Carbon Removal Technologies and Risks

A four-week online deep-dive into the carbon dioxide removal (CDR) portfolio, covering advantages, challenges, and risks of currently pursued approaches to ensure CDR investments align with emissions reduction efforts.

The course starts October 3, 2024
Enrollment closes October 2

Live sessions: Thursdays from 8:00-9:30am PT

Course level: Introductory

About this course

This course delves into the essentials of Carbon Dioxide Removal (CDR), closely examining the portfolio of CDR solutions and dissecting the advantages, challenges, and risks associated with each approach. You’ll learn how to evaluate the potential of more than 20 CDR pathways, including biogenic solutions like afforestation, geochemical techniques such as enhanced rock weathering, and synthetic approaches like direct air capture and strategies for indirect ocean capture in different geographical contexts.


By the end of this course, you will understand the trade-offs between different CDR strategies and the most important principles to ensure that investment into CDR complements, rather than jeopardizes, emission reduction efforts.

Who is this program for?

Investors, founders, management consultants, sustainability managers, business analysts, engineers, marketing professionals, research scientists, policymakers, and more, who want to:
