BREAKING NEWS! Happy Europe Day 🥰: European Parliament adopts my proposal to reduce #methane emissions! We are determined to stop the climate killer methane. Thank you to all shadow rapporteurs*! Good day for climate + energy sovereignty! This is what we want: 🧵 Image
Fossil imports: entire supply chain must be tackled, also outside EU. Without extension to imports, Methane Regulation stays piecemeal! Application to imports reduces global methane emissions by 400 million t CO2 equivalents per year = 2/3 Germany’s emissions 2/
Methane venting + flaring as routine? To be abolished! Only allowed in exceptional cases.
Leaking valves, holes in pipelines? Regular inspections with highly sensitive measuring devices prescribed, strict specifications for quick repair.

1/ Last month, NYC launched its first curbside #composting effort in Queens, with the goal of expanding across the city to keep the 8M pounds of residential #FoodWaste generated daily from rotting in #landfills and createing #climate damaging emissions.
2/ After the food scraps are collected, they’re sent to one of two #AnerobicDigestion facilities, where bacteria break down #organic materials in the absence of oxygen to creates a mixture of gases – or #biogas, which can be burned to produce #energy.
3/ But, as @LFO has made clear, #AnerobicDigestion can get tricky. Particularly when #FoodScraps are sent to the #digesters at wastewater treatment plants, which are used to reduce the volume of #SewageSludge. This is happening in NYC.

How much has each country contributed to climate change through historical #emissions of #carbon dioxide, #methane and nitrous oxide?

Today, our new 'living' dataset for tracking national contributions to #warming is published in @ScientificData @Peters_Glen @robbie_andrew @JoGuetschow @PFriedling @cleque
@ScientificData We provide estimates of the #warming caused by historical #emissions of #CO2, #CH4 and #N2O by 226 countries, for every year since 1850.

National warming contributions are further split into #fossil or #land use, land use change and #forestry (LULUCF) sources. @Peters_Glen @robbie_andrew @JoGuetschow @PFriedling @cleque
@ScientificData The top contributors to #warming up to 2021, through #emissions of all three gases since 1850, were:

USA: 0.28°C / 17% of the warming caused by all global emissions
China: 0.20°C / 12%
Russia: 0.10°C / 6%
Brazil & India: 0.08°C / 5%
🇮🇩 , 🇩🇪 , 🇬🇧 , 🇯🇵 , 🇨🇦 : 0.03-0.05°C each @Peters_Glen @robbie_andrew @JoGuetschow @PFriedling @cleque

🚨Study on future options and costs of energy imports for Germany🚨

Our study comparing future options for energy imports to Germany and their costs has finally passed peer-review and is now published.

A thread 🧵
🔑Key findings

- Germany has many options for import
- No one-size-fits-all: Costs strongly depend on what and from where you import
- Costs for renewable alternatives and prices for fossil counterparts converged in last year

Why did #methane surge in 2020 ?

Our article just published @Nature shows that the high growth rate of CH4 in 2020 is explained half by decreased OH removal & half by more wetland emissions @ShushiPeng @CEA_Officiel @gcarbonproject @IPSL_outreach … 🧶… Image
We expected in 2020 less anthropogenic emissions from #COVID but in fact the #CH4 growth rate was record high at 15.1 ppt y-1 (@NOAA data ) Image
The #CH4 growth rate results from an imbalance between emissions ( natural and anthropogenic ) and the OH sink in the atmosphere @gcarbonproject Image

🧵All COPs are disappointing; they never do enough to slow warming to keep the planet and its people safe. Year after year, COPs show the power of the fossil fuel industry and its cruel indifference to the planetary suffering it is causing & the climate chaos it will soon unleash
But if you look hard enough, it’s possible to see several positive outcomes from #COP27 . This COP made important progress on several key fronts, inc holding the line on 1.5°C & noting tipping points incl in the cryosphere.…
#COP27 also made progress on #methane, mostly outside the COP: 150 countries plus the EU are now part of the #GlobalMethanePledge, including vulnerable islands & other states

Let's get into one of the most far reaching pieces of regulatory action from @EPA. 3 areas stand out:

1) Comprehensive - every possible #methane source is covered, no loopholes
2) Embraces tech innovation even under uncertainty
3) Acknowledges & corrects for EPA blind spots
All O&G #methane sources are covered, including low producing sites & often owned by small, independent companies. Research has show these type of sites can be a significant source of emission, and until recently, was exempted from all regs.

Not anymore.…
Changing definitions: This may be in the weeds but a huge shift in accounting for #methane. Policy stringency now depends on physical number of equipment on facilities and not arbitrary baseline emissions.

This significantly improves policy effectiveness & compliance monitoring.

‼️SUBMISSIONS DUE BY 5PM - tips in 🧵

The NSW EPA has the power to make reducing #coal mine #methane a priority in its new climate plan. Even a super short submission makes a difference:

#GlobalMethanePledge #MoveBeyondCoal
Ask the EPA to use its authority to take quick action to:

1. Reduce NSW coal mine methane at least 75% by 2030, the amount the IEA says is required for Net Zero by 2050.

2. Recommend no new coal mines or expansions be approved.
3. Require coal companies to cut their methane emissions using all available technology.

4. Require companies to actually measure and transparently report their emissions.

🗓️ The deadline for @Europarl_EN amendments to the @EU_Commission #methane regulation proposal is this Wednesday!🗓️

MEPs have outspokenly supported strong methane action, and policymakers can help strengthen the proposal. Some of the main amendments we'll be looking for 👇
1. Step up methane monitoring + reporting.
Europe must monitor methane emissions based on direct measurement and in line with OGMP 2.0 standards.

Innovations like @MethaneSAT will support these efforts and boost climate transparency and accountability.
2. Plug methane leaks.

Many methane emissions from oil and gas stem from persistent leaks. To #CutMethaneEU, Europe needs to enforce leak detection and repair requirements in line with best international practice.

"Our imagination does´nt has any scenario left in which this could not be a targeted attack" @Tagesspiegel quotes a person involved in the assessment of the German gov regarding the incidents at the #Nordstream #pipelines in the #Balticsea

A first thread ⚠️ #Druckabfall
Yesterday, authorities acknowledged a decrease in pressure in both pipelines; first in NS2, later also in NS1. The 3(!) leakages are to be found in the East of Danish Bornholm (NS2), and also two leaks in the Northeast of the Island (NS1)
Two leaks are within the Danish Exclusive Economic Zone (EEZ), one is in the Swedish EEZ. Sea depth in the region is around 50m.

1/ What the average observer of the #Ethereum merge to Proof of Stake needs to know when considering all the headlines & fanfare about “reduced energy consumption” and then asking “why doesn’t #Bitcoin do this too?”, is that #ETH and $BTC are fundamentally different assets/tools.
2/ #Bitcoin and #Ethereum are not like “Coca Cola and Pepsi”. They are not interchangeable brands of the same type. They are designed and have evolved to achieve very different things. Their context and needs are different, and how we asses them needs to be guided by this.
3/ #Ethereum has evolved and aspires to be a base technological layer for development of creative assets like NFTs, and to enable venture capitalists and others a way to financialize, exchange, and bet on these within the structures of our current monetary & financial systems.

Here are #methane details:

- $850M to EPA for methane monitoring/mitigation
- Fee at $900/t in 2024 going up to $1500/t in 2026.
- EPA methane regs compliant facilities exempt if equivalence can be demonstrated
- EPA required to update inventory estimates in 2 years
Here's the thing:

$900/t CH4 in 2024 is ~$17/mcf of gas, roughly 2x current Henry Hub price. That's a strong incentive for #methane reductions.

$1500/t CH4 is ~$29/mcf. These high prices will incentivize operational changes (e.g., switch gas engines to electric drive motors).
Fees applied to emissions intensities over:
- Production: 0.2% of gas, 10 mt/mbbl of oil
- Transmission: 0.11%
- LNG & other facilities: 0.05%

Only facilities reporting to EPA (>25000 mt CO2e/year emissions) will be subject to #methane fees.
