Carbon emissions reduction where I live

I saw a guy yesterday outside the Xcel building on 18th in Denver holding a sign that said, “0 Carbon 2025”. Their plan is – 100% carbon free by 2050 and 80% less carbon by 2030. 

From their website:
“2017 We are leading the clean energy transition, and so far, have reduced carbon emissions 35% from 2005 levels”
