City officials Calcutta, Venlo and Vienna give an answer.

It was a meeting of mayors from around the world: at the second International "Mayors' Summit", around 75 delegates from 28 countries gathered in Düsseldorf to discuss opportunities and challenges for cities.

In order to make Calcutta more sustainable, we have developed public transport. We also rely on electronic mobility: electric cars, electric buses and electronic rickshaws. For new buildings, we will deduct a portion of the taxes if 20% of the land is planted with trees. "

The planted facades clean the air, bring biodiversity and refresh the environment in summer. The building reduces by 30% the proportion of particles suspended in the air, within a radius of 500 meters. All materials are recyclable. The construction cost 50 million euros. This is roughly equivalent to the annual cost of administrative staff. We pay only one percent of the annual energy costs. The focus on creating a healthy work environment is also profitable.
