The leaders of more than 100 countries, which hold more than 85 percent of the world's forests, will sign the Glasgow Leaders' Declaration on Forest and Land Use at the 26th UN Climate Change Conference of the Parties (COP26) in Glasgow on Tuesday, according to the UK Prime Minister's office.

The United Kingdom's Prime Minister will host a COP26 Forests and Land Use event at the COP26 summit, which is being held from October 31 to November 12 to bring parties together to accelerate action toward the goals of the Paris Agreement and the UN Framework Convention on Climate Change.

“In the biggest step forward in protecting the world's forests in a generation, more than 100 leaders will commit to halt and reverse forest loss and land degradation by 2030 at an event convened by the Prime Minister at COP26 today. The pledge is backed by almost $19.2 billion in public and private funding,” the press release added.

According to the press release, halting and reversing deforestation is "one of the most important things the world can do to limit catastrophic global warming," adding that "23 percent of global emissions come from land-use activity, such as logging, deforestation, and farming."
