The University of Iowa on Thursday unveiled new sustainability goals for the next decade that — if accomplished — would cut its greenhouse gas emissions in half from a decade ago and transform the campus into a “living laboratory for sustainability education and exploration.”

But the goals fall short of what a collective of Iowa City “climate strikers” have demanded for more than a year — that the UI end coal burning immediately at its power plant, commit to using only renewable energy by 2030 and unite with the city of Iowa City in a “town-gown” climate accord.
