Earlier quoted context omitted.

Mine too (55mpg average Skoda octavia which being much like a Passat is in their 'luxury' category). I'm guessing they make assumptions about the mix of electricity on the grid. Seeing as we are able to purchase green electricity here they should let us alter that assumption.

Yes, your assumption is correct, we actually account for the means of electricity production, as well as the car production process emissions related to building a single electric vehicle. It's a great idea to be able to switch those overhead emission calculations if you wanted to, we'll get on that!

It's great you're taking these "external" variables into account. To bandwagon on the environmental costs of car production, it would be cool to see motorcycles added to the lineup. A lot of motorcycles are lax on emissions control so it would be very interesting to see how they compare to hybrids and electrics.

Hi there, We at BetaPeak ( https://betapeak.com ) are a small team of dedicated developers with passion for side projects and positive social change. We're located in Bulgaria, which currently has the worst air quality in all of Europe, so this led us to think - we sure as hell are not the only ones with that problem, there must be thousands of cities around the globe that breathe dirty air, we definitely need to rai…

Can't speak for all metric users, but I found "mt" for metric tonnes just confusing; the standard abbreviation is just "t".

Yes, that's easily confused with the imperial ton, but I think that's a less important problem.

For the units, do you mean US Customary or do you really mean Imperial? The gallons are very different. There is even a difference in miles if you want to be picky, with the US using statute miles in some states and international miles in other states. The international mile is 1.609344 km, and the statute mile is about 1.6093472 km. This isn't a huge difference.

Given that's a difference in the sixth significant figure, it's probably not even a rounding error for these calculations.

I was confused by the results then read online: "It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but the oxygen in the air."

btw, have O2 levels been dropping over last century? edit: https://weather.com/science/nature/news/earth-atmosphere-los...

Love it because my beloved Honda S2000 is one of the 4 examples under "sports car" :) Very neat project!

LOL, logged in at work just to make this same comment. You never know the love of a car until you've owned one.

They're amazing little cars. Mines 14 years old and I'm still hard pressed to find a car that makes me feel the same way while driving it. Was the first car I purchased entirely on my own (thanks, Dad!) and I can't imagine ever selling it.

Oddly my "mid-sized" car (eg, VW Golf) supposedly gets 18mpg, but I was driving the 300hp one and still getting 26+mpg :)

Then again, I just replaced it with an electric, so I guess I'm producing half the CO2. And am "100% solar" (for what that's worth), so... 0?

This is probably just me being ignorant, but I had to look up whether or not petrol was standard gasoline.
