Carbon Calculator Hits the Target
The Carbon Calculator Google Maps tool lets you draw polygons around an area on the map to obtain an estimate of how much the area is contributing to climate change migration. The tool uses several data layers; so it can provide information on each polygonal area's conservation values and forest status, as well as the amount of additional carbon that could be sequestered through forest restoration.
