[From Website] Recognizing the extraordinary challenge of carbon neutrality and in preparation for updating its Climate Action Plan by 2012, the Seattle Office of Sustainability and Environment (OSE) commissioned SEI and its partners at Cascadia Consulting Group and ICF International to develop a scenario of how the city might be able to achieve carbon neutrality…
The scenario results suggest that implementation of a full suite of emissions-reducing strategies could cut Seattle’s per capita GHG emissions by 30% by 2020, 60% by 2030, and 90% by 2050, relative to 2008 levels. These reductions would require:
• Shifts to less GHG-intensive travel modes such as ride sharing, transit, walking and biking lead to 30% less per-capita travel by light duty vehicles in 2030 and 50% less by 2050, relative to 2008 levels.
• Dramatic increases in energy efficiency in building design and operations, as well as in vehicle efficiency, result in over 30% energy savings by 2030 (per capita in residential, per square foot in commercial, and per-mile in vehicles) and over 50% by 2050, relative to 2008 levels.
• Transitioning homes, businesses, and vehicles to lower-carbon energy sources: electricity (or possibly hydrogen) in the long run, biofuels as a bridging strategy for transportation until electric vehicles predominate, and to a much lesser extent, sustainable biomass sources (for district energy systems)…
