The seaweed pellets they add to cows food that eliminated most of their emissions must be the most ingenious climate policy and breakthrough. Before these were invented we were looking at a situation where meat consumption (or at least beef) may have to be phased out. The rapid development of battery technology must be a close second. I remember as a kid in the 1990s it was difficult to get good rechargeable batterie…

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, microplastics, etc.)

The Asparagopsis supplements I think you are referring to are arguably clever, but

They haven't really changed the game, at least not yet. But assuming optimistically they can reduce cow methane emissions and downsides can be avoided [1], the magnitude of the reduction [2] probably will not make or break the continuation of the cattle industry.

Is the seaweed actually in use beyond some test farms or research herds?

Apparently it has been commercially available to cattle growers since 2022 but not sure on uptake https://www.future-feed.com/buy-asparagopsis

Did anyone get the short list in a clear format? That article was the most handwavy, avoid the point, whitepaper I've read in a long time.

Courtesy ChatGPT when asked to summarize the final paragraph before the discussion:

## Developed Countries

• Transport Sector:

• Pricing: Most successful individually (20%)

Subsidies: Highly effective when combined with pricing (33%).

• Electricity Sector:

     • Regulation: Most effective as a stand-alone policy (33%).

     • Pricing: A key component in successful policy mixes (50%).

    • Subsidies: Not effective as a stand-alone policy.

• Industry Sector:

• Pricing: Most effective when used alone (43%).

• Subsidies: Can be a valuable complement to other policies.

• Buildings Sector:

• Subsidies: Slightly dominant, effective both individually and in combinations.

• Variety of Instruments: Broad set of policies can be similarly effective.

## Developing Countries

• Transport Sector:

• Regulation: Most powerful as a stand-alone policy (33%) and in combination with subsidies, pricing, and information (33% each).

• Electricity Sector:

• Subsidies: Most powerful as a stand-alone policy (67%).

• Complementarities: No effective policy combinations detected.

• Industry Sector:

• Pricing: Shows the most synergy with other policies (50%).

• Subsidies: Effective complement in policy mixes.

• Buildings Sector:

• Regulation: Most effective as a stand-alone policy.

• Variety of Instruments: Broad set of policies can be effective, with a slight emphasis on regulation.

Too bad neither Europe nor the US seems capable of building reactors at reasonable cost. Even China which is building reactors the fastest is only projected to have nuclear account for single digit percentages of its electric consumption for decades.

Wasn’t there news not long ago that China has been building solar power (peak capacity) with an equivalent power of five nuclear power plants per week ? Even accounting for much lower cumulative output, this is far more than they have in the pipeline for nuclear power.

Most countries investing in nuclear do so in part to fund a domestic nuclear industry so that they can at least partly privatize the cost of a nuclear arms program. Nuclear is too expensive to be competitive without governmental support.

Let's have a look at France's emissions : https://ourworldindata.org/co2/country/france Somehow, from 1973 they went from 10t C02 per capita to 4.8 t per capita in 2022. Their GDP at the same went from 264 Bn to ~2779 Bn https://www.macrotrends.net/global-metrics/countries/FRA/fra... Whatever mysterious method of C02 reduction they used should be investigated.

Germany saved approximately the same 5t/year/capita since then. It went from 14t in the late seventies to about 8t today. Carbon/GDP is pretty much the same for both countries since the mid 90s.

China is building whatever energy sources it can. In amount it can. https://www.npr.org/2023/03/02/1160441919/china-is-building-...

These are the most important, by far, as they are existential threats:

1. Pandemic evolution

2. Antibiotic resistance

A distant third is GHGs / climate change, and then the other issues that matter only if we stay alive.
