I am Hristiyan Dodov, Full-Stack Developer at Oblik Studio and developer of Mission Emission.
I wanted to clear a few things out and say my opinion about the project.
First of all, we're not chemists or scientists and we haven't worked with such either. We've done our best to do these calculations correctly, but there are just so many variables and giving more accurate results
demands more work, time, and information. Although the calculations are rough estimates, they are based on actual facts and research and are not some numbers we made up in our head. We would love to make things more accurate, but we need more support and data. Given that this is a non-profit project, it's a bit overwhelming.
For me, the goal of this project is to raise awareness about air pollution and make you think. Transportation plays a big role in air pollution, while it's an important part of everyone's life, making it easier for people to relate. We display an average estimate of emissions for your journey and then put the numbers in perspective with facts - for example, how much time is needed for a tree to absorb the generated CO2. The goal is to educate people as best as we can and perhaps even change their minds on transportation and make them think about using a greener transport. I don't think it matters how much exactly the air is getting polluted. The problem is that it's a lot, it's getting worse, and things doesn't seem to change. And that's our goal - to provoke a change.

Electric vehicle emissions:
Some people said that the app sometimes shows that electric vehicles produce more emissions than petrol/diesel vehicles. That's correct. Yes, the electricity itself doesn't directly generate emissions, but the way that electricity was created - probably does. Does it sound more eco-friendly to burn 40 kilos of coal to generate X amount of electricity and travel 10 kilometers, or burn 1 liter of petrol for that same distance? I made up those numbers in my head, but I think it illustrates my point nicely. Of course, this greatly varies with how each country or even city generates its electricity. That's also why it's so hard to provide accurate measurements and it's the reason we use average values. Basically, how green an electric car is depends on how the electricity it uses was generated.
Fuel consumption:
The vehicle category determines the fuel consumption value. It's not 100% accurate because it's based on averages from various kinds of car makes and models. We didn't focus much on that because you can change the fuel consumption on the results page and make it match that of your own vehicle exactly. That's also the reason why we didn't include the exact make and model, load, speed, etc. All of these things come down to fuel consumption, which is the most important part of emissions after all. Instead of putting a ton of settings, we simply put a vehicle category to give a rough estimate and then gave you the ability to change the fuel consumption however you wish.
