Hope College
OP-1: Emissions Inventory and Disclosure

Natural Gas and Electrical emissions were calculated from 2005 through the calendar year of 2018.
In the emissions category of “commuting” the student and faculty commute was included for 2017. The faculty commute was calculated by assuming a daily commute to and from Hope College if he or she lives within a 60 mile radius. The distance from each city, in miles, per faculty member who fit the qualifications was accounted for a twice a day commute, over a period of 140 days. The 140 days is the amount of working school days in a calendar year. All student and faculty commute was assumed to be done by conventional gasoline vehicles. The conversions from the mileages to carbon dioxide equivalent use conversion factors from the Environmental Protection Agency’s website (www.epa.gov). For student and faculty commute the miles traveled were converted to gallons of gasoline consumed, then to British Thermal Units (btu), then to pounds of carbon dioxide emitted, then to short tons, and finally to metric tons.
In the emissions category of “other” the groundskeeping and vehicles owned by Hope College emissions were calculated using their gallons of gas they consumed. The conversions from the gallons of conventional gasoline and diesel gasoline consumed came from the Environmental Protection Agency’s website (www.epa.gov). For conventional and diesel gasoline the gallons consumed were converted to British Thermal Units (btu), then to pounds of carbon dioxide emitted, then to short tons, and finally to metric tons.

Up until 2017 we have been required to participate in the Michigan Air Emissions Reporting System (MAERS). We hired a third party firm to complete this report for the college.
This covers DeVos Field House and the campus boiler plant.
Source Summary Report - AQD Source ID (SRN) M4153 Reporting Year : 2017

During calendar year 2018 the HBPW obtained its energy from the following sources: Coal 25.1%; Natural Gas 55.5%; Renewables 12.1% (8.1% Wind and 4.0% Landfill Gas); and Market (various) 7.3%.

2018 marked the first full year of operation for the award-winning Holland Energy Park (HEP). HEP features the latest combined-cycle natural gas generating technology, producing up to 145 megawatts of power (http://p21decision.com/). In April 2015, ground was broken on the site and construction began. The remaining coal was used at the current coal fired plant (James de Young) in spring of 2016 and the plant came online spring 2017.
