Message : Required fields WINNIPEG, Manitoba (Reuters) - In the shadow of Canada's mega oil sands projects, smaller, technologically outdated facilities produce up to three times more emissions per barrel than the already high sector average- and rising oil prices have given them a new lease of life. These projects present another challenge to Canada's goal to cut emissions by 40-45% by 2030. With oil prices near 2-1/2-year highs and dim prospects for building new projects in a world heading toward net zero emissions, operators are aiming to pump as much as they can from existing facilities - including from the most carbon-intense sites.
