Innovations for achieving the 2050 sustainability challenge for creating net zero emissions & livable healthy cities
How to meet t he 2050 challenge to achieve sustainable net zero emissions in cities 1. The challenge Buildings and construction globally are responsible for 39% of Greenhouse Gas Emissions (GHGE's) with 20% in New Zealand. Collectively, the energy used by buildings produces more pollution than transport and industry. There are high GHGE's for 'upfront' carbon emissions associated with materials, the construction process, heating and cooling processes, lighting, maintenance, fits outs, renovations and demolition. The majority now live in cities. Population numbers will explode by 2050 to 9.27 billion necessitating innovations to feed and house everyone. Skyscrapers provide vertical living (e.g, the Shard Building, London and the John Hancock Centre in Chicago where many thousands of people live, work and relax in one building), these are a Vertical Cities within a city (VC) however the design has high GHGE's....
