Ozone depletion potential
Ozone Depletion Potential (ODP) refers to the relative amount of degradation a chemical compound can cause to the ozone layer. It is similar to Global Warming Potential (GWP) though this a measure of how much a given mass of a gas contributes to global warming.
ODP is an environmental impact indicator of EN 15804:2012+A2:2019/AC:2021 which is used as guidance in the generation of the life cycle assessment (LCA) methodology used to create Product Environmental Footprints (PEF). It is also one of the environmental performance indicators for the calculation, assessment and generation of environmental product declarations (EPDs).
ODP as a measure of how much damage a chemical can cause to the ozone layer is compared with a similar mass of trichlorofluoromethane (CFC-11) as a ratio. CFC-11, with an ozone depleting potential of 1.0, is used as the base figure for measuring ozone depleting potential.
