In this episode Liz explores five practical rules for a truly sustainable household: 1. Buy less – only what fits the life you live. 2. Choose better – select durable, repairable materials (steel…
Today, I'll give you all five with the reasoning and the failures and then ask you to run just one.
Let me start with what the word means, because if we're going to use it as a rule and not a label, it has to mean something specific.
Sustainable means a system that can run indefinitely without depleting what it runs on.
That's the whole definition, and it's a definition about time, not about being green, not about being good, but about whether the thing you're doing can keep being done.
A farm that sells its topsoil is not sustainable however organic it is.
A business that costs its owner her health is not sustainable however much it earns.
And a household, this is the part that matters here, a household runs on four things: money, materials, energy, and attention.
Sustainable for a house means that none of those four is being drawn down faster than it comes back.
Not the money spent faster than it's earned, not the materials bought, used briefly, and thrown away in a stream that never returns.
Not energy burned without thought, and not attention, the fourth one, the one nobody puts on the list, spent on managing a house full of things that need managing until there's none left for the people in it.
And there are only three levers, which is a relief, because the shopping aisle would have you believe there are three hundred.
Reduce what comes in.
Extend the life of what you have.
Close the loops so that what leaves comes back as something useful rather than something gone.
Every one of the five rules is one of those three levers applied to a part of the house.
If you remember nothing else, remember the levers, less in, longer life, closed loops.
A household that pulls all three is sustainable whatever it's made of, and a household that pulls none of them is not however many of its objects were sold as such.
