A substance called biochar, which is made by cooking wood waste or other biomass at high temperatures without oxygen is getting a lot of attention in Minnesota. The resulting charcoal can store carbon dioxide for centuries.

This is an MPR News afternoon update, hosted by Elena See. Music by Gary Meister.
