I would like more detail on the calculation for their emissions/km number. In California, they list 148g/km, but the Union of Concerned Scientists has the California electric grid at 93g/km. That's a significant difference, and I wonder if they're taking the production profile of the CA grid into account.

Why is the SUV icon of a truck rather than an SUV? Or is there more aimed towards non US where perhaps SUV means pickup truck?

I’m not aware of anyone that does that calls a truck an SUV. The opposite is quite common though, even in the USA - people call SUVs, vans, and buses “trucks” when they’re used for commercial purposes.

148 g/km seems to be the default number. I got that same number for two different routes that were entirely located within British Columbia and Alberta, respectively. The problem is that British Columbia has an electricity emissions intensity of about 30kg/MWh while Alberta's is about 600kg/MWh. Hence, this website does not use correct electricity emissions data.

Maybe you can partner with the folks over at https://www.electricitymap.org/ to improve the emissions data?

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.

The other thing is the difference between a metric and US ton is only 10%. So you don't lose any sense of scale if you confuse the two.

Personally I think it's trying to hard to be cool. I'm all for making a calculator look cool - but this presented the data in an unclear/unhelpful way. Would be better if it was simpler/clearer.

Agreed. On a standard 1080px tall monitor, that "Show results" button requires a scroll. I would make the 1,2,3 cards stack so you aren't wasting tons of screen real estate. Also showing the map at the location entry screen invites clicking on the map which doesn't seem supported.

Otherwise, a cool project! Hopefully it motivates someone to think about their travels and its impact on the environment.

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

I don't think it is ignorance, just colloquial terminology coming into play.

I am curious though, is the USA the only place that calls it 'gas'? I've lived and travelled through most places in Oceania, Asia and Europe and almost everywhere else it is called 'petrol' and places that serve it are called 'petrol stations'. To me 'gas' is an entirely separate product, viz LPG gas, which a lot of taxis etc. use at the moment.

Yes, indeed, in Eastern Europe we refer to LPG as gas, and petrol as, well, petrol :)
