The group, led by Governor Jerry Brown of California and Mr Michael Bloomberg, a former NY mayor, plans to work with outside experts to measure the effects of their pledges, and to announce an early tally at a United Nations climate conference this year. Last week, the U.S. Conference of Mayors, which includes both Republican and Democratic mayors, adopted a series of resolutions that are far more assertive than federal climate policy, including a pledge supporting cities' adoption of 100 percent renewable energy by 2035.
"As you prepare to celebrate Bastille Day and the US World War I Centennial with President Emmanuel Macron, we write to remind you of how significant the Paris Climate Agreement is to our country and the world and to urge you to strongly reconsider and reverse your decision to withdraw from the accord", ten Senators who represented the US at the 21st Conference of Parties in 2015, said in a letter sent to Trump Thursday.
"Reducing emissions is good for the economy and good for public health", Bloomberg said in a statement. Brown warned of a California ravaged by forest fires, disease and mass migration if lawmakers fail to renew the state's signature program to fight so-called climate change. In November, Brown and Bloomberg, along with other USA governors, mayors, and business leaders, will compile and showcase existing climate commitments of US subnational and non-state actors at COP23, to be hosted by the Government of Fiji in Bonn, Germany.
However, U.S. President Donald Trump announced in early June his decision to withdraw from the agreement.

"The American government may have pulled out of the Paris Agreement, but American society remains committed to it - and we will redouble our efforts to achieve its goals", said Bloomberg in a statement.
The United Nations' chief, António Guterres, said in a statement the plan to assess how USA cities, states and others are contributing to slashing global greenhouse gas emissions was "welcome".
The pledge will "provide a roadmap for increased climate ambition" over time, and offer a game plan to help organizations drive down their emissions. "We're already halfway there". Instead, the cities, states, and businesses - known in official United Nations parlance as "non-party stakeholders" - will join a registry known as the Non-State Actor Zone for Climate Action (NAZCA).
"Although the focus right now is on the states and cities in the United States following the announcement by the new administration, the fact is that this is part of a movement of sub-national governments around the world to contribute to the global climate agenda", Nuttall said. In 2016, Bloomberg Philanthropies distributed over half a billion dollars.
