Mayors from 94 cities committed to cutting emissions from the sectors that most contribute to climate change (transportation, buildings, industry and waste) to keep global temperatures below the 1.5-degree Celsius goal of the Paris Agreement.

The big picture: The Global New Green Deal was announced today at the C40 Mayors Summit in Copenhagen. Despite the U.S. government pulling out of the Paris Climate Agreement, cities have committed to meeting greenhouse gas reduction goals.

"As mayors, our primary responsibility is to protect the lives and livelihoods of our citizens. Climate change now represents the greatest threat to their security, public health and prosperity," said Frank Jensen, lord mayor of Copenhagen, in a press conference.

  • He added that Copenhagen wants to be the first carbon-neutral capital city by 2025, and carbon emissions are down 40% since 2005.

What's next: Cutting global emissions in half by 2030 is necessary to void the worst impacts of the climate crisis, experts say. That means setting strict building codes, replacing fossil fuel energy sources with clean alternatives and dramatically reducing waste.

  • Los Angeles Mayor Eric Garcetti said we are entering a "make-or-break decade."
  • "Far from being in conflict, working on the ecology and economy go hand in hand. These two things are inextricably linked. In fact, we can build a more sustainable city at the same time we protect workers and create new careers," Garcetti said.

Trump pardons former fundraiser Elliott Broidy

President Trump has pardoned Elliott Broidy, a former top Republican fundraiser who pleaded guilty late last year to conspiring to violate foreign lobbying laws as part of a campaign to sway the administration on behalf of Chinese and Malaysian interests.

Why it matters: Broidy was a deputy finance chair for the Republican National Committee early in Trump’s presidency, and attempted to leverage his influence in the Trump administration on behalf of his clients. The president's decision to pardon Broidy represents one last favor for a prominent political ally.

President Trump issued 73 pardons and commuted the sentences of 70 individuals, hours from leaving office early Wednesday, hours from leaving office.

Why it matters: It's a last-minute gift to some of the president's loyalists and an evident use of executive power with only hours left of his presidency. Axios reported in December that Trump planned to grant pardons to "every person who ever talked to me."

Trump pardons Bannon in final hours of presidency

President Trump issued an eleventh-hour pardon to his former chief strategist Steve Bannon on Tuesday night, sparing a longtime ally from a federal fraud prosecution over his alleged misappropriation of nonprofit funds.

Why it matters: Bannon was the most high-profile name on a White House list of what's expected to be dozens pardons and commutations, with hours remaining in Trump’s presidency. His pardon of the former Breitbart News chief came as Bannon faced criminal charges stemming from a scheme to privately finance a southern border wall.
