About this Add-on
Whenever your browser lands on a search results page from a supported travel site (Kayak, Orbitz, etc.), Careplane is activated. The plugin scans your results page, extracts flight information, and submits these details to Brighter Planet CM1, a carbon calculation web service. When the calculations are complete, Careplane inserts them into your results page unobtrusively, allowing you to consider environmental impact as your compare your options.
Why should I care?
Because climate change is affecting all of us! We don't expect anybody to spend twice as much to take a green flight. But more often than not, going green is only $1 or so away—sometimes it's even cheaper. Careplane uses a sophisticated calculation methodology that considers more than a dozen factors, including aircraft type and projected passenger load. Bottom line: it's better to know than not, right?
