The Green Corridors project in Medellin, Colombia, aims to tackle urban environmental challenges, particularly the urban heat island effect and high levels of air pollution, which are exacerbated by heavy motorbike traffic and extensive concrete surfaces in public spaces. The project focuses on improving air quality, cooling temperatures, and enhancing the city’s green infrastructure. This initiative is part of a larger effort titled "A Greener Medellín for You," aiming to make Medellin a more attractive, sustainable, and livable city.

Nanjing West Road, a prominent commercial street in Shanghai, has long been a hub of urban activity and cultural significance. Its recent upgrade incorporated Nature-Based Solutions (NBS) to address pressing urban challenges while promoting sustainability. The primary objectives of the project were to enhance urban ecological systems, improve the overall environmental quality, and create a harmonious blend of commerce, culture, and nature. By adopting NBS, the project aimed to mitigate urban heat island effects, enhance stormwater management, increase biodiversity, and provide multifunctional public spaces that cater to the needs of both residents and visitors.

Supplementary Cementitious Materials (SCMs) are materials that, when combined with Portland cement, enhance the properties of concrete through hydraulic or pozzolanic reactions. These materials can be industrial by-products, such as fly ash or slag, or naturally occurring substances, like volcanic ash. SCMs are used to partially replace cement in concrete mixtures, reducing the environmental impact of cement production while improving the performance and durability of concrete.
