Gov. Maura Healey and Boston Mayor Michelle Wu traveled to Rome last week to present their plans for de-carbonization and climate resiliency at a multi-day summit hosted by the Vatican and the Pontifical Academy of Sciences.

The Wu administration aims to reduce the city’s carbon footprint via a suite of initiatives, including new rules on Boston buildings, which are responsible for over 70% of the city’s greenhouse gas emissions. Wu's goal is for city buildings, old and new, to be carbon-neutral by 2050.

Meanwhile, Gov. Healey is pushing her own climate reforms in the state legislature.

For more on their trip to Italy, Darryl C. Murphy speaks with Boston Globe politics reporter Samantha J. Gross, who traveled with Wu and Healey last week.
