The Institute for Transportation & Development Policy (ITDP) is a non-profit group that works all around the world -- everywhere from Jakarta to Rio de Janeiro -- to design and implement both transport solutions and policies that help to make our cities more livable, equitable, and sustainable. If you're interested in learning more about the kind of work that they do, you can download a copy of their latest annual report, here.
Most recently, the group published a report called, "The Compact City Scenario - Electrified." In it they argue that two things need to happen together if we are to move humanity toward net-zero carbon emissions and reduce global warming to less than 1.5 degrees Celsius by the end of the century. One, we need to fully electrify our transport (which I think is fairly obvious at this point). And two, we need a modal shift.
