The new targets include a plan for a 35% reduction in so-called Scope 1 and 2 emissions intensity from the oil and gas sector, those linked to clients' own operations and energy use.
Intensity is a measure of emissions per unit of output.
"Ultimately, the achievement of our Scope 3 target range will require a concerted effort from consumers, industries and governments globally," RBC said in a statement.
For the power sector, RBC said it was targeting a 54% reduction in Scope 1 emissions, while for the automotive sector it was aiming for a combined 47% reduction in Scope 1, 2, and 3 reductions.
