Going green is about action. Explore how Unity fosters sustainability within the university and beyond.
What Makes A City Green?
What are green cities? A green city is a city that actively works to foster the health and well-being of its people and the natural environment. Often, we look at government policies, community practices, and infrastructure to determine whether a city is “green” or not.
However, the greenness of a city actually exists on a spectrum and is multi-faceted. There is no such thing as the greenest city. The greenest cities in the world are those that are doing more to be sustainable when compared to other cities. The greenness of a city includes the following factors and more:
- The availability of green spaces
- Public transportation options
- Bikeability
- Renewable energy options
- Carbon footprint
- Recycling programs
What Makes A University Green?
An eco-friendly city and an eco-friendly university have a lot in common, including sustainable buildings, community farms and gardens, and ethically sourced goods. For Unity Environmental University, an essential part of going green was completely divesting from fossil fuels and investing in renewable clean energy instead. Ultimately, being a green university is about prioritizing sustainability as a core value and guiding principle for the institution.
12 Greenest Cities In The World
Urban areas around the world are striving to become more environmentally friendly as we continue to grapple with the negative effects of climate change. Many of the world’s greenest cities focus on mitigating those effects by minimizing their carbon footprint, shifting to renewable sources for energy, and improving public transportation. Other cities are taking innovative approaches to integrating green spaces and urban farming.
This list of the top 12 greenest cities is the result of a holistic review of the most environmentally friendly urban areas in the world. They are not listed in any particular order.
Singapore
Singapore has some of the lowest rates of air and water pollution in the world. The city also enforces energy efficiency standards for buildings and vehicles, and it has a carbon tax. What makes this green city truly stand out as a leader in sustainable urban development is its green spaces. Singapore has hundreds of miles of hiking and cycling trails, and the Garden by the Bay is known worldwide as a horticulture masterpiece. These green spaces not only provide residents with beautiful natural spaces in their own neighborhoods but also improve environmental conditions by mitigating heat and enhancing biodiversity.
San Diego, California, U.S.A.
California has stricter environmental regulations than most other states in the United States. This means cities in California, including San Diego, are held to high standards on building codes and vehicle emissions. San Diego stands out from other green cities in the U.S. for its goal of 100% renewable energy by 2035. The city receives more sun than almost any other in the country, making solar power very effective. Other sustainability efforts unique to San Diego include stormwater collection at the airport and water conservation initiatives for residents and businesses.

This emphasis on sustainable transportation helps reduce carbon emissions and air pollution. This, in conjunction with other sustainability efforts, earned Oslo the number one position on the 2022 Arcadis Sustainable Cities Index.
Zurich, Switzerland
If you want a great example of what a thriving green city looks like, visit Zurich, the largest city in Switzerland. Approximately 90% of Zurich’s power grid uses renewable energy, which is impressive for a metropolitan area with over 1 million people. It’s easy to make eco-friendly choices here with many zero-waste and plant-based restaurants to choose from. There are also free bikes for residents and visitors to use. They are placed strategically throughout the city. Lastly, Zurich has a mission that by 2050, the city’s energy consumption will only be 2,000 watts per person per year.
