SHEFIK: nj, ale i to elekteoauto dobíjené uhlím má stále nižší provozní uhlikovou stopu, protože 2/3 energie v motoru nevyplitvas na topení. Jinak oze tomu samozřejmě dávají jiný rozměr. Problém ale je náročnost na výrobu, ta je o něco vyšší než u klasického spalováku, ale ne zas o tolik. Tady pak narážíme na to jak dlouho člověk auto provozuje, protože pokud budeš každý 3,4 roky kupovat nové tak tam je zase problém s náročnosti výroby u všech.
Na druhou stranu u nás je v průměru 14 lety vozový park, takže i kdyby se elektromobily rozmohli, bude trvat dalších cca 14 let než nám je naprodavaji Němci jako ojetiny.
V tomhle ohledu by měli mnohem větší význam elektokola, které se teď stávají populární na dojíždění do práce.

SHEFIK: kdyz jsem si delal resersi naposledy, tak tenhle typ rasy koupit nejde, my treba dokrmujem dobytek rasou kombu protoze je to dobrej sirokospektralni zdroj mikronutrientu, ale tenhle efekt asi ma nejakej jinej druh ras. nicmene je tu videt, ze v obou pripadech jde o management - jednak v otazce regenerace ekosystemu, tj. zda a jaci bylozravci jsou potrebni a nutni pro regeneraci suchozemskejch ekosystemu, a jednak jde (zde skrz tu specifickou rasu) o management mikrobialniho spolecenstvi toho bachoru.

SHEFIK: at neplacam slamu :) byl to seaweed..

In Australia, direct livestock emissions account for about 70% of greenhouse gas emissions by the agricultural sector and 11% of total national greenhouse gas emissions. This makes Australia’s livestock the third largest source of greenhouse gas emissions after the energy and transport sectors. Livestock are the dominant source of methane (CH4) and nitrous oxide (N2O), accounting for 56% and 73%, respectively, of Australia’s emissions.

...

Feeding one type of seaweed at 3% of the diet has resulted in up to 80% reduction in methane emissions from cattle.

YMLADRIS: jeste jsem to necet, ale pripomina mi to diskuzi s elektroautama - kdyz mas elektrinu z uhli, jak na vyrobu, tak provoz elektroauta, tak je jeho ekologictnost oproti dieselu diskutabilni. jakmile mas input cistsi (renewable/solar atd.), jses az na 30% emisi... vzdy jde o pouzitou techninku (metodicky postup) nebo technologii...

vic bych ale u dobytka koukal na metan - jenze ale i tam bude tam vic faktoru, nedavno sem nekde cetl ze nejaky specialni traviny u hoveziho redukujou tvorbu metanu v zazivacim ustroji o desitky procent. asi je nebudeme sejt na vsech pastvach po svete, ale je to dobrej highlight na zamysleni, ze lide se casto zameruji na konec problemu (dobytek/jist maso), ne na problem samotny (pricina tvorby metanu/co2)

nejaky dohnal za hovezi, nedokazu posoudit jak moc je to v poradku

Uhlíkovou stopu masa nepočítáme dobře. Ve skutečnosti je menší, než se udává - Ekolist.cz

To vše dohromady kilogramovou flákotou skutečně deklasuje. Jenže co když budete krávy pást na již dávno zřízené pastvině někde v podhůří moravských hor a nemuseli jste kvůli tomu klučit jihoamerický prales? Doberete se toho, že kilo hovězího masa váží rázem „jen“ 6 kilogramů emisního CO2. Což je oproti původní stovce dost zásadní rozdíl.

New Study Confirms Extensive Gas Leaks in the North Sea −
https://evobsession.com/new-study-confirms-extensive-gas-leaks-in-the-north-sea/amp/

We have combined investigations at additional wells with extensive seismic data. The results clearly show that thousands of tons of methane are leaking from old drill holes on the North Sea floor every year,’ says Dr. Christoph Böttner, who is the main author of the study, which is part of his doctoral thesis at GEOMAR.

...

The positions of the boreholes and the location and extent of the gas pockets indicate that this area of the North Sea alone has the potential to emit 900 to 3700 tonnes of methane every year

...

In seawater, methane is usually consumed by microbes. This can lead to local seawater acidification. In the North Sea, about half of the boreholes are at such shallow water depths that part of the emitted methane can escape into the atmosphere. Methane is the second most important greenhouse gas after carbon dioxide.

Ranking 41 US States Decoupling Emissions & GDP Growth −
https://evobsession.com/ranking-41-us-states-decoupling-emissions-gdp-growth/

Between 2005 and 2017, 41 U.S. states and the District of Columbia reduced their energy-related carbon dioxide emissions while increasing real gross domestic product, debunking the myth that economic growth can only occur by compromising the health of the planet.

...

A combination of technological, market and policy factors have allowed states to reduce their CO2 emissions. This includes a major shift from coal to natural gas in the power sector; the rapid deployment of wind and solar power in recent years; more stringent efficiency standards for vehicles, lighting and appliances; and the shift to a more service-based economy.

KEB: LINKOS: Presne, my mame hlavne problem s technokratickym oligarchickym kapitalismem nebo jak to nazvat, kde jakkakoliv aktivita se vytezuje primarne za financnim ziskem a nebere v uvahu environmentalni dopady. U kazdyho procesu, aktivity, sektoru, ale i pestovani plodiny jde o to, v jakym kontextu a jakym zpusobem s tim pracujes. Neda se rict, ze repka je spatna, ze paleni biomasy je spatny, stejne jako se to neda rict treba o palmovym oleji per se.
Zalezi vzdycky na co se pouziva, jake jsou alternativy, jakym zpusobem se produkuje, etc etc.
Z tohodle duvodu mi prijdou lehce naivni ruzny bojkoty produktu, protoze mi predevsim musime zmenit zpusob rizeni nasi ekonomicky aktivity, aby ty environmentalni dopady do sebe nejak zahrnovala, coz je ukol, kterej je ale podstatne narocnejsi...

LINKOS: osobně si myslím, že prohlášení dřevěné biomasy a její pálení za CO2 neutrální byl jeden z největších environmentálních zločinů moderní doby.

That point makes the “social cost of carbon” one of the most critically important metrics underlying regulation of climate pollutants. An estimate of the dollar costs of each ton of carbon pollution caused by climate change, the social cost of carbon guides federal agencies that are required to consider the costs and benefits of proposed regulations. Federal agencies so far have used the social cost of carbon while writing regulations with more than $1 trillion in economic benefits.
In 2010, a governmental interagency working group in the Obama administration established the first federal social cost of carbon estimate of $45 per ton of carbon dioxide pollution. In 2017, newly inaugurated President Donald Trump quickly disbanded the interagency group by executive order, and within months his EPA slashed the metric to between $1 and $6. The latest research by an independent team of scientists concludes that the social cost of carbon should actually start at about $100 to $200 per ton of carbon dioxide pollution in 2020, increasing to nearly $600 by 2100.
Should presumptive Democratic nominee Joe Biden win the presidency in the November election, his federal agency appointees will undoubtedly set about revising the social cost of carbon to reflect the up-to-date climate science and economics research. The revised social cost of carbon will in turn justify more stringent federal climate regulations. A Donald Trump second term would instead result in another four years of underestimated climate impact costs and continued delays in efforts to curb carbon pollution.

The UK’s biggest pension fund, the government-backed National Employment Savings Trust (Nest) scheme with nine million members, is to begin divesting from fossil fuels in what climate campaigners have hailed as a landmark move for the industry.
The fund will ban investments in any companies involved in coal mining, oil from tar sands and arctic drilling. But the move puts Nest – a public corporation of the Department for Work and Pensions – potentially at odds with the current pensions minister, Guy Opperman, who earlier this month condemned divestment as “counter productive”.
