The COP26 climate summit's first major deal will see 100 world leaders promise to end and reverse deforestation by 2030.
Brazil will be among the signatories when the deal is signed on Tuesday, a country where significant stretches of the rainforest have been cut down.
Following a failed deal in 2014 that promised to do a similar thing, experts have warned all commitments must be delivered on if deforestation is to be ended by 2030. The pledge also includes $19.2bn of public and private funds to help with the effort.
How will ending deforestation help with the climate crisis?
Forests absorb a large amount of CO2 that's released into the atmosphere, and with the felling of more and more trees, climate change could become irreversible.
UK Prime Minister Boris Johnson, who hosts the global meeting in Glasgow on Tuesday will call the deal a "landmark agreement to protect and restore the Earth's forests."
Some of the funding mentioned will be used to restore damaged land in developing countries, while some will also go towards the countries that have the most forestation. It is also said that 28 countries vowing to make the pledge will remove deforestation from the global trade of food.
Professor Simon Lewis, a climate change expert University College London, told the BBC the world "has been here before" in 2014 when deforestation wasn't slowed at all.
Ecologist Dr Nigel Sizer expressed disappointment in the target of 2030, stating that this is an emergency and "giving ourselves another 10 years to address this problem doesn't quite seem consistent with that."
