IOWA CITY — The Iowa City Community School District this year could see a 48 percent reduction of greenhouse gas emissions since 2018, putting it years ahead of a goal of a 45 percent reduction by 2030. By 2024, the district’s total emissions are estimated to be 6,346 metric tons of CO2, a 62 percent reduction from 2018, according to a report from Design Engineers of Cedar Rapids presented Tuesday to the Iowa City school board.“I’m very happy to tell you that we will have reduced our carbon footprint by 48 percent at the end of this year, nine years ahead of schedule,” said Duane VanHermert, the Iowa City district’s director of facilities.From 2024 and beyond, only small improvements from year to year are projected if no further reduction strategies are put in place, according to the report.
