Drawdown's Top 10 To Drop Down Greenhouse Gases

I've recently been reading the book "Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming," edited by Paul Hawken. The book details Project Drawdown and it's ambitious plan to bring together 200+ scientists and researchers around the globe to analyze and rank 100 solutions to reverse the effects of climate change and global warming. Additionally, with the efforts to do this by 2050. In the book they detail what each option would look like by ranking based on the number of gigatons reduces of carbon dioxide, the economic net cost, and the economic net savings.

The term "drawdown" (as stated in the book & their website) "is that point in time at which greenhouse gases peak and begin to decline on a year-to-year basis"(page x in the Forward). They have broken their solutions into the following categories: Energy, Food, Women and Girls, Buildings & Cities, Land Use, Transport, and Materials... and they also share 20 "Coming Attractions" of innovative ideas on the horizon that have environmental potential.

The top 10 alone are fascinating, and speak once again to the fact that innovation is the key to solving our environmental issues:
  1. Refrigeration Management (HFC's & previous ozone depleters)
  2. Wind Turbines (Onshore)
  3. Reduced Food Waste
  4. Plant Rich Diet
  5. Tropical Forest Restoration & Recovery
  6. Educating Girls
  7. Family Planning
  8. Solar Farms
  9. Silvopasture (cattle in treed, not cleared, pastures)
  10. Rooftop Solar
Here's a video of Paul Hawken discussing Project Drawdown with Bill Maher. (It is Bill Maher, so this is mostly PG-13, except for about 6:30 and 7:50 in. Therefore, the information here is more for the adults in the room.)

To learn more about Project Drawdown, check out their website, especially their Frequently Asked Questions page. Also online (or in the book), you can see the entire listing by rank.
