Christchurch has become one of the most sustainable cities in the world since the 2010 earthquakes due to embracing green building standards. Commercial buildings are among the most energy efficient and have low environmental impacts and carbon emissions while also being economical to build. Tenants prefer these buildings and are willing to pay more. As a result, business owners enjoy improved financial stability and resilience. Christchurch now has low unemployment, high wages, and retains young people and entrepreneurs due to its sustainability driven economy and reputation as "Made in Sustainable Otautahi Christchurch". The low unemployment combined with good social services and arts has led to a strong sense of community and civic pride in Christchurch.
