AI Summary

A new report indicates that global carbon emissions may start declining this year, marking a potential first downward trend. Analysts caution the finding could be a temporary dip linked to the U.S.–Iran war, so confirmation will require several years of data. Emissions arise from the combustion of coal, gas and oil in power plants, factories, vehicles and heating systems worldwide. Researchers note that roughly half of all CO₂ released since the industrial era has been emitted since 1990, underscoring the urgency of reaching net‑zero by mid‑century.
