Maine’s governor is in New York City to meet with European Union officials and others about strategies to deal with climate change.

Gov. Janet Mills, a Democrat, spoke during the United Nations’ Climate Action Summit 2019 on Monday. Her schedule on Tuesday includes meeting with EU officials and participating in a panel discussion with other governors about how the states will hold up America’s end of the 2016 Paris Agreement about climate.

Mills is also slated to deliver remarks before the premier of a documentary about shellfish growing and environmental stewardship.

Mills pledged on Monday that her state will go carbon neutral by 2045. She said in an executive order that the state’s climate council will give recommendations by Dec. 1, 2020, about how to meet that goal.
