Using the campus as a living testbed, the Institute has studied every aspect of its operations to assess their climate impacts, including heating and cooling, electricity, lighting, materials, and transportation. The studies confirm the difficulties inherent in transforming large existing infrastructure, but all feasible reductions in emissions are being pursued. Among them: All new purchases of light vehicles will be zero-emissions if available. The amount of solar generation on campus will increase fivefold, from 100 to 500 kilowatts. Shuttle buses will begin converting to electric power no later than 2026, and the number of car-charging stations will triple, to 360.
