It's the net emissions that are problematic. Lower intensity results in lower carbon fees making the disincentive from producing FF that much less.

Who confirms the rate? The proponents or a third party?
Petra Nova claimed fantastic success, but on closer inspection, it was 55% of their target. Similarly, Snøhvit and Slepnir, and Gorgon have all hade major issues that were only discovered by unbiased evaluations.

The ill-fated Petra Nova CCS project: NRG Energy throws in the towel
NRG Energy Inc. just sold its 50 percent stake in the world’s largest carbon capture plant for only about $3.6 million, less than a half-percent of the Texas project’s roughly $1 billion construction ...

I'm game to put in a long bet that the grid interties are intended to decrease emissions intensity of oilsands rather than promote renewables.

Long Bets
The Long Now Foundation fosters long-term thinking. Our work encourages imagination at the timescale of civilization — the next and last 10,000 years — a timespan we call the long now.

Industrial carbon pricing and interties would likely have happened any way.

Even if this is just an approach to mollify Alberta, the second order impacts sends a clear signal - drill now, pay the consequences later.
Once we're ready to line up at the renewable energy starting line, other countries will have already passed the finish line.

Plants exist in equilibrium from abiotic factors, CO2 being one of them. There is only an apparent "capture" but that is due to disequilibrium between atmospheric and biospheric carbon flows (to my best understanding).

It depends on a lot of soil factors, but discing in Ag residue increases soil organic content. Labile carbon is lost, but a lot is recalcitrant and helps increase subsequent plant growth while also assisting in soil moisture retention from precipitation.

Note on carbon flow: ag residue isn't carbon capture and it sequesters in the wrong direction: from a long term sink (the ground, increasing soil carbon) into a short term sink (buildings).
