols and how differing national standards might exacerbate inconsistencies in carbon accounting. The study’s conclusions depend on the assumption that unverified carbon removal claims are widespread, which may vary by region or sector.
