MIT’s Sustainability Challenge






MIT uses over 375 million gallons of water annually
Generates over 11,500,000 lbs of trash per year
…and over 338,000 lbs of chemical waste per year
Produces thousands of cu/ft of other regulated lab waste
19% of MIT community drives to campus alone
But 81% take the T, carpool, bike, walk, etc. versus 24%
nationally
 Of over 200 campus vehicles, less than 10 use alternative
fuel
 Feeding a community of over 10,000
 Energy, energy, energy…

What is MIT Efficiency Forward?
 Long-term partnership for promoting energy efficiency and
conservation investments - seeking to develop new approach for state
goals
 3 year collaborative framework
 A 34 million kwh electricity reduction commitment (a 15% reduction)
 A mix of funding sources: MIT capital, NSTAR incentives, reinvestment of savings
 $14 million of work estimate to save over $50 million
 A mix of:
 New construction enhancements
 Existing building retrofits
 Behavior change measures
How are we going to reach our 34+m kWh goal?

Enhances Our Campus as a Living Lab
 Partnering with Academy focuses priorities, deepens
progress, expands our value, broadens and builds
relationships, opens door to new resources
 Position campus as living, learning laboratory advances core
academic mission & improves solutions
 Partnerships focus on campus operations
 Campus Energy Task Force
 Campus Sustainability UROPs
 Student Campus Energy Project Grants
 Class project-based learning opportunities
 Graduate and undergraduate theses
 FPOP – Discover Energy: Learn, Think, Apply
Unanticipated partnerships can also bear fruit
