Coffee is grown widely along a tropical bean belt stretching across Central and South America, Africa and Asia. Brazil alone produces over two million tonnes a year and global production now tops ten million tonnes annually---over two billion cups of the stuff every day. Coffee's life-cycle carbon footprint ranges from around 70 grams per cup for instant to as much as 150 grams per cup for filter coffee. Major pests and diseases like leaf rust and the coffee berry borer are predicted to become even more prevalent under a future climate. In the highlands of Ethiopia---coffee's birthplace---warmer and wetter conditions in the future may allow fungal diseases to spread to higher altitudes and so threaten areas that are so far fungus free. Moving farms uphill, using shade and irrigation, and potentially switching to new hybrid varieties can all boost resilience and help reduce emissions. Access to training, advice and technology remains a major barrier to this for many coffee farmers.
