    Shell outlines steps to net-zero business by 2050; to cut production of traditional fuels 55% by 2030 - Green Car Congress
    https://www.greencarcongress.com/2021/02/20210216-shell.html

    To achieve net zero, Shell:

    Will continue with short-term targets that will drive down carbon emissions as it makes progress towards the 2050 target, linked to the remuneration of more than 16,500 staff. This includes a new set of targets to reduce net carbon intensity: 6-8% by 2023, 20% by 2030, 45% by 2035 and 100% by 2050, using a baseline of 2016;

    Expects that its total carbon emissions peaked in 2018 at 1.7 gigatonnes per annum;

    Confirms that its total oil production peaked in 2019;

    Will seek to have access to an additional 25 million tonnes a year of carbon, capture and storage (CCS) capacity by 2035. Currently, three key CCS projects of which Shell is a part, Quest in Canada (in operation), Northern Lights in Norway (sanctioned) and Porthos in The Netherlands (planned), will total around 4.5 million tonnes of capacity;

    Aims to use nature-based solutions (NBS), in line with the philosophy of avoid, reduce and only then mitigate, to offset emissions of around 120 million tonnes a year by 2030, with those used being of the highest independently verified quality;

    Will work with the Science Based Targets Initiative, Transition Pathway Initiative and others to develop standards for the industry and align with those standards;

    Starting at the 2021 AGM (annual general meeting), submit an Energy Transition Plan for an advisory vote to shareholders, the first in the sector to do so. The company will update that plan every three years and seek an advisory vote on the progress made each year.

    SEJDA: ty sodíkovky tam maj reflektor s80% odrazivostí, opravdu nevysvítí půlku energie zbytečně.


    TADEAS: v tomhle jsem zvědavej jak dopadnout polopoustni rozvojový země. Imho se akorát dostávají do chvíle, kdy by mohly zvládnout přechod pod kontrolovanou/skleníkovou produkci jídla ve velkým. Technologie k tomu jsou, chybí jen investice.

    TADEAS: jo no je zvlastni ze je kolem toho porad takova slepa skvrna / neznam jinej zdroj nez tebe kdo by to takhle mel propocitany

    myslim ze chybi nejakej fakt ozdrojovanej clanek s cislama na tema BYLOZRAVEC nebo tak neco

    plus teda mi vzdy kdyz o tom mluvis vrta hlavou, zda treba neni velkej rozdil v poctech tech krav. jako ze kolik krav by bylo optimalne potreba na co nejlepsi sekvestraci treba v CR a kolik jich zije ve velkochovech. Jestli to neni nasobne uplne jiny cislo, tj byste meli pravdu oba (tj slo by o to snizit pocet bylozravcu na zlomek, udrzujici pudu)

    YMLADRIS: porad se smesuje nekolik problemu dohromady. kdyz to vezmes planetarne, resime aspekt klimatu a aspekt ekosystemu. 'food' je subproblematika 'managementu ekosystemu' a 'logistiky'. pokud chceme skutecne delat management (planetarnich) ekosystemu, neni mozny ten subproblem "food" nadradit nad problematiku managementu ekosystemu. "food" lze z toho problemu managementu ekosystemu vymknout, napr. pokud budeme mit synteticky bilkoviny - pak nezijeme z ekosystemu, netransformujeme biomasu ekosystemu, ale stavime se jako bytosti na nejakou jinou, syntetickou platformu v nasi rezii. fine by me. problem managementu ekosystemu v takovem pripade zustava, odlehcem o cast nasich naroku na produkci bilkovin.

    jinymi slovy - resit food neni totez, co resit management ekosystemu. ruzne odpovedi na "food" muzou mit pro ekosystemy ruzne dusledky. reseni "food" je nutny kontextualizovat a podradit ty problematice (regenerativniho, klima stabilizujiciho) managementu ekosystemu.

    uhlik, stejne jako ostatni prvky se pohybuje v CYKLU, emise ekosystemu (zvirat, pud, lesu, mokradu...) jsou nevyhnutelny. emise ekosystemu nejsou fosilni emise. nas primarni problem jsou fosilni emise, ne ekosystemovy emise, ekosystemy vzdy budou mit nejaky baseline emise a skrze management si muzeme do omezeny miry vybrat, jaky budou. fosilni emise zastavit muzeme, ekosystemovy zastavit nemuzeme a nechceme, ekosystem cykluje a musi cyklovat (a my jeho cykly podporovat skrze nas management), predstava ze eliminujes bylozravce kvuli emisim je uchylny neporozumeni, ktery delaj lidi od kompu a jini lidi od kompu, kteri jim radej.

    hlediska ekosystemu neni o fokusu na emise (to je hledisko klimatu), z hlediska suchozemskyho ekosystemu je fokusem PUDA.

    pokud je fokus puda (a jeji sekvestracni schopnost), vyjde ze:

    - bylozravci jsou esencialni pro regeneraci pudy
    - soja (zaklad pro rostlinny "maso") pestovana takovym zpusobem, jakym se pestuje (orba, biocidy), je degradujici pro pudu (ekosystem)... a veprovy co si tu koupis je pravdepodobne vykrmeny na sojovejch smesich, jakozto nejlevnejsi (ale pro ekosystem degenerativni) bilkovine.

    takze za me pokud neco syntetickyho, tak synteticky veprovy; skot/bylozravci maj daleko daleko vetsi potencial pro regeneraci ekosystemu

    The rains this winter leave us a good supply of water in the catchment areas that will undoubtedly be of great help when the heat hits.

    SEJDA: dokázal bych si představit low tech verzi, kdy od úsvitu do soumraku je levnější, v noci dražší.

    A pak smart verzi propojené Smart domácnosti co spíná spotřebiče atd.

    KEB: u verejneho osvetleni to donuti zase obce prejit ze sodikovych vybojek s uhlem 160°, na ledky s uhlem 90°.
    A jinak souhlasim, dneska maji bezne dvou tarifove elektromery simku, stahuji si aktualizace. Takze asi neni zady problem prejit na X tarifu, jenom karapatek blbe, ze by pak museli udelat webove/moiblni rozranni pro odberatele, protoze ti by uz z display elektromeru nedokazali precit, kdy a za kolik spotrebovali kolik elektriny.

    LINKOS: taková věc jako levnější noční proud je vysloveně uhelný přežitek. Stačí udělat noční proud drahý a ono to všechny obchoďáky, výlohy billboardy atd donutí zhasnout s nemalým benefitem snížení světelného smogu.

    Veřejné osvětlení vypnout ti neprojde, ale předělat ho na diody by mohla být dobrá hladová zeď.

    A ještě tím padne argument, co dělat když nesvítí slunce. No a právě jsem se zacyklil, protože by to znamenalo mít vizi a přetlačit lobby protitlak.

    No a nynější politická jelita si aní není schopná vytáhnout hlavu z prdele natož takovýhle konstrukt.

    TADEAS: to prece nestojí v protikladu, to snizovaní spotreby “prumyslového” masa a zvysování spotreby volně pasoucího se. celkově by se spotreba měla snižovat a struktura promeňovat ve prospech ukladani co2 do pudy, zvyseni zamestnanosti (v zemedelstvi!?!) a kvality pudy.

    TADEAS: tak třeba zákon ze od určité zastavěné plochy musíš mít na střeše solary, tu měl být už dávno. Četl jsem, že Francie ho zavádí nebo zavede. Maličkost kterou by platily všechny ty překladišť ní krabice, ale to se u nás nezavede asi nikdy. Na jedné straně není tlak a na druhé straně je lobysticky protitlak.

    No a připočteme k tomu maličkost, že tahle vláda odborníků ani po roce pandemie nebyla schopná vypotit epidemický zákon, tohle je naprosto mimo jejich cokoli.

    TADEAS: nazor ma slozitejsi, o holistic grazing ani zminka, tezko rict proc nadace teda koupila ty triliony hektaru v USA? :)

    Q: In the book you cover a broad array of hard-to-solve sectors. The one I still have the hardest time with, in terms of fully addressing it, is food. The scale is massive. We’ve barely begun. We fundamentally don’t have replacements that completely eliminate the highly potent emissions from burping livestock and fertilizer. How hopeful are you about agriculture?

    A: There are [companies], including one in the [Breakthrough Energy Ventures] portfolio called Pivot Bio, that significantly reduce the amount of fertilizer you need. There are advances in seeds, including seeds that do what legumes do: that is, they’re able to [convert nitrogen in the soil into compounds that plants can use] biologically. But the ability to improve photosynthesis and to improve nitrogen fixation is one of the most underinvested things.

    In terms of livestock, it’s very difficult. There are all the things where they feed them different food, like there’s this one compound that gives you a 20% reduction [in methane emissions]. But sadly, those bacteria [in their digestive system that produce methane] are a necessary part of breaking down the grass. And so I don’t know if there’ll be some natural approach there. I’m afraid the synthetic [protein alternatives like plant-based burgers] will be required for at least the beef thing.

    Now the people like Memphis Meats who do it at a cellular level—I don’t know that that will ever be economical. But Impossible and Beyond have a road map, a quality road map and a cost road map, that makes them totally competitive.

    As for scale today, they don’t represent 1% of the meat in the world, but they’re on their way. And Breakthrough Energy has four different investments in this space for making the ingredients very efficiently. So yeah, this is the one area where my optimism five years ago would have made this, steel, and cement the three hardest.

    Now I’ve said I can actually see a path. But you’re right that saying to people, “You can’t have cows anymore”—talk about a politically unpopular approach to things.

    Q: Do you think plant-based and lab-grown meats could be the full solution to the protein problem globally, even in poor nations? Or do you think it’s going to be some fraction because of the things you’re talking about, the cultural love of a hamburger and the way livestock is so central to economies around the world?

    A: For Africa and other poor countries, we’ll have to use animal genetics to dramatically raise the amount of beef per emissions for them. Weirdly, the US livestock, because they’re so productive, the emissions per pound of beef are dramatically less than emissions per pound in Africa. And as part of the [Bill and Melinda Gates] Foundation’s work, we’re taking the benefit of the African livestock, which means they can survive in heat, and crossing in the monstrous productivity both on the meat side and the milk side of the elite US beef lines.

    So no, I don’t think the poorest 80 countries will be eating synthetic meat. I do think all rich countries should move to 100% synthetic beef. You can get used to the taste difference, and the claim is they’re going to make it taste even better over time. Eventually, that green premium is modest enough that you can sort of change the [behavior of] people or use regulation to totally shift the demand.

    So for meat in the middle-income-and-above countries, I do think it’s possible. But it’s one of those ones where, wow, you have to track it every year and see, and the politics [are challenging]. There are all these bills that say it’s got to be called, basically, lab garbage to be sold. They don’t want us to use the beef label.

    TADEAS: asi by to musel stanovit parlament, jedno ktery, jestli evropsky, nebo narodni. Musi to mit zakonnou formu. Neco jako mas ochranu vodnich zdroju, tak potrebujeme i ochranu klimatu, resp. minimalni, nouzovou, energetickou produkci zakonne.
    Je to vlastne jako kdybychom lpeli na tom, ze obec musi mit cisticku ale uz jsme neresili, jestli je napajena elektrinou alespon pres den ;)
