After promising to stay true to the Paris Climate accords in the face of White House’s withdrawal from the agreement, Denver is drafting its own updated climate plan with some lofty goals.

One being a move to all clean, renewable energy by 2030 or requiring new buildings follow “net-zero” standards in an effort to meet the city’s goal of 80 percent carbon reduction by 2050. Lofty indeed. Denver has already made significant strides in emissions reduction, but it will have its work cut out for them.

Denver’s strategy for reaching that goal is detailed in a new study released Wednesday by the city’s Department of Environmental Health.

The study lays out Denver’s strategy to significantly reduce its carbon footprint including:

Denver could join other Colorado communities like Pueblo, Boulder and Aspen in making a formal commitment to 100 percent clean and renewable energy.

The city said it will open a 60-day public comment period to hear from residents on the study. It’s worth noting Denver has not formally adopted the study recommendations.
