The quality of being intense; in environmental terms, the amount of emissions per unit of output (like GDP or energy).

Carbon intensity is a measure of efficiency. You can have high total emissions but low intensity if you produce a lot of value for every gram of carbon.

The story behind the word. From 'in-' (into) and 'tendere' (to stretch). It originally described the 'stretching' of a string or a feeling. In physics and economics, it evolved to describe the 'concentration' of force or emissions.

Word relationships

  • concentration: Concentration refers to the amount of a substance in a space; intensity refers to the rate of emissions relative to production.
  • dilution: Dilution is the process of making something weaker or less concentrated.

Commonly confused with

  • magnitude: Magnitude refers to the size or extent of something; intensity refers to its strength or efficiency ratio.

Word family

  • intense (adjective): Of extreme force or degree.
  • intensify (verb): To make more intense.

Collocations

  • carbon intensity
  • energy intensity
  • emission intensity

Example sentences

  • "Reducing the carbon intensity of energy is crucial for meeting climate targets while maintaining economic growth." Energy efficiency metrics.

Memory hook

Think of an 'Intense' workout—you are doing a lot of work in a small amount of time. Carbon intensity is how much 'work' (carbon) is in a unit of 'output'. Carbon per unit.

When not to use

Don't use it as a synonym for 'volume.' Intensity is a ratio, not a total amount.

Fun facts

  • The carbon intensity of the global economy has been falling for decades, even as total emissions have risen.
