Recent study present an analysis of “the gap between the CO2 storage required to meet net zero targets and the slow maturation of regional storage resources.”
Researchers estimate that “European storage rates need to boost 30-100x by 2030 to meet #NetZero by 2050. 🇨🇳 & North America face a similar challenge. The slow global progress of #CarbonStorage undermines the latest IPCC, IEA & EU transition pathways to net zero by 2050.”

Here, scientists of this study investigate “if sufficient #storage can be developed in time. China 🇨🇳 (30%), (15%) and Europe 🇪🇺(10%) dominate global #emissions.”
In this study, “Europe was chosen as a data-rich exemplar.”

“Assuming #NetZero in 2050, researchers back-calculate the #storage required under 3️⃣ scenarios of low, medium, and high #CCS demand.”
5/12
“Even the low demand scenario requires 0.2 Gt of #storage by 2030, increasing to 1.3 Gt by 2050. The moderate & high demand scenarios require 5-8 Gt by 2050. The current #CarbonStorage rate in #Europe is 0.001 Gt/yr.”
6/12
So, “there is a huge gap btw policy demand & #storage supply. Adaptation of existing #hydrocarbon tech has the potential to close this gap, with CCS for the entire EU requiring less than half the historic rate of HC exploration & development in UK North Sea from 1980-2010.”
7/12
“Counter to expectation, #storage cannot be delivered by exponential growth but requires an early & sustained investment of 30-50 boreholes per year starting before 2030 to build sufficient capacity,” researchers affirmed.
8/12
“A 5-year lead-time to identify & mature prospects needs policy intervention before 2025. Continued policy deferral will lock Europe into a low CCS pathway that restricts the contribution of #NETs at a potential cost of €100 billion for every gigatonne delayed beyond 2050.”
9/12
According to this research, “North America & China require similar policy intervention to close the gap on #CarbonStorage and #NetZero.”

The Frontier Buyers has teamed up with carbon removal developer Phlair, committing to invest $30.6 million in electrochemical direct air capture to remove 47,000 tons of CO2 from 2027 to 2030.
B.C. Centre for Innovation and Clean Energy launched Canada’s first CDR fund, offering $3M to support early-stage, hard-tech carbon removal solutions for decarbonizing B.C. and Canada.
"Geoengineering isn't just a climate issue—it's a geopolitical chess game. Only US & China have power to unilaterally deploy #SAI at scale."
Will they race to control skies or seek climate diplomacy? New study explores 4 futures🧵1/9
2/ SAI could cool the planet—but who controls it controls global climate security.
Key risks of unilateral deployment:
🔴 Termination shock
🔴 Environmental disruptions
🔴 SAI as a potential weapon
🔴 Geopolitical leverage—both a threat & opportunity
3/ This creates a security gap:
The US & China are locked in great power competition, yet neither has a clear strategy on SAI.
Who moves first? Who controls the stratosphere? The dilemma: Deploy & gain influence—or deter & risk falling behind?

@Arcaclimate has secured $12.2 million from Australian venture capital firms Side Stage Ventures and Saniel Ventures to help scale its carbon removal technology at Western Australian mine sites.
Qualterra, a company that converts organic waste into biochar for soil health and carbon sequestration, secured $4.5M to expand biochar production, launch carbon credits, and scale plant propagation.
🚨What if we could remove methane from the atmosphere—fast?🚨
A new study proposes two ways to use 𝐚𝐭𝐨𝐦𝐢𝐜 𝐜𝐡𝐥𝐨𝐫𝐢𝐧𝐞 to destroy this powerful GHG: one with reactors, the other by releasing chlorine into the air. But one of these ideas comes with serious risks:🧵1/10
2/ Methane is a powerful but short-lived greenhouse gas, responsible for ~0.5°C of global warming. "It’s 80x more potent than CO₂ over 20 years," and its atmospheric levels continue to rise—despite global pledges to cut emissions.
3/ In nature, hydroxyl (OH) radicals break down methane, but the process is slow.
Chlorine (Cl) radicals can do the same job 16x faster, though they are far less abundant in atm—destroying only ~1-4% of methane today.
🚨🐺Scotland’s lost forests could rise again with the help of wolves🐺🚨
A new study finds that reintroducing these apex predators in the Scottish Highlands could restore wild woodlands & capture 𝟏 𝐦𝐢𝐥𝐥𝐢𝐨𝐧 𝐭𝐨𝐧𝐬 𝐨𝐟 𝐂𝐎₂ 𝐚𝐧𝐧𝐮𝐚𝐥𝐥𝐲 (#CDR). Here’s how:🧵1/7
2/ The Scottish Highlands were once a land of towering pines and roaming wolves. But 250 years ago, wolves vanished—and with them, nature’s balance. Red deer, left unchecked, now number 400,000, grazing young trees before they can take root.
3/ Researchers modeled what would happen if wolves returned to the Cairngorms, the Central Highlands, and beyond.
Their findings? 167 wolves could reduce deer numbers enough for forests to regrow naturally—on a vast scale.
