The German city of Hamburg has banned coffee pods from government-run buildings. In an attempt to become more environmentally friendly, the city said it will no longer spend taxpayer money on products that don't meet its high sustainability standards.Coffee capsules, like those sold by the Nestle (NSRGY), Keurig (GMCR) and other brands, are specifically mentioned in the city's new guidelines, because they create unnecessary waste and contain aluminum. A spokesman for the city said the pods contain 3 grams of waste for every 6 grams of coffee. But the list of prohibited items goes far beyond coffee. It includes plastic cutlery and plates, water, beer, and soft drinks in disposable packaging, as well as certain cleaning products and even wall paints. "The city can help ensure that environmentally harmful products are purchased less frequently and that sustainable products achieve even greater acceptance in the market. Our objective is to increase the share of environmentally friendly products significantly in order to help combat climate change," said Hamburg senator Jens Kerstan.
