   @peterbrown @straphanger so, I am in favour of Alto.

   But.

   The reduction in greenhouse gas emissions from Alto are not projected to be high, about 1Mt/year -- that's about 0.1% of Canada's total annual emissions around 700Mt.

   And the high cost of the project, about $60-90B, makes it a very expensive way to reduce a modest amount of emissions.

   So, one reason I've heard people oppose the project is that the money could have a lot more impact if it was used in other ways.

   The bottom line is this: my new updated graph will only start to tell a different story from the original one, if we manage to bring down the annual growth rate of our CO2 emissions.

   So please help me make my new graph useful, by breaking the system that causes the emissions to go up with a steady 2.84% per year.

   > When it comes to climate comparisons, I think it isn't so simple as "trains use less fuel per passenger"

   Agreed, and this is where the rubber meets the road. If you accept the greenhouse effect, and that the planet is warming, then it's worth investing in things that aren't financially efficient, as long as they reduce carbon emissions.

   So the key question is, would a China-style fast train network in North America reduce carbon emissions?

   For 13 days earlier this year #Greenpeace activists bordered a #Shell #oil support;.

   Shell is now suing for over £2mn in damages, after court sanctioned negotiations broke down... because:

   Shell said they'd reduce the claim if Greenpeace no longer directly protests at/on Shell facilities/ships;

   Greenpeace responded they'd be willing to do that if Shell complied with a 2021 Dutch ruling requiring the to radically reduce emissions.

   So, now Shell is back to court to try & silence Greenpeace!

   What would happen if the richest 10% reduced their CO2 emissions to the EU average (which BTW is a nice standard of living).

   Answer, there would be a 35% decrease in global CO2 emissions.

   So, all would be fixed, if we could limit the excesses of the top 10%.
