We use cobalt every day. It's in the lithium-ion batteries in our phones, and in the growing fleet of electric vehicles out on the road. But chances are more than good that at least some of the cobalt in your phone or EV is not ethically sourced. This week on Switched On, we talk with Kwasi Ampofo, a BloombergNEF analyst focused on metals and mining, about his recent travels in the Democratic Republic of the Congo. We'll hear about what he observed in the cobalt mines there, and what companies are doing to ensure ethical sourcing of this critical metal.

This episode is based on a report titled Solving the ‘Blood Cobalt’ Challenge for EVs.

BNEF clients can access this report on bnef.com or BNEF Mobile, or at BNEF on the Bloomberg Terminal.

Switched On is hosted this week by Mark Taylor and Dana Perkins.
