The board approved a resolution Thursday night for the county to be carbon-neutral by the year 2050.
The county would become carbon neutral once it can remove the same amount of carbon dioxide it releases into the atmosphere through sustainability practices.
Director of Facilities Management Brent Sutherland thinks the goal is achievable and a worthwhile investment for the county.
He said over the last three years, the county has reduced its overall energy use, and he thinks more renewable energy will be in their future.
The Beloit City Council passed a similar resolution last month to set a goal of carbon neutrality by 2040.
