The answer is, gas and oil. Many countries buy oil and LNG from Russia, including the US and Canada. Time for Canada and the US to make these pipelines happen so we can both stop relying on Russian oil & gas and export these commodities to Europe. Effectively cutting off Russia. The most important issue now is not climate change, it's Russia. Build the pipelines and make Putin suffer. But I don't expect Trudeau to champion pipelines anytime soon, if ever. Canada has the capacity to be energy independent. Let's do it!
You don't need to build those pipelines first to make Putin suffer if you have
the will power.
Total oil + natural gas condensate production of Russia is roughly an
equivalent of 10 million barrels per day. Without any data handy I would
estimate the total amount exported to countries outside China the
biggest importer of Russian oil could not be much bigger than half of it.
Now 5 million barrels per day is huge but still only a fraction of the total
amount consumed by the world which falls in the range of an equivalent
of 80--100 million barrels of oil per day.. The western world can stop buying
oil from Russia altogether and per capita energy consumption should still
remain way higher than that of the developing world.
Stop buying oil from Russia starting tomorrow and Putin will be screwed.
Russia has an economy only about the size of Italy if I remember correctly.
