Hydroelectric Vs. Tar Sands

We get the following from Preston Manning over the weekend:

Preston Manning is calling out "hypocritical" federal NDP Leader Tom Mulcair for "preaching" to Alberta while turning a blind eye to energy problems in Quebec.

[...]

The problem with Mulcair's position, Manning said, is that the former Quebec minister of sustainable development and the environment has never been heard "crusading to internalize the impact of Quebec's hydro operation."

Manning told Solomon hydro companies have flooded forest areas "the size of lake Ontario," so "where is the reservoir tax that's the hydro equivalent of the carbon levy?" Manning asked.

Fair enough.  But lets follow the logic of this thinking.

That hydro projects can have fairly large scale emissions of GHGs associated with them is fairly well known.  In fact, in the run-up to its 2006 discussions the IPCC considered having countries add emissions from lands flooded by new hydroelectric projects (meaning 10 years old or less) to their National Inventory Reports, which reports show each country's carbon budget.  And indeed if you look at Canada's report (submitted in April of 2011), you will see (in Part 2) that:

Total CO2 emissions from the surface of reservoirs were estimated as the sum of all emissions from reservoirs flooded for 10 years or less.


It is important to understand the "10 years or less" stipulation.  The graph below shows what happens to GHG emissions from hydro projects (at least in the Canadian context; dams in tropical locations are a somewhat different story):

That is to say, peak emissions (from drowned vegetable matter) occur in the very first couple of years after flooding.  Furthermore, if you look at the total amount of Lands Converted to Wetlands (Flooded Lands) in Canada over the period of the report (1990 to 2010) you get this:

...mostly because the building of Hydro-Quebec's large projects came to an end in the 1980s and 1990s.

So the rule is to stop counting emissions after the first decade.  And therefore, at present, the majority of hydroelectric projects in Quebec, assuming your reservoir tax is connected in some reasonable fashion to emissions as counted in the national inventory, would evade the tax or pay very little.  Furthermore, even newer projects like Eastmain-1 would only be subject to a tax for the next couple of years, its reservoir having been completed in 2006.

So you might defend Mulcair here by saying he isn't promoting a reservoir tax because its usefulness  in "internalizing the impact" of Que.'s hydro would be minimal, because that impact has itself become minimal as time has passed.

But there's a broader point to be made.  Quebec's investment in hydro-electric, though immensely controversial at the time, has led it to be well positioned in any discussion re cutting emissions.  There is no variant of a national cap-and-trade scheme in which Quebec would not come out a winner, for it has chosen an energy source that becomes greener (emits less) as time goes by.  On the other hand, nobody seriously expects the Tar Sands to be spewing fewer GHGs in 15 years.

They are not environmentally progressive in Quebec because they like trees and flowers, although I am sure they do.  They've chosen to run their province with an energy technology that allows them to be.
