    Drivers of change

United Nations
 “…anthropogenic warming has had a
 discernable influence on many physical
 and biological systems…”

 Greenhouse gas emissions contribute to
 warmer temperatures, fewer cold days,
               p                        y
 increasing f             f
             frequency of warm spells and
 heat waves, expansion of drought,
                             storms,
 intensification of tropical storms rising
 sea levels…

Climate is Changing
Global Implications
  Implications

New demands on the performance of
built environments
New considerations for the design and
operation of buildings and communities
 p                  g
New risks and liabilities for developers,
owners, and operators
  Motivations for Action

Public policy
Legal action
Public opinion
Disclosure
Standard of care
Potential regulation
  Global Warming Solutions
  Act
  A t (AB32)
Economy-wide cap on greenhouse gas
emissions
Enforceable emission reduction goals,
starting with 25% by 2020
       g            y
Bottom line: California has articulated a
state wide
state-wide goal for addressing climate
change.
     Public Opinion

Sample of recent polling results (April 2007)
  Fox: 82% believe global warming exists
  Washington Post: 86% think global warming
  is a serious problem
  Gallup: 61% believe the Earth’s temperature
  has increased due to human activities
  CAP: 60% want immediate action
  CBS/NYT: 75% willing to pay more for
  renewable electricity
  Yale: 62% support more laws to enforce
  energy efficiency
