Study: Oil sands GHG intensities falling

The upstream greenhouse-gas emissions intensity of bitumen from the Canadian oil sands has fallen on average since 2009 and will continue doing so through 2030, says a study by IHS Markit. During 2009-17, the study says, emissions from upstream operations per barrel of bitumen produced fell by 21%. A further 16-23% lowering of emissions intensity is possible over the next decade.
