Changing the future starts by changing the city
The way we currently run cities is one key driver of environmental and health problems. All is not lost however, as it also means the solution to these problems lies within these cities. If we can move to more sustainable cities of the future, we can take complete control of environmental issues on a global scale. According to the UN, cities produce 75% of the worldâs greenhouse gas emissions. They expect in the next 15 years half of energy related emissions will be caused by only 500 cities. In the renowned magazine Nature, it was stated that more than 3 million people in cities die each year from air pollution, which is more than casualties from HIV/AIDS, Malaria and the flu combined. Moreover, expansion of cities worldwide causes rising of temperature, destruction of farmland, and massive floods. In order to change the future, we need to change urban life. The big question is: how? We have found a good starting point: Siemens has recently published the Green City Index. They evaluated 120 cities around the world and measured their environmental performance, on indicators that stretch from energy, sanitation, water, waste and air quality to transport, land use, and environmental governance. The extensive research resulted in a global ranking of world cities, and Siemens found a number of lessons from the most environmentally friendly ones. Letâs see what we can learn from them:
First of all, the key is to take a holistic approach. Collaboration between different sectors and city departments is essential. For instance, if we want to solve the problem of air pollution, we need health departments and transport departments to work together. Cities that understand this and facilitate collaboration in tackling the problems are achieving the most successful results. Copenhagen (leading the European Ranks) is a good example of a city with effective holistic environmental governance according to Siemens.
Secondly, we have to take a step further in collaborating with each other. Encouraging civic engagement in the cities efforts is essential. According to Siemens, there is a huge unused potential here. Luckily, more and more entrepreneurs and pioneers are taking the lead to involve the crowd in changing urban life (for example Rooftop Revolution, WeHelpen, Stadslab Buiksloterham). And finally, we have to use the right technology. The research takes the example of London, stating that they could âcut almost 44% of its CO2 emissions with the help of technologies without requiring the residents to change their lifestyle. Almost two thirds of these technological solutions would pay for themselves through energy savings. â.
Parkyourcar plans to work together with partners across all sectors and stay connected with the community so we can all play our part in building the cities of the future together!
