Internationally Recognized for Its Urban Planning and Sustainability, the Parana Capital Combines Innovation, Exemplary Mobility, and Green Areas That Even Exceed European Standards, Consolidating Curitiba as a Global Reference in Smart Development and Quality of Life.
The Parana capital has achieved a historic milestone by being elected the smartest city in the world in 2023 at the Smart City Expo World Congress in Barcelona. The international recognition reinforces Curitiba’s trajectory of innovation, sustainability, and urban planning, which for decades has served as a model for urban centers on different continents.
In addition to leading the global ranking of smart cities, the Parana capital stands out for its pioneering spirit in mobility and the impressive ratio of green areas per inhabitant, which significantly surpasses the standards recommended by the World Health Organization (WHO).

How 5,000 Indian dabbawalas manage to deliver around 200,000 lunchboxes a day in Mumbai for over 130 years using bicycles, crowded trains, and a manual system that continues to operate with impressive accuracy.
The city has accumulated international awards in areas such as sustainability, technology, and social innovation, garnering seven recognitions in less than a year.
Among the highlights is the Vale do Pinhão, an innovation ecosystem that has propelled startups that became unicorns, such as iFood, Madeira Madeira, and Alist.
The municipal program is considered one of the engines of sustainable economic development in the southern part of the country.
The urban intelligence of Curitiba is not limited to technology, but extends to how the city integrates sustainability, mobility, and social inclusion into long-term public policies.
Electric mobility projects, smart cameras, and digital inclusion initiatives reinforce the city’s reputation as a model of efficient governance.
Transportation System That Inspired the New York Model
One of the most emblematic symbols of the Parana capital is its public transport system.
Created in 1974, the Bus Rapid Transit (BRT) was the first system of its kind in the world and has become a global reference for efficiency and sustainability.
With exclusive bus lanes, tube stations with level boarding and prepaid payment, the system revolutionized the concept of urban public transport.
The Curitiba model has inspired over 180 cities around the world, including New York, which adapted elements of the BRT into its urban mobility system.
By 1999, Curitiba’s public transport already served 75% of the population, with capabilities and speeds comparable to subway lines.
The bi-articulated buses, capable of carrying up to 250 passengers, have established the system as one of the most efficient in the world.
Ecological Capital with Over 50 m² of Green Space per Inhabitant
Known as the “ecological capital of Brazil”, Curitiba combines urban development with environmental preservation on a scale rare among large metropolises.
The city has over 80 million square meters of green areas, which equals about 52 m² per inhabitant — a number far exceeding the minimum of 12 m² recommended by the WHO.
Parks such as Jardim Botânico, Parque Tanguá, and Parque Barigui are examples of public spaces that symbolize the balance between urbanization and nature.
The culture of sustainability is deeply rooted in the identity of the Parana capital, which has promoted selective waste collection since the 1980s and continually invests in environmental education and recycling.
In 2015, Curitiba was elected the most sustainable city in Latin America by Siemens’ Green Cities Index, reinforcing its ecological vocation and prominence on the international stage.
Curitiba as a Global Reference of Smart City
The combination of urban planning, technological innovation, and environmental preservation has transformed the Parana capital into a living laboratory of urban solutions.
The management model of Curitiba has been studied by universities and replicated by public managers in different countries.
Moreover, the Smart City Expo Curitiba, the local version of the international event, set a record for attendance in 2025, gathering 21 thousand visitors from 25 countries and generating R$ 650 million in business.
The success of the Brazilian edition reinforced Curitiba’s position as a key player in the global debate on the future of cities.
More than being smart, the Parana capital is an example of human and sustainable planning, capable of aligning economic growth, quality of life, and environmental responsibility.
