Acidification potential makes reference to different compounds that contribute to acid rain. These include sulfur dioxide (SO2), nitrogen oxides (NOx), nitrogen monoxide (NO), nitrogen dioxide (N2O), aswell as a variety of other substances.

Acidification potential is one of the core environmental impact indicators of EN 15804:2012+A2:2019/AC:2021which is used as guidance in the generation of the LCA methodology used to create Product Environmental Footprints (PEF). It is also considered as one of the mandatory environmental performance indicators for the calculation, assessment and generation of environmental product declarations (EPDs).

In the same way that the global warming potential (GWP) of different pollutants are converted to ratios CO2 equivalent figures (for example CO2 being 1:1 CO2 eq and Methane being 36.8 CO2 eq) Acidification potential is usually estimated in the same way but as a characterisation of SO2-equivalence. For example:

* 1 kg ammonia = 1.88 kg SO2 eq.
* 1 kg nitrogen dioxide = 0.7 kg SO2 eq.
* 1 kg sulphur dioxide = 1 kg SO2 eq.

Version 2.0 of the default list of indicators (valid from 2022-03-29)

AP, accumulated exceedence, EN 15804. Version: August 2021.

Original references 
Seppälä et al. 2006, Posch et al. 2008

Examples for unspecified emissions to air, unspecified location 
1 kg ammonia = 3.02 mol H+ eq. 
1 kg nitrogen oxides = 0.74 mol H+ eq. 
1 kg sulphur oxides = 1.31 mol H+ eq.

Version 1.0 of the default list of indicators (valid until 2022-12-31)

AP, CML 2001 non-baseline (fate not included). Version: January 2016.

Original reference 
Hauschild & Wenzel (1998)

Examples 
1 kg ammonia = 1.88 kg SO2 eq. 
1 kg nitrogen dioxide = 0.7 kg SO2 eq. 
1 kg sulphur dioxide = 1 kg SO2 eq.

Please notice the use of non-baseline characterization factors for acidification potential.
