Nuclear power.

Can't be everything. Electrical power is like 20-35% or so of total power used in most countries. I just checked some statistics of the Umweltbundesamt, the German ~environment protection office. The electrical fraction is suprisingly low! Though it's supposed to increase because most renewable energy production is electric. My guess is nuclear energy, more efficient cars, better insulated houses, and less heavy indu…

You have the cause and effect backwards. German homes are electric heated at a rate of around 5%[1], French at around 30%[2] (page 7).

As electricity prices are lowered (e.g. by state investment in nuclear) various things that use fossil fuels will shift over to electric.

Emission is only one of many problems with animal agriculture. Others include: - Land use (over-grazing, deforestation for pastures and feed crops, most of crops grown are for farmed animals, etc.) - Water use - Inefficient feed -> food conversion - Nutrient runoff leading to eutrophication - Increasing risk of zoonotic diseases and antibiotic resistance - Bioaccumulation (of PFAS, pesticides, heavy metals, microplas…

It should be said that, whether these are really problems depends heavily on how animal agriculture is done. In many cases animals graze on marginal land that can’t be used to grow human food directly. In these cases the alternative ways to get the same protein production could imply cutting down land in other countries to grow protein rich crops for humans. Water use doesn’t have to be high. In the US it’s a product…

Just to make the implicit explicit: the current reality of meat production is feeding livestock with protein rich crops grown on cut down land in other countries. An alternative’s model scalability and economic viability has not been shown yet.

So the hope of such a thing existing in the future should probably not influence how you choose to nourished yourself today

> moving manufacturing overseas At least per the available data from 1990, France has lowered its consumption-based CO₂ emissions in absolute terms: * https://ourworldindata.org/grapher/consumption-co2-emissions... And given the population has also risen since 1990: * https://ourworldindata.org/grapher/population?time=1990..lat... even if total emissions had stayed the same, per capita numbers would have gone down.

Anything that starts with "no..xyz" is always bullshit IMO written for an audience of morons.

I wonder if "low carbon cattle" exists in the grocery stores. I'd actually pay a premium for this.

Thanks for that. However, I would agree with those against that labelling. "beef producers to market their meat as low-carbon. Producers who can prove that their cattle are raised in a way that emits 10 percent less greenhouse gases than an industry baseline"

10% is nothing.

Me as well. There is a lot of hype around 'regenerative' agriculture and livestock now as well, but one really needs to see detailed life cycle analyses to know the full footprint of a food choice
