A new book ranks the top 100 solutions to climate change. The results are surprising.

A new book ranks the top 100 solutions to climate change. The results are surprising.
...Includes an interview with the author, Paul Hawken. Here's an excerpt:

"Also sitting atop the list, with an impact that dwarfs any single energy source: refrigerant management. (Don’t hear much about that, do you? Here’s a great Brad Plumer piece on it.)

Both reduced food waste and plant-rich diets, on their own, beat solar farms and rooftop solar combined.

(Important note: The above comparisons are true in Drawdown’s central, “probable” scenario. There are also more ambitious scenarios, in which each solution is pushed to its full potential. In the “optimum” scenario, onshore wind rises to crush all competitors, reducing 139 GT. All scenarios use only existing, commercialized technologies, so they should be considered conservative. All the solutions, data, and references are available at drawdown.org.)"
