Carboncounter.com is a website that lets users compare the lifecycle emissions and costs of new cars against other cars and against climate targets. I've recently updated it with new 2022/2023 model year electric vehicles.

A European version, developed in collaboration with myenergy Luxembourg, can be found at carboncounter.lu.

I built carboncounter.com using AngularJS and D3.js as an interactive version of figure 1 in our Environmental Science & Technology article.
