Tree Intercropping places #17 on Drawdown’s list of climate solutions. Intercropping on 571 million acres globally by 2050 would sequester 17.2 gigatons of carbon dioxide and, after a total investment of US$147 billion, save $22.1 billion over the 30-year span.

Supporting women smallholders ranks #62 on Drawdown’s list of climate solutions. It would reduce 2.06 gigatons of atmospheric carbon dioxide by 2050 and produce $US87.6 billion in net savings.

Restoration of Tropical Forests places #5 on the Drawdown list of climate solutions, with potential to cut atmospheric carbon dioxide by 61.23 gigatons by 2050.

Multistrata Agroforestry places #28 on the Drawdown list of climate solutions, with the potential to cut atmospheric carbon dioxide by 9.28 gigatons by 2050, with an up-front cost of $26.8 billion but net savings of $709.8 billion.

Drawdown lists Repopulating the Mammoth Steppe as a Coming Attraction—one of a collection of climate solutions that are not yet ready for widespread adoption, but should be able to contribute to global decarbonization by 2050. The solution hinges on reintroducing herds of migratory herbivores to the Arctic regions of the world, where vast stores of ...

Temperate forest restoration places #12 on Drawdown’s list of climate solutions. The research team estimates that by 2050, temperate forests will naturally grow by 235 million acres and could sequester 22.61 gigatons of carbon dioxide emissions.

Living buildings is one of the 20 carbon reduction options that Drawdown lists as Coming Attractions—strategies that weren’t ready for prime time when the book was published, but looked like promising approaches through mid-century.

Replacing soil-depleting annual food species with perennial crops is one of the 20 carbon reduction options that Drawdown lists as Coming Attractions—strategies that weren’t ready for prime time when the book was published, but looked like promising approaches through mid-century.

Building with wood is making a comeback, and is included in Drawdown’s list of “coming attractions” as a decarbonization option that hasn’t yet hit the mainstream, but could be a part of a wider set of post-carbon solutions by 2050.

Intensive silvopasture is one of the 20 carbon reduction options that Drawdown lists as Coming Attractions—strategies that weren’t ready for prime time when the book was published, but looked like promising approaches through mid-century.

Regenerative Agriculture places #11 on the Drawdown list of climate solutions, with the potential to cut atmospheric carbon dioxide by 23.15 gigatons. It carries an up-front cost of US$57.2 billion, but promises savings of $1.93 trillion, by 2050.

Nutrient management ranks #65 on Drawdown’s list of climate solutions, with potential to eliminate 1.81 gigatons of carbon dioxide and save a total of US$102.3 billion by 2050.

Increased cultivation of perennial bioenergy crops ranks #51 on Drawdown’s list of climate solutions, with the potential to reduce atmospheric carbon dioxide by 3.33 gigatons by 2050 at a net cost of US$77.9 billion, but net savings of $542 billion.

Protection of Coastal Wetlands ranks #52 on Drawdown’s list of climate solutions. The strategy could reduce atmospheric carbon dioxide by 3.3 gigatons by 2050, as long as 75 million acres of these vital ecosystems (out of a total of 121 million world-wide) can be secured within the next 30 years.

Accelerating the production of biochar ranks #72 on Drawdown’s list of climate solutions, with the potential to reduce atmospheric carbon by 810 megatons by 2050.
