Spend enough time browsing carbon offset data and you’re bound to turn up something surprising. Join host Clark Merrefield with presenters Grayson Badgley and Maggie Koerth of CarbonPlan to learn the ins-and-outs of OffsetsDB, an open-access database of carbon offsets projects from around the world.

Carbon offsets are the cornerstone of a lot of climate policy — from corporate environmental responsibility plans to cap-and-trade programs to national net-zero goals.

But offsets are also financial instruments, with all the complicated bureaucracy and potential for malfeasance that come with any financial tool. Enter OffsetsDB, a repository of carbon offset projects and credits issued by five of the largest offset registries, produced by the nonprofit, nonpartisan CarbonPlan, which works to increase transparency around climate solutions.

In this webinar, hosted by The Journalist’s Resource, CarbonPlan research scientist Grayson Badgley and editorial lead Maggie Koerth will walk participants through:

  • What carbon offsets are and how offset markets work.
  • The difference between an offset, a credit and carbon capture.
  • Organizations that regulate the offsets industry.
  • How to compare important data about different types of offsets.

We’ll also set aside time for audience questions.
