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.

@ajsadauskas @green is it not worse than that?
There is more or less a 1:1 correlation between energy use and GDP.
We don’t have the time to build out the scale of renewable infrastructure that would replace our current energy use.
We need to use much less energy which means much smaller and therefore radically different economies

@urlyman @ajsadauskas @green Absolutely. I put it this way: we probably have enough in the way of consumer goods to last us the next 10 years. So let's stop buying new stuff - clothes, furnishings, tech gadgetry, hobby supplies, sports gear etc - for 10 years, while we wait for new technologies to get established and new infrastructure to be built. (Is 10 years enough to develop cargo-carrying airships?)
To manage the lack of employment, put the whole population on Universal Basic Income and limit working hours to 20 per week (with some obvious exceptions).
To enable repair of goods, outlaw practices like voiding warranties if repairs are made by someone other than the manufacturer. Provide incentives for people to set up small local repair businesses.

@jgkoomey @ajsadauskas @green As with your other reply, I defer to your scholarship and understanding but unfortunately I don’t have an Elsevier subscription.
I’m aware of many scholars whose analysis suggests really significant decoupling is at best extremely doubtful. I guess we’ll know in years to come who was right.
From my layperson’s perspective the immovable constraint would appear once again to be time…
@jgkoomey @ajsadauskas @green e.g. in this much shared tweet from last year, Ireland is the decoupling poster child but its rate of consumption-based emissions reduction over the 14 years was around 3.6% per year and 2 of those years were the global financial crisis.
It sure looks like decoupling is running at a rate decades too late so maybe we should be pulling other levers?
@urlyman @jgkoomey @ajsadauskas @green
Unfortunately Ireland's economic statistics are a bit misleading. It's not all actual stuff happening in Ireland, but some big corporates having EU or EMEA HQs in Ireland. Possibly Microsoft, PayPal, Apple etc.
@jgkoomey @urlyman @ajsadauskas @green
GDP is a garbage metric. It encourages destruction and externalization.
@jgkoomey @ajsadauskas @green Thank you for taking the time to point to further nuance and reading. I’ll endeavour to dive in.
Like you, I hope we buck our ideas up. Fast
@urlyman @jgkoomey @ajsadauskas @green
Do any of these decoupling claims hold when looking at the global economic system as a whole?
While these statistics claim that they account for trade it is a very theoretical number. Would the emissions be the same if Ireland had to produce everything it imports locally? Just imagine that. Of course they would be much higher.
@urlyman @jgkoomey @ajsadauskas @green
The uncomfortable truth is that national accounting like that can make western countries feel good about themselves, but all it does is put colonial relations on display.
The two sobering graphs worth looking at are humanity's material footprint: https://unstats.un.org/sdgs/report/2019/goal-12/ and global emissions: https://ourworldindata.org/grapher/total-ghg-emissions?tab=chart&stackMode=relative&time=2000..2021&country=~OWID_WRL
All lines go up.
