"DrawDown" - GreenMoneyJournal.comApril 18, 2017 marked the publication of an ambitious new book with the audacious goal of showing how to reverse the warming of the planet through a myriad of innovations, many of them led by business for profit.

“Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming” (Penguin Books, Drawdown), was edited by the author and entrepreneur Paul Hawken along with a self-described “coalition” of research fellows, writers and advisors. (Full disclosure: I played a very small unpaid role in reviewing parts of the manuscript, and am included among the 120 or so advisors listed in the book. More details at www.drawdown.org/advisors)

The book contains 80 solutions — “techniques and practices” — that are ready today, and 20 additional “coming attractions” — innovations just over the horizon — that collectively can draw down atmospheric concentrations of greenhouse gases in order to solve, not just slow,climate change by avoiding emissions or sequestering carbon dioxide already in the atmosphere.

Hawken is quick to point out that the book’s seemingly brash subtitle is a bit tongue in cheek: this is the only “comprehensive plan ever proposed to reverse global warming,” he said. But the larger point is not lost. The book, along with an accompanying website (www.drawdown.org), may be the first to provide the insight and inspiration, backed by empirical research and data, that could enable companies, governments and citizens to attack the climate problem in a holistic and aggressive way. Moreover, many, if not most, of the solutions can be undertaken with little or no new laws or policy, and can be financed profitably by companies and capital markets.

At minimum, “Drawdown” is likely the most hopeful thing you’ll ever read about our ability to take on global warming.

Two and a half years ago, as the project got under way, I provided some context for Project Drawdown[1], the nonprofit created by Hawken to produce the book. While its roots date to the early 2000s, the project’s inspiration came in large measure from a 2012 Rolling Stone article by activist Bill McKibben, “Global Warming’s Terrifying New Math” — “three simple numbers that add up to global catastrophe,” as McKibben put it. His article offered a sobering arithmetical analysis underscoring “our almost-but-not-quite-finally hopeless” global predicament.[2] That article led Hawken to ask, “Why aren’t we doing the math on the solutions?” as he told me in 2014.

The new book aims to do just that: provide the metrics for the solutions needed to solve the climate crisis.

The 80 solutions that make up the bulk of the book are grouped into seven buckets: energy; food; women and girls; building and cities; land use; transport; and materials. To qualify for inclusion, a solution must have proven to reduce energy use through efficiency, material reduction or resource productivity; replace existing energy sources with renewable energy; or sequester carbon in soils, plants or kelp through regenerative farming, grazing, ocean and forest practices.

Each solution is ranked by cost-effectiveness, speed to implementation and societal benefit. Also included for each is its projected savings in greenhouse gas emissions by 2050, and the solution’s total financial cost — the amount of money needed to purchase, install and operate it over 30 years — and its net cost or benefit — how much money would be required to implement the solution compared to the cost of repeating business as usual.

“Drawdown’s” aggregate bottom line is shockingly affordable: When you total up the
net first costs and subtract the net operating costs for all 80 solutions, the net operating savings add up to $74 trillion over 30 years.

Cold Calculations

Consider refrigerant management, the book’s No. 1 solution. Hydrofluorocarbons, or HFCs — the chemicals used in refrigerators, supermarket cold cases and air conditioning systems — have up to 9,000 times greater greenhouse gas warming potential per molecule than carbon dioxide,depending on their exact chemical composition. Ironically, these chemicals were tapped in the 1990s to replace chlorofluorocarbons, which were found to deplete the planet’s protective ozone layer.

Last fall, a global deal was forged by nearly 200 countries to phase out HFCs by the late 2020s, but the chemicals will persist in kitchens and condensing unit for decades. Ninety percent of their climate emissions happen when fridges and AC units are disposed of at the end of their useful lives.[3]

On the other hand, creating refrigerant recovery “has immense mitigation potential,” said the “Drawdown” authors. After being carefully removed and stored, refrigerants can be purified for reuse or transformed into other chemicals that do not cause warming, they explain: “The latter process, formally called destruction, is the one way to reduce emissions definitively. It is costly and technical, but it needs to become standard practice.”

The book models the adoption of practices to avoid leaks from refrigerants and destroy them at end of life. Over 30 years, it calculates that 87 percent of refrigerants can be contained, avoiding emissions equivalent to 89.7 gigatons of carbon dioxide.

However, this is not one of the book’s more profitable activities. “Although some revenue can be generated from resale of recovered refrigerant gases, the costs to establish and operate recovery, destruction and leak avoidance outweigh the financial benefit — meaning that refrigerant management, as modeled, could incur a net cost of $903 billion by 2050.”

That’s a far cry from the No. 2 solution, onshore wind energy, not exactly a new technology, but one ripe for scaling; it already is cost-competitive with fossil-fuel energy in some areas, and continued cost reductions soon will make wind the least expensive source of installed electricity capacity.

“Drawdown” calculates that an increase in onshore wind from 2.9 percent of world electricity use to 21.6 percent could reduce emissions by 84.6 gigatons of carbon dioxide and create a net savings of $7.4 trillion from business as usual by 2050.

Adding offshore wind energy could save 14.1 more gigatons of greenhouse gases and generate $275 billion in additional net savings.

Falling Shibboleths

In the run-up to the book’s official launch, I recently asked Hawken how the solutions presented in “Drawdown” differ from what he and his team expected to find.

“We had our biases,” he admitted. “We all do. We had solar and wind right up there. We had ranked managed grazing very high from just reading the anecdotal literature. We didn’t have food as high as we found that to be. We had EVs much higher than they turned out tobe. We probably had pretty much the same list that most people come up with: solar; wind; don’t cut trees; don’t eat so much meat; and electric cars.”

“It may seem logical”, said Hawken, but it wasn’t to be. “The only one of those that made it to the top seven solutions was wind.” One solution never made it onto the final list at all: biofuels. “They don’t actually have any net contribution whatsoever, and that surprised us,” said Hawken. “It’s a shibboleth that fell for us.”

I asked Hawken to reflect on what had changed during the roughly three years between the project’s launch and the book’s publication.

“I think the big shift for us was on the economic side,” he said. “During that time, we might have crossed some threshold where the profit that could be made from the solutions now is greater than the profit being made from the problems.”

Regenerative agriculture is another area of significant progress. “You’re seeing some literally good-old-boy farmers from Saskatchewan right down through Texas and into White Oak farm in Georgia (www.whiteoakpastures.com) — thousands and thousands and thousands of acres. Their costs are going down. Their productivity is going up. Their vet bills are 10 percent of what they were. The yields have increased. The inputs have disappeared. These guys are buying more land from farmers who ruined their land and are going out of business. And they’re practicing regenerative agriculture in different and sundry ways.”

Women’s Work

Still another area that yielded surprises for the “Drawdown” team were solutions involving women and girls. As the book’s authors explain:

Due to existing inequalities, women and girls are disproportionately vulnerable to its impacts, from disease to natural disaster. At the same time, women and girls are pivotal to addressing global warming successfully — and to humanity’s overall resilience. As you will see here, suppression and marginalization along gender lines actually hurt everyone, while equity is good for all. These solutions show that enhancing the rights and well-being of women and girls could improve the future of life on this planet.

With world population mushrooming to a projected 9.7 billion by mid-century, food production will need to rise, said the authors, alongside reduced food waste and dietary shifts. Growing more food on the same amount of land cannot be done without attending to smallholders, many of whom are women, whose farming needs have been much overlooked.
