Modern megacities are increasingly facing the problems of pollution, overcrowding, and a lack of green spaces. In such conditions, the sustainability of the urban environment is becoming not just a trend, but a critical factor in the quality of life.

According to the Green City Index study published by the Daily Mail, there are already cities in the world that demonstrate how to combine urbanization with nature without harming the environment. The ranking takes into account several indicators at once: from air quality to the development of ecological transport.

In this article, we will look at how the ranking was formed, why Oslo became the leader, and what other cities are among the top 10 greenest in the world.

Are you planning a trip to Europe by car?

In many countries, highways are tolled and require an electronic road vignette. This is a digital permit that confirms payment for the use of toll roads and is checked automatically by the license plate number - without stickers and paper receipts. Making a vignette online before you travel will help you avoid fines, travel delays, and unpleasant situations during inspections.

How was the rating formed and what criteria were taken into account?

To objectively determine the world's greenest cities, researchers used a comprehensive approach. The ranking is not based on a single indicator, but on a combination of several key factors that directly affect the quality of life in a city.

Both environmental parameters and the level of urban infrastructure development were taken into account, which allows us to assess not only the state of the environment but also the comfort of living for residents.

The main evaluation criteria included:

1. Air quality - one of the most important indicators affecting public health

2. Number of green areas - parks, forests, squares and natural areas within the city

3. Accessibility of open spaces - how easily residents can get to green areas

4. Development of ecological transport - availability of public transport, bicycle infrastructure, electric vehicles

5. Overall comfort of the urban environment - the balance between buildings, nature and infrastructure

It is the combination of these factors that allows us to form a complete picture of how suitable a city is for a healthy and comfortable life.

Oslo is the most environmentally friendly city in the world

The capital of Norway confidently topped the ranking with 77.3 points out of 100 and became an example of how a modern city can develop without harming the environment. Despite being a large metropolis with a population of over 700 thousand people, Oslo has managed to maintain a balance between urbanization and nature.

One of the main advantages of the city is the accessibility of green areas. About 95% of residents have access to parks and natural areas within 300 meters of their homes, making outdoor recreation a part of their daily lives.

Oslo also demonstrates high air quality standards due to the active development of eco-friendly transportation and emission reduction. The city is actively developing its electric vehicle infrastructure, and public transportation is environmentally friendly.

Among the unique initiatives is the so-called “bee route” created to support the pollinator population. It is a system of green areas, flower gardens, and roof gardens that form a safe space for bees within the city.

Another interesting feature is the development of “pocket parks”. These are small green spaces that appear on the site of former parking lots, gradually changing the urban landscape in favor of people, not cars.

Top 10 greenest cities in the world

In addition to Oslo, the ranking includes nine other cities that demonstrate a high level of environmental friendliness, well-thought-out infrastructure, and comfort for living. Most of them are European capitals, but the list also includes representatives of Australia and Asia, which confirms the global trend towards sustainable development.

Here is the full list of leaders:

1. Oslo, Norway

2. Vilnius, Lithuania

3. Helsinki, Finland

4. Vienna, Austria

5. Canberra, Australia

6. Sydney, Australia

7. Stockholm, Sweden

8. Singapore

9. Reading, United Kingdom

10. Munich, Germany

These cities combine an effective environmental policy, the development of green areas and a modern transportation system to reduce the negative impact on the environment.

It is noteworthy that the ranking includes both compact European capitals and large megacities. This proves that a city's environmental friendliness depends not on its size but on its strategic approach to development.

Other environmental leaders in Europe

In addition to the cities in the global top 10, there are a number of other European cities that are actively implementing environmental solutions and gaining international recognition. These are both large cities and smaller urban centers that demonstrate high standards of sustainable development.

One such example is Heilbronn, Germany, which was named European Green Capital 2027. The city was recognized for its comprehensive approach to the environment and efficient resource management.

Among Heilbronn's key achievements:

- High air quality

- Efficient water use

- Reducing noise pollution

- Adaptation to climate change

- Development of a circular economy

Cities that have received the European Green Leaf Award, a distinction for smaller cities with a population of up to 100,000 people, also attract special attention.

Among them:

1. Assen, the Netherlands

2. Siena, Italy

These cities demonstrate that even without the status of a megacity, significant environmental results can be achieved by implementing local initiatives and effective urban strategies.
