Hi there! It’s great that you want to come along on a climate tour of Zurich. It will teach you how people here in Zurich do lots of things to protect the environment – they save electricity and try to stop producing lots of nasty exhaust fumes. You will have a special guide to explain and show you everything that’s happening. Just be very quiet for a moment, and we’re sure that you’ll hear him.We also invite you to participate in our contest. Solve the puzzle as you go and perhaps win a prize.
