1/ As #OceanCleanUp seeks to make a wave to strengthen its business model,it's important to remember that #plastic pollution is not just a waste issue,which is why a mandate was given to negotiate an agreement that covers the entire life cycle of…
2/ In one of the webinars that I visited recently to prepare for these negotiations, it was said, that there is now overwhelming evidence of health effects at every stage of #plastics lifecycle, nicely put together in the @minderoo report 👇#PlasticsTreaty… Image
3/ In addition, at every stage of its life cycle, #plastics cause #greenhouse gas emmissions, which we super-urgently need to reduce to mitigate the #climatecrisis. This study estimated that plastic caused 4.5% of global #GHG emissions. #PlasticsTreaty…

The conversation about #SouthAfrica's looming #electricitycrisis HAS to include coal.

Here's why: 🧵🧵 Image

Our energy sector is the 🥈 highest Green House Gas emitter of all the World's Industrializing countries (the G20) 🥲🌍🥲. Coal is responsible for roughly 85% of our energy generation 🤯.


👇🏻👇🏻👇🏻… Image

Coal is becoming less #efficient 📉
Its increasing Energy Return on Investment (or EROI) means that a higher energy input is needed to generate electricity!
The exact opposite of #renewable energy☘️… 🙄🙄

"The recent review article discusses the basic operation of the marine #CarbonCycle & 2 #mCDR methods that are "thought to offer the greatest potential in terms of #CDR mass:

1/14 ImageImage
Various conclusions were drawn in the review which are enlisted below:

1️⃣ "The alkalinity of the ocean creates a massive increase in the ocean’s capacity to #store #carbon, relative to a scenario without #OceanAlkalinity."
2/14 Image
2️⃣ "Ocean warming causes decreases in both #CO2 #solubility and the Revelle factor (B), which make the ocean less efficient at #absorbing CO2."

The Climate Change Authority of #Australia has issued a report that pinpoints #CarbonSequestration as critical to reduce emissions.

"Storing C away from the atm is integral, both to avert #GHGs from entering the atm & to #remove them from it."
1/11 Image
The report notes that "while conventional #CarbonAccounting is simple and economically flexible, it does not consider crucial differences between different sources and sinks of #GHG #emissions." As a result, 𝐈𝐭 𝐩𝐫𝐨𝐩𝐨𝐬𝐞𝐬 𝐭𝐡𝐞 𝐟𝐨𝐥𝐥𝐨𝐰𝐢𝐧𝐠 𝐚𝐜𝐭𝐢𝐨𝐧𝐬: ⬇️
1️⃣ "The Government should prioritise the development of long-lived geological and mineral #storage technologies.

2️⃣ Measures to restore CO2 released from #CarbonSinks should be reviewed and enhanced as appropriate."

Accordingly, "the #bioenergy production potential and #GHG emission reduction for each distinct type of #biomass feedstock through different conversion pathways were estimated in the study."
2/6 Image
"The sum of all available organic waste (21.55EJ/yr) & energy plants on marginal land (11.77EJ/yr) in China produced 23.30EJ of #bioenergy & reduced 2535.32Mt CO2-eq emissions, accounting for 19.48% & 25.61% of China’s T energy production & C emissions in 2020, respectively."

"A promising solution to nullify the net embodied #GHG emissions of civil infrastructure is the use of C-negative materials for concrete manufacturing. C-neutral coal ash & agriculture/forestry by-products, like #biochar, exhibit a high CO2 uptake potential."
1/8 Image
📝 A lately published paper aimed "to explore the viability of using #biochar as a #CarbonSink and to develop carbon-neutral #concrete with improved performance."
📉 Experimental findings suggest that "the optimal amount of biochar (1%) slightly improves hydration and mechanical properties, but the combination with mineral additives significantly enhances the performance."

Our analysis of materials released by @IESO_Tweets in response to our Freedom of Information Request

1. Thirty-two Ontario municipalities, representing almost 60% of Ontario’s population, have asked @ONgov to phase-out gas-fired electricity generation. 1/

2. According to Ontario’s Independent Electricity System Operator’s (IESO) October 7, 2021 (misleading) report,Decarbonization and Ontario’s Electricity System, phasing-out gas power by 2030 would raise residential electricity bills by 60% [page 1].

Last week, @IPESfood published a report exploring widespread #protein claims.

The report discussed 8 claims, but media coverage focused on criticizing meat alternatives as an ineffective climate solution—a claim also pushed by #livestock groups.👇 1/10
🚫An expert panel warns that fake #meat will not save the planet, @KatyAskew1 reports via @FoodNavigator.

According to the article, the report shows that "alternative proteins aren’t necessarily the silver bullet solution they have been billed as." 2/10…
🔍According to the latest @IPCC report, cultured meat and #PlantBased alternatives to animal products "can bring substantial reduction in direct #GHG emissions from food production."

If you ever wanted to acquire #carbonoffsets, you've surely faced the question of categorization. Here is an easy taxonomy 👇 🧵
1/ Two weeks ago I highlighted the difference between carbon emission reduction and removal projects.

The idea of #CarbonReduction is to pay others to reduce emissions in your place. But your output remains in the system. One plus zero.
2/ #CarbonRemoval on the other hand scrubs carbon directly from the atmosphere. Plus one, minus one.

But technically, the #carbonmarket makes no difference. A ton is a ton.

Major companies’ #NetZero climate pledges largely fail test. 🚨 Our Corporate Climate Responsibility Monitor, launched today w/ @CarbonMrktWatch, finds: Companies have an immense potential for #ClimateAction but pledges lack transparency + integrity. 🧵⤵️…
2/ Background: Companies are increasingly alert to the #climatcrisis, facing calls to take responsibility for their environmental impact. The companies assessed in the report are major multinationals contributing to roughly 5% of global #GHG emissions.
3/ The #CCRM1 shows: Climate pledges of these 25 corporations on average only commit to emissions reductions of 40%, not ❌ 100% as suggested by their #netzero and #carbonneutral pledges. Collectively, they commit to reducing only <20% of their 2.7 GtCO2e emission footprint.

1) #HBARbarians! Let’s talk #NFTs. #NFT skeptic? 🧐Read this 🧵. NFTs go far beyond #jpeg & are the future of #Web3, “gateway” to #crypto, & will be larger than #cryptocurrencies. This aims to educate #Hedera community & raise awareness to our #HBAR #NFTartists. Wallet flex 💪👇
2) #HBARbarians who think #NFTs are a bubble or do not want to buy an #NFT. That's fine. But #NFTs are vitally important for #HBAR to appreciate in value. See #Solana ($SOL) this year? Yep, #NFTs 🤯 (1)
3) Even if you don't buy an #NFT, you can help. See a #Hedera artist whose art resonates w/ you? Simply hit "like", "RT", or "comment" something nice. It goes a long way in ushering in new #HBAR buyers & #NFTartists.

2) The @UN has set a 2050 net zero carbon goal…

The @WhiteHouse has set a 50-52% reduction in GHG pollution by 2030.…

Many states set their own 100% clean energy goals.… ImageImage
3) These goals are ambitious. We can't just stop using fossil fuels yet. Currently renewable & clean energy sources are not abundant enough to meet our 🌎 energy demands. During this bridge from "dirty" to "clean" energy - carbon offsets, sequestration & other removal are vital. ImageImage

We understand the anger against politicians at #COP26 for delivering a weak, inadequate #ClimateChange agreement. But blaming individual decision-makers ignores the fact that the system rewards failure. Here’s how we tackle that reality. 🧵 (1/15)
Here’s the problem: the profits of the #FossilFuel economy are kept largely separate from its costs. That means that countries/companies/investors who generate products and burn fuels that cause #ClimateChange pocket the profits while others pay the price. 💵 (2/15)
As a result, #FossilFuels appear profitable, and there’s massive incentive for political and economic structures to treat these industries as wealth creators. Which creates incentives for climate denial, downplaying the role of the #FossilFuel industry, etc. (3/15)

Only a few days into @COP26, we’re already hearing global commitments and plans. This will all culminate in a day dedicated to the built environment next week. In the meantime, I’ll share my #COP26 thoughts in this thread.
I encourage you all to explore this wonderful virtual exhibition of the world's greenest buildings at @COP26. These projects serve as examples to all of us in the real estate and building sectors. @wef…
As I’ve said many times, @COP26 must be a turning point for the real estate industry. Buildings are responsible for 40% of carbon emissions worldwide. Action from this industry is crucial to meeting climate goals.…

Long🧵on the provisions of #BuildBackBetter on all things #electricity & #grid. The act starts w/ ~3bn in loans for electric co-ops @NRECANews, incl. projects w/ #batteries. Co-ops have been very involved in @ENERGY-funded R&D & are now enabled to bring results to practice! 1/
It is funny that in my postdoc work @CMU_ECE & @NRECANews w/ @eeregov funding, we actually studied the added value of #battery to #photovoltaics for residential customers' energy cost savings:… & [1],[3], [4] here… 2/
Another ~10bn to co-ops for loans until 2031 to improve #resilience & #reliability w/ investments in #renewables & #transmission . Co-ops 'own' transmission lines & this money can motivate adjacent upgrades. Also critical that #renewables & #transmission appear together here! 3/
