Global GHG emissions by sector & atmospheric CO₂ — 2013 to 2023
Tier A sectors (reliable IEA/EDGAR/FAO data) · Unit: GtCO₂e/yr
Red curve = atmospheric CO₂ concentration (ppm, right axis) · Source: NOAA Mauna Loa
Key message: even where annual emissions plateau, the atmospheric stock keeps growing relentlessly
