The top 10 best solutions to global warming?

top solution solution_refrigerantmanagement

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.

Pat’s notes:

  • 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.

Helping Farmers Establish Roots in Local Schools and Institutions

The UVM Food Feed aims to spread the information about what it takes to support sustainable food systems. One key message to get out is the basic economics of farming. Here’s a recent example:

For farmers everywhere, there are a million things to worry about on any given day—weather, pests, soil, the sheer amount of work that needs to be done—to name only a few. However, for many farmers, added on top of this laundry list of tasks is finding a market to get the products they’re growing into the hands they have grown it for. “It’s easy to grow the stuff, the hard part is figuring out the outlet […],” says Molly Willard of Willow Brook Farm in Peacham.

Vertical farms: Growing more food where people live

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.

The Second Life Of Wind Turbine Blades

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.

Well done, Subaru!

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!
