Recently usable-ish Offsetr does a depressingly effective job of calculating the carbon and mileage totals of your Dopplr travel network (Radar post). The larger your network and the more they travel the more impact they will have. Offsetr will tally and rank your network’s miles, carbon and offset price.
There are 164 travelers in my network and it has the dubious distinction of having the second-largest impact on the public score boards (that is sure to change with this post). My own impact is less than one percent of that and ranks significantly lower.
Offsetr comes from Will Carter. He’s the creator of MobZombies, the game where you run with an accelerometer to get away from virtual zombies (Radar post). Offsetr’s mileage data comes from the Dopplr API (which uses OAuth for easy access to users’ data). The carbon offset calculations (both the dollars and the pounds) come from terrapass, a carbon offset company.
I travel a lot for work. I’ve been using the RealCosts Firefox plugin so I can be aware of the impact of my plane tickets, but that doesn’t compare to seeing the cumulative effect of my travel. This is more meaningful. I would love to have Offsetr as a Greasemonkey script for Dopplr (or better yet as its own feature) for a constant reminder. How carbon friendly is your network?
