How Green Are Your Travels?

This website offers a rough gauge of the carbon-dioxide emissions associated with flying around the country. Just plug in a starting point and destination and it gives you a round-trip estimate of the greenhouse-gas “footprint” of your travel. The goal is to encourage visitors to buy carbon-offsets to cover the greenhouse-gas cost of their treks. But you can play around for free, testing various travel scenarios. The game can’t help but open one’s eyes to the usually hidden cost of travel-related emissions. Other pages on the website allow you to calculate the carbon costs of travel by guests attending weddings, or even of home power consumption.
