These free resources can help you quickly get up to speed on everything from the hot topics of COP28 to essential business sustainability skills. Most sustainability professionals have fully embraced the fact that our chosen professions commit us to lifelong learning. My personal training wish list includes at least a year of courses I’d like to take (someday!), and I know I’m not alone. Unfortunately, training can be expensive, time-consuming, or hard to find. The collection below represents the best courses, news, webinars, articles, and 101s I’ve discovered that take less than an hour of your time, are available on-demand, and are free. If you find yourself with a few precious moments of downtime this holiday season and would like to invest them in learning something new, you can finally learn how carbon markets work, learn the finer points of green claims regulations, understand TCFD scenario analysis, or even create your own decarbonization strategy. If all this free learning has you feeling like a workout, there are over 100 more sustainability courses in the next articles in this series. (Trish Kenlon)
