Tóm tắt

This analysis calculates the life cycle greenhouse gas (GHG) emissions from liquefied natural gas (LNG) exported from the U.S. and combusted by power plants in Europe or Asia and compares them to regional coal combusted by power plants in Europe and Asia. This analysis also calculates the GHG emissions from natural gas that is extracted in Russia and delivered by pipeline to European and Asian power plants. This analysis is based on data that were originally developed to represent U.S. energy systems: foreign natural gas and coal production were modeled as represented by U.S. natural gas production and average U.S. coal production. The results show that the use of U.S. LNG exports for power production in European and Asian markets will not increase GHG emissions, on a life cycle perspective, when compared to regional coal extraction and consumption for power production.
