Data source(s) and notes about the submission:
This inventory differs from OP-1 which uses 2019 data. We chose 2019 for OP-1 because completed a full scope 1, 2, and 3 inventory of the college.

OP-2 is based on 2021 data. It is the most recent year for which we have a scope 1 and 2 inventory. We did not conduct a complete scope 3 inventory in 2021. Barnard purchases Green-e RECS to cover all 100% of electricity usage.
