Natural gas liquefied (natural gas liquefied import from US)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product 'natural gas liquefied' is a fossil fuel for which a generic gross calorific value (GCV) of 40MJ/m3 a net calorific value (NCV) of 36.0 MJ/m3 and a density of 0.735kg/m3 are applied in line with the global statistics (referring to standard cubic meters Sm3 measured at 15°C and 1013 mbar). That is the reference flow refers to 1 standard cubic meter of natural gas in the gaseous state. At a density of 410-500 kg/m3 the volume of liquified natural gas is around 1/600th of the gaseous volume at standard conditions. Natural gas is liquefied for transportation and/or storage and it is sourced from natural gas liquefaction plants. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
