A staggering 68% of the world’s population will live in cities by 2050. This shift calls for a new approach to smart green city planning, one that can meet rising energy demands without placing additional strain on financial or environmental resources.
Cities that have already embraced intelligent technologies provide a glimpse of what is possible. Copenhagen has recorded an impressive 75% reduction in emissions since 2005, supported by renewable energy programs and forward-thinking urban policies. Shenzhen offers another compelling example. Its use of artificial intelligence in traffic systems has lowered CO₂ emissions by 20%, and its adoption of smart meters has reduced energy use by 15%, saving more than 1.6 TWh each year.
