Editor's note: Sept. 29 marks National Coffee Day in the U.S. Throughout September, Human Nature is publishing a series of reports on the Sustainable Coffee Challenge, a coalition working to make coffee the world's first sustainable agricultural product. This post is the second in the series.
This story follows Conservation International's (CI) director of sustainable coffee markets, Raina Lang, to Guatemala, with Mattea Fleischner, manager on Starbucks' global social impact team. They were in the country to see how coffee trees are grown and delivered to farmers as part of the "One Tree for Every Bag" commitment, which has raised enough funds to plant more than 30 million new coffee trees. The commitment is part of a nearly 20-year partnership between CI and Starbucks.
