U.N. Secretary-General Ban Ki-moon has invited heads of state and other leaders to the Sept. 23 summit in New York. The U.N. says the goal is to spur governments, industry and civil groups to make new commitments to addressing climate change.
The summit comes one year before world leaders will gather in Paris for global climate talks aimed at securing a deal to reduce greenhouse gas emissions. Obama has set a goal to cut U.S. emissions 17 percent by 2020, compared to 2005 levels.
Obama's trip will coincide with the U.N. General Assembly meetings and a Clinton Global Initiative annual meeting. Obama traditionally speaks at both events. The White House announced the trip Friday.
