Sustainable development of megacities

With innovative technologies, Brazilian megacities can become more environmentally friendly, increase the quality of life for their residents, and cut costs – all at the same time.

Latin America is the most urbanized region in the developing world. That is why there is a strong potential for a sustainable development in Latin American megacities. Approximately 80 percent of Brazil’s population (currently 196 million) lives in cities. The most densely populated urban centers are the megacities São Paulo with a population of 20.3 million and Rio de Janeiro with approximately 11.4 million. This increasing urbanization is forcing cities in Brazil and elsewhere to make their infrastructures more efficient and sustainable in areas like power supply and smart grid, as well as mobility and green building. In view of the upcoming mayor events security solutions are also getting increasingly more important.

At the UN Conference on Sustainable Development (Rio+20) in Rio de Janeiro in June 2012, participants expressed their commitment to sustainable development. More than 14,000 people from around the world visited the exhibitions at the UNEP (United Nations Environment Programme) Pavilion. There, Siemens set up and was involved in side events and thought leadership conferences. “The motto of Siemens at Rio+20 was ‘We can act now.’ UNEP fully supports this call for action”, said Achim Steiner, UNEP Executive Director and Under-Secretary-General of the United Nations. Siemens launched a recycling and environmental education project on the Rodrigo de Freitas Lagoon and released findings in a first ever study about how Rio de Janeiro will look from 2030 to 2040. In an exhibition, our company showed how innovation supports sustainable development, and in the “Students for Sustainability” event, Siemens brought together international student teams to develop the next generation of sustainability leaders.

    Renewable energy for sustainable cities

    Megacities are major consumers of power. One way to satisfy increasing energy demand is to produce electricity using sugar cane.

    The intelligent power grid of the future

    In order to reliably supply power to cities in the future, the energy transported there must be sensibly distributed and efficiently used. The name of the solution is the smart grid.

    Efficient urban mobility

    São Paulo’s metro system transports four million passengers a day. Traffic management systems and the expansion of subway networks promise to help remedy congested streets and the declining quality of life in the inner cities.

    How to create a green building

    Buildings represent an enormous potential for energy savings and are the key to sustainable urban development. Building automation and light management as a part of a green building can drastically reduce energy consumption without affecting the inhabitants’ comfort.

Siemens is an international leader in sustainable development for cities, with concepts and solutions for power, smart grid, mobility, green building, security systems, and healthcare. A variety of Siemens initiatives promote ideas for a sustainable development in the city of the future. The Latin American Green City Index, for instance, shows just how sustainable Brazil’s cities are today. São Paulo sets a benchmark with zero CO2 emission from electricity consumption. In the Green City Index Summary Report Rio de Janeiro is highlighted as the city with the highest amount of green space per person, in spite of the high population density typical for megacities. And according to the study "Pictures of the Future Rio 2030-2040" by 2030 Rio can become the Latin American capital of business, tourism and high tech research and development hub.
