Columbia University is taking action to reduce our carbon footprint. If we lead by example, we will improve the sense of responsibility felt by our community for their actions through both education and demonstration. Ranging from energy conservation efforts, to award-winning reuse programs and recycling efforts, Columbia is fully dedicated toward creating a greener, more sustainable planet for all.  

At Columbia, we recognize that to be truly sustainable is to take a multi-faceted and multi-tiered approach. We are looking to tackle these issues through world-renowned research occurring right here on our campus, engaging staff leadership and individual participation.

Reduce, reuse, and recycle

Learn what you can recycle at Columbia. Donate and swap unwanted items during Clean + Go Green and Give + Go Green events. Use the surplus re-use program to donate or re-use office furniture and equipment. Taste, don't waste — practice mindfulness when selecting food in the dining halls and other eating establishments around campus. Wasting food wastes the energy and water used in producing and transporting it.

What to throw, and where?

Understanding proper waste segregation is crucial to a successful recycling program at Columbia.

The more Columbia recycles, the more we save money and contribute to a sustainable environment. Environmental Stewardship works with campus partners such as Environmental Health and Safety and Columbia Facilities to improve the University's recycling efforts. In recent years, the community recycled hundreds of tons of mixed paper and cardboard, 155 tons of electronics, 45 tons of lamps, 20 tons of batteries, tens of tons of glass, metal, and plastic, and much more. Check our Programs and Initiatives database for more about Columbia's waste and recycling initiatives.
