Today we examine an amazing new tool called "Trase", which launched at year-end climate talks in Marrakesh, Morocco. It shows you something we've always known was there, but could never see: namely, 320,000 supply threads, going from individual municipalities in Brazil, through local brokers, to importers in countries around the world.
