In 2014, the United Nations General Assembly established the celebration of World Cities Day on 31 October, an initiative to reflect on the future of cities and focus on the global urban challenges to create sustainable, inclusive and safe cities and communities. 

FCC observes this day as proof of its commitment for over 120 years to the development and transformation of the cities in which it operates, launching projects and initiatives in the area of corporate social responsibility and making the sustainability of its business model tangible through support to Sustainable Development Goal (SDG) No. 11. FCC supports this SDG by investing in innovation processes applied to its different lines of business so that, by managing their activities, they contribute to the creation of the cities of the future, to improve people's quality of life and to promote the sustainable development of society, providing solutions that help to improve adaptation to its impacts and protect biodiversity. 

The achievement of the 17 SDGs of the 2030 Agenda, approved in 2015 by the UN, continues to be part of the FCC Group's daily activities. In relation to its commitment to be a part of the solution it proposes, the Group's Board of Directors approved in 2016 the provisions of its Corporate Social Responsibility Policy, with its subsequent development by the Fourth CSR Master Plan for 2017-2020. It includes a company commitment to being a part of the solution to social, economic and environmental challenges, with this commitment focusing on responsible management and following recommendations 53 and 54 of the CNMV Code of Good Governance. 

FCC's vision is to contribute to the development and progress of cities, creating value for all citizens and also for its customers, shareholders and collaborators. A centuries-old corporate culture and solid values make it possible for FCC's businesses to grow on the basis of long-lasting, transparent and mutually beneficial relationships with those stakeholders with which the Group interacts. FCC's performance and commitment in each of its business areas, implementing its sustainable strategy and its circular economy model, allows the company to actively guarantee the implementation of sustainable guidelines in cities, reducing high energy emissions, improving citizen safety, and responding to the development and progress of the local communities where it operates, while generating value for its stakeholders and future generations.  

FCC is a leader in designing the sustainable cities of the future. This includes actions and initiatives to develop new abilities in the company, aimed at creating more sustainable solutions, providing more energy-efficient and less resource-consuming services, and incorporating value added innovations to the services provided by the company. This axis, therefore, deals with projects on the circular economy, the Climate Change Strategy, water impact and the protection of biodiversity, among other things.

According to the United Nations' report published in June 2019, the world population is expected to increase by 2 billion people, from 7.7 billion today to 9.7 billion by 2050. Furthermore, it mentions that, currently, 4.5 billion people, that is, 55% of the world's population, live in cities and the urban population is expected to reach 6.5 billion by 2050. In this scenario, sustainable development and new technologies will be the main vector to adapt the conception and planning of cities to this growth model.
