The protests — urging a faster shift to cleaner fuels to fight climate change — followed a two-day strategy summit that included work on a proposed Colorado ban on hydraulic fracturing, the technique used to extract oil and gas.
"The goal is to transition as quickly as possible to renewable energy so that all these communities affected by dirty fossil fuels can be healthier and not have to deal with that in their backyard," said Lauren Pagel, policy director for Earthworks, a Washington D.C.-based group that helped organize the summit.
"Oil and gas cause climate problems and cause pollution. They are, hopefully, the energy of the past," Pagel said.
The activists targeted Saddle Butte Pipeline, the EPA, Halliburton, the Colorado Oil and Gas Conservation Commission and Gov. John Hickenlooper's mansion. They set up a 20-foot mock drilling rig. Three activists were ticketed for blocking traffic at the mansion.
