Version 0.10 online

I'm very pleased to announce the general release of air travel functionality. You can now calculate your climate impact from air travel and see it alongside your domestic emissions. I predict you will be surprised...

It's a real relief to have it out there! I've had air travel working for a while now for the testers, but the graphs have been a real problem, because flight emissions are literally off the charts compared to the rest. However, by changing over to amCharts, the problem is solved. Your charts are also now much more interactive and fun to play with.

This is version 0.10, and it's the last one before the full 1.0 release (at least on my list). The next release will mainly be for tidying up loose ends that have been hanging around, and fixing any major bugs that turn up.

Let me know what you think of it!

Flight figures updated

Testers take note: I've just made some changes to the figures used for flight calculations, so some of you may find that your carbon footprints have leapt up a bit (mine has)!

I was originally using DEFRA figures for aviation emissions, but they do not take into account the extra effect of releasing greenhouse gases at high altitude, which is estimated to be around 2.7 times higher! I've found some better figures, so hopefully the new numbers will reflect better the actual climate impact of flying. I've also added the ability to select your class of seat. First class seats take up around 3 times the room of an economy seat, so if you choose to fly this way, your emissions will be 3 times as high!

I'm trying out a new graphing engine this afternoon, and if it works, then hopefully I'll be able to release flights across the entire site later on today!
