Mayor during the workshops will share his views on how Boston is working to fight human trafficking and climate change.

Hosts of the event the Pontifical Academy of Sciences, Pope Francis will also be a part of the event.

Mayor Walsh speaking to reporters at City Hall on Wednesday said that it is a great honor for him to be asked to represent the city about its efforts on the two major issues.

He added saying that he is not afraid of the huge gathering of the people rather he is afraid of Pope Francis who will also be present during the event.

According to a statement from the mayor's office, participants of the conference are expected to appeal to the United Nations that it must consider human trafficking as a crime against humanity and approve new sustainable development goals.

Walsh in Rome will also attend a reception with the US ambassador to the Vatican, Ken Hackett.
