Booked a rental car for an upcoming trip and looked through the options...
One of them that was listed was:
Greenhouse Gas Emissions Offset
The Optional Greenhouse Gas Emissions Offset is an optional environmental service chosen at the time of reservation that affords You the opportunity to offset the greenhouse gases emitted by a rental vehicle. This per-rental charge represents the estimated amount (as calculated by TerraPass Inc., a CO2 offset firm) necessary to offset the CO2 emissions produced by the average rental transaction and is not based upon Your specific Vehicle or miles driven. Funds collected from this charge are remitted to TerraPass Inc. See www.terrapass.com for more information.
Interesting.
