Emerging Global Economies
If China and India consume resources and pollute
at the rate of the United States current levels,
it will take ONE PLANET EACH to sustain their
economies

Global Ecological Footprint

• Average American footprint grew by 21 over past
  decade
• USA 24 acres per person
• Japan 10.6 acres per person
• Brazil 5.2 acres per person
• China 4 acres per person
• World's Ecological Footprint Exceeds Biocapacity

What is the LEED System?
Scores are tallied for different aspects of
efficiency and design in appropriate
categories. For instance, LEED assesses in
detail 1. Site Planning 2. Water Management 3.
Energy Management 4. Material Use 5. Indoor
Environmental Air Quality 6. Innovation
Design Process
LEADERSHIP in ENERGY and ENVIRONMENTAL DESIGN A
leading-edge system for certifying DESIGN,
CONSTRUCTION, OPERATIONS of the greenest
buildings in the world
