A concert calling for action on inequality and climate change was held in Paris on Thursday as world leaders attended the Summit for a New Global Financing Pact. Performers included Billie Eilish and Lenny Kravitz.

The "Power Our Planet: Live in Paris" event, which was organized by the nonprofit organization Global Citizen, included musical performances and speeches from climate activists and leaders from Brazil, Kenya, Barbados, and the World Bank, as well as well-known figures like Oscar winner Michelle Yeoh.

We are in such a critical period right now... On a stage in the Champ de Mars park near the Eiffel Tower in Paris, Eilish declared that "we really need to change our entire system so that the people most impacted by the climate crisis get what they need to fight it.

"I want us all to be part of the solution, not the problem," Kravitz said to the crowd during his performance.

About 40 leaders gathered to give a new global finance agenda momentum while the concert was going on.

The initiative aims to increase low-income states' access to crisis financing, reduce their debt loads, reform post-war financial systems, and free up money for climate change initiatives.

Earlier on Thursday, the World Bank announced that it would make financing for nations affected by natural disasters easier, and the International Monetary Fund announced that it had met its goal of providing $100 billion for weaker countries.

Along with speeches from actors Diane Kruger and Connie Britton, there were also musical performances by Jon Batiste and H.E.R.
