I put a lot of thought into managing my personal carbon footprint, but there is always room for improvement. I do quite a good job with household energy. We live in a really small place covered by a huge mulberry tree so no cooling in the summer.

I need to do a better job with diet and air travel. Traveling has always been so important to me, but that means I've been racking up quite a high air travel carbon debt. I hope developing these carbon footprint calculators somehow lowers my net contribution to climate change. Does that count?
