Sustainability Director Oliver Kroner says the city reduced emissions significantly between 2006 and 2015.
"We are able to demonstrate that city government has achieved a 36% reduction in carbon emissions, and city-wide we've been able to achieve an 18.4% reduction from all the emissions generated here," Kroner said.
Transportation, commercial buildings and industrial buildings account for nearly 85% of carbon emissions across the city.

Despite overall progress, industrial emissions increased during that time. Kroner says the industrial sector is especially difficult to manage.
"Each one is a unique organism — they have their own processes, they have their own facilities, and it's harder to design an umbrella approach to address all of them," Kroner said. "So we've met with industrial partners, and we've met with federal and state EPA to identify strategies, but it's hard to sum them up in a program."
