Right now, could you prepare a slice of toast with zero embodied carbon emissions?
Since at least the 2000s, big polluters have tried to frame carbon emissions as an issue to be solved through the purchasing choices of individual consumers.
Solving climate change, we've been told, is not a matter of public policy or infrastructure. Instead, it's about convincing individual consumers to reduce their "carbon footprint" (a term coined by BP: https://amp.theguardian.com/commentisfree/2021/aug/23/big-oil-coined-carbon-footprints-to-blame-us-for-their-greed-keep-them-on-the-hook).
Yet, right now, millions of people couldn't prepare a slice of toast without causing carbon emissions, even if they wanted to.
In many low-density single-use-zoned suburbs, the only realistic option for getting to the store to get a loaf of bread is to drive. The power coming out of the mains includes energy from coal or gas.
But.
Even if they invested in solar panels, and an inverter, and a battery system, and only used an electric toaster, and baked the loaf themselves in an electric oven, and walked/cycled/drove an EV to the store to get flour and yeast, there are still embodied carbon emissions in that loaf of bread.
Just think about the diesel powered trucks used to transport the grains and packaging to the flour factory, the energy used to power the milling equipment, and the diesel fuel used to transport that flour to the store.
Basically, unless you go completely off grid and grow your own organic wheat, your zero emissions toast just ain't happening.
And that's for the most basic of food products!
Unless we get the infrastructure in place to move to a 100% renewables and storage grid, and use it to power fully electric freight rail and zero emissions passenger transport, pretty much all of our decarbonisation efforts are non-starters.
This is fundamentally an infrastructure and public policy problem, not a problem of individual consumer choice.

That's the thing though: in a green growth scenario it is not enough for a solution to merely *exist*. It must also be cheaper and being able to be deployed worldwide very fast and without hindering economic growth in the process. If any of these conditions are not met, either emissions will keep going up or growth will stop.

I appreciate all the references.
They all count externalities though. The producers (and most consumers) don't pay for externalities in our current economic system. That's not the world we live in.
So unless you're suggesting to overthrow #capitalism I don't understand how that argument helps the point you are trying to make.
@jgkoomey @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green
Economic growth is predicated on exploitation and ignoring externalities.
The biggest of which is obviously depletion of non-renewable natural resources, which includes not only fossil fuels, but also copper, aluminum, chromium, nickel, cobalt, etc.
@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green Dude, you’re just trolling at this point. You can’t use the reality of the current system to argue that the system can’t be changed to operate differently. Internalize the externalities then change will happen quickly. I’ve explained what I think the logical flaws are in your statements, now it’s time to move on. Good day.
@jgkoomey @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green
OK, "dude".
You sure explained the logical flaws to me.
Thank you for the discussion.
@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green I would add that current measures of economic activity only imperfectly capture the externalities associated with pollution, so the GDP growth that you now see is partly the result of ignoring real costs of fossil pollution.
@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green And of course we’re seeing very rapid growth in renewable power generation + battery storage, doubling every 2-3 years, in part because it’s cheaper even in direct costs terms than alternatives. Because of learning effects, that cost advantage will only increase over time.
