The map below is of CO₂ emissions (from Our World in Data). It labels countries as being either "Below global equity" or "Above global equity".

enter image description here

Here the word "equity" seems to have been used to mean "(world) average". Is such usage correct/common/acceptable?

  • the authors opinioned definition of equity is in the article you cite: 'Countries in red have per capita emissions above global 'equity' (meaning they emit more than their population share); those in blue are below the global average.'

Here, equity is treated as allowed fair level of CO2 to be emitted (by any country).

"Above global equity" = Above fair level

"Below global equity" = Below fair level

Global Carbon Project (G.C.P) or any respective international organization might have agreed upon on some fair level of CO2 emission i.e. allowed level of CO2 emission.

So, the countries in the red are emitting CO2 than above fair level. Whereas, the countries in the blue are emitting CO2 than below fair level.

Equity according to Oxford Dictionary is

Meaning (Entry 1): The quality of being fair and impartial.

Usage: The focus here has rarely been on equity or on a fair deal for the poor
