Carbon Footprint as Environmental Performance Indicator

Your "carbon footprint" is the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels by a particular person, group, etc.
The video below profiles one small business with a "zero waste" mission. Waste prevention and recycling work together to shrink your carbon footprint in three important ways:
reducing emissions associated with the energy needed to produce and transport new products
reducing emissions from incinerators and landfills filled with our trash
increasing “carbon sequestration” in trees left standing when we use recycled paper

What are some other environmental performance indicators which may be used to offset an organization's carbon footprint?
Research and describe one organization that has implemented an EPI, and the impact it made on their footprint.
What steps (physical, behavioral, procedural, etc.) can you identify from your example which are critical to managing an organizational change initiative toward carbon reduction?
