Academy Award-winning actor Leonardo DiCaprio called on world leaders assembled at the United Nations on Friday to go beyond their commitments under the Paris Agreement on climate change, and push for “bold, unprecedented action.”

Representatives from more than 170 countries met on Earth Day to sign the Paris Agreement, setting a record for the most signatories to any international agreement in history on the first day it was open for signature.

“Yes, we have achieved this agreement,” DiCaprio said of the Paris Agreement, which for the first time, commits industrialized and developing nations to cutting emissions of greenhouse gases.
