Deutsche Post has rolled out 100,000 "bio-sourced" payment cards for its enterprise customers called Postcard Gogreen. The cards can can be used to pay for the mailing of letters and packages and for express deliveries. They are made by Gemalto with the same physical format and characteristics as common payment cards, but made from a renewable material derived from corn, sugarcane and potato starch that is said to be easily recyclable and compostable (and with a dash of salt, a crunchy treat).
Gogreen is Deutsche Post's climate protection program. Its goal is to reduce CO2 emissions for every letter and parcel sent, and across all of its operations including subcontracted transportation services.
