A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

Compost weight is the sum of what is produced on main campus as well as the University Farm, using a standard volume to weight conversion.

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

A brief description of the institution’s GHG emissions reduction initiatives:

CWRU has invested heavily into mechanical system upgrades and lighting retrofits since the signing of the Presidents Climate Commitment in 2008, including phasing out the need for heating oil on campus. In conjunction with improvements to the electric grid, electric efficiency has increased while electricity emissions have declined over the last 10 years. The steam CWRU purchased historically was sourced entirely from coal, but in FY2017 switched to natural gas, which caused an emissions reduction as well. There were fewer degree days in FY2015-16, which Facilities was able to take advantage of when heating and cooling buildings.

Furthermore, better data tracking for data elements such as refrigerants and fertilizer has brought the GHG inventory closer to reality. Back in FY2009, information provided were estimates from people within Facilities.

Data source(s) and notes about the submission:

There is a significant change in scope 1&2 emissions from baseline to current. This data has been third-party validated. A great deal of work has been done and investments made on campus to make buildings more efficient and to reduce the energy intensity of campus.
