“pro clima” – Shipment
Carbon neutral at no extra charge for the customer: since 2012, Swiss Post has been sending all domestic letters carbon neutrally. In 2015, in collaboration with Genossenschaft Ökostrom Schweiz, Swiss Post funded the development of the first gold standard Swiss Post climate protection project in Switzerland for this “pro clima”–Shipment service. Modern biogas plants on Swiss farms collect methane, a greenhouse gas produced by the storage of liquid manure and dung, and use it to generate heat and electricity – thus turning methane, which is harmful to the climate, into a clean energy source for eco-electricity.
