"Climate is changing faster than our efforts to address it", said Obama, who noted that his administration's effort to deal with the issue "wasn't because of some ideological notions about the environment".
"We stand shoulder to shoulder with all of the USA cities and mayors that are committed to the Paris agreement", said Vancouver Mayor Gregor Robertson, who added that President Trump should listen to the mayors on the issue of climate change.
Trump announced earlier this year that the US would pull out of the Paris accord, which involves nations setting benchmarks to reduce emissions of heat-trapping gases. They also agreed to meet goals similar to those in the Paris climate accord, which President Trump announced earlier this year the USA would withdraw from.
The Forum will precede the One Planet Summit organized by the United Nations and the World Bank, at the initiative of the French government, which will take place on the 12 and be attended by several world leaders.
The Chicago Climate Charter, signed Tuesday, commits cities to carbon emissions reductions in line with the Paris accords. Mancera says the city is trying to accelerate a transition to soot-free engines and procure zero-emissions buses by 2025 with an overall zero-emissions goal for most of the city by 2030. The mayor didn't say how, exactly, that will be achieved, reports JDM.
Emanuel says the participating mayors are filling a leadership void created by Trump by signing a first-of-it's-kind worldwide charter agreement aligned to the Paris climate agreement that commits their cities to reducing greenhouse gas emissions that cause global warming and outlines specific plans for meeting the carbon emission reduction targets by 2025.

Cities from across the US -including New York, Chicago, San Francisco, and Washington-have all said they will commit to lowering their carbon footprint and take action on their own without President Trump.
The Chicago Climate Charter itself commits mayors to reduce greenhouse gas emissions equal-to-or-more-than what's proposed in the Paris Agreement. It also calls for them to work with scientific and academic experts to find solutions.
Officials are billing the North American Climate Summit that began Monday as the first of its kind for the city.
Obama came to Chicago to support Emanuel again during the mayor's 2015 re-election campaign, and a clip from that event formed the basis of a TV commercial Emanuel ran in the days before the vote.
Mr. Emanuel, a Democrat, has emerged as a vocal, persistent check on Mr. Trump's powers, clashing with the administration on climate change, law enforcement and immigration. The pact also called for cities to publish quarterly emissions data; to consider climate change when building infrastructure; and to take an active role in advocating climate-friendly policies.
Former U.S. President Barack Obama addressed the conference yesterday. "Western cities across North American are dealing with longer and harsher wild fire seasons". "This is my hometown, so I hope Rahm has been as good of a host as he was a chief of staff, and as good as he has been a mayor", Obama said.
Chicago officials said the idea is to fill the void left by the actions of Trump, who has worked to reverse much of Obama's approach to foreign policy.
