Zero-carbon city

A zero-carbon city is a type of city that does not produce any carbon dioxide into the atmosphere. This means that the city generates no harmful gases or pollutants which damage the environment. To do this, this type of city uses only clean sources of energy like wind or solar power. It also uses energy efficient technologies and effective waste management systems to reduce their carbon footprint. Through their tools and methods, zero-carbon cities produce no carbon dioxide and work to reduce global warming.
