They are overpaying for energy:

TORONTO, Nov. 23 /CNW/ – RBC today opened its 100th bullfrogpowered branch in Brantford, Ontario. RBC was the first financial institution to partner with Bullfrog Power to source low-impact, renewable power in 2005. The 100 Canadian branches powered by Bullfrog use 9,800 MWh of certified emission-free power.

“The decision to become bullfrogpowered at 100 of our branches supports our commitment to reduce our greenhouse gas emissions footprint across our operations,” said David McKay, group head, Canadian Banking, RBC. “This goal will be achieved through a combination of conservation and energy efficiency measures, as well as the sourcing of clean renewable energy like Bullfrog Power.”

RBC is committed to increasing the percentage of certified green power used in its Canadian branch network through purchasing clean, renewable green power for all new branches in Ontario, Alberta, British Columbia and the Maritimes, where Bullfrog currently has operations. In 2009, RBC opened 25 new green-powered branches in Canada.

 Apparently RBC also finances companies that invest in the oil sands, not that there is anything wrong with that. But it does seem to clash with their pretensions to be one of Canada’s greenest employers.
