RICHMOND, B.C. -- Federal cabinet has conditionally approved the $36-billion Pacific NorthWest liquefied natural gas project. Here are five things to know about the proposed project:

The Players:

Petronas, the Malaysian state-owned oil and gas giant, is leading the development. It has a 62 per cent stake in both the LNG processing facility on Lelu Island and the natural gas reserves in northeastern B.C. that would feed into it. Other partners include Sinopec with a 15 per cent stake, JAPEX and the Indian Oil Corp. with 10 per cent each, and PetroleumBRUNEI with three per cent.

The Product:

LNG is produced by cooling natural gas (consisting mostly of methane) to minus 162 degrees Celsius in order to make it a liquid. LNG takes up 1/600th of the space that it takes up in its gaseous state. The export facility would take in up to 3.2 billion cubic feet of natural gas per day and produce up to 19.2 million tonnes of LNG a year.

The Environmental Impact:

The draft environmental report released in February estimated that the LNG facility would result in the equivalent of 5.3 million tonnes of carbon dioxide being released a year. That would add 8.5 per cent to B.C.'s total emissions. Upstream emissions, including the gathering of the natural gas, are estimated to add the equivalent of 6.5 million to 8.7 million more tonnes of CO2.

State of the Industry:

A glut of global LNG projects have led to a drop in prices and prospects for LNG as well. The Shell-led LNG Canada project, which would have been built near Kitimat, B.C., was indefinitely delayed in July. AltaGas Ltd. also shelved its smaller Douglas Channel LNG project in February.

The Costs:

The entire Pacific NorthWest LNG project is estimated to cost $36 billion. That includes about $11 billion for the export terminal, $6.5 billion in pipelines, the $5.5 billion Petronas spent buying Progress Energy, and the roughly $2 billion a year the consortium would spend on drilling and production of natural gas to get the project fully operational.
