Pittsburgh's Democratic Mayor Bill Peduto signed an executive order on Friday promising the city will continue to comply with the Paris Climate Agreement, joining at least 91 other cities defying President Trump's decision to withdraw the U.S. from the global climate commitment. Under the executive order, Pittsburgh will continue working toward clean energy climate objectives, including 100 percent renewable energy consumption for municipal operations by 2030. The Pittsburgh mayor on Thursday blasted the President's decision to abandon the Paris accord, stating "it will set us back decades." The steel city became the focal point of the opposition to Trump's climate decision after the president said he backed out of the Paris deal because it was unfair to the U.S. "I was elected to represent the citizens of Pittsburgh, not Paris," was his signature line from the speech. Peduto told the local Pittsburgh press he was "personally offended" by the Trump's speech.
