emission coefficient vs emission coefficients

Both 'emission coefficient' and 'emission coefficients' are correct, but they are used in different contexts. 'Emission coefficient' is singular and refers to a single value or parameter, while 'emission coefficients' is plural and refers to multiple values or parameters.

This phrase is correct and commonly used in English.

"emission coefficient"

Use 'emission coefficient' when referring to a single value or parameter that quantifies the amount of emissions produced per unit of activity or substance.

Examples:

The emission coefficient of carbon dioxide is 2.3 kg per liter of fuel burned.
The emission coefficient for methane is higher than that of carbon dioxide.

These indicators should also be complemented by indicators of income inequality (Gini coefficient or inter-quintile ratio) and of CO2 emissions (per inhabitant or change since 1990).
the evolution coefficient of the emissions between zero and 'x' hours will be calculated for each pollutant:
