The surprisingly low carbon footprint of a banana

"Both kiwis and bananas are shipped long-distance. But what is being grown—and the inputs (fertilizer, pesticide, heat) needed to grow it—often matters as much as where the growing happens. The point: Carbon footprints for food are, unfortunately, not terribly intuitive. To me, this is why we need some standardized system of carbon labeling. Right now, it's all but impossible for individuals to make decisions about the carbon footprint of the things they buy. You shouldn't have to be an expert, or tote a calculator and the proper formulas around with you."
