The biggest producers are and will always be the mass market stuff, though. Who cares if 1% of beef is produced carbon neutral? It's nice, but it makes no tangible difference. Sadly this method of encouraging better behaviour won't work unless a costco or a mcdonalds, for some insane reason, wants to cut their profit margin and buy more expensive beef.
The worst move the environmental movement did is let the environmentally sensitive product be associated with consumption by a rich liberal urban elite. Until someone can fix this and disassociate ecological efficiency from the limousine liberal, these programs are unfortunately going to only be marginal. Minimizing environmental externalities can't be seen as optional. Lots of reasonable things increase cost - such…

It's an interesting puzzle as to how you'd monitor something like that for a global warming tax. Random cow inspections? Some kind of satellite thing?
Add a default per-cow tax, and deduct from it for purchase of a seaweed feed, and make it bite sufficiently that it becomes substantially cheaper to include seaweed in the feed. This is how Norway encourages bottle recycling: There's no law mandating recycling of bottles, but there's a substantial tax on beverage containers that you get a reduction of in proportion to your return rate. This has resulted in a return r…

What were the conclusions of your research?
Not the OP, but the typical conclusion would be "effective altruism indicates I should stay in tech and give money to helping fisherman transition to seaweed farming." It's very hard to pass this analysis, since "high tech" is almost universally more valuable to humanity, per unit, that something low tech like farming. If you're already in tech and you want to "help the world", giving money is almost always the best…

Don't make assumptions. Life is meant to be enjoyed, and we work for a third of our lives. Perhaps some of us don't want to do the same work for our entire lives.
Lastly, tech isn't how I would give altruistically. I'd trade options and futures and donate the profits. The impact would be orders of magnitude higher than donating my hourly/salary wages.

#74I wonder if the seaweed influences the taste of milk or meat.

Carbon neutral is essentially shorthand for doesn't contribute to climate change . Methane (a) contains carbon and (b) is a much more potent greenhouse gas than CO2.
> More potent Only in the short term.
Methane has a GWP (Global Warming Potential or equivalent impact compared to same amount of carbon dioxide) of 86 over 20 years; 34 over 100 years; and 7.6 over 500 years.

Not that short-term. Methane has a GWP (Global Warming Potential or equivalent impact compared to same amount of carbon dioxide) of 86 over 20 years; 34 over 100 years; and 7.6 over 500 years. https://en.wikipedia.org/wiki/Global_warming_potential
34 / 5 is 6.8 so most of that 500 year potential is front loaded to the first 100 years. The difference from 7.6 vs 6.8 is because it breaks down into some CO2. And in fact is less potent than C02 from year 100-400.
Re: Scientist discovers particular seaweed nearly eliminates cow methane emissions
#79There probably isn't an incentive to reduce methane emissions for farmers right now though, right? We'd have to pass regulations mandating a reduction, or an emissions tax or something.
I think we will be able to detect methane emissions on a large scale from space sometime soon, e.g. [1]. At that point, farmers can't escape the law in any way, and they will have an incentive to reduce emissions.

US does the same actually. $.05 tax on all bottles, $0.05 payment for recycling. It used to get people to recycle but now the penalty is too small to be worth it. On the flip side, rooting through garbage cans for recycling deposits is now a viable source of income for urban poor.
