Tirana's Vision for 2030

Tirana, the capital of Albania, has developed a comprehensive plan called "Tirana 2030" to guide its sustainable development. Deputy Mayor Ky Larasi shared insights into the city's strategies for creating a more livable and environmentally friendly urban environment.

Polycentric Urban Development

Tirana's urban development plan focuses on creating polycentric areas within the city. The goal is to develop multiple "poles" or nodes where people can access everything they need within a 15-minute walking distance. This approach aims to:

• Reduce traffic congestion
• Decrease reliance on private vehicles
• Improve overall quality of life for residents

Sustainable Transportation

To address traffic issues and reduce emissions, Tirana is investing heavily in sustainable transportation options:

• Expanding pedestrian areas
• Creating an extensive network of protected bike lanes (58 kilometers implemented in the last 5 years)
• Developing green corridors to connect different areas of the city
• Implementing a Bus Rapid Transit (BRT) system with dedicated lanes

These initiatives are designed to change the mindset of citizens, encouraging them to leave their cars at home and opt for more sustainable modes of transport.

River Restoration: The Lana River Project

One of Tirana's most significant urban renewal projects involves the restoration of the Lana River. Previously covered by concrete and lined with illegal housing, the river has been transformed into a public asset:

• Illegal structures were removed
• The riverbanks were converted into pedestrian and cycling paths
• Green spaces and tree planting have been introduced along the river
• The area now serves as a recreational space for residents

This project, supported by the European Investment Bank, has not only improved the city's resilience to flooding but has also created a valuable green corridor through the urban landscape.

Sofia's Green Vision

Sofia, the capital of Bulgaria, is leveraging its natural assets and implementing innovative strategies to enhance its sustainability and combat climate change. Mayor Vil shared the city's approach to preserving and expanding its green spaces while working towards climate neutrality.
