The time for piplelines is past.
The Government of Canada has declared a climate emergency. Every step should be taken to address that emergency — greenhouse gas emissions must be stopped, and all activities that lead to furthering the climate emergency must be halted. This includes stopping building of pipelines, for which the sole purpose is to transport fossil fuels that will be burned to create more greenhouse gases.
There are other issues which have been raised that make this particular pipeline troublesome: the funding of electricity to power the liquifaction of the gas (the costs of purchasing electricity from Quebec will be subsidized by the taxpayer, so that Gazoduq will actually receive more money to purchase that electricity than the electricity costs); that the destination for the LNG product is other countries, placing the blame on them for the actual burning of GHG emitting fossil fuels; that the entire operation of transport and liquifaction of gas will result in GHG emissions; and that the extraction of the gas is one of the dirtiest industries in the world, resulting in irreversible damage to the Canadian landscape where it is extracted.
But all that pales to the foremost issue: A pipeline is designed for a purpose that will result in worsening the climate emergency, not bettering it. For that reason alone this pipeline project must not be allowed.
