What does decarbonising mean?
Decarbonising means reducing or eliminating the carbon emissions associated with human activity, particularly the burning of coal, oil, and gas. The word is used in discussions of energy, transport, buildings, industry, and the wider economy, as in decarbonising the electricity sector or decarbonising industry. It can also mean lowering the amount of carbon in a material or process. In public debate, decarbonising carries a strongly constructive connotation: it describes a planned transition toward cleaner technologies and energy sources rather than merely compensating for emissions after they occur. The term became especially prominent in international climate policy, business strategy, and technology as governments and organizations set targets for reducing emissions. Although decarbonising is closely associated with the present participle decarbonise, the related noun decarbonisation is also widely used. The expression is formal and technical, and its British spelling is decarbonising, while US English commonly uses decarbonizing.
verb (present participle/gerund)Reducing or eliminating carbon emissions, especially those produced by the use of fossil fuels in energy, transport, and industry. It can also refer more generally to lowering the carbon content of a substance, process, or system.
- To reduce or eliminate carbon emissions from energy, transport, industry, or other human activity.

"The government is introducing subsidies to help businesses decarbonise their manufacturing processes."
"Her research focuses on decarbonising steel production through the use of hydrogen-based fuels."
Decarbonising treats carbon as something to phase out at the source, not merely clean up after it has been emitted.

Where does decarbonising come from?
The word combines the English prefix de-, meaning removal or reversal, with carbon and the verbal suffix -ise, giving it the sense of taking carbon away. Carbon itself comes through French from the Latin carbo, meaning coal or charcoal, and the same Latin root underlies words such as carbonate, carbonic, and carbohydrate. English developed both decarbonise and decarbonization, with the spelling decarbonising characteristic of British usage and decarbonizing characteristic of American usage.
