People were trying to understand the carbon output of their flights. Everybody knows how long they sit on that airplane, so we created a tool that's based on the number of hours. There's a calculation for short haul, medium haul, and long haul flights, and it not only calculates the carbon but it puts a price on it. And 100% of the time, consumers are shocked at how little it costs to actually offset their flights. So we have seen a rapid increase in people taking action using this tool.
