From my linked report; A more energy efficient supply chain.
In 2015, we started engaging directly with suppliers to help them reduce their energy use. We aim to educate them about energy efficiency, identify energy efficiency project opportunities, and manage those projects to completion. We prioritize facilities with the highest energy use and potential for improvement. Then we conduct energy audits and train suppliers to uncover opportunities for energy efficiency—like replacing outdated or inefficient heating, cooling, and lighting systems; repairing compressed air leaks; and recovering waste heat. The assessments provide suppliers with a cost-benefit analysis for implementing energy efficiency improvements. Since the inception of this program in 2015, we have engaged 59 suppliers at 85 facilities. In 2018, our program implemented energy efficiency measures that prevented 466,000 metric tons of CO₂e from entering the atmosphere.
So they are working with suppliers and have been for the past 5 years. They also have been cleaning up the chemicals their suppliers use.
You can't compare what they are doing to murder; it's legal for starters. But if you're relying on all the companies you do business with to make up your definition of 100% renewable, it's likely you'll never get there. They don't say anything about the energy used by the banks they do business with either.
