great work! I'm frankly coming around on this idea, being against it to realizing indirect benefits can actually make a large impact. One minor concern and question: Lot of times kilometers driven are shown to make sense of the footprint. Do you think this might make people think driving is not actually that bad. Hypothetical small product costs same as that long drive, let me just drive from my suburban home everyday. Maybe I'm taking it too far, but would be helpful to know your thoughts. And question would be how do you account for car emissions for this comparison. I've often noticed these calcs don't account for real-world fuel economies of cars or don't update methodology as EPA publishes better values. So please do share if you're considering to improve on that... thanks, best luck, and looking forward to how this product evolves.

Is this available for Safari? Thanks.

Out of curiosity, what database are you using for the calculations? I ask only because there seems to be a million of them out there. I'm sure they all have their faults but I would think users would want this level of transparency?
