The Forest Priority Index

Our data-driven approach to reforestation.

We plant trees in forests around the world. While every project is meaningful, we’ve identified five key regions to focus our reforestation efforts. To do this, we use the Forest Priority Index to prioritize areas in greatest need.

Think of the Forest Priority Index as a formula that shows where trees can have the most impact. This formula looks at many factors, including how the region’s reforestation will impact climate change, wildlife, and indigenous lands.

Not all our reforestation work takes place in areas identified by this index, but it helps us be as intentional as possible in planting the right trees in the right places.
