Increasing urban densities can help reduce carbon emissions, but current efforts to make cities denser have not been successful. To address this, a new strategy called the Anatomy of Density II has been developed. This strategy breaks down urban density into seven factors and provides a comprehensive approach to making room for affordable city densification. By addressing each of these factors, cities can effectively and affordably increase their density. The strategy has been tested in real-world examples, showing both successful and failed applications.
