The Globe and Mail reports in its Friday edition that National Bank of Canada and CIBC have committed to measuring how their fossil-fuel financing compares with how much money they direct toward renewable energy, but not to making those numbers public. A Canadian Press dispatch to The Globe reports that the energy supply ratio measures how banks support or obstruct the transition to a low-emissions economy. National Bank says it agreed after talks with advocacy group Share to develop and disclose its own methodology for the measure by April 1 next year. It did not commit to disclosing the actual ratio though. CIBC also recently announced that it had started tracking the measure internally, and released details on how it calculates the ratio. Last year, CIBC asked shareholders vote against a Share proposal pushing it to adopt the measure, but said in its latest sustainability report that it will consider the ratio alongside other climate-related metrics. CIBC said, "We acknowledge the importance of the [energy supply ratio] to our stakeholders." The moves mirror Royal Bank of Canada, which, after pressure from U.S. pension funds, pledged to calculate its ratio but said last year it would not disclose the findings.
