Global environmental impacts
Global warming potential, GWP (CO2 equivalents), is a product's potential contribution to global warming in the course of its lifetime. Global warming potential is the measure of how much a given mass of greenhouse gases (e.g. CO2 and CH4) contributes to global warming. The potential of any greenhouse gas is converted to the CO2 equivalent.
The depletion potential of the stratospheric ozone layer, ODP (kg CFC 11 equivalents), is a product's potential contribution to the breakdown of the ozone layer.
Regional environmental impacts
Acidification for soil and water
Discharge of sulphur and nitrogen
causes a high degree of acidity, which induces the death of fish (acid lakes) and forest decline (acid rain). Acidification potential, AP (kg SO2 equivalents), is a product's potential to release sulphur- and nitrogen dioxides in its combustion.
Discharge of the nutrients nitrogen and phosphorus from agriculture and combustion processes leads to eutrophication in lakes and seas – also known as
algal blooms. The eutrophication
potential, EP (kg PO4)3- equivalents,
is a product's potential to cause
eutrophication during its lifetime.
