People of faith, civil society groups and communities impacted by climate change marched together in Rome today to express gratitude to Pope Francis for the release of his encyclical on the environment, Laudato Si’, and call for bolder climate action by world leaders.

Under the banner of “One Earth One Family,” the march brought together Catholics and other Christians, followers of non-Christian faiths, environmentalists and people of goodwill. The march ended in St. Peter’s Square in time for the Pope’s weekly Angelus.

The celebratory march was animated by a musical band, a climate choir and colorful public artwork designed by artists from Italy and other countries, whose work played a major role in the People’s Climate March in New York City last September. Among the artwork was a 75-meter sign in the shape of a green leaf, with verses from Scripture which speak to God’s care for creation and for the poor.

“As we stand at this critical juncture in addressing the climate crisis we are particularly grateful to the Pope for releasing this encyclical as an awakening for the world to understand how climate change impacts people across all regions,” said Arianne Kassman, a climate activist from Papua New Guinea who was in attendance at the march to speak on the realities of climate change in her region of the Pacific.

“The truth of the matter is that all of humanity needs to stand united in addressing the crisis of our times. Climate change is an issue for everyone with a moral conscience,” she added.
