More than 100 countries, accounting for 85% of the world’s forests, agree to protect and restore them

GLASGOW—World leaders from more than 100 countries, including the U.S., China and Brazil, agreed to a deal aimed at ending and then reversing deforestation by 2030, committing nearly $20 billion of public and private funds to protect and restore forests.

U.K. Prime Minister Boris Johnson, during the COP26 climate summit in Scotland on Tuesday, called the pledge a landmark agreement that includes countries accounting for 85% of the world’s forest land. But details about how such a deal, which isn’t legally binding, would be executed and policed haven’t yet been worked out.
