AGGI
Annual Greenhouse Gas Index
The AGGI index provides a point of comparison for tracking annual changes in levels of atmospheric greenhouse gases.
ODGI
Ozone Depleting Gas Index
The ODGI is an index that relates changes in atmospheric amounts of ozone depleting gases and the recovery of the stratospheric ozone layer.
