Thanks for the informative article. This is a subject worth watching:

"The growing north-south tilt of North America's oil infrastructure puts a bigger onus on Canadian policymakers to make their voices heard in the U.S. The oil sands' growth could be threatened if the U.S. adopts policies aimed at curbing emissions during production, since oil sands production is higher in emissions.

Some members of Congress want to replicate California's plan to impose low-carbon fuel standards that target not just tailpipe emissions but also those that occur during production. That could put a surcharge on oil sands crude — unless producers can figure out a way to curb their emissions. "
