WRI believes that sound policies and informed decisions require the free flow of information. To that end, we commit to making our data and the results of our research freely available for all to use.
WRI strives to make our data and the results of our research open to anyone, enabling users to create their own products, conduct their own analyses, and draw their own conclusions. To support this vision, WRI commits to three key principles of open data:
Data should be licensed openly for free, allowing anyone to use, share, and adapt our work.
Data should be easily accessible and downloadable, thoroughly described, machine-readable, and maintained over time, to enable reuse.
Data should be complete and primary, such that others are able to test and examine our work.

| ความสอดคล้องเชิงตรรกะ |
"1. Due to variation in research methodology and/or date of content, tree cover, loss and gain cannot be compared against each other. Accordingly, “net” loss cannot be calculated by subtracting tree cover gain from tree cover loss, and current (or post-2000) tree cover extent cannot be determined by subtracting annual tree cover loss from year 2000 tree cover extent.
2. Please also note that “tree cover” does not equate to common definitions of “forest.” “Tree cover” refers to the biophysical presence of trees, which may be a part of natural forests or tree plantations. Thus, loss of tree cover may occur for many reasons, including deforestation, fire, and logging within the course of sustainable forestry operations. Similarly, tree cover gain may indicate the growth of trees within natural or managed forests.
