In order to approach climate change as an opportunity rather than a threat, the City of Rotterdam launched the Climate Proof program in 2008. As a city, situated in a low-lying delta, with Europe's largest international port, Rotterdam has developed sustainable water management systems to fight climate change consequences -rising sea level, increases in cloud bursts, extremes in river water levels, longer periods of drought and higher temperatures. The Rotterdam Climate Proof program is based on three pillars: knowledge, action and communication, and aims to ensure that Rotterdam is “climate proof” by 2025. Implementation of new technologies and solutions in the framework of the program are enhancing the safety and the quality of life in the City, while offering considerable economic potential to the entire region. Innovative measures like green roofs or flood controlling water plazas are positioning Rotterdam as leading national and international water savvy and climate city.
