6 ways cities can reduce their carbon footprints. A sustainable city is an urban center that has a net-zero carbon footprint. Find out how public transit, smart energy management, and waste removal help make a city green.
Cities don’t have to be dense smog centers full of loud traffic and trash. A new idea known as the sustainable city movement is challenging this traditional view of cities with innovative ideas such as edible landscaping, cycling highways, and more.
Read today 6 ways cities can reduce their carbon footprints and make your city a smart city of the future.
So what is a sustainable city exactly? It is one that has a net-zero carbon footprint by addressing challenges such as pollution and waste removal. More than just an eco-center, though, it is also a city with a sense of place and identity – somewhere its citizens are proud to call home.
Read on to learn more about the popular features of sustainable cities.
Popular features of a sustainable city
Also known as eco-cities, these urban centers are designed specifically to address social, environmental, and economic impact. Through smart urban planning, city management and strategic partnerships change is possible.
1. Affordable public transportation
Today, 75% of the carbon monoxide pollution in the U.S. is caused by motor vehicles. Sustainable cities need to cut down on the number of gas-powered vehicles on the roads in order to achieve cleaner air and less pollution.
Well planned public transportation can transform an entire city: take New York City or Toyko as examples.
As new transportation technology becomes available so does new inventive ways to transport the public. In recent years maglev trains have improved rail travel by making it faster, more eco-friendly, and more efficient.
Here are some examples of public transportation:
- Electric trolleybuses
- Maglev trains
- Metro systems
- Underground railways
2. Vehicle charging stations
Another way to reduce air pollution on the roads is to have drivers transition from gas to electric power. In order to do so on a massive scale, cities will need to build vehicle charging stations so electric vehicles have places to charge throughout the city infrastructure.
Hydrogen-powered vehicles are another new technology that may help cities be carbon neutral in the future. These vehicles will also need their own refill stations but rather than needing a charge, they need a refill of hydrogen and oxygen to run.
3. Walkable/bikeable neighborhoods
The most eco-friendly way to travel is on foot or on a bicycle, but in order for citizens to ditch transit in favor of these methods of travel, there has to be good walkable and bikeable infrastructure in place.
In Copenhagen, bicycles outnumber cars more than five to one thanks to major investments by the government to transition it into a cycling city. There are cycling superhighways, bike-only bridges, and bike paths all around the urban center to make bicycling as convenient as possible for its residents.
Here are some of the ways cities can make their streets more walkable and bikeable:
- Pedestrian bridges
- Bike path networks
- Connected urban grids
- Shared micro-mobility
4. Public greenspaces
Free green spaces for residents to enjoy is another essential ingredient of a sustainable city. While parks and trails will encourage people to explore the city on foot more, sustainable cities are investing even beyond traditional green spaces.
Edible landscaping, community gardens, and other urban farms can help solve hunger issues for residents in need while encouraging residents to eat farm-fresh and local ingredients.
5. Water conservation
Did you know that over 90% of the world’s cities are near coastal areas? Rather than polluting these water sources, cities should be finding creative and eco-friendly solutions for these waterways.
Restoring wetlands and planting trees can help protect a city from flooding, reducing the need for manmade flood infrastructure such as levees.
Rainwater harvesting can reduce water waste while irrigating public greenspaces and municipal buildings.
6. Waste management
Sometimes fines and regulations are the best ways to enact change. Take San Francisco, where recycling and compost mandates have helped Silicon Valley achieve a waste diversion upwards of 77%! Or take Australia’s COVID recovery plan to remake how they handle waste, which will create 10,000 jobs in the middle of an economic downturn.
Cities should prioritize going paperless with government documents and focus on energy recovery as well.
