GWP
GWP — Global Warming Potential
kg CO₂-eq, the contribution of greenhouse gases to climate change. EN 15804+A2 reports GWP-total, fossil, biogenic, luluc separately.
Impact Categories
LCA impact categories and EN 15804+A2 alignment
Core and additional impact categories reported in the EN 15804+A2 modulary table. Definition, unit and EN 15804+A2 alignment for each.
ODP
ODP — Ozone Depletion Potential
kg CFC-11-eq, the impact of halocarbons damaging the stratospheric ozone layer.
AP
AP — Acidification Potential
mol H+-eq, contribution of SO₂, NOx and NH₃ emissions causing acid rain to terrestrial acidification.
EP
EP — Eutrophication Potential
In EN 15804+A2 split into three: freshwater (kg P-eq), marine (kg N-eq) and terrestrial (mol N-eq).
POCP
POCP — Photochemical Oxidation
kg NMVOC-eq, contribution to tropospheric ozone and smog formation.
ADP
ADP — Abiotic Resource Depletion
Two sub-indicators: kg Sb-eq (minerals & metals) and MJ (fossil fuels).
CED
CED — Cumulative Energy Demand
MJ of total primary energy demand over the life cycle (renewable + non-renewable).
