The built environment is the major source of global demand for energy and materials that produce by-product greenhouse gases (GHG). Planning decisions not only affect building energy consumptions and GHG emissions, but transportation energy consumption and water use as well, both of which have large environmental implications.
In 2008, Architecture 2030 issued The 2030 Challenge for Planning asking the global architecture and planning community to adopt the following targets:
All new and renovated developments / neighborhoods / towns / cities / regions immediately adopt and implement a 60% reduction standard below the regional average for fossil-fuel operating energy consumption for new and renovated buildings and infrastructure and a 50% fossil-fuel reduction standard for the embodied energy consumption of materials.
The fossil-fuel reduction standard for all new buildings, major renovations, and embodied energy consumption of materials shall be increased to:
70% in 2015
80% in 2020
90% in 2025
Carbon-neutral in 2030 (using no fossil fuel GHG emitting energy to operate or construct).
These targets may be accomplished by implementing innovative sustainable design strategies, generating on-site renewable power and/or purchasing renewable energy (20% maximum).
All new and renovated developments / neighborhoods / towns / cities / regions immediately adopt and implement a 50% reduction standard below the regional average for:
Vehicle Miles Traveled (VMT) for auto and freight
