🔡 Root

Latin de- = removal/reversal + carbo = coal, charcoal + -isation = process of making

📜 Etymology

From English de- ("removal") + carbon (from Latin carbo, "coal, charcoal") + -isation (suffix denoting a process); earliest known use in the 1830s, originally referring to removal of carbon from metals, with the climate-policy sense emerging in the late 20th century.

🧠 Memory Hook

De- (remove) + carbon — literally "de-carbon-ising" the economy: take the carbon OUT of how we make energy.
