The University of Iowa met most sustainability goals it set a decade ago, but failed in a key area — garbage going to landfills. The University of Iowa released a report this spring on its progress towards its 2020 sustainability goals. Based on the original goals, the school met targets to:- Use less energy in 2020 than it did in 2010.- Get at least 40% of campus energy from renewable sources.- Drop per capita emissions from university travel by at least 10%. UI failed to divert 60% of campus waste away from the landfill by recycling, reusing and composting. The 2019 rate sits at 39%.
