The GHG footprint, or greenhouse gas footprint, refers to the amount of GHG that are emitted during the creation of products or services. It is more comprehensive than the commonly used carbon footprint, which measures only carbon dioxide, one of many greenhouse gases. The GHG footprint differs from the ecological footprint in that the former is expressed in units of GHG warming potential (GGWP) and is generated by products or services, whereas the latter is expressed in units of land area and is generated by whole societies. == See also == * Ecological footprint * See also Resource flow and Resource stock in the Glossary Glossary of environmental science#R 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GHG footprint」の詳細全文を読む スポンサード リンク
