WHAT IS “SUSTAINABILITY?”
The ability to keep doing something for the indefinite future
If it’s not profitable, it’s not sustainable
What allows a company to survive? Meeting customer demands Developing new products Keeping costs low

Dimensions of Environmental Sustainability: Carbon: energy burned by us, by our suppliers Water: water used Paper and corrugated used Solid waste generated
Costs and Revenues: Lower electricity, gas and water bills Lower garbage hauling costs Better public relations
How much do customers care? If it makes them feel closer, there’s likely monetary value?
How much is your competition doing? Watch out for GREENWASHING!!!! Trivial gestures: attention misdirection – ski passes, plastic
bags
DIFFERENT METRICS
The Carbon Footprint of a plastic bag is 1/1000 that of the food in it!

Waste hauled by Castaway Trash Hauling Commercial composting Landfills emit methane, a bad GHG, and usually don’t
capture it Composting emits less methane 30-70% less
