Architects Call for 50% Cut in Fossil Fuel use in Buildings by 2010:
With such a short time frame, there must be a lot of "low-hanging fruit" in new construction. "The American Institute of
Architects (AIA) has adopted position statements to promote
sustainable design and resource conservation to achieve a minimum
reduction of fifty percent of the current consumption level of
fossil fuels used to construct and operate buildings by the year
2010. .. “Buildings account for forty-eight percent of U.S. energy
consumption and generate far more greenhouse gas emissions than any
other sector,” said R.K. Stewart, FAIA, facilitator of the AIA
Sustainability Summit Task Force. .. Fundamental to helping ensure actual results, the AIA also supports
the development and use of rating systems and standards that
promote the design and construction of communities and buildings
that contribute to a more sustainable and environmentally conscious
future. According to the AIA, an undertaking of this magnitude will require
a sustained effort over the next ten to fifteen years,
especially in educating clients about their role in the success of
this effort." 8:27:22 AM
US GHG emissions in 2004
: Reference numbers. "Petroleum is the leading source of GHG emissions from energy and industry sources, according to the Department of Energy. Oil emitted 2,592 Mt [metric tonnes] in 2004, compared with 2,180 Mt in 1990.
Combustion of coal for energy applications emitted 2,090 Mt in 2004, compared with 1,784 Mt in 1990, while natural gas emitted 1,203 Mt of CO2 in 2004 compared with 1,027 Mt in 1990, notes the DOE report, "Emissions of Greenhouse Gases in the United States 2004."
For all energy and industry sources, national GHG emissions in 2004 were 5,900 Mt, of which the residential sector emitted 1,212 Mt, the commercial sector 1,024 Mt, the industrial sector 1,730 Mt and the transportation sector was 1,934 Mt.
