5 'TO VISIT 
PORTLAND, OREGON. The first city to be designated with the title of Bike-Friendly by the League of American Cyclists, and considered the greenest city in a survey which was based on renewable sources of energy, transport, recycling and green city. There are lots of green infrastructure in Portland, lots of city parks, including the World's Smallest Park, as certified by the Guinness Book of World Records.
Freiburg, Germany. Fribourg was the first experimental community green, designed several years ago, when the center of the city was rebuilt after the destruction of ecological principles in the Second World War. Visitors can see the section called Rieselfeld, the social community that is introduced, consisting in the '80s, or the famous Vauban district where no access to cars. Do not miss the Solar Village el'Heliotrop House, both designed by Rolf Disch.
ZERMATT, SWITZERLAND. A picturesque Swiss town at the foot of the Matterhorn, attracts nature lovers for skiing, hiking and mountain climbing. When it exploded tourism, the city has taken the decisione di non combattere la battaglia per mantenere le infrastrutture sufficienti per la crescita delle esigenze di traffico, ma di rimanere ai livelli antichi con strade riservate ai pedoni e alle biciclette. I carichi sono tirati per tutta la città a mano o trainati dai cavalli. Piccoli veicoli elettrici hanno bisogno di permessi speciali per circolare, e sono previste eccezioni solo per i veicoli di emergenza.
MONTREAL, QUEBEC, CANADA. Dal Protocollo di Montreal (che regola le emissioni dannose per l’ozono) al recente progetto di condivisione delle biciclette pubbliche, Montreal è una fucina di idee verdi. Dopotutto, una città a centinaia di chilometri dal più vicino oceano che vanta un surf club non may not have big ideas about his surroundings.
AUSTIN, TEXAS, USA. This is one of the city that has made energy efficiency home a real battle. The mayor of Austin has put sustainability at the top of the list of priorities of his mandate. Try to visit the ecological food festivals, the true identity card of the city.
