What is the course

Carbon Offsets and Climate Change Mitigation

Carbon offsets are a popular climate change mitigation options, but they are also frequently criticized. This course delivers an in-depth understanding of the history and evolution of carbon offsets, the challenges posed by “commoditizing” emissions reductions and carbon removals as offsets, where offset markets are headed next, how they can be improved, and whether you should buy them.

Leverage Our Knowledge

The Climatographers, creators of the Climate Web, worked on the first carbon offset 35 years ago and have been involved with carbon offset markets ever since. They are widely regarded as experts on carbon offsets, the environmental integrity of carbon offsets, and scoring of carbon offsets. Take this course to leverage our decades of carbon offsets experience.


What Students Say

The course was excellent: well-organized, intelligent, clear, and informed by Dr. Trexler's years of experience. I highly recommend it.

charles wilson

Dr. Trexler‘s comprehensive knowledge allows him to simplify a fairly muddy discussion. This is a huge plus for viewers. This is clearly an educational course, not a partisan viewpoint. Well done!

jeffrey atkin

A comprehensive, well-structured, and clear course on carbon offsets. Surely a course to revisit, as it is packed with valuable information and charts. Don't miss it!

martina V.

This was a very insightful course. It is great to get first hand insights from Dr. Trexler and to learn more about Climate Web. The course covers a lot of key topics, the no-nonsense overview of Permanence, Leakage and Additionality in particular was very useful.

Personal Knowledge Management Using TheBrain Software

The Climate Web is built with a powerful personal knowledge management (PKM) software called TheBrain™. PKM is probably the most important skillset in today's world that you’ve never been exposed to in school or professionally. We all practice PKM at some level, but this course shows you how you can advance your personal and professional goals with personal knowledge management using TheBrain software.

Be Better Organized

Most of us are deluged by information that is relevant to us today, or might be relevant to us in the future. But we have no way of easily organizing and retaining that information, and usually quickly forget it. A “digital brain” can solve this problem. This course shows you a wide variety of ways that people are using TheBrain software to create fit-for-purpose “second brains," including the Climate Web and Your Climate Change Search Engine.


What Students Say

This course is an excellent intro to PKM (Personal Knowledge Management) with TheBrain software. I've been using the pro-version of TheBrain for many years, but there is one feature I missed, and that's using pre-set search terms. That alone made this course worthwhile for me (and was the reason for buying the course). Thanks, Mark, for pointing that out!

This course isn't (and doesn't pretend to be) a how-to on using The Brain software. Instead, it provides a good intro to the capabilities of The Brain and the various ways you can put it to use, within the broader context of knowledge management.

What Students Say

The application of predefined searches is a powerful technique that I haven't seen applied in other areas. The contribution of all this information by Mark Trexler, including the download of the Climate Search Engine for addition to my own TheBrain, is a tremendous contribution to the pursuit of saving mankind from mass climate afflictions.

The Climate Change Search Engine is a fantastic resource and a rabbit hole I have visited almost daily since taking your course.
