GNL Quebec is a megaproject comprising a 782 km pipeline (the Gazoduq Project), a liquefied natural gas plant (the Énergie Saguenay Project) and a marine terminal where supertankers would be loaded with liquefied natural gas (LNG) to transport it to foreign markets via the Saguenay Fjord and the St. Lawrence River. Those supporting this project assert it would contribute to the fight against global warming because hydropower would be used to liquefy the gas and because the exported gas would replace coal and oil " in Europe, Asia and elsewhere ."

In this era of climate change and biodiversity collapse, we believe that scientists have a duty to take a stand on major projects that would affect the future of our civilization. It is in this spirit that we are taking part today in the public debate on the GNL Quebec project.

In fact, this project would not help fight climate change. It would facilitate the daily extraction, in the Canadian Prairies, of 44 million cubic meters of natural gas, which amounts to 2.6 times the total daily consumption of Quebec. Canada, which is already the world's fifth largest natural gas exporter, would see its net natural gas exports jump by 27 per cent if this project went forward.

According to an industry-commissioned life cycle assessment of this gas, from its extraction to the exit point of the liquefaction plant, it would produce more than 7.8 million tonnes of greenhouse gas (GHG) per year. This means that the total emissions associated with this project within Canada would be comparable to the sum total of GHG emission reductions in Quebec since 1990. A key uncertainty in these calculations is the amount of fugitive gas emissions (leaks) occurring during its extraction, throughout the whole transport chain and after wells are abandoned. Considering that natural gas is mainly methane, a greenhouse gas 84 times more potent than CO2 over a 20-year period, the global warming effect of these leaks is enormous, and there is therefore potential for total GHG emissions associated with this project to be considerably higher than the best available estimate. Moreover, GNL Quebec carefully avoids highlighting the large amounts of downstream CO2 emissions resulting from the combustion of the gas. According to our calculations, these emissions would add roughly 30 million tonnes of CO2 per year, assuming no fugitive gas emissions. That number spikes dramatically when applying average fugitive emissions under normal operating conditions.

Moreover, GNL Quebec would have no control over the end use of this gas, and there is no evidence that its use would replace coal or oil fuel. It is just as likely that this gas could replace renewable energy sources, which would only increase the world’s continued reliance on fossil fuels, and slow the desperately needed development of alternative energy technologies.

Let us remember that in order to limit global warming to 1.5 C, we must reduce GHG emissions by about 45 per cent by 2030, as compared to 2010, and achieve carbon neutrality by 2050. To achieve this, it is essential that we wind down the number of fossil fuel infrastructures, not build more of them.



The GNL Quebec project also poses a serious threat to biodiversity. By cutting right across the natural environment of Northern Quebec, from Abitibi- Témiscamingue to the Saguenay Fjord, the Gazoduq pipeline would fragment the habitat of 17 vulnerable, threatened or endangered species. It would go through the catchment areas of the Harricana, Nottaway, Moose, Outaouais, Saint-Maurice and Saguenay rivers. Finally, exporting this liquefied gas would require six to eight mega-tanker transits per week in the fjord. The deafening underwater noise from these giant ships would jeopardize the survival of the St. Lawrence beluga in the only acoustic refuge it still has.

Taken as a whole, this project would thus further alter the terrestrial and marine ecosystems on which life on Earth depends, even as UN-mandated experts have recently confirmed an "unprecedented" and accelerating rate of extinction of species, thus eroding "the very foundations of our economies, our livelihoods, food security, health and quality of life around the world."
