Eco-Indicator 99’	As a lifecycle impact assessment tool developed by Consultants B.V., designers can perform environmental assessments of products by calculating environmental mark scores for used materials and processes.
ISO 14000 series	Environmental management life cycle assessment principles and framework, Korean Agency for Technology and Standard, 2007.
Global warming potential (GWP)	In a relative sense, it is a type of index based on a simplified radiative characteristic that can be used to measure the possible future impacts of the evolution of various gases on the climate system in the future.
ODP (ozone layer depletion potential)	It is a numerical expression of the degree of destruction of compounds that destroy ozone. Based on the ozone depletion capacity of CFC-11 as 1, the destructive power of the remaining chemicals was assumed.
AP (acidification potential)	Acidification occurs primarily when nitrogen oxides (NOx) and sulfur dioxide gas (SO2) interact with other atmospheric components.
EP (eutrophication potential)	It refers to a phenomenon in which nutrients are excessively supplied to water due to the inflow of chemical fertilizers or sewage, causing rapid growth or extinction of plants and killing organisms by taking away oxygen from the water.
ETP (ecotoxicity potential)	Ecotoxicity refers to the ecological impacts of chemicals, pesticides, and pharmaceuticals on freshwater organisms and the possible risks to the aquatic ecosystem.
Human toxicity potential (HTP)	Total emissions are assessed in terms of benzene and toluene equivalents, but potential doses include multiple routes of exposure, including inhalation, ingestion, and dermal contact of fish and meat.
