The world population is expected to increase from 7 to 10 billion people by 2050, a fact which poses great challenges for life in cities around the world. Currently more than half of the population lives in urban areas, a share that is expected to reach 80% by 2050.

Faced with the rapid rate of urbanization, we must guarantee an inclusive transition that encourages the conservation of rural spaces and the promotion of the local economy. It is also essential to guarantee a healthy and quality life in cities by reducing pollution and promoting sustainable mobility.

Building and construction accounted for 36% of the energy use and 39% of energy related emissions. As one of the most important industries in cities, the transformation of this sector is critical to make cities sustainable places to live.
