This class was chill, and Paulson is overall a pretty solid professor. The class has weekly quizzes on the readings, and they were pretty fair for the most part. Some of them asked really bogus or random questions, but if you do the readings you'll be fine. The bulk of your grade is based on a final group project in which you do a deep dive into an emergent technology/practice that will reduce carbon emissions. Sometimes the lectures could get a little boring, as it was offered in weekly three hour seminars, but she normally gave us project work time which was nice. Overall I would recommend this class if you're looking for a relatively chill UD to take!
