Project Drawdown

[rufuspollock]

Project Drawdown is a project to identifying solutions to get to "drawdown" (i.e. net zero or negative carbon emissions). Started in 2014 (by Paul Hawken and Amanda Ravenhill) they released a book in 2017 with their first summary of options and followed up with a major update in 2020.

The main output is set of potential "solutions" with detailed estimates of the impact - which allows for ranking solutions by their impact.

From the About page https://drawdown.org/about:

Founded in 2014, Project Drawdown® is a nonprofit organization that seeks to help the world reach “Drawdown”— the future point in time when levels of greenhouse gases in the atmosphere stop climbing and start to steadily decline.

Since the 2017 publication of the New York Times bestseller, Drawdown, the organization has emerged as a leading resource for information and insight about climate solutions. We continue to develop that resource by conducting rigorous review and assessment of climate solutions, creating compelling and human communication across mediums, and partnering with efforts to accelerate climate solutions globally.

Framework

See https://drawdown.org/drawdown-framework. Key summary info (in graphics):

Code

• They have their modelling framework (ported from excel to python) here: https://github.com/ProjectDrawdown/solutions

TODO

• Scrape the key solution info and store in a little database.
• Identify where the background calculations are coming from
