Global smart cities present environmental opportunities. Digitization enables new solutions, and Finland could play a larger role than its size in addressing ecological and social issues. The biggest challenge is decoupling well-being and economic growth from natural resource consumption. Renewable, recyclable and biodegradable materials and eco-design principles are preferred over fossil fuels. Digital platforms promote increased sharing and extending product lifecycles through renting, reusing and recycling. Technological development enhances resource efficiency in production and recycling.
