Environmentalist and entrepreneur Paul Hawken has edited a book called Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming, which lists and ranks “the 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world”.
Jason Kottke reports that on the website for the book you can browse the solutions in a ranked list. Here are the 10 best solutions (with the total atmospheric reduction in CO2-equivalent emissions in gigatons in parentheses):
1. Refrigerant Management (89.74)
2. Wind Turbines, Onshore (84.60)
3. Reduced Food Waste (70.53)
4. Plant-Rich Diet (66.11)
5. Tropical Forests (61.23)
6. Educating Girls (59.60)
7. Family Planning (59.60)
8. Solar Farms (36.90)
9. Silvopasture (31.19)
10. Rooftop Solar (24.60)
Refrigerant management is about replacing hydro-fluorocarbon coolants with alternatives because HFCs have “1,000 to 9,000 times greater capacity to warm the atmosphere than carbon dioxide”. As a planet, we should be hitting those top 10 solutions hard, particularly when it comes to food. If you look at the top 30 items on the list, 40% of them are related to food.
- I have italicized 6 out of the top 10 solutions that to me seem most relevant for Vermont.
- If you drill down, there is a wealth of data for each solution, with source references, on the Drawdown website. Well worth spending some time there.
Vertical farming. It just makes sense to me.

The world’s population is expected to reach 9.7 billion by 2050, 33% more people than are on the planet today, according to projections from the United Nations. About two-thirds of them are expected to live in cities, continuing a migration that has been under way around the world for years.
That’s a lot of mouths to feed, particularly in urban areas. Getting food to people who live far from farms—sometimes hundreds or thousands of miles away—is costly and strains natural resources. And heavy rains, droughts and other extreme weather events can threaten supplies.
That’s how Betsy McKay of the Wall Street Journal summarized the case for urban commercial farms.
While there are questions about the business model and sustainability of early pioneers in the niche, to my mind, there is no question we simply must figure out a way to make the numbers work.
In addition to the food-energy-dollar factors, I’m hoping someone explores the opportunities for education and workforce development as well.
Vertical “factory farms” in warehouses may not have the visual appeal of Vermont’s rural working landscape, but from my albeit limited experience, the kale tastes just as good.

Interesting look at a recycling problem I’d never considered: what to do with the huge blades of commercial wind turbines. Not too surprisingly, Denmark is leading the search for practical solutions, for example the playgrounds pictured in this post. ~ Pat
Turbine blades are made from glass or carbon-fiber composites. These materials are strong, lightweight and have a significant aerodynamic advantage, but they are nearly impossible to recycle. And they’re massive.

There aren’t many so-called cause, social good, or CSR (corporate social responsibility) campaigns that suit my standards. Most such campaigns don’t pass a basic sniff test for corporate greenwash. But to coincide with the seasonal opening of the National Park system over Memorial Day weekend, Subaru launched a new integrated campaign and microsite, Zero Landfill, that’s a winner by any standard.
Why it’s good
Not to minimize the impact of the stunning images and production quality, here’s why the campaign works:
- The history timeline demonstrates Subaru’s commitment to environmental responsibility through product stewardship, recycling, and zero waste — starting in 1989. (Bonus points because the timeline uses years and months in rings to echo the growth rings of a tree.) This classic “show, don’t tell” creative approach to demonstrate sustained commitment is the opposite of the common “cause of the year” bandwagons many companies jump on.
- The integrated, multi-channel campaign engages you wherever you may be at the moment. So far I’ve bumped into the #DontFeedTheLandfills creative via TV advertising, tweets (including video), Facebook post, Pinterest pins, and Instagram.
- Clicking the bright green “How can I help?” button in the lower left takes you to simple steps anyone can take to translate new-found awareness into actions that can make a difference for the National Parks.
- There are no annoying pop-up windows, floating social icons, or overwhelming array of choices.”Get Involved” offers three options: updates via email, Twitter, and Facebook.
I may return to the #ZeroLandfill campaign as it evolves, but meanwhile, kudos for the campaign launch Subaru!
I have come to value re:Work with Google as a solid source for new ways of thinking about “the future of work, people analytics, and how we can all make work better.” Check out this speaker’s video, The power of gender parity, (James Manyika, McKinsey & Company), from re:Work’s latest annual event.
If, as many believe, business is all about money, then the additional trillions of dollars projected for an improvement in the McKinsey Gender Parity Index data should cinch the business case for change.
I nearly missed this. You know how it is. In today’s stimulus-saturated world, I set limits for my daily news scans and then unplug each weekend for 24 hours. So as I approached the unplug deadline after an early morning hour of visual overload (and depressing news), another video didn’t really appeal. But it was from a trusted source in my Google+ circles (thank you, Johnathan Chung) so with my left hand on the ‘power down’ button, my right hand clicked play. Wow!
A Big Idea
“The idea does sound crazy, even for Google—so much so that the company has dubbed it Project Loon. But if all works according to the company’s grand vision, hundreds, even thousands, of high-pressure balloons circling the earth could provide Internet to a significant chunk of the world’s 5 billion unconnected souls, enriching their lives with vital news, precious educational materials, lifesaving health information, and images of grumpy cats.”
In an exclusive, Wired magazine goes on to add fascinating details, animations and clips as it tells the story of the initial tests in New Zealand. Just as I was beginning to focus too much on the prevalence of grumpy cats, a breathtaking reminder arrives of the global promise of Internet access.
Next Up: Digital Literacy?
While Google, and hopefully others, work on bringing balloon Internet access to remote areas, digital literacy is looming as a pressing, parallel need. From a local story on Middle-schoolers share technology with seniors, to the national news on the state of broadband access in the U.S., come recent reminders of how many people have been left out.
