Enpalo is an online calculator that lets you estimate the flight emissions of your next airplane jaunt—you choose an airline, enter your origin and destination, then sit back and light up a cigar while you laugh about how many baby polar bears you’re drowning.

Officially the calculator is part of a for-profit that lets you purchase carbon offset credits, but we remain skeptical of the idea that you can buy your way free from carbon emissions. What it could be useful for, though, is comparing different airlines to see which one comes in with the lowest score, and then factoring that into your next travel booking.
